    Rugged, intelligent shovels offer better productivity and help mine operators avoid costly downtime in a very tight market. In 2007 P & H Mining Equipment began to produce a new breed of electric mining shovels designed to help reduce operating cost in coal and other mining operations. These were designated the P & H C-Series. All have an advanced communication, command and control system called the Centurion system. Coal mining applications for this series include 4100XPCs in Australia, China and Wyoming, USA. The Centurion system provides information on shovel performance and systems health which is communicated via graphic user interface terminals to the operators cab. Bucyrus International is developing a hydraulic crowd mechanism for its electric shovels and is now field testing one for its 495 series shovel. The company has also added greater capability in the primary software in the drive system for troubleshooting and fault identification to quickly diagnose problems onboard or remotely. 4 photos.

  4. Small surface coal mine operators handbook. Final report

    SciTech Connect (OSTI)

    Tourbier, J.T.; Westmacott, R.

    1980-06-01

    The purpose of this handbook is to interpret the Regulations of the Surface Mining Control and Reclamation Act of 1977 (Public Law 95-87) (hereafter referred to as the Act) as they affect the operators of small surface coal mines. Further, the purpose of this handbook is to make it easier for the small operator to compare his operation with the act in order to determine compliance with the regulations. Part 795 of the Regulations deals specifically with the Small Operator Assistance Program. This program relieves the operator of the cost of carrying out certain hydrologic and geologic analyses required by the Regulations. The emphasis of this handbook is on the protection of water resources during mining and reclamation operations. As almost all the operations in surface mining directly or indirectly affect water the authors have included some operations which may only marginally affect water quality or hydrology. Anthracite mining, lignite mining, coal processing, refuse disposal, and slurry disposal are not covered in this handbook.

  5. Hydraulically operated mine prop with safety valve

    SciTech Connect (OSTI)

    Koppers, M.; Marr, P.

    1981-02-24

    A mine prop is disclosed that is provided with an overpressure valve of large flowthrough section which opens when excessive forces suddenly act on the prop to discharge pressure fluid from the interior of the prop. The overpressure valve comprises a hollow cylindrical housing forming at one end a valve seat communicating with the fluid-filled inner space of the prop and a valve member axially guided in the housing for movement between a closed position engaging the valve seat and an open position. The fluid-filled space of the prop communicates with channels leading to the outside of the prop. The valve member is normally maintained in the closed position by a gas pillow under high pretension confined in a pressure space delimited peripherally by the wall of the valve housing and at opposite ends respectively by the valve member and a plug fluid tightly mounted in and closing the other end of the housing. The valve member and the plug are both formed from metal and are both provided at facing ends with annular slender sealing lips of triangular cross-section tapering toward each other, the outer surfaces of which are pressed into engagement with the inner peripheral surface of the housing by the pressure of the gas pillow.

  6. INTEGRATED ROBOT-HUMAN CONTROL IN MINING OPERATIONS

    George Danko

    2005-04-01

    This report contains a detailed description of the work conducted in the first year of the project on Integrated Robot-Human Control in Mining Operations at University of Nevada, Reno. This project combines human operator control with robotic control concepts to create a hybrid control architecture, in which the strengths of each control method are combined to increase machine efficiency and reduce operator fatigue. The kinematics reconfiguration type differential control of the excavator implemented with a variety of ''software machine kinematics'' is the key feature of the project. This software re-configured excavator is more desirable to execute a given digging task. The human operator retains the master control of the main motion parameters, while the computer coordinates the repetitive movement patterns of the machine links. These repetitive movements may be selected from a pre-defined family of trajectories with different transformations. The operator can make adjustments to this pattern in real time, as needed, to accommodate rapidly-changing environmental conditions. A Bobcat{reg_sign} 435 excavator was retrofitted with electro-hydraulic control valve elements. The modular electronic control was tested and the basic valve characteristics were measured for each valve at the Robotics Laboratory at UNR. Position sensors were added to the individual joint control actuators, and the sensors were calibrated. An electronic central control system consisting of a portable computer, converters and electronic driver components was interfaced to the electro-hydraulic valves and position sensors. The machine is operational with or without the computer control system depending on whether the computer interface is on or off. In preparation for emulated mining tasks tests, typical, repetitive tool trajectories during surface mining operations were recorded at the Newmont Mining Corporation's ''Lone Tree'' mine in Nevada.

  9. Underground coal operators install several new longwall mining systems

    SciTech Connect (OSTI)

    Fiscor, S.

    2008-02-15

    Several new names appear in the annual US Longwall Census, but the population remains the same: 52 although the number of longwall mines dropped from 40 to 47. CONSOL Energy remains the leader with 12 faces. Robert E. Murray owns 8 longwall mines followed by Arch Coal with 5 and Foundation Coal with 3. West Virginia has 13 longwalls followed by 9 in Pennsylvania, 7 in Utah and 6 in Alabama. The article describes CONSOL Energy's operations. A detailed table gives for each longwall installation, the ownership, seam height, cutting height, panel width and length, overburden, number of gate entries, depth of cut, model of equipment used (shearer, haulage system, roof support, face conveyor, stage loader, crusher, electrical controls and voltage to face). 2 tabs.

  10. A waterjet mining machine for use in room and pillar mining operations

    SciTech Connect (OSTI)

    Summers, D.A.

    1990-06-01

    A new mining machine is constructed for use in room and pillar mining operations. This machine uses the action of computer controlled, centrally located high pressure cutting lances to cut deep slots in a coal face. These slots stress relieve the coal ahead of the machine and outline blocks of coal. The movement forward of the machine then wedges up the lower block of coal. This wedging action is assisted by the gathering arms of the loader section of the machine, and by underlying oscillating waterjets which create a slot ahead of the loading wedge as it advances. Finally the top section of coal is brought down by the sequential advance of wedge faced roof support members, again assisted by the waterjet action from the central cutting arms. The machine is designed to overcome major disadvantages of existing room and pillar mining machines in regard to a reduction in respirable dust, the creation of an immediate roof support, and an increase in product size, with concomitant reduction in cleaning costs.

    1984-01-01

    Between 1967 and 1978 use of longwall methods to mine coal in the United States continually increased. Although these methods offer several advantages, health hazards often exist because of unique and difficult problems in the control of respirable dust. This paper discusses the results of respirable dust studies conducted on United States longwall mining operations in 1972 and 1978. Prevalent engineering control methods (ventilation, water application and use of machine cutting parameters) and administrative controls for minimizing employees' respirable dust exposure are discussed. Current research efforts for the control of respirable dust on longwall mining operations are reviewed. 21 figs.

    Results obtained from radiometric research carried out from 1980-81 in the region of U mines in the Val Vedello are provided. Data are presented on /sup 2/)2''/sup 2/Rn, /sup 226/Ra and natural U concentrations in spring and surface waters. Concentrations were found to be relatively low. There is some increase in the vicinity of the exploratory U mine but this is, at least up to the present, only of a local character. Data are presented on external gamma exposure, /sup 210/Pb and /sup 210/Po in foodstuffs and in the urine of normal and exposed population as well as /sup 226/Ra in milk and vegetable samples. The aim of this study is to outline a preliminary map of natural radioactivity on the site before starting the mining activity. This will enable us later to detect changes caused by the U mining, milling and mill-tailing disposal operations.

  15. Surface coal mining operations in two Oklahoma Counties raise questions about prime farmland reclamation and bond adequacy

    SciTech Connect (OSTI)

    1985-08-08

    The Surface Mining Control and Reclamation Act of 1977 allows prime farmland to be mined but requires the coal operator to reclaim it according to special reclamation standards. To be considered prime farmland, the soil must meet the Secretary of Agriculture's definition of prime soil and have historically been used for intensive agricultural purposes. In Oklahoma, the historical-use provision has generally been applied to lands that have been used for cropland for 5 of the preceding 10 years. GAO's review of mining activities in two Oklahoma counties showed that the land comprising 54 of the 58 mine permits issued since the act's passage contained some prime soil. None, however, required reclamation to prime farmland standards because landowners signed letters stating that the land had not been farmed for crops for five of the preceding 10 years. GAO also found that numerous sites in the two counties were abandoned by mining companies after the act was passed. Since abandonment, no reclamation has occurred on most of these sites. The Department of the Interior's Office of Surface Mining questions whether the bonds on the unreclaimed sites, if collected, will be adequate to do the necessary reclamation. Oklahoma's Department of Mines has taken action to increase bond amounts on newly-issued permits and on some older permitted areas in order to prevent future reclamation problems.

  16. New EPA Guidelines for Review of Surface Coal Mining Operations in Appalachia (released in AEO2010)

    Reports and Publications (EIA)

    2010-01-01

    On April 1, 2010, the Environmental Protection Agency (EPA) issued a set of new guidelines to several of its Regional offices regarding the compliance of surface coal mining operations in Appalachia with the provisions of the Clean Water Act (CWA), the National Environmental Policy Act, and the environmental justice Executive Order (E.O. 12898). The stated purpose of the guidance was to explain more fully the approach that the EPA will be following in permit reviews, and to provide additional assurance that its Regional offices use clear, consistent, and science-based standards in reviewing the permits. Although the new guidelines go into effect immediately, they will be subjected to review both by the public and by the EPA's Science Advisory Board, with a set of final guidelines to be issued no later than April 1, 2011.

    1995-12-31

    A major environmental concern leading to the enactment of the Surface Mining Control and Reclamation Act of 1977 (SMCRA) was the degradation of streams and waterways from discharges of acid mine drainage (AMD) resulting from coal mining operations. Although SMCRA and its regulatory scheme contains specific provisions addressing the drainage of acidic water from mine sites, as do various other agencies statutes and regulations, AMD from active and abandoned mines remains a major environmental problem in the Appalachian region. The formation of acidic water during coal mining operations is pervasive and some believe impossible to prevent.

  8. Ground control for highwall mining

    SciTech Connect (OSTI)

    Zipf, R.K.; Mark, C.

    2007-09-15

    Perhaps the greatest risk to both equipment and personnel associated with highwall mining is from ground control. The two most significant ground control hazards are rock falls from highwall and equipment entrapment underground. In the central Appalachians, where the majority of highwall mining occurs in the USA, hillseams (or mountain cracks) are the most prominent structure that affects highwall stability. The article discusses measures to minimise the risk of failure associated with hillstreams. A 'stuck' or trapped highwall miner, and the ensuring retrieval or recovery operation, can be extremely disruptive to the highwall mining process. Most entrapment, are due to roof falls in the hole. The options for recovery are surface retrieval, surface excavation or underground recovery. Proper pillar design is essential to maintain highwall stability and prevent entrapments. NIOSH has developed the Analysis of Retreat Mining Pillar stability-Highwall Mining (ARMPS-HWM) computer program to help mine planners with this process. 10 figs.

    Productive mines in the southwest deplete reserves, while the government drags its heels on new power projects. Production in Arizona and New Mexico has fallen 18% over the last four years to 34.1 million tons. With Chevron Mining's McKinley mine rapidly depleting its reserves the industry will continue to contract. In the last three years at least three large mines in the Four Corners have terminated operations. Three others remain captive operations: BHP Billiton's San Juan Underground and Navajo Surface operations and Peabody Energy's Kayenta surface mine. In 2006 the Black Mesa mine stopped producing coal. These four mines are isolated from the national railways. Peabody's new El Segundo surface mine near Grants, NM is increasing production. If the planned $3 billion Desert Rock coal-fired power plant is built this will present a new market for the Navajo mine. The article gives details about the state of the aforementioned mines and of the new King II coal mine on the northern periphery of the San Juan basin and discusses the state of plans for the Desert Rock Energy Project. 5 photos.

  13. Remining to reclaim abandoned mined lands: Virginia`s initiative

    SciTech Connect (OSTI)

    Zipper, C.E.; Lambert, B.

    1998-12-31

    Abandoned Mined Lands (AML) are lands that were mined prior to implementation of the federal Surface Mining Control and Reclamation Act (SMCRA) in 1977, but were inadequately reclaimed. Re-mining of AML is being conducted on a routine basis by coal-mining operations in eastern states such as Virginia. Re-mining is a potentially important means of reclaiming AML. However, under current policies, re-mining operations often fail to permit and reclaim priority 1, 2, and 3 AML, especially those areas which present the most severe environmental problems. This paper describes policy issues which affect the potential for AML reclamation by re-mining operations in mountainous mining areas, such as Virginia; efforts underway in Virginia which seek to resolve those issues; and progress achieved to date under that initiative.

  14. Surface mine regulations complicate reclamation

    SciTech Connect (OSTI)

    Seltz-Patrash, A.

    1980-09-01

    The Surface Mining Control and Reclamation Act of 1977 is a landmark environmental law intended to protect U.S. lands from stripmining effects. However, coal mine operators claim that some SMCRA regulations are misguidedcosting time and money, but yielding no substantial environmental benefit. Unlike other environmental acts, SMCRA details specifically the goals of reclamation and the methods that must be implemented to meet these goals. Coal industry representatives believe that this discourages innovation, promotes inefficiency by ignoring regional differences among sites, and results in unnecessary expense to the industry. Reclamation practices and progress among western coal mining companies are evaluated. (1 map, 5 photos)

    A comprehensive mine-wide, two-way wireless voice and data communication system for the underground mining industry was developed. The system achieves energy savings through increased productivity and greater energy efficiency in meeting safety requirements within mines. The mine-wide system is comprised of two interfaced subsystems: a through-the-earth communications system and an in-mine communications system. The mine-wide system permits two-way communication among underground personnel and between underground and surface personnel. The system was designed, built, and commercialized. Several systems are in operation in underground mines in the United States. The use of these systems has proven they result in considerable energy savings. A system for tracking the location of vehicles and people within the mine was also developed, built and tested successfully. Transtek's systems are being used by the National Institute of Occupational Safety and Health (NIOSH) in their underground mine rescue team training program. This project also resulted in a spin-off rescue team lifeline and communications system. Furthermore, the project points the way to further developments that can lead to a GPS-like system for underground mines allowing the use of autonomous machines in underground mining operations, greatly reducing the amount of energy used in these operations. Some products developed under this program are transferable to applications in fields other than mining. The rescue team system is applicable to use by first responders to natural, accidental, or terrorist-caused building collapses. The in-mine communications system can be installed in high-rise buildings providing in-building communications to security and maintenance personnel as well as to first responders.

    Although standards and regulations are in place to prevent large mining equipment fires, recent analyses of mine accident data show that mining equipment fires still occur with alarming frequency and grave consequences, particularly at all surface mines and in underground metal/nonmetal mines. Recently technological advances in fire protection, combined with the statistical data on equipment fires, led NIOSH to reinvestigate this and to improve operator safety. NIOSH demonstrated that newly developed technologies, such as dual cab fire inerting systems and engine compartment fire barriers, can greatly enhance operator safety and lessen the damage of property during large mobile equipment fires. 10 refs., 5 figs.

    Recovery of coal from mine wastes produced by historic longwall mines in northeastern Illinois was studied as part of a project undertaken in 1982 for the Illinois Abandoned Mined Lands Reclamation Council. About 100 of these mines operated in the Wilmington and La Salle Districts of the Illinois Coal Field between about 1870 and 1940; all worked the Colchester (No. 2) Coal Seam, using a manual high-extraction mining method. Large samples of the three major kinds of mine waste - gray mining gob, preparation gob, and preparation slurry - were collected from deposits at nine of the larger mine sites and analyzed to determine their general ranges of sulfur, ash, and heating values. Preparation gob and slurry from six of the sites had significant combustible contents, and were evaluated by a simple procedure in which ash analyses and wet-screening tests were used to determine the washability and yield of combustibles to recovery processes.

    The knowledge-based expert systems (KBES) is a potentially powerful technique to the mining engineer in traditional areas of mine design and operations, as well as in the emerging areas of mining automation and robotics. Since KBES is still experimental in many respects, caution must be exercised as this ''high tech'' tool is developed and applied to mining. The objective of this paper is to demystify expert systems by introducing the elements of KBES, discussing the strengths and weaknesses, and identifying some areas of application in mining, based on the authors' experiences.

  1. Longwall mining of thin seams

    Thin seam operations pose a challenge to the ingenuity of mining engineers to overcome the factor of human inconvenience in the restricted environment and associated high cost production. Surprisingly, low seam longwalls in the Federal Republic of Germany in an average thickness of 35 in. and dipping less than 18/sup 0/ come close to achieving the average production rate of all German longwall operations. They are all plow faces, and a consistent production of 3300 tons per day and a productivity of 40 tons per man shift are reported from one of the thin seam longwalls. These results were attained by reliable high-capacity equipment and roof support by shields that can be collapsed to as low as 22 inches. Maximum mining height for plow operated faces lies at 31.5 inches. Technology for mechanized mining of flat lying coalbeds less than 31.5 inches in thickness without rock cutting is not available, and firmness of coal, undulation of the strata, coalbed thickness variation, and the necessity of cutting rock, particularly through faults, set limits to plow application. The in-web shearer can be used in firm coal to a minimum mining height of 40 inches, and a daily production of 1650 to 2200 tons is reported from a longwall in the Saar district of Germany equipped with such a shearer and shields. Numerous in-web shearers are employed in the United Kingdom; reports as to their success are contradictory. Also, experience in the United States, though limited, has been negative. The steady increase in output from single drum shearer faces in Pennsylvania is a remarkable achievement, and occasional record breaking peaks in production indicate the potential of such mining. Technology development for the future is discussed.

    A method of sublevel caving and pillar and top coal extraction for mining thick coal seams includes the advance mining of rooms and crosscuts along the bottom of a seam to a height of about eight feet, and the retreat mining of the top coal from the rooms, crosscuts and portions of the pillars remaining from formation of the rooms and cross-cuts. In the retreat mining, a pocket is formed in a pillar, the top coal above the pocket is drilled, charged and shot, and then the fallen coal is loaded by a continuous miner so that the operator remains under a roof which has not been shot. The top coal from that portion of the room adjacent the pocket is then mined, and another pocket is formed in the pillar. The top coal above the second pocket is mined followed by the mining of the top coal of that portion of the room adjacent the second pocket, all by use of a continuous miner which allows the operator to remain under a roof portion which has not been shot.

    This invention resulted from a contract with the United States Department of Energy and relates to a mining tool. More particularly, the invention relates to an assembly capable of drilling a hole having a square cross-sectional shape with radiused corners. In mining operations in which conventional auger-type drills are used to form a series of parallel, cylindrical holes in a coal seam, a large amount of coal remains in place in the seam because the shape of the holes leaves thick webs between the holes. A higher percentage of coal can be mined from a seam by a means capable of drilling holes having a substantially square cross section. It is an object of this invention to provide an improved mining apparatus by means of which the amount of coal recovered from a seam deposit can be increased. Another object of the invention is to provide a drilling assembly which cuts corners in a hole having a circular cross section. These objects and other advantages are attained by a preferred embodiment of the invention.

    This report was written in response to a mandate in section 708 of the Surface Mining Control and Reclamation Act of 1977 which required the study of surface coal mining conditions in the State of Alaska, in order to determine which, if any, of the provisions of the Act should be modified with respect to surface coal mining operations in Alaska. The report discusses both surface mining and the surface effects of underground mining. The report examines not only the impact of mining at the site of operations but also the effects that extend beyond the mine itself, including effects on social institutions, the economy, the physical well-being of people, and the use of land. The report considers Alaska conditions primarily from the perspective of a potential increase in coal development, not of mining limited to meeting local needs of energy.

    Cost estimating equations were developed to determine capital and operating costs for five surface coal mine models in Central Appalachia, Northern Appalachia, Mid-West, Far-West, and Campbell County, Wyoming. Engineering equations were used to estimate equipment costs for the stripping function and for the coal loading and hauling function for the base case mine and for several mines with different annual production levels and/or different overburden removal requirements. Deferred costs were then determined through application of the base case depreciation schedules, and direct labor costs were easily established once the equipment quantities (and, hence, manpower requirements) were determined. The data points were then fit with appropriate functional forms, and these were then multiplied by appropriate adjustment factors so that the resulting equations yielded the model mine costs for initial and deferred capital and annual operating cost. (The validity of this scaling process is based on the assumption that total initial and deferred capital costs are proportional to the initial and deferred costs for the primary equipment types that were considered and that annual operating cost is proportional to the direct labor costs that were determined based on primary equipment quantities.) Initial capital costs ranged from $3,910,470 in Central Appalachia to $49,296,785; deferred capital costs ranged from $3,220,000 in Central Appalachia to $30,735,000 in Campbell County, Wyoming; and annual operating costs ranged from $2,924,148 in Central Appalachia to $32,708,591 in Campbell County, Wyoming.

    CONSOL Energy Inc., in conjunction with MEGTEC Systems, Inc., and the U.S. Department of Energy with the U.S. Environmental Protection Agency, designed, built, and operated a commercial-size thermal flow reversal reactor (TFRR) to evaluate its suitability to oxidize coal mine ventilation air methane (VAM). Coal mining, and particularly coal mine ventilation air, is a major source of anthropogenic methane emissions, a greenhouse gas. Ventilation air volumes are large and the concentration of methane in the ventilation air is low; thus making it difficult to use or abate these emissions. This test program was conducted with simulated coal mine VAM in advance of deploying the technology on active coal mine ventilation fans. The demonstration project team installed and operated a 30,000 cfm MEGTEC VOCSIDIZER oxidation system on an inactive coal mine in West Liberty, WV. The performance of the unit was monitored and evaluated during months of unmanned operation at mostly constant conditions. The operating and maintenance history and how it impacts the implementation of the technology on mine fans were investigated. Emission tests showed very low levels of all criteria pollutants at the stack. Parametric studies showed that the equipment can successfully operate at the design specification limits. The results verified the ability of the TFRR to oxidize {ge}95% of the low and variable concentration of methane in the ventilation air. This technology provides new opportunities to reduce greenhouse gas emissions by the reduction of methane emissions from coal mine ventilation air. A large commercial-size installation (180,000 cfm) on a single typical mine ventilation bleeder fan would reduce methane emissions by 11,000 to 22,100 short tons per year (the equivalent of 183,000 to 366,000 metric tonnes carbon dioxide).

    This paper examines the efficacy of the Department of the Interior's Office of Surface Mining Reclamation and Enforcement's (OSMRE) efforts to implement the federally assisted coal mine subsidence insurance program. Coal mine subsidence, a gradual settling of the earth's surface above an underground mine, can damage nearby land and property. To help protect property owners from subsidence-related damage, the Congress passed legislation in 1984 authorizing OSMRE to make grants of up to $3 million to each state to help the states establish self-sustaining, state-administered insurance programs. Of the 21 eligible states, six Colorado, Indiana, Kentucky, Ohio, West Virginia, and Wyoming applied for grants. This paper reviews the efforts of these six states to develop self-sustaining insurance programs and assessed OSMRE's oversight of those efforts.

    This report provides information on surface water and groundwater management for use in the mined-land reclamation planning process in California. Mined-land reclamation, as defined by the California Surface Mining and Reclamation Act, is the combination of land treatments which prevent or minimize water degradation, air pollution, damage to aquatic or wildlife habitat, and erosion resulting from a surface mining operation. Surface water and groundwater management play an integral role in nearly every reclamation plan. Groundwater and surface water runoff (both onto and off of the site) must often be evaluated (1) to design flooding and erosion protection measures such as drainage channels, levees, culverts, or riprap; (2) to prepare and carry out a successful revegetation program; (3) to design stable final slopes; (4) to maximize potential available water for the operation and reclamation stages; (5) to prevent the discharge of contaminants from mine processes or from mined areas; and (6) to limit long-term leachate formation and movement from tailings, pit, or waste rock disposal areas. This report is a guide for mine operators, local government, planners, and plan reviewers.

    Since the implementation of the federal Surface Mining Control and Reclamation Act of 1977 (SMCRA) in May of 1978, many opportunities have been lost for the reforestation of surface mines in the eastern United States. Research has shown that excessive compaction of spoil material in the backfilling and grading process is the biggest impediment to the establishment of productive forests as a post-mining land use (Ashby, 1998, Burger et al., 1994, Graves et al., 2000). Stability of mine sites was a prominent concern among regulators and mine operators in the years immediately following the implementation of SMCRA. These concerns resulted in the highly compacted, flatly graded, and consequently unproductive spoils of the early post-SMCRA era. However, there is nothing in the regulations that requires mine sites to be overly compacted as long as stability is achieved. It has been cultural barriers and not regulatory barriers that have contributed to the failure of reforestation efforts under the federal law over the past 27 years. Efforts to change the perception that the federal law and regulations impede effective reforestation techniques and interfere with bond release must be implemented. Demonstration of techniques that lead to the successful reforestation of surface mines is one such method that can be used to change perceptions and protect the forest ecosystems that were indigenous to these areas prior to mining. The University of Kentucky initiated a large-scale reforestation effort to address regulatory and cultural impediments to forest reclamation in 2003. During the three years of this project 383,000 trees were planted on over 556 acres in different physiographic areas of Kentucky (Table 1, Figure 1). Species used for the project were similar to those that existed on the sites before mining was initiated (Table 2). A monitoring program was undertaken to evaluate growth and survival of the planted species as a function of spoil characteristics and reclamation practice. In addition, experiments were integrated within the reforestation effort to address specific questions pertaining to sequestration of carbon (C) on these sites.

    McNally, K.J.

    1987-01-01

    There has been disagreement over whether the expenditures made by the mine operator to comply with the Surface Mining Control and Reclamation Act of 1977 are characterized as capital or deductible expenses. An examination of expenditures made by mine operators during the life of a mine illustrates the dichotomy between deductible and capital expenditures in which special rules may override general capitalization rules to allow the mine operator to deduct a capital expenditure. This makes some expenditures difficult to categorize. Citing case law, the author treats expenditures for exploration and mining permits, performance bonds, and liability insurance. A new provision, section 468, allowing the current deduction for future reclamation and closing costs removed the uncertainty created by prior case law.

    The study was undertaken to determine the economic viability of surface mining to exploit the reserves. It is based on resource information already developed for NOSR 1 and conceptual designs of mining systems compatible with this resource. Environmental considerations as they relate to surface mining have been addressed qualitatively. The conclusions on economic viability were based primarily on mining costs projected from other industries using surface mining. An analysis of surface mining for the NOSR 1 resource was performed based on its particular overburden thickness, oil shale thickness, oil shale grade, and topography. This evaluation considered reclamation of the surface as part of its design and cost estimate. The capital costs for mining 25 GPT and 30 GPT shale and the operating costs for mining 25 GPT, 30 GPT, and 35 GPT shale are presented. The relationship between operating cost and stripping ratio, and the break-even stripping ratio (BESR) for surface mining to be competitive with room-and-pillar mining, are shown. Identification of potential environmental impacts shows that environmental control procedures for surface mining are more difficult to implement than those for underground mining. The following three areas are of prime concern: maintenance of air quality standards by disruption, movement, and placement of large quantities of overburden; disruption or cutting of aquifers during the mining process which affect area water supplies; and potential mineral leaching from spent shales into the aquifers. Although it is an operational benefit to place spent shale in the open pit, leaching of the spent shales and contamination of the water is detrimental. It is therefore concluded that surface mining on NOSR 1 currently is neither economically desirable nor environmentally safe. Stringent mitigation measures would have to be implemented to overcome some of the potential environmental hazards.

    Apparatus for and method are claimed for controlling the mining by a mining machine of a seam of material (e.g., coal) overlying or underlying a stratum of undesired material (e.g., clay) to reduce the quantity of undesired material mined with the desired material, the machine comprising a cutter movable up and down and adapted to cut down into a seam of coal on being lowered. The control apparatus comprises a first electrical signal constituting a slow-down signal adapted to be automatically operated to signal when the cutter has cut down into a seam of desired material generally to a predetermined depth short of the interface between the seam and the underlying stratum for slowing down the cutting rate as the cutter approaches the interface, and a second electrical signal adapted to be automatically operated subsequent to the first signal for signalling when the cutter has cut down through the seam to the interface for stopping the cutting operation, thereby to avoid mining undesired material with the desired material. Similar signalling may be provided on an upward cut to avoid cutting into the overlying stratum.

  12. Tribology of earthmoving, mining, and minerals processing

    SciTech Connect (OSTI)

    Hawk, Jeffrey A.; Wilson, Rick D.

    2001-01-01

    Earthmoving, mining, and minerals processing each involve frequent, and often severe, mechanical interactions between metals, and between metals and abrasive nonmetallic and metallic materials (i.e., mineral bearing ores). The abrasive nature of ores causes significant wear to extracting, handling, and processing equipment. Consequently, wear in earthmoving, mining, and minerals processing operations results in the removal of large amounts of material from the wear surfaces of scraping, digging, and ore processing equipment. From an energy point of view, material wear of this nature is classified as an indirect tribological loss (Imhoff et al., 1985). Additionally, a significant amount of energy is expended to overcome frictional forces in the operation of all earthmoving, mining, and minerals processing machinery (i.e., a direct tribological loss). However, in these particular processes, wear losses are more than five times those of frictional losses. In general, the amount of material lost from a particular component in these operations, before it becomes unserviceable, is far greater than that which can be tolerated in typical metal-to-metal wear situations (e.g., lubricated bearing-shaft wear couples in machinery). Consequently, much of the equipment used in earthmoving, mining, and ore processing makes use of easily replaceable or repairable, and preferably low-cost, wear components. The mechanisms by which metal-to-metal and abrasive wear occurs, and the relationships between material properties and wear behavior, are reasonably well-understood in general terms. However, the specific wear mechanisms/wear material interactions that occur during earthmoving, digging, and the processing of ore are more complex, and depend on the wear material, and on the nature of abrasive, the type of loading, and the environment. As a result of this general knowledge, reliable predictions can be made regarding the performance of particular materials under a range of in-service operating conditions. This knowledge has allowed the rational selection of wear-resistant materials for use as earthmoving, mining, and minerals processing components, and new wear-resistant materials can be designed using our knowledge of the impact and abrasion mechanisms encountered in the day-to-day operation of components used in these operations.

  13. Moving up down in the mine: Sex segregation in underground coal mining

    SciTech Connect (OSTI)

    Tallichet, S.E.

    1991-01-01

    This study employs both individualist theories of human capital and sex-role spillover and structuralist theories from the socialist feminist perspective, emphasizing the formal and informal organizational factors operating within a patriarchal capitalist society to explain job-level sex segregation among underground coal miners. Both quantitative and qualitative data on women in coal mining are used to evaluate these theories. A logistic regression analysis performed on data obtained in 1986 by the US Bureau of Mines demonstrates that while human capital variables are predictive of a miner's job rank, variation in job rank attributed to gender is even greater. For men, training and experience in mining combine to increase the probability of being in a more skilled job in a coal mine. Age and seniority are curvilinearly related to the variation in men's job rank. For women, only age accounts for their advancement such that younger, not older women who have slightly more mining experience, occupy the more skilled positions in the work place. These findings suggest that, in terms of job advancement, men enjoy a greater return on their human capital investments than women, and that factors other than those representing a miner's human capital are affecting women's positions underground more than men's.

    Zimmerman, W.; Aster, R.; Harris, J.; High, J.

    1982-11-01

    The longwall automation study presented is the first phase of a study to evaluate mining automation opportunities. The objective was to identify cost-effective, safe, and technologically sound applications of automation technology to understand coal mining. The prime automation candidates resulting from the industry experience and survey were: (1) the shearer operation, (2) shield and conveyor pan-line advance, (3) a management information system to allow improved mine logistics support, and (4) component fault isolation and diagnostics to reduce untimely maintenance delays. A system network analysis indicated that a 40% improvement in productivity was feasible if system delays associated with all of the above four areas were removed. A technology assessment and conceptual system design of each of the four automation candidate areas showed that state-of-the-art digital computer, servomechanism, and actuator technologies could be applied to automate the longwall system. The final cost benefit analysis of all of the automation areas indicated a total net national benefit (profit) of roughly $200 million to the longwall mining industry if all automation candidates were installed. This cost benefit represented an approximate order of magnitude payback on the research and development (R and D) investment. In conclusion, it is recommended that the shearer operation be automated first because it provides a large number of other sensor inputs required for face alignment (i.e., shields and conveyor). Automation of the shield and conveyor pan-line advance is suggested as the next step since both the shearer and face alignment operations contributed the greatest time delays to the overall system downtime.

    Welcome to this symposium which is part of the ongoing effort to prepare an Environmental Impact Statement (EIS) regarding mountaintop mining and valley fills. The EIS is being prepared by the U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, U.S. Office of Surface Mining, and U.S. Fish and Wildlife Service, in cooperation with the State of West Virginia. Aquatic Ecosystem Enhancement (AEE) at mountaintop mining sites is one of fourteen technical areas identified for study by the EIS Interagency Steering Committee. Three goals were identified in the AEE Work Plan: 1. Assess mining and reclamation practices to show how mining operations might be carried out in a way that minimizes adverse impacts to streams and other environmental resources and to local communities. Clarify economic and technical constraints and benefits. 2. Help citizens clarify choices by showing whether there are affordable ways to enhance existing mining, reclamation, mitigation processes and/or procedures. 3. Ide identify data needed to improve environmental evaluation and design of mining projects to protect the environment. Today’s symposium was proposed in the AEE Team Work Plans but coordinated planning for the event began September 15, 1999 when representatives from coal industry, environmental groups and government regulators met in Morgantown. The meeting participants worked with a facilitator from the Canaan Valley Institute to outline plans for the symposium. Several teams were formed to carry out the plans we outlined in the meeting.

    1993-01-01

    Abandoned underground mine openings are susceptible to collapse because of the mining methods used, the character of the overburden, and the typically large wide entries with minimal roof support. The final effect of the collapse of the underground workings is surface subsidence. To reduce the probability of subsidence, methods to backfill the mine void with various types of materials have been developed. The paper describes the available technologies for subsidence abatement and discusses their operation and application.

    Surface and underground mining operations generate seismic ground motions which are created by chemical explosions and ground failures. It may come as a surprise to some that the ground failures (coal bumps, first caves, pillar collapses, rockbursts, etc.) can send signals whose magnitudes are as strong or stronger than those from any mining blast. A verification system that includes seismic, infrasound, hydroacoustic and radionuclide sensors is being completed as part of the CTBT. The largest mine blasts and ground failures will be detected by this system and must be identified as distinct from signals generated by small nuclear explosions. Seismologists will analyze the seismic records and presumably should be able to separate them into earthquake-like and non earthquake-like categories, using a variety of so-called seismic discriminants. Non-earthquake essentially means explosion- or implosion-like. Such signals can be generated not only by mine blasts but also by a variety of ground failures. Because it is known that single-fired chemical explosions and nuclear explosion signals of the same yield give very similar seismic records, the non-earthquake signals will be of concern to the Treaty verification community. The magnitude of the mine-related events is in the range of seismicity created by smaller nuclear explosions or decoupled tests, which are of particular concern under the Treaty. It is conceivable that legitimate mining blasts or some mine-induced ground failures could occasionally be questioned. Information such as shot time, location and design parameters may be all that is necessary to resolve the event identity. In rare instances where the legitimate origin of the event could not be resolved by a consultation and clarification procedure, it might trigger on On-Site Inspection (OSI). Because there is uncertainty in the precise location of seismic event as determined by the International Monitoring System (IMS), the OSI can cover an area of up to 1,000 squared kilometers. In active mining districts this area could include several different mining operations. So, an OSI could be disruptive both to the mining community and to the US Government which must host the foreign inspection team. Accordingly, it is in the best interest of all US parties to try and eliminate the possible occurrence of false alarms. This can be achieved primarily by reducing the ambiguity of mine-induced seismic signals, so that even if these remain visible to the IMS they are clearly consistent with recognizable mining patterns.

    1985-12-09

    Accurate overburden handling cost estimation methods are essential to effective pre-mining planning for post-mining landforms and land uses. With the aim of developing such methods, the authors have been monitoring costs at a contour surface mine in Wise County, Virginia since January 1, 1984. Early in the monitoring period, the land was being returned to its Approximate Original Contour (AOC) in a manner common to the Appalachian region since implementation of the Surface Mining Control and Reclamation Act of 1977 (SMCRA). More recently, mining has been conducted under an experimental variance from the AOC provisions of SMCRA which allowed a near-level bench to be constructed across the upper surface of two mined points and an intervening filled hollow. All mining operations are being recorded by location. The cost of spoil movement is calculated for each block of coal mined between January 1, 1984, and August 1, 1985. Per cubic yard spoil handling and reclamation costs are compared by mining block. The average cost of spoil handling was $1.90 per bank cubic yard; however, these costs varied widely between blocks. The reasons for those variations included the landscape positions of the mining blocks and spoil handling practices. The average reclamation cost was $0.08 per bank cubic yard of spoil placed in the near level bench on the mined point to $0.20 for spoil placed in the hollow fill. 2 references, 4 figures.

    Congress created the Abandoned Mine Reclamation Fund (AML) in 1977 as part of the Surface Mining Control and Reclamation Act. The AML is funded by a special tax on coal mining. About one-third of AML fees will be paid by coal operators in the western states. The author examines the disbursement of AML funds under the Reagan Administration. He describes how the western state governments expected a generous portion of the AML funds for coal and non-coal reclamation, as well as community impact assistance projects in their states. Finally, the author shows how the Office of Surface Mining has largely frustrated the western expectations through its interpretation of the AML disbursement priorities.

    2001-04-19

    This paper will present a survey of the current published work and products available to do off-line data mining for computer network security information. Hundreds of megabytes of data are collected every second that are of interest to computer security professionals. This data can answer questions ranging from the proactive, ''Which machines are the attackers going to try to compromise?'' to the reactive, ''When did the intruder break into my system and how?'' Unfortunately, there's so much data that computer security professionals don't have time to sort through it all. What we need are systems that perform data mining at various levels on this corpus of data in order to ease the burden of the human analyst. Such systems typically operate on log data produced by hosts, firewalls and intrusion detection systems as such data is typically in a standard, machine readable format and usually provides information that is most relevant to the security of the system. Systems that do this type of data mining for security information fall under the classification of intrusion detection systems. It is important to point out that we are not surveying real-time intrusion detection systems. Instead, we examined what is possible when the analysis is done off-line. Doing the analysis off-line allows for a larger amount of data correlation between distant sites who transfer relevant log files periodically and may be able to take greater advantage of an archive of past logs. Such a system is not a replacement for a real-time intrusion detection system but should be used in conjunction with one. In fact, as noted previously, the logs of the real-time IDS may be one of the inputs to the data mining system. We will concentrate on the application of data mining to network connection data, as opposed to system logs or the output of real-time intrusion detection systems. We do this primarily because this data is readily obtained from firewalls or real-time intrusion detectors and it looks the same regardless of the network architecture or the systems that run on the network. This similarity greatly simplifies the data cleansing step and provides a dataset with high orthogonality between multiple sites, increasing the accuracy of the data mining operations. The decision to use connection logs instead of packet logs is discussed below. This paper will survey both the research that has been done in this area to date and publicly available products that perform such tasks.

  4. Federal oversight of alternative bond systems under SMCRA (Surface Mining Control and Reclamation Act)

    SciTech Connect (OSTI)

    Beier, A.E.; McElfish, J.M. Jr.

    1989-01-01

    The 1977 Surface Mining Control and Reclamation Act (SMCRA) requires mine operators to post reclamation bonds before mining begins. The Federal Office of Surface Mining Reclamation and Enforcement (OSMRE) has approved alternative bond systems in seven states. These systems, rather than requiring bond amounts at the full cost of reclamation, require operators to submit only a flat rate, acreage specific bond. Additional reclamation costs should be covered by a supplemental fund composed generally of permit fees, taxes, or penalties. In many cases, alternative bond systems fail to ensure that funds will be available to reclaim coal mined land in the event of operator default, as required by SMCRA. OSMRE needs to take a more active role in oversight of existing state alternative bond systems to ensure that reclamation occurs.

    This Topical Report addresses accomplishments achieved during Phase 2b of the SkyMine® Carbon Mineralization Pilot Project. The primary objectives of this project are to design, construct, and operate a system to capture CO2 from a slipstream of flue gas from a commercial coal-fired cement kiln, convert that CO2 to products having commercial value (i.e., beneficial use), show the economic viability of the CO2 capture and conversion process, and thereby advance the technology to the point of readiness for commercial scale demonstration and deployment. The overall process is carbon negative, resulting in mineralization of CO2 that would otherwise be released into the atmosphere. The project will also substantiate market opportunities for the technology by sales of chemicals into existing markets, and identify opportunities to improve technology performance and reduce costs at the commercial scale. The project is being conducted in two phases. The primary objectives of Phase 1 were to evaluate proven SkyMine® process chemistry for commercial pilot-scale operation and complete the preliminary design for the pilot plant to be built and operated in Phase 2, complete a NEPA evaluation, and develop a comprehensive carbon life cycle analysis. The objective of Phase 2b was to build the pilot plant to be operated and tested in Phase 2c.

    Economic and ecological preconditions are considered for the transition from monoproduct oil shale mining to polyproduct Estonian oil shale deposits. Underground water, limestone, and underground heat found in oil shale mines with small reserves can be operated for a long time using chambers left after oil shale extraction. The adjacent fields of the closed mines can be connected to the operations of the mines that are still working. Complex usage of natural resources of Estonian oil shale deposits is made possible owing to the unique features of its geology and technology. Oil shale seam development is carried out at shallow depths (40--70 m) in stable limestones and does not require expensive maintenance. Such natural resources as underground water, carbonate rocks, heat of rock mass, and underground chambers are opened by mining and are ready for utilization. Room-and-pillar mining does not disturb the surface, and worked oil shale and greenery waste heaps do not breach its ecology. Technical decisions and economic evaluation are presented for the complex utilization of natural resources in the boundaries of mine take of the ``Tammiku`` underground mine and the adjacent closed mine N2. Ten countries have already experienced industrial utilization of oil shale in small volumes for many years. Usually oil shale deposits are not notable for complex geology of the strata and are not deeply bedded. Thus complex utilization of quite extensive natural resources of Estonian oil shale deposits is of both scientific and practical interest.

    Sandia National Laboratories (Sandia) has a long history in developing compact, mobile, very high-speed drilling systems and this technology could be applied to increasing the rate at which boreholes are drilled during a mine accident response. The present study reviews current technical approaches, primarily based on technology developed under other programs, analyzes mine rescue specific requirements to develop a conceptual mine rescue drilling approach, and finally, proposes development of a phased mine rescue drilling system (MRDS) that accomplishes (1) development of rapid drilling MRDS equipment; (2) structuring improved web communication through the Mine Safety & Health Administration (MSHA) web site; (3) development of an improved protocol for employment of existing drilling technology in emergencies; (4) deployment of advanced technologies to complement mine rescue drilling operations during emergency events; and (5) preliminary discussion of potential future technology development of specialized MRDS equipment. This phased approach allows for rapid fielding of a basic system for improved rescue drilling, with the ability to improve the system over time at a reasonable cost.

    Surface mining is highly visible land use because it temporarily eliminates surface vegetation and can permanently change topography as with mountain-top removal and valley fill operations. It also permanently and drastically alters soil and subsurface geologic structure and disrupts surface and subsurface hydrologic regimes. The American Fisheries Society (AFS) encourages energy conservation, use of renewable resources, and recycling to minimize the need for non-renewable minerals and fuels that are obtained through mining processes. When mining occurs, it is AFS policy to encourage legislation and diligent regulation of all surface mining by local, state, province, and federal government to provide adequate protection for aquatic resources. Federal legislation provides uniformity of standards nationwide. While the Surface Mining Control and Reclamation Act has attempted to minimize environmental impacts from coal mining, similar legislation and enforcement should be encourages for other minerals. The Society encourages its members to become involved in this process by providing technical information essential for protection and continued propagation of fishery resources to policy makers so decisions are made on a scientific, rather than emotional or political basis.

    With the development of the shield support, the primary requirement for successful ground control in longwall mining is to provide stable gate road and bleeder entries. Wood cribbing has been the dominant form of secondary support. However, the cost and limited availability of timber, along with the poor performance of softwood crib supports, has forced western U.S. mines to explore the utilization of other support systems. The recent success of cable bolts has engendered much interest from western operators. Several innovative freestanding support systems have been developed recently including: (1) {open_quotes}The Can{close_quotes} support by Burrell Mining Products International, Inc., (2) Hercules and Link-N-Lock wood cribs and Propsetter by Strata Products (USA) Inc., (3) Variable Yielding Crib and Power Crib supports by Mountainland Support Systems, (4) the Confined Core Crib developed by Southern Utah Fuels Corporation; and (5) the MEGA prop by MBK Hydraulik. This paper assesses design considerations and compares the performance and application of these alternative secondary support systems.

    1986-01-01

    A mine roof bolt and a method of measuring the strain in mine roof bolts of this type are disclosed. According to the method, a flat portion on the head of the mine roof bolt is first machined. Next, a hole is drilled radially through the bolt at a predetermined distance from the bolt head. After installation of the mine roof bolt and loading, the strain of the mine roof bolt is measured by generating an ultrasonic pulse at the flat portion. The time of travel of the ultrasonic pulse reflected from the hole is measured. This time of travel is a function of the distance from the flat portion to the hole and increases as the bolt is loaded. Consequently, the time measurement is correlated to the strain in the bolt. Compensation for various factors affecting the travel time are also provided.

    The authority to regulate the coal industry at the state level, under state statute and rules, the importance of the coal industry to the state, the importance of an environmentally sound regulatory program, and the benefit of a state-managed abandoned mine reclamation program, in short the ability of the state to manage its own natural resources, make state primacy a necessity, not an option. Implementation of SMCRA cannot be measured in the myriad of oversight statistics. Effectiveness means cost-effective, timely reclamation of abandoned sites; consistent, workable rules and regulatory practices; responsive program management; and compliance which is internalized in the mine's operations.

  3. State-of-the-art techniques for backfilling abandoned mine voids

    Walker, J.S. )

    1993-01-01

    Abandoned underground mine openings are susceptible to collapse because of the mining methods used, the character of the overburden, and the typically large, wide entries with minimal roof support. The final effect of the collapse of the underground workings is surface subsidence. To reduce the probability of subsidence, methods to backfill the mine void with various types of materials have been developed. This US Bureau of Mines report describes the available technologies for subsidence abatement and discusses their operation and application. The basis of these abatement methods is the replacement of the mined material with mine waste. Backfilling of mine voids is the most common method of stabilization used to abate subsidence and protect surface structures. Hydraulic flushing and grouting, using remote methods from single or multiple boreholes, are the most often-used methods for the placement of backfill material. Other subsidence abatement techniques are available and may be more appropriate under different conditions. These other techniques include pneumatic stowing, either by in-mine or remote methods, and various point support methods that do not completely fill the mine void and are used for the protection of small areas of the land surface and surface structures. 21 refs., 14 figs.

    Two social impact assessment (SIA) studies of Central Queensland's Coppabella coal mine were undertaken in 2002-2003 and 2006-2007. As ex post studies of actual change, these provide a reference point for predictive assessments of proposed resource extraction projects at other sites, while the longitudinal element added by the second study illustrates how impacts associated with one mine may vary over time due to changing economic and social conditions. It was found that the traditional coupling of local economic vitality and community development to the life cycle of resource projects - the resource community cycle - was mediated by labour recruitment and social infrastructure policies that reduced the emphasis on localised employment and investment strategies. and by the cumulative impacts of multiple mining projects within relative proximity to each other. The resource community cycle was accelerated and local communities forced to consider ways of attracting secondary investment and/or alternative industries early in the operational life of the Coppabella mine in order to secure significant economic benefits and to guard against the erosion of social capital and the ability to cope with future downturns in the mining sector.

    Curry, P.F.

    1981-06-23

    A stabilizing arrangement for mine roof support systems of the type in which a series of support units, each including a transverse beam supported at opposite ends by extensible props, are interconnected by extensible struts in a manner to be selfadvancing by alternate retraction of support units from a roof supporting condition and extension of the struts to advance such retracted units relative to others of such units which are in an extended roof engaging condition. The connection of each prop to the beam in a given unit is pivotal to allow deflection of the beam and props of a supporting unit from a normal perpendicular relationship under load. The stabilizing means restores the props and beam to a normal perpendicular relationship for advancing movement of each support unit. The supporting units are further stabilized relative to the struts by prop supporting brackets permitting canting movement of the props from a perpendicular relationship with respect to the struts but maintaining the props in a generally upright position for unit advance.

    The crisis in American mining is discussed. The discussion focuses on the outlook for coal in the overall energy picture. Because of the Arab oil embargo of 1973, the Iranian disruption of 1979, and the tenfold increase in oil prices over the past decade, radical changes have taken place in energy supply and demand patterns. Two of the most important of these changes relate to investment. First, large investments have been made in energy-efficient plants, equipment, buildings, and vehicles. Their effect will restrain energy demand growth for the foreseeable future. Second, investments have been made in fuel-switching, from oil to coal and nuclear power. As a result the oil demand at the end of this century will be at approximately the same level as it is today. Natural gas demand is also likely to be flat. Coal demand, on the other hand, is expected to increase steadily over the long term. Recent conditions in the coal industry are reviewed, and a specific 10-year forecast is given.

    The Department of the Interior's Office of Surface Mining Reclamation and Enforcement (OSM) is spending about $65 million annually to implement regulatory program requirements of the Surface Mining Control and Reclamation Act of 1977. The act requires the regulatory authority, whether OSM or that of a state with an OSM-approved program, to charge fees to mining operators for reviewing, enforcing, and administering coal mine operating permits and authorizes that the amount of such fees can fully recover costs. The OSM and states assess certain fees, but the fees recover only a small portion of their program costs. GAO found that if OSM and states fully recovered their regulatory costs, OSM could save over $50 million a year and the impact on coal demand and production would be minimal. GAO recommends that the Secretary of the Interior collect fees that fully recover OSM's regulatory costs, phase out or substantially reduce financial assistance to states, and encourage states to fully recover their own costs.

    The overall goal of this program was to develop a pilot scale facility, and design, fabricate, and market CCBs-based lightweight blocks for mine ventilation control devices, and engineered crib elements and posts for use as artificial supports in underground mines to replace similar wooden elements. This specific project was undertaken to (1) design a pilot scale facility to develop and demonstrate commercial production techniques, and (2) provide technical and marketing support to Fly Lite, Inc to operate the pilot scale facility. Fly Lite, Inc is a joint venture company of the three industrial cooperators who were involved in research into the development of CCBs-based structural materials. The Fly-Lite pilot scale facility is located in McLeansboro, Illinois. Lightweight blocks for use in ventilation stoppings in underground mines have been successfully produced and marketed by the pilot-scale facility. To date, over 16,000 lightweight blocks (30-40 pcf) have been sold to the mining industry. Additionally, a smaller width (6-inch) full-density block was developed in August-September 2002 at the request of a mining company. An application has been submitted to Mine Safety and Health Administration for the developed block approval for use in mines. Commercialization of cribs and posts has also been accomplished. Two generations of cribs have been developed and demonstrated in the field. MSHA designated them suitable for use in mines. To date, over 2,000 crib elements have been sold to mines in Illinois. Two generations of posts were also demonstrated in the field and designated as suitable for use in mines by MSHA. Negotiations are currently underway with a mine in Illinois to market about 1,000 posts per year based on a field demonstration in their mine. It is estimated that 4-5 million tons CCBs (F-fly ash or FBC fly ash) may be utilized if the developed products can be commercially implemented in U.S. coal and non-coal mines.

    Explosive growth in geospatial data and the emergence of new spatial technologies emphasize the need for automated discovery of spatial knowledge. Spatial data mining is the process of discovering interesting and previously unknown, but potentially useful patterns from large spatial databases. The complexity of spatial data and intrinsic spatial relationships limits the usefulness of conventional data mining techniques for extracting spatial patterns. In this chapter we explore the emerging field of spatial data mining, focusing on four major topics: prediction and classification, outlier detection, co-location mining, and clustering. Spatiotemporal data mining is also briefly discussed.

The seismic signals can be generated by the use of large quantities of conventional explosives, by the collapse of underground workings, or by sudden energy release in the ground such as in rock bursts and coal bumps. These mining activities may be the cause of false alarms, but may also offer opportunities for evasive nuclear testing. So in preparing for future verification of a CTBT it becomes important to address the mining-related questions. For the United States, these are questions to be answered with respect to foreign mines. But there is a good amount of commonality in mining methods worldwide. Studies conducted at US mine sites can provide good analogs of activities that may be carried out for overseas CTBT verification, save for the expected logistical impediments.

    2005-05-09

    The work performed on this program was to develop wear resistant, tough FM composite materials with efforts focused on WC-Co based FM systems. The materials were developed for use in mining industry wear applications. Components of interest were drill bit inserts for drilling blast holes. Other component applications investigated included wear plates for a variety of equipment such as pit shovels, wear surfaces for conveyors, milling media for ball milling operations, hydrocyclone cones, grader blades and dozer teeth. Cross-cutting technologies investigated included hot metal extrusion dies, drill bits for circuit board fabrication, cutting tools for cast iron and aluminum machining. An important part of the work was identification of the standard materials used in drilling applications. A materials trade study to determine those metals and ceramics used for mining applications provided guidance for the most important materials to be investigated. WC-Co and diamond combinations were shown to have the most desirable properties. Other considerations such as fabrication technique and the ability to consolidate shifted the focus away from diamond materials and toward WC-Co. Cooperating partners such as Kennametal and Kyocera assisted with supplies, evaluations of material systems, fabricated parts and suggestions for cross-cutting technology applications for FM architectures. Kennametal provided the raw materials (WC-Co and Al-TiCN powders) for the extent of the material evaluations. Kyocera shared their research into various FM systems and provided laboratory testing of fabricated materials. Kyocera also continued research of the FM systems with the intention of developing commercial markets for a variety of applications. The continued development of FM technology by Kyocera is seen as a direct result of the cooperation established under this funding. Kyocera has a specific interest in the commercial development of the FM technology and have licensed it and have paid for the right to develop FM materials for the commercial exploitation. Field testing provided by partners Superior Rock Bit and Brady Mining and Construction provided insight into the performance of the fabricated materials under actual operational conditions. Superior Rock Bit was permitted to evaluate tri-cone roller bits in drilling applications at a mine in the Iron Range of Minnesota. Brady performed evaluation of the roof bit inserts at coal mines in medium hardness strata. The coal mine used for testing was not revealed. Additional field testing of cross-cutting technology, the extrusion of hot metals, at Extruded Metals showed the potential for additional market development. While ACR was able to perform field testing in a number of mines, tunnel boring locations and at a hot metal extrusion house under this effort, limitations of material suppliers reduced our ability to take advantage of the offered facilities at mines in the southern Arizona region. Phelps Dodge mine at Green Valley Arizona provided equipment inserts to modify for evaluation. It was a lack of available standard materials that prevented a field test to evaluate the ACR FM inserts in the application at the Green Valley mine. Efforts to develop an alternate copper electrowinning anode were pursued with additional funding from DOE. Material systems were fabricated and evaluated by research partner Hazen Research. While a drop-in replacement was not identified promising directions for future research were suggested.

  15. Electricity and technical progress: The bituminous coal mining industry, mechanization to automation

    SciTech Connect (OSTI)

    Devine, W.D. Jr.

    1987-07-01

    Development and use of electric mobile machinery facilitated the mechanization of underground bituminous coal mining and has played a lesser but important role in the growth of surface mining. Electricity has been central to the rise of mechanically integrated mining, both underground (after 1950) and on the surface (recently). Increasing labor productivity in coal mining and decreasing total energy use per ton of coal mined are associated with penetration of new electric technology through at least 1967. Productivity declined and energy intensity increased during the 1970s due in part to government regulations. Recent productivity gains stem partly from new technology that permits automation of certain mining operations. On most big electric excavating machines, a pair of large alternating current (ac) motors operate continuously at full speed. These drive direct current (dc) generators that energize dc motors, each matched to the desired power and speed range of a particular machine function. Direct-current motors provide high torque at low speeds, thus reducing the amount of gearing required; each crawler is independently propelled forward or backward by its own variable-speed dc motors. The principal advantages of electric power are that mechanical power-transmission systems - shafts, gears, etc. - are eliminated or greatly simplified. Reliability is higher, lifetime is longer, and maintenance is much simpler with electric power than with diesel power, and the spare parts inventory is considerably smaller. 100 refs., 11 figs., 12 tabs.

    The space heating in residential buildings accounts for a considerable amount of the primary energy use. Therefore, understanding the operation and performance of space heating systems becomes crucial in improving occupant comfort while reducing energy use. This study investigated the behavior of occupants adjusting their thermostat settings and heating system operations in a 62-unit affordable housing complex in Revere, Massachusetts, USA. The data mining methods, including clustering approach and decision trees, were used to ascertain occupant behavior patterns. Data tabulating ON/OFF space heating states was assessed, to provide a better understanding of the intermittent operation of space heating systems in terms of system cycling frequency and the duration of each operation. The decision tree was used to verify the link between room temperature settings, house and heating system characteristics and the heating energy use. The results suggest that the majority of apartments show fairly constant room temperature profiles with limited variations during a day or between weekday and weekend. Data clustering results revealed six typical patterns of room temperature profiles during the heating season. Space heating systems cycled more frequently than anticipated due to a tight range of room thermostat settings and potentially oversized heating capacities. In conclusion, from this study affirm data mining techniques are an effective method to analyze large datasets and extract hidden patterns to inform design and improve operations.

  1. Development of mine explosion ground truth smart sensors

    Taylor, Steven R.; Harben, Phillip E.; Jarpe, Steve; Harris, David B.

    2015-09-14

    Accurate seismo-acoustic source location is one of the fundamental aspects of nuclear explosion monitoring. Critical to improved location is the compilation of ground truth data sets for which origin time and location are accurately known. Substantial effort by the National Laboratories and other seismic monitoring groups have been undertaken to acquire and develop ground truth catalogs that form the basis of location efforts (e.g. Sweeney, 1998; Bergmann et al., 2009; Waldhauser and Richards, 2004). In particular, more GT1 (Ground Truth 1 km) events are required to improve three-dimensional velocity models that are currently under development. Mine seismicity can form the basis of accurate ground truth datasets. Although the location of mining explosions can often be accurately determined using array methods (e.g. Harris, 1991) and from overhead observations (e.g. MacCarthy et al., 2008), accurate origin time estimation can be difficult. Occasionally, mine operators will share shot time, location, explosion size and even shot configuration, but this is rarely done, especially in foreign countries. Additionally, shot times provided by mine operators are often inaccurate. An inexpensive, ground truth event detector that could be mailed to a contact, placed in close proximity (< 5 km) to mining regions or earthquake aftershock regions that automatically transmits back ground-truth parameters, would greatly aid in development of ground truth datasets that could be used to improve nuclear explosion monitoring capabilities. We are developing an inexpensive, compact, lightweight smart sensor unit (or units) that could be used in the development of ground truth datasets for the purpose of improving nuclear explosion monitoring capabilities. The units must be easy to deploy, be able to operate autonomously for a significant period of time (> 6 months) and inexpensive enough to be discarded after useful operations have expired (although this may not be part of our business plan). Key parameters to be automatically determined are event origin time (within 0.1 sec), location (within 1 km) and size (within 0.3 magnitude units) without any human intervention. The key parameter ground truth information from explosions greater than magnitude 2.5 will be transmitted to a recording and transmitting site. Because we have identified a limited bandwidth, inexpensive two-way satellite communication (ORBCOMM), we have devised the concept of an accompanying Ground-Truth Processing Center that would enable calibration and ground-truth accuracy to improve over the duration of a deployment.

  2. The states and deregulation: The case of surface mining

    SciTech Connect (OSTI)

    Scicchitano, M.J.; Hedge, D.; Metz, P.

    1989-01-01

    The Surface Mining Control and Reclamation Act of 1977 (SMCRA), passed to correct the abuses of surface mining, assigned key implementation roles to the states. While the federal government originally enforced SMCRA states could operate the program themselves. Once states decided to run their own program the federal government would oversee them to insure they properly enforce the Act. This research examines the enforcement behavior of states in the 1980s. The results indicate that early in the Reagan administration eastern states enforced the SMCRA less stringently than other states. Eastern states increased their level of enforcement later in the 1980s in response to pressures for increased federal oversight from Congress, interest groups and others.

  8. Development and Demonstration of a Modeling Framework for Assessing the Efficacy of Using Mine Water for Thermoelectric Power Generation

    SciTech Connect (OSTI)

    2010-03-01

    Thermoelectric power plants use large volumes of water for condenser cooling and other plant operations. Traditionally, this water has been withdrawn from the cleanest water available in streams and rivers. However, as demand for electrical power increases it places increasing demands on freshwater resources resulting in conflicts with other off stream water users. In July 2002, NETL and the Governor of Pennsylvania called for the use of water from abandoned mines to replace our reliance on the diminishing and sometimes over allocated surface water resource. In previous studies the National Mine Land Reclamation Center (NMLRC) at West Virginia University has demonstrated that mine water has the potential to reduce the capital cost of acquiring cooling water while at the same time improving the efficiency of the cooling process due to the constant water temperatures associated with deep mine discharges. The objectives of this project were to develop and demonstrate a user-friendly computer based design aid for assessing the costs, technical and regulatory aspects and potential environmental benefits for using mine water for thermoelectric generation. The framework provides a systematic process for evaluating the hydrologic, chemical, engineering and environmental factors to be considered in using mine water as an alternative to traditional freshwater supply. A field investigation and case study was conducted for the proposed 300 MW Beech Hollow Power Plant located in Champion, Pennsylvania. The field study based on previous research conducted by NMLRC identified mine water sources sufficient to reliably supply the 2-3,000gpm water supply requirement of Beech Hollow. A water collection, transportation and treatment system was designed around this facility. Using this case study a computer based design aid applicable to large industrial water users was developed utilizing water collection and handling principals derived in the field investigation and during previous studies of mine water and power plant cooling. Visual basic software was used to create general information/evaluation modules for a range of power plant water needs that were tested/verified against the Beech Hollow project. The program allows for consideration of blending mine water as needed as well as considering potential thermal and environmental benefits that can be derived from using constant temperature mine water. Users input mine water flow, quality, distance to source, elevations to determine collection, transport and treatment system design criteria. The program also evaluates low flow volumes and sustainable yields for various sources. All modules have been integrated into a seamless user friendly computer design aid and user's manual for evaluating the capital and operating costs of mine water use. The framework will facilitate the use of mine water for thermoelectric generation, reduce demand on freshwater resources and result in environmental benefits from reduced emissions and abated mine discharges.

    SciTech Connect (OSTI)

    Henry, K.L.

    1997-06-01

    In his forward in Night Comes to the Cumberlands, former Secretary of the Interior Stewart Udall observed that Caudill`s constructive proposals for rehabilitation of the coal counties {open_quotes}will take deep concern by people in Washington and Frankfort to bring them to fruition.{close_quotes} Deep concern for the impacts that poorly regulated surface coal mining were having on the human and natural environment animated a decade-long struggle to establish national policy for surface coal mining. The result was the Surface Mining Control and Reclamation Act of 1977, P.L. 95-97 (SMCRA). Enacted to implement a national framework for regulating the environmental effects of surface coal mining, the law established a national program for controlling environmental impacts and ensuring the reclamation of lands affected by surface mining activity. From the perspective of nearly two decades, most observers would conclude that SMCRA is an example of successful policy implementation. Few national environmental laws have succeeded as well in terms of on-the-ground results: coal production has increased dramatically and industry has made significant gains in productivity while incorporating environmental and reclamation requirements in its daily operations, lowering the cost of reclamation and environmental protection. This article discusses and evaluates the SMCRA and its effect on surface coal mining. 2 tabs.

    This report summarizes the work performed under the project (3z(BStatitically significant relational data mining.(3y (BThe goal of the project was to add more statistical rigor to the fairly ad hoc area of data mining on graphs. Our goal was to develop better algorithms and better ways to evaluate algorithm quality. We concetrated on algorithms for community detection, approximate pattern matching, and graph similarity measures. Approximate pattern matching involves finding an instance of a relatively small pattern, expressed with tolerance, in a large graph of data observed with uncertainty. This report gathers the abstracts and references for the eight refereed publications that have appeared as part of this work. We then archive three pieces of research that have not yet been published. The first is theoretical and experimental evidence that a popular statistical measure for comparison of community assignments favors over-resolved communities over approximations to a ground truth. The second are statistically motivated methods for measuring the quality of an approximate match of a small pattern in a large graph. The third is a new probabilistic random graph model. Statisticians favor these models for graph analysis. The new local structure graph model overcomes some of the issues with popular models such as exponential random graph models and latent variable models.

  5. Feasibility of high recovery highwall mining equipment. Final report

    SciTech Connect (OSTI)

    1981-01-01

    Three equipment systems exhibited significant promise: the RSV Miner, a surface longwall using standard underground equipment, and the variable angle auger. Other equipment systems showing considerable merit were the surface shortwall, and the two extended depth augers. Of the three most significant systems, the RSV Miner exhibits the greatest versatility and adaptability. It may be used competently in many surface mining applications and readily adapts to geologic anomalies and changing seam heights. The machine employs steering and guidance equipment and provides the necessary capabilities for extended depth operation. Safety is good, as no men are required to work underground. However, most important is the system's recovery factor of approximately 75% to 80% of the in-situ coal reserve within reach. The surface longwall system using standard underground equipment (preferably a ranging drum shearer in conjunction with shield supports) is most suited to either a trench mining or a modified area mining application. Both applications would allow the length of the face to be held constant. Another important consideration is legal requirements for a tailgate entry, which would necessitate additional equipment for development in a modified area mining application. When compared to surface shortwall, surface longwall exhibits higher productivity, a far greater equipment selection which allows system tailoring to geologic conditions, and greater roof control due to the significantly smaller section of overburden that must be supported. Recovery should approach, and possibly exceed, 90% of the coal in-place. The variable angle auger, which is currently only a concept, fills a very real need for which no other equipment is available at this time.

    A method for recovering coal from deeply buried deposits comprising drilling a hole down into a coal seam, filling the hole with water, and periodically detonating an explosive charge at the bottom of the water-filled hole. The water transmits the explosive shock wave to the face of the coal seam, thereby fracturing and dislodging the coal. The resulting suspension of loose coal in water is then pumped to the surface where the coal is recovered and the water is recycled to the mining operation.

    1989-01-01

    Reclamation has long been recognized as an essential action necessary to mitigate the degradation of land caused by mining activities. But, it is only within the past several decades that reclamation has become an integral component of the mineral extraction process. While the Metallic Mining Reclamation Act (MMRA) was passed in 1973, Wisconsin is yet to enact comprehensive state-wide reclamation requirements for mining other than metallic minerals and the code for metallic mining has yet to establish procedures and standards for reclamation success, specifically revegetation and postmining land use. This study integrates several interdisciplinary methodologies including a history of reclamation; an inventory and status report of mined lands; a critique and comparison of existing reclamation policy with previous state and current federal reclamation policies; in-field case studies of revegetation parameters, procedures, and performance standards; and an economic analysis of reclamation technology. This study makes three major recommendations: (1) The metallic mining code should be amended to establish vegetation parameters, measuring methods, and performance standards for revegetation success similar to those contained in the federal Surface Mining Control and Reclamation Act (SMCRA); (2) The metallic mining code should be amended to resolve semantic loopholes by clearly defining the endpoints of terms such as restoration, reclamation, and rehabilitation and by utilizing the reclamation continuum as a planning tool for determining acceptable postmining land use alternatives; and (3) Mandatory statewide nonmetallic legislation should be enacted to strengthen the mineral resource management program in Wisconsin by systematically and uniformly regulating the mining and reclamation of nonmetallic minerals, the state's most important mineral resource.

    The work performed on this program was to develop wear resistant, tough FM composite materials with efforts focused on WC-Co based FM systems. The materials were developed for use in mining industry wear applications. Components of interest were drill bit inserts for drilling blast holes. Other component applications investigated included wear plates for a variety of equipment such as pit shovels, wear surfaces for conveyors, milling media for ball milling operations, hydrocyclone cones, grader blades and dozer teeth. Cross-cutting technologies investigated included hot metal extrusion dies, drill bits for circuit board fabrication, cutting tools for cast iron and aluminum machining. An important part of the work was identification of the standard materials used in drilling applications. A materials trade study to determine those metals and ceramics used for mining applications provided guidance for the most important materials to be investigated. WC-Co and diamond combinations were shown to have the most desirable properties. Other considerations such as fabrication technique and the ability to consolidate shifted the focus away from diamond materials and toward WC-Co. Cooperating partners such as Kennametal and Kyocera assisted with supplies, evaluations of material systems, fabricated parts and suggestions for cross-cutting technology applications for FM architectures. Kennametal provided the raw materials (WC-Co and Al-TiCN powders) for the extent of the material evaluations. Kyocera shared their research into various FM systems and provided laboratory testing of fabricated materials. Field testing provided by partners Superior Rock Bit and Brady Mining and Construction provided insight into the performance of the fabricated materials under actual operational conditions. Additional field testing of cross-cutting technology, the extrusion of hot metals, at Extruded Metals showed the potential for additional market development.

    An improved method of locating an underground mine fire by comparing the pattern of measured combustion product arrival times at detector locations with a real time computer-generated array of simulated patterns. A number of electronic fire detection devices are linked thru telemetry to a control station on the surface. The mine's ventilation is modeled on a digital computer using network analysis software. The time reguired to locate a fire consists of the time required to model the mines' ventilation, generate the arrival time array, scan the array, and to match measured arrival time patterns to the simulated patterns.

  14. CONCEPTUAL DESIGN FOR A RADICALLY SMALLER, HIGHLY ADAPTIVE AND APPLICATION-FLEXIBLE MINING MACHINE FOR UTILITY AND DEVELOPMENT WORK

    2004-12-20

    The aim of this research project was to develop a preliminary ''conceptual design'' for a radically smaller, highly adaptive and application-flexible underground coal mining machine, for performing non-production utility work and/or also undertake limited production mining for the recovery of reserves that would otherwise be lost. Whereas historically, mining philosophies have reflected a shift to increasing larger mechanized systems [such as the continuous miner (CM)], specific mining operations that do not benefit from the economy of the large mining equipment are often ignored or addressed with significant inefficiencies. Developing this prototype concept will create a new class of equipment that can provide opportunities to re-think the very structure of the mining system across a broad range of possibilities, not able to be met by existing machinery. The approach involved pooling the collective input from mining professionals, using a structured listing of desired inputs in the form of a questionnaire, which was used to define the range of desired design specifications. From these inputs, a conceptual specification was blended, by the author, to embody the general concurrence of mission concepts for this machine.

  20. ADVANCED UNDERGROUND GAS STORAGE CONCEPTS REFRIGERATED-MINED CAVERN STORAGE

    SciTech Connect (OSTI)

    1998-09-01

    Limited demand and high cost has prevented the construction of hard rock caverns in this country for a number of years. The storage of natural gas in mined caverns may prove technically feasible if the geology of the targeted market area is suitable; and economically feasible if the cost and convenience of service is competitive with alternative available storage methods for peak supply requirements. It is believed that mined cavern storage can provide the advantages of high delivery rates and multiple fill-withdrawal cycles in areas where salt cavern storage is not possible. In this research project, PB-KBB merged advanced mining technologies and gas refrigeration techniques to develop conceptual designs and cost estimates to demonstrate the commercialization potential of the storage of refrigerated natural gas in hard rock caverns. Five regions of the U.S.A. were studied for underground storage development and PB-KBB reviewed the literature to determine if the geology of these regions was suitable for siting hard rock storage caverns. Area gas market conditions in these regions were also studied to determine the need for such storage. Based on an analysis of many factors, a possible site was determined to be in Howard and Montgomery Counties, Maryland. The area has compatible geology and a gas industry infrastructure for the nearby market populous of Baltimore and Washington D.C.. As Gas temperature is lowered, the compressibility of the gas reaches an optimum value. The compressibility of the gas, and the resultant gas density, is a function of temperature and pressure. This relationship can be used to commercial advantage by reducing the size of a storage cavern for a given working volume of natural gas. This study looks at this relationship and and the potential for commercialization of the process in a storage application. A conceptual process design, and cavern design were developed for various operating conditions. Potential site locations were considered and a typical plant layout was developed. In addition a geomechanical review of the proposed cavern design was performed, evaluating the stability of the mine rooms and shafts, and the effects of the refrigerated gas temperatures on the stability of the cavern. Capital and operating cost estimates were also developed for the various temperature cases considered. The cost estimates developed were used to perform a comparative market analysis of this type of gas storage system to other systems that are commercially used in the region of the study.

    Results are given of the Coal Age 2008 annual Forecast Survey of 17 coal mining executives which reinforces that 2008 could be a very good year. Coal operators are planning to invest in new equipment, development and new coal mine start-ups, based on a number of demand- and supply-side fundamentals. 71% of those surveyed thought coal production in 2008 would increase from 2007 levels and US exports are expected to climb due to the weak dollar. If the tax credit on synfuels expires on 31 December 2007 production of coal synfuel will likely cease. Asked about expensive planned purchases, companies answers ranged from $80,000 for an underground scoop to $500 m for a new mine installation. However, most producers admit they will not be able to operate at full capacity. 7 figs.

    With the passage of the Surface Mining Control and Reclamation Act of 1977 (SMCRA), regulators and industry representatives expected to solve the problem of pollution of the Nation`s waterways caused by acidic discharges from coal mines. Eighteen years after the passage of SMCRA, hard issues of predicting, regulating and treating acid mine drainage remain. Acid mine drainage is most common in the coal seams of the Midwest and Appalachia: Pennsylvania, West Virginia, Maryland, Ohio, Illinois, and Tennessee. This article discusses regulation of coal mines and acid mine drainage for the long term.

  8. INTEGRATED POWER GENERATION SYSTEMS FOR COAL MINE WASTE METHANE UTILIZATION

    2005-08-01

    An integrated system to utilize the waste coal mine methane (CMM) at the Federal No. 2 Coal Mine in West Virginia was designed and built. The system includes power generation, using internal combustion engines, along with gas processing equipment to upgrade sub-quality waste methane to pipeline quality standards. The power generation has a nominal capacity of 1,200 kw and the gas processing system can treat about 1 million cubic feet per day (1 MMCFD) of gas. The gas processing is based on the Northwest Fuel Development, Inc. (NW Fuel) proprietary continuous pressure swing adsorption (CPSA) process that can remove nitrogen from CMM streams. The two major components of the integrated system are synergistic. The byproduct gas stream from the gas processing equipment can be used as fuel for the power generating equipment. In return, the power generating equipment provides the nominal power requirements of the gas processing equipment. This Phase III effort followed Phase I, which was comprised of a feasibility study for the project, and Phase II, where the final design for the commercial-scale demonstration was completed. The fact that NW Fuel is desirous of continuing to operate the equipment on a commercial basis provides the validation for having advanced the project through all of these phases. The limitation experienced by the project during Phase III was that the CMM available to operate the CPSA system on a commercial basis was not of sufficiently high quality. NW Fuel's CPSA process is limited in its applicability, requiring a relatively high quality of gas as the feed to the process. The CPSA process was demonstrated during Phase III for a limited time, during which the processing capabilities met the expected results, but the process was never capable of providing pipeline quality gas from the available low quality CMM. The NW Fuel CPSA process is a low-cost ''polishing unit'' capable of removing a few percent nitrogen. It was never intended to process CMM streams containing high levels of nitrogen, as is now the case at the Federal No.2 Mine. Even lacking the CPSA pipeline delivery demonstration, the project was successful in laying the groundwork for future commercial applications of the integrated system. This operation can still provide a guide for other coal mines which need options for utilization of their methane resources. The designed system can be used as a complete template, or individual components of the system can be segregated and utilized separately at other mines. The use of the CMM not only provides an energy fuel from an otherwise wasted resource, but it also yields an environmental benefit by reducing greenhouse gas emissions. The methane has twenty times the greenhouse effect as compared to carbon dioxide, which the combustion of the methane generates. The net greenhouse gas emission mitigation is substantial.

    Mine Safety and Health Administration (MSHA) inspectors conduct full-shift environmental noise surveys to determine the occupational noise levels to which coal miners are exposed. These noise surveys are performed to determine compliance with the noise standard promulgated under the Federal Mine Safety and Health Act of 1977. Data from over 60,000 full-shift noise surveys conducted from fiscal year 1986 through 1992 were entered into a computer data base to facilitate analysis. This paper presents the mean and standard deviation of over 60,000 full-shift noise dose measurements for various underground and surface coal mining occupations. Additionally, it compares and contrasts the levels with historical noise exposure measurements for selected coal mining occupations that were published in the 1970`s. The findings were that the percentage of miners surveyed that were subjected to noise exposures above 100%, neglecting personal hearing protectors, were 26.5% and 21.6% for surface and underground mining, respectively. Generally, the trend is that the noise exposures for selected occupations have decreased since the 1970`s.

    Water and energy production issues intersect in numerous ways. Water is produced along with oil and gas, water runs off of or accumulates in coal mines, and water is needed to operate steam electric power plants and hydropower generating facilities. However, water and energy are often not in the proper balance. For example, even if water is available in sufficient quantities, it may not have the physical and chemical characteristics suitable for energy or other uses. This report provides preliminary information about an opportunity to reuse an overabundant water source--ground water accumulated in underground coal mines--for cooling and process water in electric generating facilities. The report was funded by the U.S. Department of Energy's (DOE's) National Energy Technology Laboratory (NETL), which has implemented a water/energy research program (Feeley and Ramezan 2003). Among the topics studied under that program is the availability and use of ''non-traditional sources'' of water for use at power plants. This report supports NETL's water/energy research program.

    The Resource Description Framework (RDF) and SPARQL Protocol and RDF Query Language (SPARQL) were introduced about a decade ago to enable flexible schema-free data interchange on the Semantic Web. Today, data scientists use the framework as a scalable graph representation for integrating, querying, exploring and analyzing data sets hosted at different sources. With increasing adoption, the need for graph mining capabilities for the Semantic Web has emerged. We address that need through implementation of three popular iterative Graph Mining algorithms (Triangle count, Connected component analysis, and PageRank). We implement these algorithms as SPARQL queries, wrapped within Python scripts. We evaluate the performance of our implementation on 6 real world data sets and show graph mining algorithms (that have a linear-algebra formulation) can indeed be unleashed on data represented as RDF graphs using the SPARQL query interface.

    This paper provides the life story of Canada's original radium/uranium mine. In addition to the history of operations, it discusses the unique and successful approach used to identify the key issues and concerns associated with the former radium, uranium and silver mining property and the activities undertaken to define the remedial actions and subsequent remedial plan. The Port Radium Mine site, situated approximately 275 km north of Yellowknife on the east shore of Great Bear Lake, Northwest Territories, was discovered in 1930 and underground mining began in 1932. The mine operated almost continuously from 1932 to 1982, initially for recovery of radium, then uranium and finally, for recovery of silver. Tailings production totaled an estimated 900,000 tons and 800,000 tons from uranium and silver processing operations respectively. In the early days of mining, Port Radium miners were exposed to radon and associated decay product levels (in Working Level Months of exposure - WLM) hundreds of times greater than modern standards. The experience of the Port Radium miners provides important contribution to understanding the risks from radon. While the uranium mine was originally decommissioned in the early 1960's, to the standards of the day, the community of Deline (formerly Fort Franklin) had concerns about residual contamination at the mine site and the potential effects arising from use of traditional lands. The Deline people were also concerned about the possible risks to Deline Dene arising from their work as ore carriers. In the late 1990's, the community of Deline brought these concerns to national attention and consequently, the Government of Canada and the community of Deline agreed to move forward in a collaborative manner to address these concerns. The approach agreed to was to establish the Canada-Deline Uranium Table (CDUT) to provide a joint process by which the people of Deline could have their concerns expressed and addressed. A great deal of work was done through the CDUT, including efforts to assess site environment and safety issues in the context of modern reclamation standards. In addition to the environmental and remediation studies, an assessment of historic exposures of Deline ore carriers to radiation and a follow-up epidemiological feasibility study were performed. SENES Consultants Limited (SENES) carried out the dose reconstruction for the Port Radium miners in the 1990's, was the environmental consultant to the CDUT from 2000 to 2005, developed the Remedial Action Plan (RAP), engineering plans and specifications for decommissioning the Port Radium mine and vicinity sites in 2005/6, supervised the remedial works in 2007 and carried out the long term post closure monitoring from 2008 to 2012. Our firsthand experience from working cooperatively with the CDUT provides insights into effective decommissioning of historic contaminated sites. (authors)

    The overall purpose of this project is to evaluate the biological and economic feasibility of restoring high-quality forests on mined land, and to measure carbon sequestration and wood production benefits that would be achieved from forest restoration procedures. In this quarterly report, we present a preliminary comparison of the carbon sequestration potential of forests growing on 14 mined sites in a seven-state region in the Midwestern and Eastern Coalfields. Carbon contents of these forests were compared to adjacent forests on non-mined land. The study was installed as a 3 x 3 factorial in a random complete block design with three replications at each location. The treatments include three forest types (white pine, hybrid poplar, mixed hardwood) and three silvicultural regimes (competition control, competition control plus tillage, competition control plus tillage plus fertilization). Each individual treatment plot is 0.5 acres. Each block of nine plots requires 4.5 acres, and the complete installation at each site requires 13.5 acres. The plots at all three locations have been installed and the plot corners marked with PVC stakes. GPS coordinates of each plot have been collected. Soil samples were collected from each plot to characterize the sites prior to treatment. Analysis of soil samples was completed and these data are being used to prepare fertilizer prescriptions. Fertilizer prescripts will be developed for each site. Fertilizer will be applied during the second quarter 2004. Data are included as appendices in this report. As part of our economic analysis of mined land reforestation, we focused on the implications of a shift in reforestation burden from the landowner to the mine operator. Results suggest that the reforestation of mined lands as part of the mining operation creates a viable and profitable forest enterprise for landowners with greater potential for carbon sequestration.

    An evaluation was made of worker exposure to hydraulic fluid used on the longwall-mining operations at Consolidated Coal Company's Humphrey Number 7 Mine, Pentress, West Virginia. Employees were complaining of headache, eye and throat irritation, congestion, and cough. A particular emulsion oil, Solcenic-3A, was used with water in the mine's hydraulic roof-support system. An analysis of the oil indicated the presence of methyl-isobutyl-carbinol (MIBC), dipropylene glycol, and paraffin hydrocarbons. Personal breathing-zone samples for MIBC were collected from all workers on the longwall mining operation during the two days of the visit. All the analysis indicated concentrations of MIBC below the limit of quantification, which was 0.6 parts per million for an 8 hour sample. These levels were well below the exposure recommendations of the Mine Safety and Health Administration. Exposure to MIBC may be occurring through skin contact with oil through hydraulic line leaks, accidents, and maintenance activity on the hydraulic machines. The report concludes that Solcenic-3A oil constituents in air did not pose a health hazard at the time of the survey.

  13. Mining Behavior Based Safety Data to Predict Safety Performance

    The Idaho National Laboratory (INL) operates a behavior based safety program called Safety Observations Achieve Results (SOAR). This peer-to-peer observation program encourages employees to perform in-field observations of each other's work practices and habits (i.e., behaviors). The underlying premise of conducting these observations is that more serious accidents are prevented from occurring because lower level at risk behaviors are identified and corrected before they can propagate into culturally accepted unsafe behaviors that result in injuries or fatalities. Although the approach increases employee involvement in safety, the premise of the program has not been subject to sufficient empirical evaluation. The INL now has a significant amount of SOAR data on these lower level at risk behaviors. This paper describes the use of data mining techniques to analyze these data to determine whether they can predict if and when a more serious accident will occur.

    Maintenance and laboratory calibrations were obtained for automatic recording methanometers for use during in-mine tests. Speecifications and quotations have been obtained for battery operated versions of the automatic recording methanometers for monitoring in the tailgate region of the longwall operation. Due to mine closings, meetings with mine operators to discuss in-mine testing and to observe the mining section to be monitored have been delayed until February 1983. Assuming a resumption of coal production, actual in-mine tests are tentatively scheduled for March, 1983. Development and testing of software modules for a general two-dimensional model has continued with good progress. The major work emphasis is on the efficient computer execution of the numerical algorithms. Preliminary simulation test runs of an isolated, unstimulated well in an isotropic, homogeneous coalbed have been made. Work has been initiated on incorporating an infinite conductivity fracture in the simulation. Graphical representation of the data generated from the two-dimensional model will be produced and verified. A request was initiated for a no-cost, six-minths extension; this request has subsequently been approved. There is no change in the contract objectives or technical approach, and the project is on target with respect to expenditures.

    The sudden collapse of man-made underground cavities have generated seismic signals as large as magnitude 5.4. Collapses are just one of the many types of mining associated seismicity including coalbumps and rockbursts which need to be identified and distinguished from potential clandestine nuclear explosions under the recently signed Comprehensive Test Ban Treaty (CTBT). Collapses, coalbumps and rockbursts are of concern for seismically monitoring a CTBT for a number of reasons. First, they can look like explosions when using some seismic discriminant measures, such M{sub s}:m{sub b}, M{sub o}: m{sub b}, regional P/S ratios and depth. Second, underground nuclear explosions themselves produce cavities that might collapse, possibly aiding in the detection of a clandestine event. Finally, because all mine-related events occur in the vicinity of underground cavities, they may come under special scrutiny because of the concern that very large, specially constructed cavities could be used to evasively decouple a clandestine test. For these reasons mine-related seismicity in both active and former mining regions have the potential to be false alarms under a CTBT. We are investigating techniques to identify collapses, either directly via waveform modeling, or indirectly by combining several seismic discriminants. We are also investigating the source mechanisms of coalbumps and collapses to better understand the performance of seismic discriminants for these events. In particular we have found similarities in point source models of some longwall coalbumps, room- and-pillar mine collapses and NTS nuclear explosion cavity collapses. In order to understand coalbumps we are analyzing events from central Utah recorded at regional distances in Utah and Nevada including at the auxiliary station ELK. Some of these have anomalous, explosion- like high frequency P/S ratios. We are combining this new study with results from previous field work done in 1995 at a Colorado long-wall coal mining operation. Similarly to longwall coal mines in Utah and elsewhere, this Colorado mine completely excavates a 3m high coal seam in 250 m wide panels leaving the material above unsupported. The roof material above the excavated seam eventually collapses resulting in seismic events.

  18. Geotechnical considerations in surface mine reclamation

    Kuhn, A.K.

    1999-07-01

    Most attention in surface mine reclamation is given to agronomic soils and revegetation, but reclamation success depends on the geotechnical characteristics of the underlying earth. If the soil and rock that underline the surface are not stable, surface treatments lack the dependable foundation needed for them to succeed. Reclamation practioners need to understand those geotechnical considerations--material properties, structure, and processes--that affect stability. properties of rock and soil are altered by mining, and those altered materials together with water and processing waste form often-complex mixtures of materials that must be stabilized in reclamation. Surface mining alters existing landforms and creates new ones such as pit walls, spoil and waste rock piles, tailings impoundments, and earthfills. those structures need to be constructed or stabilized so that they can endure and support successful reclamation. processes that affect material properties and landforms include mechanical breakage, accelerated weathering, erosion, and mass movements. Mechanical breakage and the resulting accelerated weathering combine to change material properties, usually expressed as degraded strength, that can lead to instability of landforms. Erosion, especially that related to extreme storm events, and mass movements in the form of slop failures are the most problematic processes that must be taken into account in reclaiming mined lands. These geotechnical considerations are essential in successful reclamation, and practioners who overlook them may find their work literally sliding down a slippery slope.

    The verification regime of the Comprehensive Test Ban Treaty (CTBT) provides for the possibility of On-Site Inspections (OSI`s) to resolve questions concerning suspicious events which may have been clandestine nuclear tests. Overflights by fixed-wing or rotary-wing aircraft, as part of an OSI, are permitted by the Treaty. These flights are intended to facilitate the narrowing of the inspection area, from an initial permissible 1000 km{sup 2}, and to help select the locations to deploy observers and ground-based sensors (seismic, radionuclides, . . .) Because of the substantial amount of seismicity generated by mining operations worldwide, it is expected that mine sites and mine districts would be prime candidates for OSI`S. To gain experience in this context, a number of aerial and ground-based mine site inspections have been performed in the Western U.S. by Lawrence Livermore National Laboratory since 1994. These inspections are part of a broad range of CTBT mining-related projects conducted by the U.S. Department of Energy and its National Laboratories. The various sites are described next, and inferences are made concerning CTBT OSI`S. All the mines are legitimate operations, with no implication whatsoever of any clandestine tests.

    This article examines the bonding system designed by the Surface Mining Control and Reclamation Act of 1977 (SMCRA) and some alternatives developed by several states in their regulatory programs. As well, it evaluates the systems for their potential to provide economic incentives for coal operators to engage in environmentally sound mining techniques throughout the duration of the mining activities. The first section of this article briefly reviews the SMCRA. The second section outlines the specific reclamation bonding provisions of the act. The third section analyzes economic incentives and their application to coal mining, and the fourth section more particularly evaluates the reclamation bonding provisions of the act as market based incentives. Finally, the article assesses the design of reclamation bonds and suggests modifications intended to provide greater incentives for coal producers to protect the environment. 132 references.

    Underground copper mining at the Rio Tinto mine in northern Nevada commenced in 1932 and continued intermittently for approximately forty years. Since 1975 the site has been essentially inactive. Mine operations included placement of tailings generated from ore processing in the Mill Creek drainage. In 1993, due to concerns about environmental damage to surrounding surface waters, four of the previous owners and operators of the site jointly formed the Rio Tinto Working Group (RTWG) to remediate the site in cooperation with the State of Nevada, Department of Conservation and Natural Resource and the Division of Environmental Protection (NDEP). The Rio Tinto Working Group consists of the Atlantic Richfield Company, Cleveland Cliffs Iron Company, E.I. DuPont de Nemours and Company, and Cominco American Inc., The regulatory and technical approach taken by the RTWG to achieve their objective of proactively implementing remedial measures at the site, rather than following the CERCLA process, are discussed. The steps included preparing an 18-element remedial program to be completed at the site and negotiating an Administrative Order on Consent (AOC) with the State of Nevada, which included a deferral from EPA for listing of the site on the NPL list. By entering into a cooperative relationship with the NDEP and avoiding the CERCLA process, the Rio Tinto Working Group was able to fast track site investigation and remedial designs, leading to a timely start up of remedial construction activities.

    The Project Team accomplished two tasks during the third quarter: preparation and presentation of professional papers; and development of simulation models and sub models of the hypothetical variable wall mining installation. The project team also continued its search for the suitable animation software to be adapted to the underground mining systems. Meanwhile work is progressing along the lines of updating the original open loop flow diagram that deals with the automatic control of the thrusting, advance, and rotation of the auger train which both cuts (extracts) and transports the coal across the face. The team is integrating the control systems into a deterministic mathematical equation for optimizing the mining and material flow rate in the operating system. The long range plan is to integrate the current deterministic equations in a suitable animation program with a number of adjustable and controllable parameters. This will enable coal operators and engineers to visualize how the variations can affect the safety, cost and production levels of the system.

    Present-day regulations of the Surface Mining Control and Reclamation Act were based largely on the technologies and mining methods of the late 1970`s. Thus reclamation management practices today may not fully address the landscape changes that are possible now from mountain-top removal and associated contour mining operations. This study has sought to evaluate the changes in human and natural resource systems associated with large-scale mining in the Coal River Valley region of south-central West Virginia. The Coal River Valley region was studied at a local to a landscape-scale using ground-level sampling, aerial photomaps and constructed GIS maps, starting from a site-specific-scale of natural and restored habitat types. Six watershed-drainage areas were selected for study. Three of these represented contour mining primarily and three other drainage areas encompassed mountain-top removal mining. Landscape components were characterized by overlaying slope, elevation and contour data from maps onto aerial photomaps. On-the-ground sampling was used to distinguish restoration habitat types. The site-specific measurements were obtained using transects placed across the man-made landforms (i.e., backfill, valleyfill, field, pond and drainage ditch) of the reclamation sites in each of the six watershed drainage areas. All of the measured sites had been revegetated with a seed mixture for a wildlife management plan and ranged in age from 2 to 12 years of vegetative growth at the time of the study. Percentage cover by herbaceous and woody species was determined in two-meter square quadrats placed mechanically along all transect lines to quantify the various site-specific vegetation types. Based on the site-specific evaluation, distinguishable habitats were found on each of the man-made landforms. The percentage of mountaintop removal habitats with non-native species has increased over the last decade. Percentages of total area mined in the region over thirty years were calculated, yielding a determination of changes in traditional land-uses.

    Old mine location maps (1958 vintage) indicate that the northwestern part of an undeveloped property near the town of Belleville, St. Clair County, Illinois, is situated above an abandoned and now water-filled, room-and-pillar type coal mine. The central and southeast parts of the Belleville property are shown as overlying intact (non-mined) coal. The coal unit mined at the Belleville site, the Herrin No. 6 is Pennsylvanian in age and about 2.5 m thick at a depth of around 40 m. The current owners of the Belleville property want to construct a large building on the central and southeast parts of the site, but have been concerned about the accuracy of the old mine location maps because of recent mine-related surface subsidence in areas designated on the maps as not mined. To ensure that the proposed new development is located on structurally stable ground, a grid of ten high-resolution reflection seismic lines was acquired on-site. On these reflection seismic data, mined-out areas can be visually identified and differentiated from non-mined areas. The interpretation of the reflection seismic data was constrained and validated by 15 test boreholes. These seismic and borehole data confirm that the central and southeast parts of the property have not been mined extensively. Development of the Belleville site has proceeded with confidence.

    We have completed our evaluation of candidate longwall mines available for study in the Rocky Mountain Coal Province. This report summarizes our views and evaluation of two candidate mines, the Allen Mine in Weston, Colorado, and the Hawk's Nest Mine in Somerset, Colorado. WCC visited the Allen and the Hawk's Nest Mines, and rated them in order of preference for subsidence monitoring according to criteria given in this report. Based on these evaluations and related discussions with the Technical Project Officer, the Hawk's Nest Mine appears to be the preferred mine for subsidence monitoring, because it is the only candidate mine offering two adjacent longwall panels for monitoring wherein a full subsidence profile may be obtained for at least one of the panels. Selection of this mine requires that provisions be made for monitoring 2000 ft of overburden, whereas our proposal addressed a mine with 600 ft of overburden. Changes in instrumentation which may permit the project to remain within the current budget were investigated and are discussed.

    A method and apparatus for mining of hydrocarbons from a hydrocarbon-containing clathrate such as is found on the ocean floor. The hydrocarbon containing clathrate is disaggregated from sediment by first disrupting clathrate-containing strata using continuous mining means such as a rotary tilling drum, a fluid injector, or a drill. The clathrate-rich portion of sediment thus disrupted from the sea floor strata are carried through the apparatus to regions of relative lower pressure and/or relative higher temperature where the clathrate further dissociates into component hydrocarbons and water. The hydrocarbon is recovered with the assistance of a gas that is injected and buoys the hydrocarbon containing clathrate helping it to rise to regions of lower pressure and temperature where hydrocarbon is released. The sediment separated from the hydrocarbon returns to the ocean floor.

Landforming is primary land construction that uses mining waste and applies the principles of land overlay architecture. Landforms can be layered, shaped, and configured through the use of binders and plastic sheeting to the engineering specifications necessary for the support of physical structures and passage or retention of fluids. Landforms that are terraced and south facing (in the Northern Hemisphere) are an ideal mount for sun-tracking mirror (heliostat) arrays.

    The US Department of Energy (DOE) Morgantown Energy Technology Center has implemented a comprehensive program to demonstrate the technical and economic viability of coalbed methane as an energy resource. The program is directed toward solution of technical and institutional problems impeding the recovery and use of large quantities of methane contained in the nation's minable and unminable coalbeds. Conducted in direct support of the DOE Methane Recovery from Coalbeds Project, this study analyzes the economic aspects of a horizontal borehole methane recovery system integrated as part of a longwall mine operation. It establishes relationships between methane selling price and annual mine production, methane production rate, and the methane drainage system capital investment. Results are encouraging, indicating that an annual coal production increase of approximately eight percent would offset all associated drainage costs over the range of methane production rates and capital investments considered.

Success was measured in terms of technical feasibility of the approach (i.e. % void filling), cost, environmental benefits (acid mine drainage and subsidence control) and environmental impacts (noxious ion release). Phase 1 of the project was completed in September 1995 and was concerned with the development of the grout and a series of predictive models. These models were verified through the Phase II field phase and will be further verified fin the large scale field demonstration of Phase III. The verification allows the results to be packaged in such a way that the technology can be easily adapted to different site conditions. Phase II was successfully completed with 1000 cubic yards of grout being injected into Anker Energy's Fairfax mine. The grout flowed over 600 feet from a single injection borehole. The grout achieved a compressive strength of over 1000 psi (twice the level that is needed to guarantee subsidence control). Phase III was a full scale test at Anker's eleven acre Longridge mine site. The CCB grout replaced what was an open mine void with a solid so that the groundwater tends to flow around and through the pillars rather than through the previously mined areas. The project has demonstrated that CCBs can be successfully disposed in underground mines. Additionally, the project has shown that filling an abandoned underground mine with CCBs can lead to the reduction and elimination of environmental problems associated with underground mining such as acid mine drainage and subsidence. The filling of the Longridge Mine with 43,000 cubic yards of CCB grout resulted in a 97% reduction in acid mine drainage coming from the mine.

  19. The mine management professions in the twentieth-century Scottish coal mining industry

    Perchard, A.

    2007-07-01

    This book seeks to redress the exclusion of colliery managers and other mining professionals from the history of British, and particularly Scottish, coal industries. This is accomplished by examining these groups within the most crucial period of their ascendancy in the Scottish coal mining industry, 1930-1966. This work seeks to place such persons within their context and to examine their roles, statuses and behaviours through their relationships with employees and the execution of their functions, also examining their terms and conditions of employment, the outlook of their professional associations, and that of their union. Through all this, Dr. Perchard illustrates how this growing consciousness amongst managerial employees in the industry was accompanied by an intense public discussion, within the mining professions, over their future shape, principles and occupational standards.

    SciTech Connect (OSTI)

    Sutherland, H.J.; Munson, D.E.

    1982-01-01

    Surface subsidence caused by underground mining is described through complementary influence functions. The complementary functions developed here differ from the simple functions previously used in that the surface displacement is the result of the combined contributions of the mined and unmined zones. This eliminates computational difficulties experienced with the simple functions in determining the deflections above the rib side and in the eventual application of influence functions to complex room-and-pillar configurations. Although the analysis framework presented is intended for predicting subsidence over complex mine configurations, use of the complementary functions is illustrated adequately by application to a longwall panel of the Old Ben No. 24 coal mine.

    The key issues studied focused on underground coal mining and included (1) prevention of explosions in sealed areas, (2) better emergency preparedness and response, (3) improvement of miners' ability to escape, (4) better protection of miners before and after a fire or explosion, (5) improved provision of oxygen, and (6) development and implementation of more robust post-incident communication. The U.S. Congress passed the Mine Improvement and New Emergency Response Act of 2006, which mandated new laws to address the issues. Concurrent with investigations and congressional deliberations, the National Mining Association formed the independent Mine Safety Technology and Training Commission to study the state-of-the-art relative to technology and training that could address the vulnerabilities exposed by the mine disasters. As discussed, the report outlined persistent vulnerabilities linked with significant hazards in underground coal mines, and made recommendations to provide a path for addressing them. Overall the commission report made 75 recommendations in the areas of risk-based design and management, communications technology, emergency response and mine rescue procedures, training for preparedness, and escape and protection strategies. In its deliberations, the commission importantly noted that mine safety in the U.S. needs to follow a new paradigm for ensuring mine safety and developing a culture of prevention that supports safe production at the business core. In the commission's viewpoint, the bottom line in protecting coal miners is not only adopting a culture of prevention but also systematically pursuing mitigation of significant risks. 4 refs., 2 figs.

    Since 1994, various mines in the US have cooperated with research scientists at the Los Alamos and Lawrence Livermore National Laboratories to address issues related to verification of the Comprehensive Test Ban Treaty (CTBT). The CTBT requires that no country may conduct any nuclear explosion in the future. While the CTBT is a significant step toward reducing the global nuclear danger, verifying compliance with the treat requires that the monitoring system be able to detect, locate and identify much larger numbers of smaller amplitude seismic events than had been required previously. Large mining blasts conducted world-wide will be of sufficient amplitude to trigger the monitoring system at the lower threshold. It is therefore imperative that research into the range various blasting practices employed, the relationship of yield to seismic magnitude, and identification of anomalous blasting results be performed. This paper will describe a suite of experiments funded by the Department of Energy and conducted by the Los Alamos and Lawrence Livermore National Laboratories in cooperation with the US mining industry. Observations of cast blasting, underground long wall generated coal bumps, stoping, and explosively induced collapse of room and pillar panels will be presented. Results of these dual use experiments which are of interest to the mining community will be discussed. These include (1) variation of amplitude of seismic energy at various azimuths from cast blasts, (2) identification of the extent of back failure following explosive removal of pillars, and (3) the use of single fired shots for calibration of the monitoring system. The wealth of information and discovery described in this paper is a direct result of mutual cooperation between the US Government and the US Mining Industry.

  10. Evaluation of Roof Bolting Requirements Based on In-Mine Roof Bolter Drilling

    2005-10-01

    Roof bolting is the most popular method for underground openings in the mining industry, especially in the bedded deposits such as coal. In fact, all U.S. underground coal mine entries are roof-bolted as required by law. However, roof falls still occur frequently in the roof bolted entries. The two possible reasons are: the lack of knowledge of and technology to detect the roof geological conditions in advance of mining, and lack of roof bolting design criteria for modern roof bolting systems. This research is to develop a method for predicting the roof geology and stability condition in real time during roof bolting operation. Based on this information, roof bolting design criteria for modern roof bolting systems will be developed for implementation in real time. For the prediction of roof geology and stability condition in real time, a micro processor was used and a program developed to monitor and record the drilling parameters of roof bolter. These parameters include feed pressure, feed flow (penetration rate), rotation pressure, rotation rate, vacuum pressure, oil temperature of hydraulic circuit, and signals for controlling machine. From the results of a series of laboratory and underground tests so far, feed pressure is found to be a good indicator for identifying the voids/fractures and estimating the roof rock strength. The method for determining quantitatively the location and the size of void/fracture and estimating the roof rock strength from the drilling parameters of roof bolter was developed. Also, a set of computational rules has been developed for in-mine roof using measured roof drilling parameters and implemented in MRGIS (Mine Roof Geology Information System), a software package developed to allow mine engineers to make use of the large amount of roof drilling parameters for predicting roof geology properties automatically. For the development of roof bolting criteria, finite element models were developed for tensioned and fully grouted bolting designs. Numerical simulations were performed to investigate the mechanisms of modern roof bolting systems including both the tension and fully grouted bolts. Parameters to be studied are: bolt length, bolt spacing, bolt size/strength, grout annulus, in-situ stress condition, overburden depth, and roof geology (massive strata, fractured, and laminated or thinly-bedded). Based on the analysis of the mechanisms of both bolting systems and failure modes of the bolted strata, roof bolting design criteria and programs for modern roof bolting systems were developed. These criterion and/or programs were combined with the MRGIS for use in conjunction with roof bolt installation.

    Roof bolting is the most popular method for underground openings in the mining industry, especially in the bedded deposits such as coal, potash, salt etc. In fact, all U.S. underground coal mine entries are roof-bolted as required by law. However, roof falls still occur frequently in the roof bolted entries. The two possible reasons are: the lack of knowledge of and technology to detect the roof geological conditions in advance of mining, and lack of roof bolting design criteria for modern roof bolting systems. This research is to develop a method for predicting the roof geology and stability condition in real time during roof bolting operation. Based on such information, roof bolting design criteria for modern roof bolting systems will be developed for implementation in real time. The retrofitting works for a dedicated roof bolter for this research has been completed. The laboratory tests performed using this machine on simulated roof blocks have been conducted. The analysis performed on the testing data showed promising signs to detect the rock interface, fractures, as well as the rock types. The other tasks were progressing as planned.

    2012-06-01

    Identifying software vulnerabilities is becoming more important as critical and sensitive systems increasingly rely on complex software systems. It has been suggested in previous work that some bugs are only identified as vulnerabilities long after the bug has been made public. These vulnerabilities are known as hidden impact vulnerabilities. This paper discusses the feasibility and necessity to mine common publicly available bug databases for vulnerabilities that are yet to be identified. We present bug database analysis of two well known and frequently used software packages, namely Linux kernel and MySQL. It is shown that for both Linux and MySQL, a significant portion of vulnerabilities that were discovered for the time period from January 2006 to April 2011 were hidden impact vulnerabilities. It is also shown that the percentage of hidden impact vulnerabilities has increased in the last two years, for both software packages. We then propose an improved hidden impact vulnerability identification methodology based on text mining bug databases, and conclude by discussing a few potential problems faced by such a classifier.

    A bioreactor for reacting an aqueous heavy metal and sulfate containing mine drainage solution with sulfate reducing bacteria to produce heavy metal sulfides and reduce the sulfuric acid content of the solution. The reactor is an elongated, horizontal trough defining an inlet section and a reaction section. An inlet manifold adjacent the inlet section distributes aqueous mine drainage solution into the inlet section for flow through the inlet section and reaction section. A sulfate reducing bacteria and bacteria nutrient composition in the inlet section provides sulfate reducing bacteria that with the sulfuric acid and heavy metals in the solution to form solid metal sulfides. The sulfate reducing bacteria and bacteria nutrient composition is retained in the cells of a honeycomb structure formed of cellular honeycomb panels mounted in the reactor inlet section. The honeycomb panels extend upwardly in the inlet section at an acute angle with respect to the horizontal. The cells defined in each panel are thereby offset with respect to the honeycomb cells in each adjacent panel in order to define a tortuous path for the flow of the aqueous solution.

    1985-07-01

    Concern over mining-related subsidence is inhibiting the development of surface land uses in previously mined areas and is constraining the recovery of coal resources in areas with established land uses that might be impacted by subsequent subsidence. The determination of subsidence vulnerability of mined-out areas (especially abandoned mine areas) can be a useful tool in the design and location of surface structures. A model has been developed for assessing subsidence vulnerability in shallow room-and-pillar mines based on the flexural rigidity and strength characteristics of the overlying strata. The model does not predict the subsidence profile or when the subsidence will occur. It only predicts those areas that are likely to subside. This paper briefly describes the model and its testing.

    The York Canyon mine evaluation has been completed and sent out for review and comment. Several mining companies including Consol, Plateau, and Emery have been contacted regarding future testing. York Canyon has also expressed interest in continuing the investigation. Further analysis of the York Canyon data has indicated several unknowns which should be identified during the next evaluation. Among them are the centrality of sensor position with respect to both cross and along the face axes. Also, it is felt that separation of other spatially related dust sources (e.g., conveyor, crusher, gob consolidation and air patterns) is important. In order to conduct the new headgate cutout tests, the existing longwall gallery was modified. A fan and duct work were added to simulate gob leakage in line with the headgate entry. Tracer gas concentration profiles, smoke tracers, and air velocity measurements have been taken. Primary airflows of 12,000 cfm with gob leakage of 5000 cfm and primary airflow of 7000 cfm without gob leakage gave similar results. The airflow along the face was the prime factor and not the primary airflow. The wing curtain did not have a significant impact on the tailgate operator and drum zones. It did have a marginal effect at the headgate operator zone. The use of shearer clearer spray system did have a large impact on improving the tracer gas pattern along the face, but at the same time adversely deteriorated the tailgate operator zone in two ways: higher tracer gas concentrations and water mist.

    The Intermountain Center for Mining Research and Development (ICMRD) was established with the Idaho National Laboratory (INL) as the cornerstone, and with regional universities, mining schools, and the Western mining industry as full members. In aggregate, the members provide the strong mining research and development capabilities and knowledge that are essential to the success of such a research center. The ICMRD is an organization that identifies technical needs, partially funds, and provides project management for research projects. The ICMRD will primarily serve the nine Intermountain States, but will not restrict other regions, research organizations, or academic institutions from membership. The ICMRD's nine primary states are: Idaho, Montana, Wyoming, Utah, Colorado, Nevada, Arizona, Alaska, and New Mexico. The business and project management functions of the ICMRD will be located at INL. Research projects may be performed by INL, one of the member research organizations, academic institutions, mining companies/suppliers, or preferably, by a partnership of several of these institutions. Teaming among members will be essential in providing quality R&D. The ICMRD will accomplish its research goals by creating partnerships between the research organizations, federal and state agencies, and the mining industry.

    The proposed establishment of the US Navy Mine Warfare Center of Excellence (MWCE) in the Corpus Christi Bay Area, Texas, involved the collocation of the Navy`s Mine Warfare and Mine Counter Measures assets in proximity to each other at Naval Station (NAVSTA) Ingleside and Naval Air Station (NAS) Corpus Christi, Texas. Collocation of these Navy forces would provide significant advantages in meeting mission and operational requirements. This action would improve the operational training and readiness of the forces. In addition to new construction or modifications at NAVSTA Ingleside, NAS Corpus Christi, and off-base; the establishment of offshore training and operating areas was required. When the project was first proposed in 1993, considerable concern was expressed by environmental interests, shrimpers, and state and federal resource agencies regarding the impact of the proposed training activities within Gulf waters. The Navy and Turner Collie and Braden, Inc., under contract to the Navy, conducted several technical studies and extensive coordination with concerned interests during the environmental impact statement process to identify and document the potential intensity, magnitude, and duration of impact from each proposed training activity.

    Displacement and stress changes in cemented backfill and ore pillars at the Buick Mine, near Boss, MO, were monitored by engineers from the US Bureau of Mines and The Doe Run Co., St. Louis, MO. A test area in this room-and-pillar mine was backfilled to provide support when remnant ore pillars were mined. Objectives of this research were to evaluate the effect of backfill on mine stability, observe backfill conditions during pillar removal, and calibrate a numerical model to be used to design other areas of the mine. Relative vertical displacements in the backfill were measured with embedment strain gauges and vertical extensometers. Other types of instruments used were earth pressure cells (to identify loading trends in the backfill), borehole extensometers (to measure relative displacement changes in the mine roof and support pillars), and biaxial stressmeters (to measure stress changes in several support pillars and abutments). Two- and three-dimensional numeric codes were used to model the study area. With information from these codes and the installed instruments, two failed pillars were identified and rock mass properties were estimated.

    1985-12-01

    The Illinois Abandoned Mined Lands Reclamation Council (AMLRC), created in 1975, is responsible for the abatement of hazardous and environmental problems associated with pre-law abandoned coal mines throughout the State. The availability of federal funds for reclamation, through passage of the Surface Mining Control and Reclamation Act of 1977 (SMCRA), greatly expanded the program. With funds provided through early cooperative agreements and current annual grants from the federal Office of Surface Mining (OSM), the State has reclaimed, or is currently reclaiming, 182 mine sites and has assisted OSM in the abatement of 67 emergency situations. This paper reviews the progress made by the AMLRC in dealing with the State's abandoned mine problems. Specifically, the numbers and types of problem sites reclaimed annually, their costs, and reclamation methods are identified. Progress of the program relative to the entire State's abandoned mine problems is reviewed. The effects of other reclamation factors, such as natural revegetation, remaining privately-funded reclamation, and secondary carbon recovery, on the overall scope of the State's program are also examined. General comments are made concerning grant preparation, State-OSM cooperation and AML-Inventory control. Selected reclamation projects and techniques are also discussed. 11 references, 3 tables.

    At the request of the Department of Energy and Westinghouse Hanford Company, the Bureau of Mines has investigated the flammability of mixtures of hydrogen, ammonia, nitrous oxide, and air. The tests were performed in a spherical chamber under quiescent and turbulent conditions. This paper describes combustion calculations using the GASFLOW code and compares the calculated pressure ratios with experiments mentioned above. GASFLOW is a finite-volume computer code that solves the transient, three-dimensional, compressible fluid, Navier-Stokes equations with multiple species coupled with finite-rate chemical kinetics. The computational results show good agreement with the experimental data and confirm GASFLOW to be a valuable tool for evaluating the above combustion process.

    A data mining system uncovers patterns, associations, anomalies and other statistically significant structures in data. Data files are read and displayed. Objects in the data files are identified. Relevant features for the objects are extracted. Patterns among the objects are recognized based upon the features. Data from the Faint Images of the Radio Sky at Twenty Centimeters (FIRST) sky survey was used to search for bent doubles. This test was conducted on data from the Very Large Array in New Mexico which seeks to locate a special type of quasar (radio-emitting stellar object) called bent doubles. The FIRST survey has generated more than 32,000 images of the sky to date. Each image is 7.1 megabytes, yielding more than 100 gigabytes of image data in the entire data set.

    The public reclamation cost of reclaiming all of Pennsylvania`s abandoned mine lands is estimated at $15 billion. Drainage from abandoned mines poses another $5 billion water pollution clean-up problem. Although it is unlikely that public reclamation alone could ever tackle these problems, much can be done to alleviate the nuisances through the remining of previously mined areas to recover remaining reserves, restore the land and improve water quality in the same process. Remining of priority areas is encouraged through a new Pennsylvania policy which provides incentives to mining companies. One incentive, initiated under Pennsylvania`s comprehensive mine reclamation strategy, is to identify and geologically map reminable coal resources in selected watersheds, and then to expedite mine permitting in these watersheds. At present, two such priority watersheds, Little Toby Creek in Elk County and Tangascootak Creek in Clinton County, are the focus of geologic map compilation based on recent quadrangle mapping, or new, directed, geologic mapping, including new research core drilling to establish the geologic stratigraphic framework. In order to maximize environmental benefits the comprehensive mine reclamation strategy identifies watersheds which are affected by acid mine drainage (AMD), but that are reasonably capable of restoration, if sufficient coal reserves remain. Pennsylvania`s geochemical quality database of rock overburden, in combination with detailed coal resource mapping by the Pennsylvania Geological Survey, and the cooperation of coal companies and leaseholders, is being used by the Department of Environmental Protection (DEP) to identify and design remining projects which will not only allow the recovery of coal resources, but will also improve the water quality through a variety of innovative mining techniques.

    This controversial book examines environmental regulation of coal mining in the United States over the 1979-1989 period. The Surface Mining Control and Reclamation Act of 1977 (SMCRA) established federal regulation of the environmental effects of coal mining. The permanent regulatory program implementing SMCRA was initiated in 1979. This book looks at the first ten years of SMCRA, seeking to draw lessons from experience that will improve regulation, so that the objectives of the law may be achieved in SMCRA`s second decade.

    1995-12-31

    Acid mine drainage is a major problem related to coal mining which, if unabated, can severely damage the aquatic environment. Damage resulting from acid mine drainage was first addressed by common law and riparian principles. As societal laws changed, common law principles alone could not effectively control this problem. Preventing and controlling pollution including acid mine drainage are important goals of the Surface Mining Control Reclamation Act (SMCRA) and the Clean Water Act (CWA). This article examines how common law, SMCRA, and the CWA address the acid mine drainage issue independently, and how improvements in the control of acid mine drainage can be achieved.

    Work on Phase I of the Contract program is essentially complete and was reported in the Phase I Technical Report which has been reviewed and accepted by the Contract Technical Project Officer. Phase I work included a survey of relevant technical literature and development, demonstration and documentation of a computer model, MINE1D, for flow of methane and water in coal strata for geometries corresponding to an advancing mine face and to a mine pillar. The Phase I models are one-dimensional in the space variable but describe time-dependent (nonsteady) phenomena and include gas sorption phenomena. Some revisions have been made to input/output sections of MINE1D and the documentation has been expanded. These modifications will be reported in the next Quarterly Technical Report. Preliminary test scenarios have been formulated and reviewed with the Contract Technical Project Officer for measurement of emissions during room-and-pillar and longwall mining operations. These preliminary scenarios are described in this report. A mathematical model has been developed to describe the increased stresses on the coal seam near mine openings. The model is based on an approximate elastic/plastic treatment of the coal seam and an elastic treatment of surrounding strata. In this model, elastic compaction of the coal seam decreases porosity and permeability, whereas plastic deformation increases the porosity of the natural fracture network and thereby increases the permeability. The model takes into account the effect of changes in pore fluid pressure (in the natural fracture network of the coal seam) on the deformation of the coal seam. This model is described in this report, and will be programmed for inclusion in revised versions of MINE1D and for use in the two-dimensional computer models now under development. 8 figures.

    2000-06-12

    A solution mining facility at the Eddy Potash Mine, Eddy County, New Mexico has been proposed that will utilize salinity gradient solar pond (SGSP) technology to supply industrial process thermal energy. The process will include underground dissolution of potassium chloride (KCl) from pillars and other reserves remaining after completion of primary room and pillar mining using recirculating solutions heated in the SGSP. Production of KCl will involve cold crystallization followed by a cooling pond stage, with the spent brine being recirculated in a closed loop back to the SGSP for reheating. This research uses SGSP as a renewable, clean energy source to optimize the entire mining process, minimize environmental wastes, provide a safe, more economical extraction process and reduce the need for conventional processing by crushing, grinding and flotation. The applications of SGSP technology will not only save energy in the extraction and beneficiation processes, but also will produce excess energy available for power generation, desalination, and auxiliary structure heating.

    Land, water and energy use are key measures of the sustainability of uranium production into the future. As the most attractive, accessible deposits are mined out, future discoveries may prove to be significantly, perhaps unsustainably, more intensive consumers of environmental resources. A number of previous attempts have been made to provide empirical relationships connecting these environmental impact metrics to process variables such as stripping ratio and ore grade. These earlier attempts were often constrained by a lack of real world data and perform poorly when compared against data from modern operations. This paper conditions new empirical models of energy, water and land use in uranium mining, milling, and refining on contemporary data reported by operating mines. It shows that, at present, direct energy use from uranium production represents less than 1% of the electrical energy produced by the once-through fuel cycle. Projections of future energy intensity from uranium production are also possible by coupling the empirical models with estimates of uranium crustal abundance, characteristics of new discoveries, and demand. The projections show that even for the most pessimistic of scenarios considered, by 2100, the direct energy use from uranium production represents less than 3% of the electrical energy produced by the contemporary once-through fuel cycle.

    This report defines the state of the art (circa 1978) in removing thin coal seams associated with vastly thicker seams found in the surface coal mines of the western United States. New techniques are evaluated and an innovative method and machine is proposed. Western states resource recovery regulations are addressed and representative mining operations are examined. Thin seam recovery is investigated through its effect on (1) overburden removal, (2) conventional seam extraction methods, and (3) innovative techniques. Equations and graphs are used to accommodate the variable stratigraphic positions in the mining sequence on which thin seams occur. Industrial concern and agency regulations provided the impetus for this study of total resource recovery. The results are a compendium of thin seam removal methods and costs. The work explains how the mining industry recovers thin coal seams in western surface mines where extremely thick seams naturally hold the most attention. It explains what new developments imply and where to look for new improvements and their probable adaptability.

    1984-12-01

    Subsidence research by the US Bureau of Mines has identified and documented the occurrence of landslides over a longwall mining area in the Dunkard basin. Mining by longwall methods has been observed or produce a gradual surface subsidence profile of up to 60% of the thickness of the mined coal bed. The gradual subsidence of panels averaging 600 x 5000 ft (180 x 1525 m) can cause reactivation of older landslide deposits by decreasing the support to the landslide toe area. Examination of surficial features over a longwall mining area comprised of nine panels has led to the identification of several reactivated landslides. The two largest landslides occurred above a thin sandstone member with several associated springs. The largest landslides ranged from 100 to 300 ft (30 to 90 m) in length and from 100 to 200 ft (30 to 60 m) in width. Maximum scarp-slope displacements were approximately 7 ft (2 m). Less significant mass wasting was also observed over the longwall panels. Identification of landslides was accomplished through examination of premining aerial photographs and geologic field investigation. Characterization of reactivated zones was achieved through evaluation of current aerial 2-ft (0.6-m) surface contour map and field surveys. Recognition of problem areas will make civic and mining personnel aware of the landslide potential so that damage in such areas can be minimized.

    In recent years, it has become much more difficult to deal with the adhesion and freezing of moist overburden or soil during mining and transport operations due to the increase in the volume of the various materials being mined and transported - coal, ore, fluxes, structural materials, etc. The most productive and effective methods to deal with the sticking and freezing of soil and rock are gas dynamic methods. These methods employ high-speed jets of hot gases from jet engines and can be 15-30 times more productive than mechanical methods and machinery. Proceeding on the basis of calculations, completed studies, and field tests, the Gortekhtrans Department of Research Institute for Problems of the Kursk Magnetic Anomaly (NIIKMA) has developed several highly efficient units that employ this technology.

    Available in abstract form only. Full text of publication follows: Several of the Central Asian countries of the former Soviet Union were involved in the uranium mining and milling industry from about 1945 for varying periods until the break up of the Soviet Union in 1991 and beyond. Some facilities are still producing in Uzbekistan and Kazakhstan. However, before the break up, many facilities had been abandoned and in only a few cases had any remediation been undertaken. Since 1991 the newly independent states of the region have been seeking assistance for the remediation of the multitude of tailings piles, waste rock stockpiles and abandoned, and often semi dismantled, production facilities that may be found throughout the region. Many of these sites are close to settlements that were established as service towns for the mines. Most towns still have populations, although the mining industry has departed. In some instances there are cases of pollution and contamination and in many locations there is a significant level of public concern. The IAEA has been undertaking a number of Technical Cooperation (TC) projects throughout the region for some time to strengthen the institutions in the relevant states and assist them to establish monitoring and surveillance programs as an integral part of the long term remediation process. The IAEA is liaising with other agencies and donors who are also working on these problems to optimise the remediation effort. The paper describes the objectives and operation of the main TC regional program, liaison efforts with other agencies, the achievements so far and the long term issues for remediation of these legacies of the 'cold war' era.

    1984-12-01

    A method for describing and evaluating coal mine wastes evolved in 1982 from studies at more than 100 historic longwall mine sites conducted by the Illinois State Geological Survey and partially funded by the Illinois Abandoned Mined Lands Reclamation Council (IAMLRC). The primary purpose was to locate and identify different types of waste materials at these sites and to evaluate them for future reclamation. The method which involves geologic characterization, sampling, standard analyses, and evaluation tests, can be used to determine the potential of a mine waste deposit for secondary recovery of coal. It yields data relating to three factors involved in secondary recovery: quality (ash content, heating value), quantity (recoverable tonnages), and the net effect of the recovery operation (product value relative to operations costs; social and environmental assets relative to liabilities). The longwall study did not directly address the question of recoverable tonnages of coal but provided information that can be used to make this evaluation, minimize the amount of drilling required for accurate forecasts of profitability, and measure the economic and environmental benefits of secondary recovery steps in a reclamation plan.

    The Nuclear Waste Policy Act of 1982 assigned to the Department of Energy's (DOE) Office of Civilian Waste Management the responsibility for disposing of high-level waste and spent fuel. A significant part of that responsibility involves transporting nuclear waste materials within the federal waste management system; that is, from the waste generator to the repository. The lead responsibility for transportation operations has been assigned to Oak Ridge Operations, with Oak Ridge National Laboratory (ORNL) providing technical support through the Transportation Operations Support Task Group. One of the ORNL support activities involves assessing what facilities, equipment and services are required to assure that an acceptable, cost-effective and safe transportation operations system can be designed, operated and maintained.

    The results of a field investigation on the groundwater-hydrologic effect of mining-induced earthquakes are presented in this report. The investigation was conducted at the Lucky Friday Mine, a silver-lead-zinc mine in the Coeur d`Alene Mining District of Idaho. The groundwater pressure in sections of three fracture zones beneath the water table was monitored over a 24-mo period. The fracture zones were accessed through a 360-m-long inclined borehole, drilled from the 5,700 level station of the mine. The magnitude, source location, and associated ground motions of mining-induced seismic events were also monitored during the same period, using an existing seismic instrumentation network for the mine, augmented with additional instruments installed specifically for the project by the center for Nuclear Waste Regulatory Analyses (CNWRA). More than 50 seismic events of Richter magnitude 1.0 or larger occurred during the monitoring period. Several of these events caused the groundwater pressure to increase, whereas a few caused it to decrease. Generally, the groundwater pressure increased as the magnitude of seismic event increased; for an event of a given magnitude, the groundwater pressure increased by a smaller amount as the distance of the observation point from the source of the event increased. The data was examined using regression analysis. Based on these results, it is suggested that the effect of earthquakes on groundwater flow may be better understood through mechanistic modeling. The mechanical processes and material behavior that would need to be incorporated in such a model are examined. They include a description of the effect of stress change on the permeability and water storage capacity of a fracture rock mass; transient fluid flow; and the generation and transmission of seismic waves through the rock mass.

  3. The Kelastic variable wall mining machine. Interim final report

    SciTech Connect (OSTI)

    1995-11-12

    This machine cuts coal along a longwall face extending up to 500 feet by a rotating auger with bits. The machine also transports the coal that is cut acting as screw conveyor. By virtue of an integral shroud comprising part of the conveyor the machine is also amenable to a separation of the zones where men work from air being contaminated by dust and methane gas by the cutting action. Beginning as single intake air courses, the air separates at the working section where one split provides fresh air to the Occupied Zone (OZ) for human needs and the other split purges and carries away dust and methane from face fragmentation in the Cutting Zone (CZ). The attractiveness of the Variable Wall Mining Machine is that it addresses the limitations of current longwall mining equipment: it can consistently out-produce continuous mining machines and most longwall shearing machines. It also is amenable to configuring an environment, the dual-duct system, where the air for human breathing is separated from dust-laden ventilating air with methane mixtures. The objective of the research was to perform a mathematical and experimental study of the interrelationships of the components of the system so that a computer model could demonstrate the workings of the system in an animation program. The analysis resulted in the compilation of the parameters for three different configurations of a dual aircourse system of ventilating underground mines. In addressing the goal of an inherently safe mining system the dual-duct adaptation to the Variable Wall Mining Machine appears to offer the path to solution. The respirable dust problem is solvable; the explosive dust problem is nearly solvable; and the explosive methane problem can be greatly reduced. If installed in a highly gassy mine, the dual duct models would also be considerably less costly.

    1995-11-01

    The exhaustion of fuel-energy resources became an evident problem of the European continent in the 1960s. Careful utilization of their own reserves of coal, oil, and gas (Germany, France, Spain) and assigned shares of imports of these resources make up the strategy of economic development of the European countries. The expansion of oil shale utilization is the most topical problem. The experience of mining oil shale deposits in Estonia and Russia, in terms of the practice and the economic results, is reviewed in this article. The room-and-pillar method of underground mining and the open-cut technology of clearing the ground ensure the fertility of a soil. The economics of underground and open pit oil shale mines is analyzed in terms of natural, organizational, and technical factors. These analyses are used in the planning and management of oil shale mining enterprises. The perspectives of the oil shale mining industry of Estonia and the economic expediency of multiproduction are examined. Recommendations and guidelines for future industrial utilization of oil shale are given in the summary.

    Subsidence is the sinking of land surface, commonly resulting from underground mining. In Illinois, property damage has been sufficiently severe that a state law was enacted to provide subsidence insurance for homeowners. This publication has been prepared for homeowners in Illinois: (1) to inform them whether they live in subsidence-prone areas, (2) to aid them in understanding some frequently encountered effects of mine subsidence as well as problems sometimes mistaken for mine subsidence, and (3) to suggest further sources of information. Although the new subsidence insurance program for homeowners in mining areas prompted the writing of this report, we do not attempt to explain the details of the insurance program. Our purpose is to explain the causes and the nature of subsidence and discuss ways to minimize damage caused by subsidence. About 750,000 acres of Illinois land have been undermined for coal, and many homeowners are concerned about the effects underground mining may d at nine areas alalitative methods are presented. Chapter Five presents conclusions and suggestions for future research.

  17. Modeling Spatial Dependencies and Semantic Concepts in Data Mining

    SciTech Connect (OSTI)

    Vatsavai, Raju

    2012-01-01

    Data mining is the process of discovering new patterns and relationships in large datasets. However, several studies have shown that general data mining techniques often fail to extract meaningful patterns and relationships from the spatial data owing to the violation of fundamental geospatial principles. In this tutorial, we introduce basic principles behind explicit modeling of spatial and semantic concepts in data mining. In particular, we focus on modeling these concepts in the widely used classification, clustering, and prediction algorithms. Classification is the process of learning a structure or model (from user given inputs) and applying the known model to the new data. Clustering is the process of discovering groups and structures in the data that are ``similar,'' without applying any known structures in the data. Prediction is the process of finding a function that models (explains) the data with least error. One common assumption among all these methods is that the data is independent and identically distributed. Such assumptions do not hold well in spatial data, where spatial dependency and spatial heterogeneity are a norm. In addition, spatial semantics are often ignored by the data mining algorithms. In this tutorial we cover recent advances in explicitly modeling of spatial dependencies and semantic concepts in data mining.

    2009-04-15

    The goal of our research was to assess the impact of post-mining land subsidence, caused due to underground coal mining operations, on fine root biomass and root tips count; plant available nutrient status, microbial biomass N (MBN) and N-mineralization rates of a Southern tropical dry deciduous forest of Singareni Coalfields of India. The changes were quantified in all the three (rainy, winter and summer) seasons, in slope and depression microsites of the subsided land and an adjacent undamaged forest microsite. Physico-chemical characteristics were found to be altered after subsidence, showing a positive impact of subsidence on soil moisture, bulk density, water holding capacity, organic carbon content, total N and total P. The increase in all the parameters was found in depression microsites, while in slope microsites, the values were lower. Fine root biomass and root tips count increased in the subsided depression microsites, as demonstrated by increases of 62% and 45%, respectively. Soil nitrate-N and phosphate-P concentrations were also found to be higher in depression microsite, showing an increase of 35.68% and 24.74%, respectively. Depression microsite has also shown the higher MBN value with an increase over control. Net nitrification, net N-mineralization and MBN were increased in depression microsite by 29.77%, 25.72% and 34%, respectively. There was a positive relation of microbial N with organic C, fine root biomass and root tips.

    Consistent data-recording intervals offer much greater insight into the mechanics of shield dust than the traditional one-reading-per-movement approach. Based on the upstream-downstream comparisons, it would appear that a significant amount of shield-generated dust does occur, and that a large fraction of the upstream content may in fact be from residual shield dust filtering through the canopy gaps. It appears that the vast majority of respirable dust in the walkway occurs during the set cycle. A large amount of visually impressive nuisance debris is dropped during the drop and advance, however, this does not appear to be as dangerous as the set cycle. Not enough consistent data were collected to ascertain any positive, quantifiable cause and effect relationship between dust and debris accumulation, amounts lost, canopy, and checkplate gaps. The graphical plots, however, are extremely suggestive and the next field visits should incorporate a more intensive examination of these parameters. It may also be instructive to follow the mining sequence throughout a mining day, such that shift to shift variations would be minimized and determinable. The canopy gap water sprays could not be tested due to operational constraint.

  2. History of transcontinental railroads and coal mining on the Northern Plains to 1920

    Bryans, W.S.

    1987-01-01

    This history examines the symbiotic relationship between three transcontinental railroads-the Union Pacific, Northern Pacific, and Great Northern-and coal mining in Montana, North Dakota, and Wyoming through 1920. Throughout their dual existence, American railroads and the coal industry enjoyed a mutually beneficial association. On the Northern Plains, however, this partnership assumed new dimensions. There, the coal and rails exerted unique influences upon one another. The location of deposits determined many of the transcontinentals' early decisions, especially route selection. The native fuel also was used to promote settlement on railroad lands. Two of the roads, the Union Pacific and Northern Pacific, held land grants containing valuable deposits. The Great Northern, having no such subsidy, acquired coal lands in northern Montana. On these properties, the three railroads pioneered the region's commercial coal mining industry. Eventually, each formed subsidiaries to direct their coal operations. While much of their production supplied steam locomotives, some was sold to the public. Furthermore, the policies of the Northern Pacific and Great Northern especially enabled their coal to stimulate non-railroad enterprises. In addition, all three provided the transportation which made exploitation by others economically feasible.

    Numerous Stirling machines have been built and operated, but the operating experience of these machines is not well known. It is important to examine this operating experience in detail, because it largely substantiates the claim that Stirling machines are capable of reliable and lengthy lives. The amount of data that exists is impressive, considering that many of the machines that have been built are developmental machines intended to show proof of concept, and were not expected to operate for any lengthy period of time. Some Stirling machines (typically free-piston machines) achieve long life through non-contact bearings, while other Stirling machines (typically kinematic) have achieved long operating lives through regular seal and bearing replacements. In addition to engine and system testing, life testing of critical components is also considered.

    In 1982, Western Energy Company`s Rosebud Mine, located in southeastern Montana, received legal exception, {open_quotes}a first{close_quotes} in Montana to leave a standing mine highwall extending a native bluff. This bluff extension stands 110 feet high and 900 feet long. Normally, all highwalls by law are reduced to a 5:1 slope. This legal exception was accomplished with the support of several governmental agencies and was justified on the highwalls potential value for raptors. Enhancement measures undertaken on the highwall included the construction of three artificial eryies and the release of young prairie falcons (Falco mexicanus) employing hacking methods of the Peregrine Fund. The hack is now in its fourth year with a total of 46 young falcons having been released. Opportunities exist for creating a more diverse habitat for raptors and other cliff obligate species on reclaimed mine lands in the west. It is believed that this practical approach should be explored.

    Numerous Stirling machines have been built and operated, but the operating experience of these machines is not well known. It is important to examine this operating experience in detail, because it largely substantiates the claim that stirling machines are capable of reliable and lengthy operating lives. The amount of data that exists is impressive, considering that many of the machines that have been built are developmental machines intended to show proof of concept, and are not expected to operate for lengthy periods of time. Some Stirling machines (typically free-piston machines) achieve long life through non-contact bearings, while other Stirling machines (typically kinematic) have achieved long operating lives through regular seal and bearing replacements. In addition to engine and system testing, life testing of critical components is also considered. The record in this paper is not complete, due to the reluctance of some organizations to release operational data and because several organizations were not contacted. The authors intend to repeat this assessment in three years, hoping for even greater participation.

  14. Update on use of mine pool water for power generation.

    SciTech Connect (OSTI)

    Veil, J. A.; Puder, M. G.; Environmental Science Division

    2006-09-30

    In 2004, nearly 90 percent of the country's electricity was generated at power plants using steam-based systems (EIA 2005). Electricity generation at steam electric plants requires a cooling system to condense the steam. With the exception of a few plants using air-cooled condensers, most U.S. steam electric power plants use water for cooling. Water usage occurs through once-through cooling or as make-up water in a closed-cycle system (generally involving one or more cooling towers). According to a U.S. Geological Survey report, the steam electric power industry withdrew about 136 billion gallons per day of fresh water in 2000 (USGS 2005). This is almost the identical volume withdrawn for irrigation purposes. In addition to fresh water withdrawals, the steam electric power industry withdrew about 60 billion gallons per day of saline water. Many parts of the United States are facing fresh water shortages. Even areas that traditionally have had adequate water supplies are reaching capacity limits. New or expanded steam electric power plants frequently need to turn to non-traditional alternate sources of water for cooling. This report examines one type of alternate water source-groundwater collected in underground pools associated with coal mines (referred to as mine pool water in this report). In 2003, the U.S. Department of Energy's (DOE's) National Energy Technology Laboratory (NETL) funded Argonne National Laboratory (Argonne) to evaluate the feasibility of using mine pool water in Pennsylvania and West Virginia. That report (Veil et al. 2003) identified six small power plants in northeastern Pennsylvania (the Anthracite region) that had been using mine pool water for over a decade. It also reported on a pilot study underway at Exelon's Limerick Generating Station in southeastern Pennsylvania that involved release of water from a mine located about 70 miles upstream from the plant. The water flowed down the Schuylkill River and augmented the natural flow so that the Limerick plant could withdraw a larger volume of river water. The report also included a description of several other proposed facilities that were planning to use mine pool water. In early 2006, NETL directed Argonne to revisit the sites that had previously been using mine pool water and update the information offered in the previous report. This report describes the status of mine pool water use as of summer 2006. Information was collected by telephone interviews, electronic mail, literature review, and site visits.

    RTOp (reduction/transformation operators) is a collection of C++ software that provides the basic mechanism for implementinig vector operations in a flexible and efficient manner. This is the main interface utilized by Thyra to allow for the specification of specific vector reduction and/or transformation operations. The RTOp package contains three different types of software. (a) a small number of interoperability interfaces. (b) support software including code for the parallel SPMD mode based on only Teuchos::Comm(and notmore » MPl directly(, and (c) a library of pre-implemented RTOp subclasses for everything from simple AXPYs and norms, to more specialized vector operations. RTOp allows an algorithm developer to implement their own RTOp subclasses in a way that is independent from any specific serial, parallel, out-of-core or other type of vector implementation. RTOp is a required package by Thyra and MOOCHO. (c)« less

  13. Analysis of the applicability and probable cost effectiveness of advancing longwall-mining systems in the United States. Final technical report. [Advance vs retreat

    SciTech Connect (OSTI)

    Hill, F.E.; Peake, C.V.; Sharkey, A.

    1981-07-01

    In the first phase of this study it was concluded that there are a number of advancing longwall systems that might well be applicable in the United States and, furthermore, meet the health and safety requirements of MSHA, state inspectors, operating management, and unions. Comparative analyses showed that only two of the advancing-type systems evaluated in the Phase I report failed to approach or better, economically, the typical retreating method in at least some conditions; the others appeared to warrant further attention. And if the mining plan could be worked out to allow for a switch from advancing to retreating after the early years of mining, then almost any combination of advancing and retreating would provide a better return on investment, or in our terms, have a higher net present value than would a typical retreating system. The reason for this lies in the higher initial production rates of the advancing systems and in the lower operating cost and higher ultimate productivity of a retreating system once it is established. After analyzing the advantages and disadvantages of the various advancing longwall systems for a trial program it became apparent that the modified Z System offered the best combination of economic potential and lack of conflict with US mining laws. The major attraction of the modified Z system is that it provides separate roadways to the face for intake air, exhaust air and a beltway. Thus regulatory approval of the ventilation system should not be a major obstacle. The Kaiser Steel Corporation agreed to cooperate with the development of a specification for a trial of the system at its Sunnyside Mine in Utah. The specification was developed for one longwall face to mine a series of panels at Sunnyside.

    1995-11-01

    The U.S. Bureau of Mines evaluated the performance of a catalyzed diesel particulate filter (CDPF) and a CDPF combined with a diesel oxidation catalyst (DOC) at two metal mines. This paper describes the results from the two field evaluations. The CDPF/DOC was installed on an Elphinstone load-haul-dump (LHD) powered by a Caterpillar 3306 prechambered, turbocharged engine. The CDPF was installed on a Tamrock diesel-hydraulic roof-bolting jumbo, powered by a Deutz F6L912W engine. The underground evaluation at this mine was more difficult because of frequent movement by the roof-bolting jumbo, variation in the daily workload, tremendous fluctuation in ventilation air flow rate and the use of a high sulfur diesel fuel, which promotes the formation of sulfate particles, decreases filtration efficiency, and hastens the deterioration of the catalyst.

  17. Method and apparatus for measuring incombustible content of coal mine dust using gamma-ray backscatter

    DOE Patents [OSTI]

    Armstrong, Frederick E.

    1976-09-28

    Method and apparatus for measuring incombustible content of particulate material, particularly coal mine dust, includes placing a sample of the particulate material in a container to define a pair of angularly oriented surfaces of the sample, directing an incident gamma-ray beam from a radiation source at one surface of the sample and detecting gamma-ray backscatter from the other surface of the sample with a radiation detector having an output operating a display to indicate incombustible content of the sample. The positioning of the source and detector along different surfaces of the sample permits the depth of the scattering volume defined by intersection of the incident beam and a detection cone from the detector to be selected such that variations in scattered radiation produced by variations in density of the sample are compensated by variations in the attenuation of the incident beam and the gamma-ray backscatter.

    1982-04-01

    This report summarizes the results of a study to characterize and quantify the occurrence and impact of outby haulage delays on production in US underground coal mines. An instrumentation system employing digital data loggers was used to acquire data for over 500 belt shifts in six mines. Observers collected section production data and section delay data to supplement the haulage database. A statistical data reduction system was applied to develop statistics on failure rates and delay lengths. A production impact model was developed and applied to analyze the effect of reducing delays and implementing engineering changes to the haulage systems. Analytical investigations of the relationship between delays and mine characteristics were conducted, and the impact of feeder-breakers and bunkerage, and the addition of longwall units to existing mines was investigated. The study provides a quantitative information base on underground belt haulage delays for use by mining companies and mining researchers.

    1995-12-01

    We use extended x-ray adsorption fine structure (EXAFS) spectroscopy to examine the chemical environment of zinc (1-2 wt. %), lead (300-600 ppm) and cadmium (50-200 ppm) in complex acid mine drainage sediments from the Tri-State Mining District (KS, MO, OK). The sediments in streams draining tailings piles and open mine shafts are dominated by quartz or amorphous iron hydroxides; accessory minerals include calcite. The bulk water chemistry is buffered by the limestone geology and is undersaturated with respect to pure heavy metal carbonates and hydroxides. EXAFS spectra of the sediment samples were taken at SSRL with a fluorescence detector at low temperature ({approximately}10 K). Heavy metals do not form pure carbonate or hydroxide phases, nor do they appear to sorb to quartz surfaces. In sediments near the mine source, the metals are present primarily as sulfides, the original host mineral. With increasing distance from the source, second-neighbor backscattering from Fe indicates that the metals leached from the sulfides are taken up with amorphous iron hydroxides.

    1980-10-31

    The study assesses the major economic benefits and costs that are associated with the enforcement of the Surface Mining Control and Reclamation ACt (SMCRA). The report addresses the benefits of surface coal mining and land reclamation that follow from the Act. As originally conceived, the study was to evaluate, preferably in monetary terms, the specific benefits and socio-economic impacts of SMCRA. However, it was apparent, in the course of the initial analysis, that historical evaluation of specific benefits and socio-economic/environmental impacts is complicated by the short time that SMCRA has been in operation. It was also apparent that development of substantive, and defensible, quantified estimates of benefits and impacts is hindered by the absence of a great deal of needed numerical data, and by incomplete understanding of the reclamation processes that the Act is intended to enhance. Rather than attempt to evaluate specific benefits and socio-economic/environmental impacts, the study evaluated existing research studies on the impacts of surface mining, land reclamation, and SMCRA, and evaluated existing data sources relevant to surface mining, land reclamation, and SMCRA.

    2007-01-19

    The operation of an APPLE II based undulator beamline with all its polarization states (linear horizontal and vertical, circular and elliptical, and continous variation of the linear vector) requires an effective description allowing an automated calculation of gap and shift parameter as function of energy and operation mode. The extension of the linear polarization range from 0 to 180 deg. requires 4 shiftable magnet arrrays, permitting use of the APU (adjustable phase undulator) concept. Studies for a pure fixed gap APPLE II for the SLS revealed surprising symmetries between circular and linear polarization modes allowing for simplified operation. A semi-analytical model covering all types of APPLE II and its implementation will be presented.

    Some specific points of the Frascati Tokamak Upgrade (FTU) operation are presented for plasma performance as well as for the machine availability and the development of new tools needed to operate in a complex scenario needed for tokamak research. The different techniques adopted for wall conditioning of the FTU are reviewed. Plasmas with low Z{sub eff} have been achieved including those at low density and high additional heating power. The obtained experimental results are discussed in terms of better operation and plasma performance achieved. As with any other large - and thus long-lasting - experiments, a mixture of old and new technological solutions inserted in an open source framework characterizes the FTU data control and acquisition systems. We give some information on the original architecture and try to detail its current state. The high level of reliability presently achieved is discussed.

    The purpose of this study was to determine if living close to the Big River Mine Tailings Superfund site increased blood lead levels of resident children and what contribution mining waste had to any increase. The results of this study indicated that blood lead levels were a product of exposure to lead mining waste, lead-based paint, and other sources. Because the only substantial difference between the study and control areas, in terms of exposure to lead, was the presence of lead mining, mining waste is the reasonable explanation for the difference between the blood lead levels in the two communities.

    Hendryx, M.; Ahern, M.M.

    2009-07-15

    We examined elevated mortality rates in Appalachian coal mining areas for 1979-2005, and estimated the corresponding value of statistical life (VSL) lost relative to the economic benefits of the coal mining industry. We compared age-adjusted mortality rates and socioeconomic conditions across four county groups: Appalachia with high levels of coal mining, Appalachia with lower mining levels, Appalachia without coal mining, and other counties in the nation. We converted mortality estimates to VSL estimates and compared the results with the economic contribution of coal mining. We also conducted a discount analysis to estimate current benefits relative to future mortality costs. The heaviest coal mining areas of Appalachia had the poorest socioeconomic conditions. Before adjusting for covariates, the number of excess annual age-adjusted deaths in coal mining areas ranged from 3,975 to 10,923, depending on years studied and comparison group. Corresponding VSL estimates ranged from $18.563 billion to $84.544 billion, with a point estimate of $50.010 billion, greater than the $8.088 billion economic contribution of coal mining. After adjusting for covariates, the number of excess annual deaths in mining areas ranged from 1,736 to 2,889, and VSL costs continued to exceed the benefits of mining. Discounting VSL costs into the future resulted in excess costs relative to benefits in seven of eight conditions, with a point estimate of $41.846 billion.

    The Intelligent Potroom Operation project focuses on maximizing the performance of an aluminum smelter by innovating components for an intelligent manufacturing system. The Intelligent Potroom Advisor (IPA) monitors process data to identify reduction cells exhibiting behaviors that require immediate attention. It then advises operational personnel on those heuristic-based actions to bring the cell back to an optimal operating state in order to reduce the duration and frequency of substandard reduction cell performance referred to as ''Off-Peak Modes'' (OPMs). Techniques developed to identify cells exhibiting OPMs include the use of a finite element model-based cell state estimator for defining the cell's current operating state via advanced cell noise analyses. In addition, rule induction was also employed to identify statistically significant complex behaviors that occur prior to OPMs. The intelligent manufacturing system design, concepts and formalisms developed in this project w ere used as a basis for an intelligent manufacturing system design. Future research will incorporate an adaptive component to automate continuous process improvement, a technology platform with the potential to improve process performance in many of the other Industries of the Future applications as well.

    Preliminary analysis of the data from the Emery Wilberg Mine evaluation showed that the intake dust level and ventilation conditions were virtually constant throughout the evaluation. These factors coupled with the consistent cutting sequence of the shearer appear to have resulted in very reliable data. The evaluation examined four major test conditions: open stageloader with baseline sprays (10 gpm); open stageloader with all spraybars operating (20 gpm); covered stageloader with baseline sprays (10 gpm); and covered stageloader with all spraybars operating (20 gpm). Data was recorded during both the cutting and clean-up passes. Very little dust was generated during the clean-up pass. Any dust reductions due to improved conditions were difficult to detect because of low dust levels. During the cutting pass, dust levels were considerably higher and the improvements were quite obvious. With an open stageloader the changes from baseline conditions to that of all spray systems operating produced dust reductions of up to 50 percent within the headgate and a 30 percent improvement at shield number 20. Under baseline operating conditions, the dust levels produced with an open stageloader were compared with the levels produced with the stageloader covered. The results showed a significant improvement in the discharge region of the crusher, with 40 percent improvements at the headgate operator and shield number 20. It appears that covering the stageloader provides the largest reduction in dust levels. The application of additional water to the spraybars produced further improvements. Reductions in belt entry dust levels were directly related to the amount of water applied to the stageloader to belt transfer point spraybar.

    In-situ recovery (ISR) of uranium (U) from sandstone-type roll-front deposits is a technology that involves the injection of solutions that consist of ground water fortified with oxygen and carbonate to promote the oxidative dissolution of U, which is pumped to recovery facilities located at the surface that capture the dissolved U and recycle the treated water. The ISR process alters the geochemical conditions in the subsurface creating conditions that are more favorable to the migration of uranium and other metals associated with the uranium deposit. There is a lack of clear understanding of the impact of ISR mining on themore » aquifer and host rocks of the post-mined site and the fate of residual U and other metals within the mined ore zone. We performed detailed petrographic, mineralogical, and geochemical analyses of several samples taken from about 7 m of core of the formerly the ISR-mined Smith Ranch–Highland uranium deposit in Wyoming. We show that previously mined cores contain significant residual uranium (U) present as coatings on pyrite and carbonaceous fragments. Coffinite was identified in three samples. Core samples with higher organic (> 1 wt.%) and clay (> 6–17 wt.%) contents yielded higher 234U/238U activity ratios (1.0–1.48) than those with lower organic and clay fractions. The ISR mining was inefficient in mobilizing U from the carbonaceous materials, which retained considerable U concentrations (374–11,534 ppm). This is in contrast with the deeper part of the ore zone, which was highly depleted in U and had very low 234U/238U activity ratios. This probably is due to greater contact with the lixiviant (leaching solution) during ISR mining. EXAFS analyses performed on grains with the highest U and Fe concentrations reveal that Fe is present in a reduced form as pyrite and U occurs mostly as U(IV) complexed by organic matter or as U(IV) phases of carbonate complexes. Moreover, U–O distances of ~ 2.05 Å were noted, indicating the potential formation of other poorly defined U(IV/VI) species. We also noted a small contribution from Udouble bond; length as m-dashO at 1.79 Å, which indicates that U is partially oxidized. There is no apparent U–S or U–Fe interaction in any of the U spectra analyzed. However, SEM analysis of thin sections prepared from the same core material reveals surficial U associated with pyrite which is probably a minor fraction of the total U present as thin coatings on the surface of pyrite. Our data show the presence of different structurally variable uranium forms associated with the mined cores. U associated with carbonaceous materials is probably from the original U mobilization that accumulated in the organic matter-rich areas under reducing conditions during shallow burial diagenesis. U associated with pyrite represents a small fraction of the total U and was likely deposited as a result of chemical reduction by pyrite. Our data suggest that areas rich in carbonaceous materials had limited exposure to the lixiviant solution, continue to be reducing, and still hold significant U resources. Because of their limited access to fluid flow, these areas might not contribute significantly to post-mining U release or attenuation. Areas with pyrite that are accessible to fluids seem to be more reactive and could act as reductants and facilitate U reduction and accumulation, limiting its migration.« less

    The initial four sections treat basic information concerning atomic structure and other useful physical quantities, natural radioactivity, the properties of {alpha}, {beta}, {gamma}, x rays and neutrons, and the concepts and units of radiation dosimetry (including SI units). Section 5 deals with biological effects and the risks associated with radiation exposure. Background radiation and man-made sources are discussed next. The basic recommendations of the ICRP concerning dose limitations: justification, optimization (ALARA concepts and applications) and dose limits are covered in Section seven. Section eight is an expanded version of shielding, and the internal dosimetry discussion has been extensively revised to reflect the concepts contained in the MIRD methodology and ICRP 30. The remaining sections discuss the operational health physics approach to monitoring radiation. Individual sections include radiation detection principles, instrument operation and counting statistics, health physics instruments and personnel monitoring devices. The last five sections deal with the nature of, operation principles of, health physics aspects of, and monitoring approaches to air sampling, reactors, nuclear safety, gloveboxes and hot cells, accelerators and x ray sources. Decontamination, waste disposal and transportation of radionuclides are added topics. Several appendices containing constants, symbols, selected mathematical topics, and the Chart of the Nuclides, and an index have been included.

    Over the last few years, many embankments and levees have collapsed during strong earthquakes or floods. In the Friuli Venezia Giulia Region (North-Eastern Italy), the main source of this type of risk is a slag deposit of about 2x10{sup 6} m{sup 3} deriving from galena and lead mining activity until 1991 in the village of Raibl. For the final remedial action plan, several in situ tests were performed: five boreholes equipped with piezometers, four CPTE and some geophysical tests with different approaches (refraction, ReMi and HVSR). Laboratory tests were conducted on the collected samples: geotechnical classification, triaxial compression tests and constant head permeability tests in triaxial cell. Pressure plate tests were also done on unsaturated slag to evaluate the characteristic soil-water curve useful for transient seepage analysis. A seepage analysis was performed in order to obtain the maximum pore water pressures during the intense rainfall event which hit the area on 29th August 2003. The results highlight that the slag low permeability prevents the infiltration of rainwater, which instead seeps easily through the boundary levees built with coarse materials. For this reason pore water pressures inside the deposits are not particularly influenced by rainfall intensity and frequency. Seismic stability analysis was performed with both the pseudo-static method, coupled with Newmark's method, and dynamic methods, using as design earthquake the one registered in Tolmezzo (Udine) on 6{sup th} May 1976. The low reduction of safety factors and the development of very small cumulative displacements show that the stability of embankments is assured even if an earthquake of magnitude 6.4 and a daily rainfall of 141.6 mm occur at the same time.

    Despite the focus on the so-called ''high-tech'' and service components of the economy, the minerals industry in 1987 continued to provide the world the overwhelmingly dominant share of the total raw material supply for all manufacturing operations. And, in the form of fertilizers and other soil treatment materials, minerals also supplied indispensable raw materials to ensure continued high production of the agricultural and forestry sector of the world's economy. Moreover, the role of minerals as a source of construction raw materials was essential to that sector. On the basis of preliminary and partial statistics on world output of crude mineral commodities, 1987 appears to have been a year of further recovery from the recessional years of 1981-1983. The value of world crude mineral industry production (all mineral commodities including fuels) apparently advanced about 5% to nearly *1.1 trillion in terms of constant 1983 dollars. That is significantly above the recently revised 1986 level of nearly *1.05 trillion, but still considerably below the record-to-date high of *1.27 trillion set in 1980.

    A site-specific study on stabilizing acid-generating mine tailings from Sudbury Mine using a coal fly ash from Nanticoke Generating Station is presented in this paper. The objective of the study is to evaluate the feasibility of codisposal of the fly ash and mine tailings to reduce environmental impacts of Sudbury tailings disposal sites. The study includes three phases, i.e., characterization of the mine tailings, and coal fly ash, oxidation tests on the mine tailings and kinetic column permeation tests. The results of the experiments indicate that when permeated with acid mine drainage, the hydraulic conductivity of Nanticoke coal fly ash decreased more than three orders of magnitude (from 1 x 10{sup -6} to 1 x 10{sup -9} cm/s), mainly due to chemical reactions between the ash solids and acid mine drainage. Furthermore, the hydraulic gradient required for acid mine drainage to break through the coal fly ash is increased up to ten times (from 17 to 150) as compared with that for water. The results also show that the leachate from coal fly ash neutralizes the acidic pore fluid of mine tailings. The concentrations of trace elements in effluents from all kinetic column permeation tests indicated that coplacement of coal fly ash with mine tailings has the benefit of immobilizing trace elements, especially heavy metals. All regulated element concentrations from effluent during testing are well below the leachate quality criteria set by the local regulatory authority.

In this work, we take an approach to enabling GM capabilities (e.g., PageRank, connected-component analysis, node eccentricity, etc.) in RDF triplestores, which are originally developed to store RDF datasets and provide OLGAP capability. More specifically, to achieve our goal, we implemented six representative graph mining algorithms using SPARQL. The approach allows a wide range of available RDF data sets directly applicable for holistic graph analysis within a system. For validation of our approach, we evaluate performance of our implementations with nine real-world datasets and three different computing environments - a laptop computer, an Amazon EC2 instance, and a shared-memory Cray XMT2 URIKA-GD graph-processing appliance.

    The RAVEN code is becoming a comprehensive tool to perform probabilistic risk assessment, uncertainty quantification, and verification and validation. The RAVEN code is being developed to support many programs and to provide a set of methodologies and algorithms for advanced analysis. Scientific computer codes can generate enormous amounts of data. To post-process and analyze such data might, in some cases, take longer than the initial software runtime. Data mining algorithms/methods help in recognizing and understanding patterns in the data, and thus discovers knowledge in databases. The methodologies used in the dynamic probabilistic risk assessment or in uncertainty and error quantification analysis couple system/physics codes with simulation controller codes, such as RAVEN. RAVEN introduces both deterministic and stochastic elements into the simulation while the system/physics code model the dynamics deterministically. A typical analysis is performed by sampling values of a set of parameter values. A major challenge in using dynamic probabilistic risk assessment or uncertainty and error quantification analysis for a complex system is to analyze the large number of scenarios generated. Data mining techniques are typically used to better organize and understand data, i.e. recognizing patterns in the data. This report focuses on development and implementation of Application Programming Interfaces (APIs) for different data mining algorithms, and the application of these algorithms to different databases.

    The authors discuss the {open_quotes}Labor Management Positive Change Process{close_quotes} (LMPCP) and the Marissa Mine. In the 1993 National Bituminous Coal Wage Agreement, there is a provision that allows for the establishment of the UMWA-BCOA labor management positive change process. This process provides the mechanism to deal with change. The major goal of this process is to increase job security, competitiveness, financial stability and opportunity for all employees covered by the agreement. The authors discuss the Marissa story concerning the LMPCP process. The process established some goals for the Marissa Mine. The main and most important goal was that the mine continue beyond the year 2000. They wanted to develop and implement a more cooperative working relationship; a relationship based on honesty, integrity, and mutual trust. They also wanted to utilize employees` responsibilities, skills, and ideas. They wanted to reinforce the shared belief that an ongoing partnership between labor and management is essential to the long-term success and growth of the industry. The results of some of the issues that were addressed include: employment has increased from 281 union employees to 332 employees; production increased from 3.1 million tons to 4.1 million tons; cost per ton was lowered over $5.00 per ton in the last two years; accidents have been reduced by 50 percent; the process has increased sales and helped develop new sales; and they have been able to improve attitudes among employees.

    The Iraq Department of Border Enforcement is rich in personnel, but poor in equipment. An effective border control system must include detection, discrimination, decision, tracking and interdiction, capture, identification, and disposition. An equipment solution that addresses only a part of this will not succeed, likewise equipment by itself is not the answer without considering the personnel and how they would employ the equipment. The solution should take advantage of the existing in-place system and address all of the critical functions. The solutions are envisioned as being implemented in a phased manner, where Solution 1 is followed by Solution 2 and eventually by Solution 3. This allows adequate time for training and gaining operational experience for successively more complex equipment. Detailed descriptions of the components follow the solution descriptions. Solution 1 - This solution is based on changes to CONOPs, and does not have a technology component. It consists of observers at the forts and annexes, forward patrols along the swamp edge, in depth patrols approximately 10 kilometers inland from the swamp, and checkpoints on major roads. Solution 2 - This solution adds a ground sensor array to the Solution 1 system. Solution 3 - This solution is based around installing a radar/video camera system on each fort. It employs the CONOPS from Solution 1, but uses minimal ground sensors deployed only in areas with poor radar/video camera coverage (such as canals and streams shielded by vegetation), or by roads covered by radar but outside the range of the radar associated cameras. This document provides broad operational requirements for major equipment components along with sufficient operational details to allow the technical community to identify potential hardware candidates. Continuing analysis will develop quantities required and more detailed tactics, techniques, and procedures.

    Krook, Joakim; Svensson, Niclas; Eklund, Mats

    2012-03-15

    Highlights: Black-Right-Pointing-Pointer We analyze two decades of landfill mining research regarding trends and topics. Black-Right-Pointing-Pointer So far landfill mining has mainly been used to solve waste management issues. Black-Right-Pointing-Pointer A new perspective on landfills as resource reservoirs is emerging. Black-Right-Pointing-Pointer The potential of resource extraction from landfills is significant. Black-Right-Pointing-Pointer We outline several key challenges for realization of resource extraction from landfills. - Abstract: Landfills have historically been seen as the ultimate solution for storing waste at minimum cost. It is now a well-known fact that such deposits have related implications such as long-term methane emissions, local pollution concerns, settling issues and limitations on urban development. Landfill mining has been suggested as a strategy to address such problems, and in principle means the excavation, processing, treatment and/or recycling of deposited materials. This study involves a literature review on landfill mining covering a meta-analysis of the main trends, objectives, topics and findings in 39 research papers published during the period 1988-2008. The results show that, so far, landfill mining has primarily been seen as a way to solve traditional management issues related to landfills such as lack of landfill space and local pollution concerns. Although most initiatives have involved some recovery of deposited resources, mainly cover soil and in some cases waste fuel, recycling efforts have often been largely secondary. Typically, simple soil excavation and screening equipment have therefore been applied, often demonstrating moderate performance in obtaining marketable recyclables. Several worldwide changes and recent research findings indicate the emergence of a new perspective on landfills as reservoirs for resource extraction. Although the potential of this approach appears significant, it is argued that facilitating implementation involves a number of research challenges in terms of technology innovation, clarifying the conditions for realization and developing standardized frameworks for evaluating economic and environmental performance from a systems perspective. In order to address these challenges, a combination of applied and theoretical research is required.

    Displacement and stress changes in cemented backfill and ore pillars at the Buick Mine, near Boss, MO, were monitored by engineers from the U.S. Bureau of Mines (USBM) and The Doe Run Co., St Louis, MO. A test area in this room-and-pillar mine was backfilled to provide support when remnant ore pillars were mined. Objectives of this research were to evaluate the effect of backfill on mine stability, observe backfill conditions during pillar removal, and calibrate a numeric model to be used to design other areas of the mine. Two-dimensional, finite-element and three-dimensional, displacement-discontinuity codes were used to model the study area. Combined with instrument data, these codes identified two failed pillars.

    This report presents the results of Run 261 performed at the Advanced Coal Liquefaction R & D Facility in Wilsonville, Alabama. The run started on January 12, 1991 and continued until May 31, 1991, operating in the Close-Coupled Integrated Two-Stage Liquefaction mode processing Illinois No. 6 seam bituminous coal (from Burning star No. 2 mine). In the first part of Run 261, a new bimodal catalyst, EXP-AO-60, was tested for its performance and attrition characteristics in the catalytic/catalytic mode of the CC-ITSL process. The main objective of this part of the run was to obtain good process performance in the low/high temperature mode of operation along with well-defined distillation product end boiling points. In the second part of Run 261, Criterion (Shell) 324 catalyst was tested. The objective of this test was to evaluate the operational stability and catalyst and process performance while processing the high ash Illinois No. 6 coal. Increasing viscosity and preasphaltenes made it difficult to operate at conditions similar to EXP-AO-60 catalyst operation, especially at lower catalyst replacement rates.

    This paper discusses in detail the process undertaken to mitigate the effects of any future mine subsidence on prison structures proposed above old abandoned underground workings. The site for a proposed prison complex purchased by the State of Indiana was located in west-central Indiana and was undermined by an old abandoned room and pillar mine. The original plan for construction consisted of one phase. Based on a study of the mine map and subsurface verification of the extent of mining it was determined that all prison buildings and important structures could be placed above solid coal to the north. One masonry building, however, was located within the potential draw zone of mine works which still contained significant mine voids. Based on empirical data the subsidence potential was estimated and the building was accordingly designed to be mine subsidence resistant. It was decided that a phase two prison complex should be constructed adjacent to and just south of the Phase I complex. This complex would be directly above the underground workings. The first stage of design was to minimize subsidence potential by positioning the exposure of significant structures to the subjacent mining assuming the mine map was sufficiently accurate. Subsequently, an extensive subsurface investigation program was then undertaken to: (1) ascertain whether or not mine areas where buildings would be located were already collapsed and thus only nominal, if any, subsidence could occur in the future; and (2) verify the presence of solid coal areas within the mine as indicated on the mine map. Based on all the site information gathered subsidence profiles were developed from an empirical data base of subsidence events in the Illinois Coal Basin. As a result of this work many structures on the site required no or nominal subsidence considerations.

    The paper describes the bases of a new application of GIS-technologies for integrated assessment and comparison of the productive mining areas, involving a wide range of mining and technological factors, considering mineral properties, mineral occurrence conditions and geographical advantages of a mineral deposit location. The model capabilities are exemplified by a comparison of technological characteristics of coals, transportation and power supply infrastructure of the productive mining areas at the Kuznetsk Coal Basin.

    The long term impact of surface mining on vegetation and plant succession has always been of concern to environmentalists and residents of Appalachia. The Fonde Surface Mine Demonstration Area is a 7.3-ha, NE-NW-aspect contour coal mine at an elevation of 562 m. It was reclaimed in 1965 to show state-of-the-art surface mine reclamation techniques consistent with then-current law and regulations after coal mining in 1959 and 1963. The mine spoils were lightly graded to control erosion and crates a bench with water control and two sediment ponds. Soil pH ranged from 2.8 to 5.9. About 80 percent of the mine was planted with 18 tree and shrub species including plantations of mixed pine, mixed hardwoods, black locust, and shrubs for wildlife. In a complete floristic inventory conducted 25 years later, the authors found the woody flora consisted of 34 families, 53 genera, and 70 species including 7 exotics. This inventory of the Fonde mine shows that a diverse forest vegetation can be reestablished after extreme disturbances in Appalachia. Black locust, yellow poplar, and Virginia pine reproduction varied significantly among plantation types. Canopy tree species significantly affected ground layer cover, total species richness, number of tree seedling species, and total number of tree seedlings present. Mine soil type affected ground layer percent cover and total species richness. Pre-SMCRA (Surface Mining Control and Reclamation Act of 1977) reclaimed and inventoried mines can be used to evaluate biodiversity on post-SMCRA mines.

    This report documents measurements and analytical modeling of electromagnetic transfer functions to quantify the ability of cloud-to-ground lightning strokes (including horizontal arc-channel components) to couple electromagnetic energy into the Sago mine located near Buckhannon, WV. Two coupling mechanisms were measured: direct and indirect drive. These transfer functions are then used to predict electric fields within the mine and induced voltages on conductors that were left abandoned in the sealed area of the Sago mine.
