Assessment of effective parameters on dilution using approximate reasoning methods in longwall mining method, Iran coal mines  

E-Print Network [OSTI]

Approximately more than 90% of all coal production in Iranian underground mines is derived directly longwall mining method. Out of seam dilution is one of the essential problems in these mines. Therefore the dilution can impose the additional cost of mining and milling. As a result, recognition of the effective parameters on the dilution has a remarkable role in industry. In this way, this paper has analyzed the influence of 13 parameters (attributed variables) versus the decision attribute (dilution value), so that using two approximate reasoning methods, namely Rough Set Theory (RST) and Self Organizing Neuro- Fuzzy Inference System (SONFIS) the best rules on our collected data sets has been extracted. The other benefit of later methods is to predict new unknown cases. So, the reduced sets (reducts) by RST have been obtained. Therefore the emerged results by utilizing mentioned methods shows that the high sensitive variables are thickness of layer, length of stope, rate of advance, number of miners, type of...

Longwall mining of thin seams  

SciTech Connect (OSTI)

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.

Evaluating the impact of longwall coal mining on the hydrologic balance  

SciTech Connect (OSTI)

An approach has been developed to evaluate changes in the hydrologic balance associated with land subsidence above longwall mining operations in the Appalachian Coal Basin. This method consists of developing hydrogeologic cross sections to define specific aquifers and aquitards which exist within the overburden. The cross sections can be used to define the premining hydrologic flow pattern within the mine overburden and the lithologic composition of a well, spring or pond where no previous data were available. Then the water sources are mapped in relationship to the mine development plan. Hydrographs are developed to evaluate changes in water level in a well or the flow characteristics of a spring or stream with respect to the passing of the longwall mine face. To demonstrate the use of the technique, two mine site case histories are presented. These case histories evaluate changes in the hydrologic balance as they relate to potential ground-water depletion of wells, developed springs, streams and surface-water impoundments.

Influence of lithology on longwall mining subsidence  

SciTech Connect (OSTI)

The US Bureau of Mines assessed the geological effects on the ratio of maximum subsidence and extraction thickness, known as the subsidence factor, to develop a simple method for predicting the maximum subsidence. This study is restricted to the Northern Appalachian Coal Basin where data were collected from 13 coal mines. A model previously developed to relate the subsidence factor with the lithology and with the width and depth of working panels was used in the assessment. The result shows the possibility of determining maximum subsidence without resorting to a rigorous method.

Analysis of longwall pillar stability  

SciTech Connect (OSTI)

This dissertation proposes a new method for longwall pillar design, developed primarily from underground measurements. This dissertation addresses three areas of direct relevance to longwall pillar design: (1) The magnitude, time-of-arrival, and distribution of the abutment loads applied to longwall pillars; (2) The strength and behavior of coal pillars; (3) The relationship between pillar sizing and entry stability, and other factors affecting the roof/pillar/floor interaction during longwall mining. The research focused on two field studies performed in adjacent longwall panels at a West Virginia coal mine. In each study, measurements of pillar stress, pillar deformation, and entry stability were obtained during and after the approach of the longwall face. Other research included detailed reanalyses of field data from other studies, an in-depth comparative study of available longwall pillar design methods, numerical modeling to determine post-development longwall pillar loads, and an evaluation of two index tests used to determine coal strength. The proposed longwall pillar design method incorporates a new approach to estimating abutment loads hat was developed from the research. The method also employs existing empirical pillar strength formulas that were shown to be applicable to longwall pillars. The proposed design method represents an improvement over the existing methods, because it can be used with designs employing combinations of differently sized pillars, and because it can calculate stability factors for the several different service functions of pillars around a longwall.

Design of coal mine roof support and yielding pillars for longwall mining in the Appalachian coalfield  

SciTech Connect (OSTI)

In this thesis, the existing Geomechanics Classification (Bieniawski, 1979) was modified for use in underground coal mines through the introduction of adjustment modifiers for strata weathering, horizontal stress, and roof support. Sixty-two roof case histories were collected from two mines exploiting the Pittsburgh and Lower Kittanning coal seams. Geologic and material property variables were examined with respect to supported stand-up time, while survival and regression analyses were used in deriving the adjustment multipliers. Guidelines for roofspan selection and roof support design were an integral facet of the modified classification scheme. Tentative design guidelines for chain pillars are provided on the basis of a field investigation and numerical modeling of longwall chain pillar behavior. A longwall chain pillar was instrumented with vibrating wire stressmeters to quantify the change in stress distribution as longwall mining proceeded out by the pillar. A sonic probe was used to conduct a velocity profile across the pillar before and after mining to delineate the failed and stable regions of the pillar. Velocity profiles across the pillar were supplemented by an examination of changes in the dynamic modulus and the shear wave frequency. The main contributions of the research lies in: (i) modifications introduced to the Geomechanics Classification (RMR System), (ii) the correlation between changes in pillar stress and the extent of the yield zone surrounding a longwall chain pillar, and (iii) the proposal of design procedures involving coal mine roof support and chain pillars. Numerical examples obtained from mine case histories are provided to illustrate the use of the design procedures.

Demonstration of shield-type longwall supports at York Canyon Mine of Kaiser Steel Corporation. Final technical report A  

SciTech Connect (OSTI)

This report represents work on a program that was originated by the USBM of the Department of the Interior and was transferred to the Department of Energy on October 1, 1977. A demonstration with the Government funded Hemscheidt 320 HSL caliper type shield supports was conducted at three longwall panels of Kaiser Steel Corporation's York Canyon Mine. The purpose of this longwall demonstration was to provide the US coal industry with information on all aspects of shield longwall mining in high seams. The demonstration provided a working model for the coal industry and during the project, 350 people from the industry, schools, and government agencies visited the demonstration. They were provided with a first hand knowledge of a working shield longwall. The demonstration showed that the control of large coal lumps may be a problem in the mining of coal seam thicker than 8 feet. Mining with shield type supports provided good working conditions and a safe working environment. The shield requires very little maintenance and has a high mechanical availability.

Strata-movement concepts and the hydrogeological impact of underground coal mining. [Effects of subsidence on permeability of rock above longwall  

SciTech Connect (OSTI)

A review of mining-engineering concepts and studies in mine hydrology suggests a conceptual model linking the strata deformation, hydraulic property changes, and ground-water impacts due to underground coal mining. The pressure-arch deformation pattern about a small opening creates a local zone of increased permeabilities and dewatering in the seam and immediate roof, but should not hydraulically affect shallower aquifiers. Networks of supported headings, rooms, and pillars intensely drain lower aquifiers but only slightly affect higher strata except in areas of naturally high permeability. Longwall mining causes extensive, high-reaching, well-defined zones of stress, fracturing, and hydraulic impact, the maximum permeability increases being in the tensile zones immediately above the panel and at the sides of the subsidence trough. In shallow aquifiers, permeabilities and ground-water velocities increase, and hydraulic gradients decline independently of mine drainage. A study of a deep coal mine in the Appalachian Plateau, Pennsylvania indicated: probable hydraulic connections between the mine and shallow aquifiers in a principle valley area; no obvious response of water levels in shallow aquifiers to undermining by supported headings; and rapid, considerable declines in such water levels in response to nearby longwall mining. These results are consistent with the conceptual model.

Maximising Longwall performance and profitability by the introduction of moving car bunker systems into outbye haulage layouts  

SciTech Connect (OSTI)

In order to maximize the profitability of Longwall mining operations, outbye materials handling systems should be cost effectively engineered to both fully harmonize with cyclical surges in output and to maintain high levels of availability. With the introduction of new Longwall systems into existing mines, the upgrading of outbye haulage to handle peak production from the Longwall panel can prove to be extremely expensive and is often unnecessary. In addition, despite high levels of investment in new equipment, many mines are still failing to achieve planned gains in Longwall productivity due to persistent downtime on outbye haulage routes. This paper details the planning, production and engineering considerations necessary to maximize profitability by the introduction of moving car bunker systems to underground haulage layouts. It also examines case studies of recent installations within the North American coal mining industry and charts the significant success being achieved in improving profitability at these mines.

Prediction of surface deformations over longwall panels in the Northern Appalachian Coalfield  

SciTech Connect (OSTI)

This paper describes the Bureau of Mines development of a novel subsidence prediction methodology suitable to the mining and geologic conditions in the Northern Appalachian Coal Region. It describes the computation of vertical and horizontal movements, inclination, curvature, and horizontal strains. The substance of this method is the separation of the effects of lithology by introducing a correlation between hypothetically homogenous overburden and existing lithologic conditions, while providing for different mining conditions such as underground geometry and overburden thickness. The effects of lithology have been expressed in the form of a variable subsidence coefficient within the subsidence trough. Results from additional longwall panel studies not included in the regression analysis were used to prove the validity of this method. To facilitate the use of this pre-calculation methodology, a computer program was written in BASIC for use on a personal computer.

Longwall shield design: is bigger better?  

SciTech Connect (OSTI)

This article evaluates the bigger is better design philosophy for longwall shields. The conventional support design approach based on simplistic models of supporting the full dead weight detached rock masses is replaced by a ground reaction design approach. Here, the goal is to match the support characteristics to the ground response, and not to try and overpower the ground forces with some massive support capability. The ground reaction concept embodies both the force and displacement controlled loading aspects, and therefore provides a more accurate representation of the support loading requirements. 7 figs.

4D seismic data acquisition method during coal mining  

Science Journals Connector (OSTI)

In order to observe overburden media changes caused by mining processing, we take the fully-mechanized working face of the BLT coal mine in Shendong mine district as an example to develop a 4D seismic data acquisition methodology during coal mining. The 4D seismic data acquisition is implemented to collect 3D seismic data four times in different periods, such as before mining, during the mining process and after mining to observe the changes of the overburden layer during coal mining. The seismic data in the research area demonstrates that seismic waves are stronger in energy, higher in frequency and have better continuous reflectors before coal mining. However, all this is reversed after coal mining because the overburden layer has been mined, the seismic energy and frequency decrease, and reflections have more discontinuities. Comparing the records collected in the survey with those from newly mined areas and other records acquired in the same survey with the same geometry and with a long time for settling after mining, it clearly shows that the seismic reflections have stronger amplitudes and are more continuous because the media have recovered by overburden layer compaction after a long time of settling after mining. By 4D seismic acquisition, the original background investigation of the coal layers can be derived from the first records, then the layer structure changes can be monitored through the records of mining action and compaction action after mining. This method has laid the foundation for further research into the variation principles of the overburden layer under modern coal-mining conditions.

Inference of strata separation and gas emission paths in longwall overburden using continuous wavelet transform of well logs and geostatistical simulation  

Science Journals Connector (OSTI)

Abstract Prediction of potential methane emission pathways from various sources into active mine workings or sealed gobs from longwall overburden is important for controlling methane and for improving mining safety. The aim of this paper is to infer strata separation intervals and thus gas emission pathways from standard well log data. The proposed technique was applied to well logs acquired through the Mary Lee/Blue Creek coal seam of the Upper Pottsville Formation in the Black Warrior Basin, Alabama, using well logs from a series of boreholes aligned along a nearly linear profile. For this purpose, continuous wavelet transform (CWT) of digitized gamma well logs was performed by using Mexican hat and Morlet, as the mother wavelets, to identify potential discontinuities in the signal. Pointwise Hölder exponents (PHE) of gamma logs were also computed using the generalized quadratic variations (GQV) method to identify the location and strength of singularities of well log signals as a complementary analysis. \\{PHEs\\} and wavelet coefficients were analyzed to find the locations of singularities along the logs. Using the well logs in this study, locations of predicted singularities were used as indicators in single normal equation simulation (SNESIM) to generate equi-probable realizations of potential strata separation intervals. Horizontal and vertical variograms of realizations were then analyzed and compared with those of indicator data and training image (TI) data using the Kruskal–Wallis test. A sum of squared differences was employed to select the most probable realization representing the locations of potential strata separations and methane flow paths. Results indicated that singularities located in well log signals reliably correlated with strata transitions or discontinuities within the strata. Geostatistical simulation of these discontinuities provided information about the location and extents of the continuous channels that may form during mining. If there is a gas source within their zone of influence, paths may develop and allow methane movement towards sealed or active gobs under pressure differentials. Knowledge gained from this research will better prepare mine operations for potential methane inflows, thus improving mine safety.

Computer methods for surface mine evaluation in the Appalachian coalfield  

SciTech Connect (OSTI)

The increasing complexity of surface mining operation has resulted in the development of a number of computer models to describe its operation. In this paper, a modified model is used to analyze critical design parameters of a surface mining operation. Research has indicated that there are several design factors which influence the dozer productivity and consequently the productivity of the entire overburden removal system. These are lift or bench width, lift height, the percentage of the overburden removed by dozer stripping. Several analyses are presented which illustrate the variation of both tons per hour and loose cubic yards per hour with lift width, lift height, and percentage dozed. Using this data, values of critical width, are computed to indicate the cut-offs where trapping productivity exceeds that of both the LHS (load-haul-strip) and LHST (load-haul-strip-trap) extraction. 5 references, 8 figures.

The Kelastic variable wall mining machine. Interim final report  

SciTech Connect (OSTI)

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.

Occupational health and safety regulation in the coal mining industry: public health at the workplace  

SciTech Connect (OSTI)

The strategy for preventing occupational disease and injury in the coal mining industry employs several elements. Standards are set and enforced; technical assistance, research, and development are provided; and surveillance is conducted. Compensation for black lung is a vivid reminder of the consequences of failure to prevent disease. And, workers are represented by a union that encourages active participation in all aspects of this strategy. There are significant problems in each of these elements. Regulatory reform threatens to weaken many standards, there is a decline in government research budgets, surveillance is not well monitored, and compensation for black lung is significantly more difficult to obtain now than in the past. Moreover, the conservative governments of the past decade are not friendly towards unions. Nevertheless, the fundamental structure of disease and injury prevention remains intact and, more importantly, it has a historical record of success. The Mine Safety and Health Act provided for a wide array of basic public health measures to prevent occupational disease and injury in the mining industry. These measures have been effective in reducing both risk of fatal injury and exposure to respirable coal mine dust. They are also associated with temporary declines in productivity. In recent years, however, productivity has increased, while risk of fatal injury and exposure to respirable dust have declined. At individual mines, productivity with longwall mining methods appear to be associated with increases in exposure to respirable dust. These trends are not inconsistent with similar trends following implementation of regulations by OSHA. When OSHA promulgated regulations to control exposure to vinyl chloride monomer, enforcement of the standard promoted significant efficiencies in vinyl chloride production (5).21 references.

Methods of minimizing ground-water contamination from in situ leach uranium mining. Final report  

SciTech Connect (OSTI)

This is the final report of a research project designed to study methods of minimizing ground-water contamination from in situ leach uranium mining. Fieldwork and laboratory experiments were conducted to identify excursion indicators for monitoring purposes during mining, and to evaluate effective aquifer restoration techniques following mining. Many of the solution constituents were found to be too reactive with the aquifer sediments to reliably indicate excursion of leaching solution from the ore zone; however, in many cases, the concentrations of chloride and sulfate and the total dissolved solids level of the solution were found to be good excursion indicators. Aquifer restoration by ground-water sweeping consumed large quantities of ground water and was not effective for the redox-sensitive contaminants often present in the ore zone. Surface treatment methods such as reverse osmosis and electrodialysis were effective in reducing the amount of water used, but also had the potential for creating conditions in the aquifer under which the redox-sensitive contaminants would be mobile. In situ restoration by chemical reduction, in which a reducing agent is added to the solution recirculated through the ore zone during restoration, can restore the ore-zone sediment as well as the ground water. This method could lead to a stable chemical condition in the aquifer similar to conditions before mining. 41 figures.

Investigation into the modeling of ground deformations induced by underground mining  

SciTech Connect (OSTI)

The mechanisms of strata deformation due to underground mining were analyzed in an effort to better understand immediate roof behavior and surface displacements. Strata deformation characteristics above longwall and room-and-pillar mines in the eastern US coal fields were evaluated and a numerical procedure was developed for calculating surface displacements. The model, based on the well-known finite element method, utilized empirical indices associated with subsidence engineering in order to incorporate the site-specific characteristics into the formulation. Different material behavior models and failure criteria were employed in an attempt to determine the areas highly deformed by underground excavation. Additionally, the method was sensitive to the ratios of the elastic moduli used to describe different rocks and/or rock conditions, and not to the magnitude of the elastic properties. Thus, the use of arbitrary reduction factors to convert laboratory to in situ property values was completely avoided and scaling of the calculated surface displacements was based on, the empirically predicted, regional or local parameters. The use of fixed displacement nodes around an opening to induce failure overcame the roof-floor overlap problem encountered in other formulations. The successful implementation of the proposed methodology for modeling surface deformations complements and enhances existing prediction techniques, which are primarily based on empirical approaches, by allowing parametric analysis for different excavation geometries, roof convergence curves and overburden properties.

Precalculation of subsidences over longwall panels in the Northern Appalachian Coal Field  

SciTech Connect (OSTI)

The specific lithological conditions over the Pittsburgh coalbed, highly resistive limestone and sandstone units with relatively shallow overburden, prevent the use of any predictive method as developed for European conditions. This paper describes the development of a subsidence precalculation methodology suitable to the mining-geological conditions in the Northern Appalachian Coal Field. It has been found that due to lithological conditions over the Pittsburgh coalbed the subsidence coefficient varies within the area of the subsidence trough. This is different from the European conditions where the subsidence coefficient is considered to be a constant. The effects of lithology, in the form of a variable subsidence coefficient, have been separated for each test site by introducing a correlation between hypothetically homogeneous overburden and existing lithological conditions, while providing for different mining conditions.

The 'Mine/Yours' method of international comparisons of carbon emissions  

SciTech Connect (OSTI)

In previous work (Schipper, Unander & Lilliu 1999), we summarized a new method for comparing energy use and carbon emissions among various countries. We call this the ''Mine/Yours'' comparison. In this paper, we provide details of the comparisons methodology, and carry out the comparison on a number of IEA countries. We calculate the average energy intensities I for a sample of countries (''yours'') and multiply them by structural parameters S for a particular country (''mine''). Comparing the results with the actual energy use of the country in question gives us an estimate of how much energy that country would use with average intensities but with its own structural conditions. The converse can be calculated as well, that is, average structure and own intensities. Emissions can be introduced through the F (fuel mix) term. These calculations show where differences in the components of emissions lead to large gaps among countries, and where those differences are not important. We show which components cause the largest variance in emissions by sector. In households, home size, average winter climate, and energy intensity appear to be the most important differentiating characteristics for space heating. For other residential energy uses the mix of fuels used to generate electricity (utility mix) is most important. Because some of the differences are ''built in'' - geography, climate, natural resources endowment - we conclude by questioning whether uniform emissions reductions targets make sense. Indeed, the ''Mine/Yours'' tool provides a valuable guide to important ways in which emissions may or may not be flexible.

Look taken at coal mining costs and trends for the 1980s  

SciTech Connect (OSTI)

The author examines the trends in US bituminous coal production and consumption over the past 40 years, and then looks at the growth rates than can be expected for the rest of the 1980s. Increases are likely to be substantial in absolute terms, although nominal when expressed as a percentage. Surface minable reserves in the eastern US are rapidly being depleted, so that underground mining will gain in importance in these regions. A significant contribution to supplying increased domestic coal consumption will eventually come from new longwall mines in the Illinois Basin and northern Appalachia.

Case studies of sealing methods and materials used in the salt and potash mining industries  

SciTech Connect (OSTI)

Sealing methods and materials currently used in salt and potash industries were surveyed to determine if systems analogous to the shaft seal design proposed for the Waste Isolation Pilot Plant (WIPP) exist. Emphasis was first given to concrete and then expanded to include other materials. Representative case studies could provide useful design, construction, and performance information for development of the WIPP shaft seal system design. This report contains a summary of engineering and construction details of various sealing methods used by mining industries for bulkheads and shaft liners. Industrial experience, as determined from site visits and literature reviews, provides few examples of bulkheads built in salt and potash mines for control of water. Sealing experiences representing site-specific conditions often have little engineering design to back up the methods employed and even less quantitative evaluation of seal performance. Cases examined include successes and failures, and both contribute to a database of experiences. Mass salt-saturated concrete placement under ground was accomplished under several varied conditions. Information derived from this database has been used to assess the performance of concrete as a seal material. Concrete appears to be a robust material with successes in several case studies. 42 refs.

Installation of a digital, wireless, strong-motion network for monitoring seismic activity in a western Colorado coal mining region  

SciTech Connect (OSTI)

A seismic monitoring network has recently been installed in the North Fork Valley coal mining region of western Colorado as part of a NIOSH mine safety technology transfer project with two longwall coal mine operators. Data recorded with this network will be used to characterize mining related and natural seismic activity in the vicinity of the mines and examine potential hazards due to ground shaking near critical structures such as impoundment dams, reservoirs, and steep slopes. Ten triaxial strong-motion accelerometers have been installed on the surface to form the core of a network that covers approximately 250 square kilometers (100 sq. miles) of rugged canyon-mesa terrain. Spread-spectrum radio networks are used to telemeter continuous streams of seismic waveform data to a central location where they are converted to IP data streams and ported to the Internet for processing, archiving, and analysis. 4 refs.

Stochastic modeling of mine conveyor/bunker systems  

SciTech Connect (OSTI)

Time studies have revealed that in longwall coal mining the outbye haulage and the face conveyor account for 22% and 27% of the total downtime respectively. The outbye haulage generally is a layout of belt conveyors, which are serially connected. Although bunkers can increase the conveyor system availability, they may not maximize exploitation of the production potential if either the volumes of the bunkers are inadequate or their locations in the system are inappropriate. The availability of the conveyor system in a function of the bunker volume and location. Therefore the determination of the optimum bunker volume and location is important. With the exception of a few studies in the Soviet Union, and the work on the buffer problem in industrial engineering, most mining researchers have used the simulation technique. Because these studies necessarily have unrealistic assumptions, they are of little practical value. The solution to this problem is made difficult because the determination of the system availability becomes complicated because of the presence of the bunker. Although the availability of a system of conveyors can be determined by modeling the system as an ordinary Markov Process, the inclusion of a bunker in the system destroys the Markov Property and precludes the use of conventional Markov Theory. However the supplementary variable technique can be used to model the conveyor/bunker system. Using this technique a formula for the availability of a conveyor/bunker system has been developed in this study. This formula has been used to determine the optimum locations and optimum capacities of one or more bunkers in conveyor systems.

Mined land reclamation by biological reactivation  

SciTech Connect (OSTI)

A mine reclamation technique, developed in Europe, restores land to full productivity within two years without topsoil replacement. The method deliberately reestablishes within one year following mining, the required biological balance between microbes, enzymes, and trace elements in the rock spoil rather than waiting five or more years for natural processes to restore balance. The technique is called Biological Reactivation (BR). This paper discusses the feasibility of BR reclamation after surface mining operations in the US. Staff of the Ohio Mining and Mineral Resources Research Institute completed an OSM-sponsored research project on BR in which physical and chemical tests characterized 140 spoil samples obtained from 10 surface mining operations. Test results indicated that Biological Reactivation technology could be effectively applied, at least in the test areas sampled within Appalachia. Preliminary estimates make clear that the new technique reduces reclamation costs on prime farmland by approximately 95% compared to topsoil segregation and replacement methods.

Testing terrorism theory with data mining  

Science Journals Connector (OSTI)

This research demonstrates the application of multiple data mining techniques to test theories of the macro-level causes of terrorism. The unique dataset is comprised of terrorist events and measures of social, political and economic contexts in 185 countries worldwide between the years 1970 and 2004. The theories are assessed using the iterative expert data mining (IEDM) methodology with classification mining and then association mining. The resulting 100 rules suggest that the level of democracy in a country is an integral part of the explanation for terrorism. This research shows that a multi-method data mining approach can be used to test competing theories in a discipline by analysing large, comprehensive datasets that capture multiple theories and include large numbers of records.

Acoustic resonance for nonmetallic mine detection  

SciTech Connect (OSTI)

The feasibility of acoustic resonance for detection of plastic mines was investigated by researchers at the Oak Ridge National Laboratory`s Instrumentation and Controls Division under an internally funded program. The data reported in this paper suggest that acoustic resonance is not a practical method for mine detection. Representative small plastic anti-personnel mines were tested, and were found to not exhibit detectable acoustic resonances. Also, non-metal objects known to have strong acoustic resonances were tested with a variety of excitation techniques, and no practical non-contact method of exciting a consistently detectable resonance in a buried object was discovered. Some of the experimental data developed in this work may be useful to other researchers seeking a method to detect buried plastic mines. A number of excitation methods and their pitfalls are discussed. Excitation methods that were investigated include swept acoustic, chopped acoustic, wavelet acoustic, and mechanical shaking. Under very contrived conditions, a weak response that could be attributed to acoustic resonance was observed, but it does not appear to be practical as a mine detection feature. Transfer properties of soil were investigated. Impulse responses of several representative plastic mines were investigated. Acoustic leakage coupling, and its implications as a disruptive mechanism were investigated.

Uranium Mining and Enrichment  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Overview Presentation » Uranium Mining and Enrichment Overview Presentation » Uranium Mining and Enrichment Uranium Mining and Enrichment Uranium is a radioactive element that occurs naturally in the earth's surface. Uranium is used as a fuel for nuclear reactors. Uranium-bearing ores are mined, and the uranium is processed to make reactor fuel. In nature, uranium atoms exist in several forms called isotopes - primarily uranium-238, or U-238, and uranium-235, or U-235. In a typical sample of natural uranium, most of the mass (99.3%) would consist of atoms of U-238, and a very small portion of the total mass (0.7%) would consist of atoms of U-235. Uranium Isotopes Isotopes of Uranium Using uranium as a fuel in the types of nuclear reactors common in the United States requires that the uranium be enriched so that the percentage of U-235 is increased, typically to 3 to 5%.

Sustainable heat extraction from abandoned mine tunnels: A numerical model  

Science Journals Connector (OSTI)

Abandoned mines are often associated with enduring liabilities which involve significant costs for decades after the decommissioning of the mine. Using a decommissioned mine as a geothermal resource can offset the environmental costs by supplying green heat to the communities living in and around the mine area. In this paper a numerical assessment of geothermal heat extraction from underground mine workings using an open loop geothermal system is carried out. In this study our focus is on fully flooded mines where the heat flow from the rock mass to the mine cavities is dominantly controlled by conduction in the rock mass. The sustainable heat flux into the mine workings is assessed using a transient two-dimensional axisymmetric heat transfer model. Finite volume method is applied to solve the model and simulate the transient temperature fields in the rock mass and within the water (flowing through cavities). The model is capable of controlling the rate of heat extraction through continuous adjustment of the rate of water flow through the mine. Sustainable rate of heat extraction is calculated for seasonally varied heat loads and for different project life cycles. It is shown that with proper resource management each kilometre of a typical deep underground mine tunnel can produce about 150?kW of usable heat in a sustainable manner. The model is validated by comparing its results with other published models and realistic data available from Springhill mine Nova Scotia Canada. It is found that the sustainable heat extraction is controlled dominantly by virgin rock temperature thermal conductivity of the rock mass and seasonal heat load variations.

Mining the earth  

SciTech Connect (OSTI)

Substances extracted from the earth - stone, iron, bronze - have been so critical to human development that historians name the ages of our past after them. But while scholars have carefully tracked human use of minerals, they have never accounted for the vast environmental damage incurred in mineral production. Few people would guess that a copper mining operation has removed a piece of Utah seven times the weight of all the material dug for the Panama Canal. Few would dream that mines and smelters take up to a tenth of all the energy used each year, or that the waste left by mining measures in the billions of tons - dwarfing the world's total accumulation of more familiar kinds of waste, such as municipal garbage. Indeed, more material is now stripped from the earth by mining than by all the natural erosion of the earth's rivers. The effects of mining operations on the environment are discussed under the following topics: minerals in the global economy, laying waste, at what cost cleaning up, and dipping out. It is concluded that in the long run, the most effective strategy for minimizing new damage is not merely to make mineral extraction cleaner, but to reduce the rich nations needs for virgin (non-recycled) minerals.

Opportunities for improved surface mine reclamation in the central Appalachian coal region  

SciTech Connect (OSTI)

The purpose of this research was to estimate the costs of coal surface mine reclamation methods designed to prepare mined lands for improved use in areas of steeply sloping topography. During the course of this research, a computer-based mining and reclamation cost estimating system was developed. COSTSUM is a set of seven programs designed to analyze data from active surface mining sites to determine spoil handling and reclamation costs. OPSIM is a surface mining simulator designed to estimate the differences in spoil handling costs among reclamation and postmining landform alternatives. This cost-estimating system was utilized during an intensive study of mining and reclamation cost at a surface mining site in Wise County, Virginia, where a number of improved reclamation practices were implemented. At this site, a steeply sloping premining topography was transformed to a postmining landform containing an extensive near-level area covered with deep, uncompacted, potentially productive mine soils. Analysis of daily records of operations revealed that the cost of mining and reclaiming this site was comparable to industry average costs in the area in spite of departure from conventional methods. The results of simulation procedures indicated that the cost of mining so as to produce this landscape was less than the estimated cost of conventional mining methods.

Case study of groundwater impact caused by underground mining  

SciTech Connect (OSTI)

An investigative methodology is presented to assist mining and regulatory personnel in determining the effect underground mining can have on local aquifers in the Appalachian coal region. The impact of underground mining on groundwater may be more extensive than first realized by the mining industry and regulatory agencies. The primary reason for this possible under-assessment of deep mining's influence on groundwater is the methods used to calculate groundwater movement. Since groundwater calculations are based on primary hydraulic conductivity, i.e. the conductivity through solid rock measured from rock core samples, erroneous results may be expected. In many cases, groundwater flow times and the corresponding areas of influence are much greater than those assumed since water is rapidly moved through fractured zones that commonly occur throughout Appalachia. A case study illustrating this phenomenon is drawn from underground mining operations in Pike County. A survey of 144 wells was conducted to determine if any loss of water supply and/or quality was found. This was correlated to the extent and time progression of underground mining operations. Other parameters qualified are water level fluctuations, groundwater quality, precipitation, seasonal effects, geology, and mine dewatering. The analysis includes a comprehensive compilation of a well inventory of domestic water supplies. The case study draws conclusions regarding cause and effect relationships.

Spoil handling and reclamation costs at a contour surface mine in steep slope Appalachian topography  

SciTech Connect (OSTI)

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.

Saving energy in mining  

SciTech Connect (OSTI)

The struggle to reduce power costs is relentless in the world of mining. One of the most significant trends has been the use of electric instead of diesel power in such mining vehicles as large capacity dump trucks, hydraulic excavators, and articulated trucks. The hydraulic excavator, due to its selectivity, high breakout force, and maneuverability, has become increasingly popular as the loading unit in conventional shovel and truck operations. However, hydraulic shovels were originally only available as diesel powered units. Electric power for the prime mover is now offered as an option by most manufacturers. This is particularly cost effective with the larger machines. In surface mines, the transport of coal and overburden consumes the most energy. The application of such technology as in-pit crushers and conveyor systems are all aimed at reducing operating costs. A major development in reducing ventilation energy consumption is the Ventcon system based on the idea of distributing ventilation air more effectively around the mine. Ventcon controls the mine's fans and ventilation doors so that airflow is highest where most is required. The use of continuous haulage from the face to the surface is another energy-saving development. In many areas of Appalachia, United States, coal is cut by a continuous miner and hauled directly to the surface by a series of conveyors. The use of aluminum in cage and skip manufacturehas also been proven as an energy-saving technique. All-aluminum man cages are already in use. For the tougher application of hoisting coal, aluminum can be substituted for heavier materials in the construction of skips. In both cases, significant energy savings, and thus reduced hoisting costs, are the result. There is a power saving of more than 100 kilowatts (134 horsepower) for every one ton reduction of skip mass. The energy efficiencies of hydraulic rock drills are higher than pneumatic drills.

Application of GIS on forecasting water disaster in coal mines  

SciTech Connect (OSTI)

In many coal mines of China, water disasters occur very frequently. It is the most important problem that water gets inrush into drifts and coal faces, locally known as water gush, during extraction and excavation. Its occurrence is controlled by many factors such as geological, hydrogeological and mining technical conditions, and very difficult to be predicted and prevented by traditional methods. By making use of overlay analysis of Geographic Information System, a multi-factor model can be built to forecast the potential of water gush. This paper introduced the method of establishment of the water disaster forecasting system and forecasting model and two practical successful cases of application in Jiaozuo and Yinzhuang coal mines. The GIS proved helpful for ensuring the safety of coal mines.

GPS-based slope monitoring systems and their applications in transition mining from open-pit to underground  

Science Journals Connector (OSTI)

Combining methods of open-pit and underground mining can yield maximum economic outcomes, while they may also cause large-scaled geological hazards, such as landslides. Failure to prevent landslides in mining areas could result in losses and damages to equipment, surrounding environments, and even human lives. In this paper, we report the application of global positioning system (GPS) for monitoring the Anjialing Coal Mine, the first mine in China that employs the combining methods of open-pit and underground mining. Mine slopes with different inclined angles were monitored and precise data of ground movements were obtained. Mathematic modelling of the subsidence rate over time has successfully detected the occurrence of terminal subsidence rate and a corresponding a landslide. The equipment and persons involved were evacuated and kept safe before the medium landslide occurred. In conclusion, the GPS monitoring system is proved to be effective in mitigating the geological hazards in mining areas.

Marine clathrate mining and sediment separation  

DOE Patents [OSTI]

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.

Detecting Structural Damage of Nuclear Power Plant by Interactive Data Mining Approach  

SciTech Connect (OSTI)

This paper presents a nonlinear structural damage identification technique, based on an interactive data mining approach, which integrates a human cognitive model in a data mining loop. A mining control agent emulating human analysts is developed, which directly interacts with the data miner, analyzing and verifying the output of the data miner and controlling the data mining process. Additionally, an artificial neural network method, which is adopted as a core component of the proposed interactive data mining method, is evolved by adding a novelty detecting and retraining function for handling complicated nuclear power plant quake-proof data. Plant quake-proof testing data has been applied to the system to show the validation of the proposed method. (author)

Geologic factors in coal mines roof stability: a progress report  

SciTech Connect (OSTI)

This report summarizes 10 selected United States Bureau of Mines research contract reports produced from 1970 to 1980 that consist largely of geologic studies of coal-mine roof-support problems. The reports focus on the Appalachian and Illinois coal-mining regions. In the Appalachian region two geologic structures, roof rolls and slickensides, predominate as features that directly contribute to roof falls. Studies of these and other structures are reviewed, and improved methods of utilizing drill core and core logs to prepare hazard maps are presented. Among the reports described are several on the weakening effects of moisture on shale roof, as determined from both laboratory and underground measurements, and an assessment of air tempering as a humidity-control method. Also summarized are findings concerning the time lapse between roof exposure and permanent support installation as a factor in the effectiveness of roof bolting.

Surface mine reclamation for wildlife  

SciTech Connect (OSTI)

This document presents a reclamation plan for use on surface coal mines in southern Appalachia. The plan has been implemented cooperatively by TVA and the FWS on a mine site in Campbell County, Tennessee. Included are suggestions for establishing groundcover and trees on the mine site, and for retaining surface water on mine sites. All techniques discussed are to benefit wildlife and to assist the operator in achieving bond release. Also included is a section on the costs of reclaiming the Campbell County study site to benefit forestry and wildlife. The costs of this project are compared to the costs of reclaiming a more traditional forestry (monoculture) option. The comparison showed the techniques at the study site to be less costly than those that would be associated with a forestry option. 11 references, 14 figures, 2 tables.

Technology experience and economics of oil shale mining in Estonia  

SciTech Connect (OSTI)

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.

Potential highwall use by raptors in coal mine reclamation  

SciTech Connect (OSTI)

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.

Research on the risk forecast model in the coal mine system based on GSPA-Markov  

Science Journals Connector (OSTI)

Safety accidents in the coal mine occurred frequently, that how to reduce them became an important national task, which the hazards identification and the risk forecast work in the coal mine system can solve. In the process of risk forecast in the coal mine system, considering characteristics that system risk is different in different period, the IDO (identification, difference, opposition) change rule of the set pair which has element weight is analyzed, and on the basis of which, the system risk forecast model based on GSPA-MARKOV is put forward. The application example shows that the risk state in the coal mine system is forecasted by the transition probability and the ergodicity in the model, which embodies fully dynamic, predictable and so on , thus it provides a new method to determine the risk state in the coal mine system.

An integrated approach for the prediction of subsidence for coal mining basins  

Science Journals Connector (OSTI)

Abstract In this study, land subsidence caused by underground mining activities was investigated by means of a new subsidence prediction approach (ISP-Tech) which takes into account the most important parameters contributing subsidence development such as coal production methods, depth, mining sequence and other geomechanical characteristics of underground rock strata, etc. ISP-Tech can be applied to operating mines to keep land subsidence under control as well as virgin coal sites to predict surface subsidence prior to mining activities. In the method, geological information gathered from the geographic information system (GIS) and the mining information system (MIS) are utilised to obtain geological cross-sections which are used in finite element models for mesh building. Then, a number of two dimensional finite element modelling analyses are carried out to determine land subsidence occurring due to mining operations. Finally, land subsidence predicted from modelling studies is compared to the GPS and/or differential interferometry synthetic aperture radar (DIn-SAR) measurements. If incompatibility of the results is detected, finite element meshes should be optimised, and then reanalysed to obtain more compatible results. In the study, two different case studies were given as examples of the application of ISP-Tech. Results of the case studies showed that ISP-Tech can successfully be applied to complex mine subsidence problems. The proposed approach gives more accurate results than those obtained from other classical subsidence prediction methods.

Building damage risk assessment on mining terrains in Poland with GIS application  

Science Journals Connector (OSTI)

The aim of the paper was to present an approach to building damage risk assessment on mining induced areas. The presented method was developed in Poland and then adopted in the other European countries. The method shown is based on a comparison between buildings strength and terrain deformation. Prediction principles of the mining terrain deformation and terrain categorization were described in the paper. Moreover a point method for a building strength to mining impact evaluation was discussed. It should be emphasized that the presented method is optimal for densely build-up areas. The authors proposed supporting actually applied method by GIS analyses. As a case study a densely build-up area influenced by an underground mining exploitation of one of the biggest Polish coal mines has been chosen. The application of the presented method supported by GIS on chosen area enables more automated assessment of building damage caused by mining activity. The procedure outlined in this paper may also be satisfactorily applied in the other counties which cope with the problem of building damage risk assessment optimization.

The report provides a better understanding of how these functions impact coal production in terms of time, cost, and safety. Major underground logistics activities are analyzed and include: transportation and personnel, supplies and equipment; transportation of coal and rock; electrical distribution and communications systems; water handling; hydraulics; and ventilation systems. Recommended areas for future research are identified and prioritized.

Semi autonomous mine detection system  

SciTech Connect (OSTI)

CMMAD is a risk reduction effort for the AMDS program. As part of CMMAD, multiple instances of semi autonomous robotic mine detection systems were created. Each instance consists of a robotic vehicle equipped with sensors required for navigation and marking, a countermine sensors and a number of integrated software packages which provide for real time processing of the countermine sensor data as well as integrated control of the robotic vehicle, the sensor actuator and the sensor. These systems were used to investigate critical interest functions (CIF) related to countermine robotic systems. To address the autonomy CIF, the INL developed RIK was extended to allow for interaction with a mine sensor processing code (MSPC). In limited field testing this system performed well in detecting, marking and avoiding both AT and AP mines. Based on the results of the CMMAD investigation we conclude that autonomous robotic mine detection is feasible. In addition, CMMAD contributed critical technical advances with regard to sensing, data processing and sensor manipulation, which will advance the performance of future fieldable systems. As a result, no substantial technical barriers exist which preclude – from an autonomous robotic perspective – the rapid development and deployment of fieldable systems.

Geochemical and hydrogeologic evolution of alkaline discharges from abandoned coal mines  

SciTech Connect (OSTI)

Numerous large flow (> 2,000 l/min), historically (pre-1973) acidic, abandoned underground deep mine discharges in southwestern Pennsylvania are now alkaline in character, with circumneutral pH. Recently measured flow rates are consistent with those measured 25--30 years ago; thus the change in chemistry is not simply due to dilution by increased flows of uncontaminated water through the mines. It is likely that flooding of the mines has decreased the extent of acidity enhancing aerobic conditions, and that decades of weathering have reduced the amount of reactive pyrite. However, the mines continue to yield a sulfate-rich, Fe-contaminated (19--79 ppm) drainage. These highly alkaline discharges (up to 330 ppm as CaCO{sub 3}) are accompanied by large concentrations of sodium (up to 700 ppm) and suggest cation exchange with the associated overburden. To assess the hydrogeological conditions that result in the formation of alkaline Fe-contaminated mine discharges, the authors examined all the major discharges from a single synclinal basin. The northeast-trending Irwin synclinal coal basin encompasses 94 mi{sup 2} and was extensively mined by underground methods during the first half of this century. All major streams that arise within or cross the syncline are polluted by mine drainage that ranges from highly acidic Fe- and Al-contaminated discharges in the northern portion of the syncline to highly alkaline, iron and sulfate-contaminated discharges to the south. The hydrology of the basin is controlled by its southern plunging structure, by outcrops or drainage tunnels on the western arms of the syncline, and by several coal barriers. A first-order hydrogeologic model was constructed to evaluate ground water flow into and through the mine complexes found in the basin. The model integrates the basin geometry with structural and mine barrier components to determine groundwater flow paths and estimate residence time. Water quality is related to the cumulative proportion of up-gradient flooded and unflooded mine workings. Small discharges from unflooded, gravity-flow portions of the mined-out portion of the Pittsburgh Coal seam are highly acidic, and large artesian flows of water affected by only a short flow through flooded anoxic mine pools are moderately acidic. Those discharges subjected to increased residence time in flooded anoxic portions of the mines are increasingly alkaline. Refinement of this model could aid in prediction and hydrogeologic manipulation of these high flow Fe-contaminated discharges that are the main pollutant in many streams throughout Northern Appalachia and other coal mining areas throughout the world.

Adaptive Model-Based Mine Detection/Localization using Noisy Laser Doppler Vibration Measurements  

SciTech Connect (OSTI)

The acoustic detection of buried mines is hampered by the fact that at the frequencies required for obtaining useful penetration, the energy is quickly absorbed by the ground. A recent approach which avoids this problem, is to excite the ground with a high-level low frequency sound, which excites low frequency resonances in the mine. These resonances cause a low-level vibration on the surface which can be detected by a Laser Doppler Vibrometer. This paper presents a method of quickly and efficiently detecting these vibrations by sensing a change in the statistics of the signal when the mine is present. Results based on real data are shown.

INTEGRATED ROBOT-HUMAN CONTROL IN MINING OPERATIONS  

SciTech Connect (OSTI)

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.

Restoring Sustainable Forests on Appalachian Mined Lands for Wood Products, Renewable Energy, Carbon Sequestration, and Other Ecosystems Services  

SciTech Connect (OSTI)

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. During this quarter we worked on methodologies for analyzing carbon in mine soils. A unique property of mine soils is the presence of coal and carboniferous rock particles that are present in mine soils in various sizes, quantities, and qualities. There is no existing method in the literature that may be of use for quantitative estimation of soil organic carbon (SOC) in mine soils that can successfully differentiate between pedogenic and geogenic carbon forms. In this report we present a detailed description of a 16-step method for measuring SOC in mine soils designed for and tested on a total of 30 different mine soil mixtures representing a wide spectrum of mine soils in the hard-rock region of the Appalachian coalfield. The proposed method is a combination of chemical procedure for carbonates removal, a thermal procedure for pedogenic C removal, and elemental C analysis procedure at 900 C. Our methodology provides a means to correct for the carbon loss from the more volatile constituents of coal fragments in the mine soil samples and another correction factor for the protected organic matter that can also remain unoxidized following thermal pretreatment. The correction factors for coal and soil material-specific SOM were based on carbon content loss from coal and SOM determined by a parallel thermal oxidation analysis of pure ground coal fragments retrieved from the same mined site as the soil samples and of coal-free soil rock fragments of sandstone and siltstone origin.

Economic monitoring of a contour surface mine in steep slope Appalachian topography  

SciTech Connect (OSTI)

Accurate estimates of the costs of various surface mining unit operations in steep Appalachian topography are seldom encountered, but are essential to assessment of the feasibility of improving mined land reclamation via Controlled Overburden Placement (COP) procedures. The purposes and methods of monitoring economic costs and overburden movement at a steeply sloping Appalachian contour surface mine in Wise County, Virginia, are discussed. The monitoring program consists of three phases: daily records of machinery operation, monthly site visits to record mining progress, and studies of unit operations at the Amos Ridge site and at other sites in the area. The monitoring program is designed to allow precise estimates to be made of the machine hours required to move and place defined amounts of overburden under specified conditions. Limitations to the accuracy of such estimates are detailed. Accurate economic information on various mining procedures will facilitate the evaluation of tradeoffs between costs and environmental effects, as is necessary to make effective public policy decisions which affect mine reclamation practice.

Australian coal mine methane emissions mitigation potential using a Stirling engine-based CHP system  

Science Journals Connector (OSTI)

Abstract Methane, a major contributor to global warming, is a greenhouse gas emitted from coal mines. Abundance of coal mines and consequently a considerable amount of methane emission requires drastic measures to mitigate harmful effects of coal mining on the environment. One of the commonly adopted methods is to use emitted methane to fuel power generation systems; however, instability of fuel sources hinders the development of systems using conventional prime movers. To address this, application of Stirling engines may be considered. Here, we develop a techno-economic methodology for conducting an optimisation-based feasibility study on the application of Stirling engines as the prime movers of coal mine CHP systems from an economic and an environmental point of view. To examine the impact of environmental policies on the economics of the system, the two commonly implemented ones (i.e. a carbon tax and emissions trading scheme) are considered. The methodology was applied to a local coal mine. The results indicate that incorporating the modelled system not only leads to a substantial reduction in greenhouse gas emissions, but also to improved economics. Further, due to the heavy economic burden, the carbon tax scheme creates great incentive for coal mine industry to address the methane emissions.

Power load forecasting using data mining and knowledge discovery technology  

Science Journals Connector (OSTI)

Considering the importance of the peak load to the dispatching and management of the electric system, the error of peak load is proposed in this paper as criteria to evaluate the effect of the forecasting model. This paper proposes a systemic framework that attempts to use data mining and knowledge discovery (DMKD) to pretreat the data. And a new model is proposed which combines artificial neural networks with data mining and knowledge discovery for electric load forecasting. With DMKD technology, the system not only could mine the historical daily loading which had the same meteorological category as the forecasting day to compose data sequence with highly similar meteorological features, but also could eliminate the redundant influential factors. Then an artificial neural network is constructed to predict according to its characteristics. Using this new model, it could eliminate the redundant information, accelerate the training speed of neural network and improve the stability of the convergence. Compared with single BP neural network, this new method can achieve greater forecasting accuracy.

Bees swarm optimisation using multiple strategies for association rule mining  

Science Journals Connector (OSTI)

Association rules mining has been largely studied by the data mining community. ARM aims to extract the interesting rules from any given transactional database. This problem is well known to be time consuming in general. This paper deals with association rules mining algorithms to cope with very large databases and especially for those existing on the web. Many polynomial exact algorithms already proposed in literature have shown their efficiency when dealing with small and medium datasets. Unfortunately, their efficiency is not enough for handling the huge amount of data in the web context requiring a real time response. Not surprisingly, some bio-inspired methods seem to be clearly more appropriate. This paper mainly proposes a new ARM algorithm based on an improved version of bees swarm optimisation with three different heuristics for exploring the search area. This approach has been implemented and experimented on different dataset benchmarks with small size, medium size and large size. These first empirical results highlighted that our approach outperforms some other existing algorithms both in terms of fitness criterion and CPU time.

NOVEL EXCAVATION TECHNOLOGIES FOR EFFICIENT AND ECONOMIC SURFACE MINING  

SciTech Connect (OSTI)

Ground excavation constitutes a significant component of production costs in any surface mining operation. The excavation process entails material digging and removal in which the equipment motion is constrained by the workspace geometry. A major excavation problem is the variability of material properties, resulting in varying mechanical energy input and stress loading of shovel dipper-and-tooth assembly across the working bench. This variability has a huge impact on the shovel dipper and tooth assembly in hard formations. With this in mind, the primary objectives of the project were to (i) provide the theoretical basis to develop the Intelligent Shovel Excavation (ISE) technology to solve the problems associated with excavation in material formations; (ii) advance knowledge and frontiers in shovel excavation through intelligent navigation; and (iii) submit proposal for the design, development and implementation of the ISE technology for shovel excavation at experimental surface mining sites. The mathematical methods were used to (i) develop shovel's kinematics and dynamics, and (ii) establish the relationship between shovel parameters and the resistive forces from the material formation during excavation process. The ADAMS simulation environment was used to develop the hydraulic and cable shovel virtual prototypes. Two numerical examples are included to test the theoretical hypotheses and the obtained results are discussed. The area of sensor technology was studied. Application of specific wrist-mounted sensors to characterize the material, bucket and frame assembly was determined. Data acquisition, display and control system for shovel loading technology was adopted. The concept of data acquisition and control system was designed and a shovel boom stresses were simulated. A multi-partner collaboration between research organizations, shovel manufacturer, hardware and sensor technology companies, and surface mining companies is proposed to test design features, construct a field ready prototype and perform field testing at the surface mining sites. It is anticipated that 10% in energy savings including electricity (cable shovel) and fuel (hydraulic shovel) will be achieved by implementation of ISE technology.

Encouraging re-mining and reclamation of abandoned mined lands in Appalachia: Policy options  

SciTech Connect (OSTI)

Abandoned mined lands (AML) are areas that were mined prior to implementation of federal controls over coal-mined land reclamation and were inadequately reclaimed. The majority of the US`s AML acreages were produced by coal mining in the Appalachian areas. Environmental problems include lands in barren or semi-barren condition, excessive sedimentation, acid water discharges, and unstable slopes. This article address the potential to reclame AMLs in the Appalachian region by creating incentives for environmental enhancement through re-mining. Background information of AML and on current policies affecting re-mining are reviewed and the results of a survey of individuals who are knowledgeable in remining policy issues are reported. 7 refs., 3 figs., 3 tabs.

Probable hydrologic effects of subsurface mining  

SciTech Connect (OSTI)

This case history provides information on the ground-water system and presents the results of an analysis of present and future hydrologic effects of coal mining in the Appalachian coal basin. Although emphasis is on the probable hydrologic effects due to subsurface mining, examples and discussions are equally applicable to surface mine problems. The case history is based on an ongoing study in Greene County which will be completed in 1983. Cooperators in this project were the Pennsylvania Geologic and Topographic Survey and the Greene County Commissioners. The study stemmed from local interest in the rural water supply of the county which is predominantly groundwater.

HV Substation Earthing Design for Mines  

E-Print Network [OSTI]

Abstract:-High Voltage (HV) substation forms important assets for the mining industries. The existences of these substations necessitate earthing design to ensure safety compliance to the mine regulations. The HV system within the mines is consisted of multiple substations which are connected throughout and underground cable. These substations provide the load with the required electrical power to perform its tasks. This paper endeavours to provide information in regards to the different types of connections between the load and the substations (TT, TN and IT Systems). Furthermore, the earthing arrangements under different connection were assessed. A case study is addressed to show the different earthing arrangements under different connection systems Keywords:- Earth Grid, EPR, Fault Current, High Voltage, Mines, TN and TT systems I.

Fuelcell-Hybrid Mine loader (LHD)  

SciTech Connect (OSTI)

The fuel cell hybrid mine loader project, sponsored by a government-industry consortium, was implemented to determine the viability of proton exchange membrane (PEM) fuel cells in underground mining applications. The Department of Energy (DOE) sponsored this project with cost-share support from industry. The project had three main goals: (1) to develop a mine loader powered by a fuel cell, (2) to develop associated metal-hydride storage and refueling systems, and (3) to demonstrate the fuel cell hybrid loader in an underground mine in Nevada. The investigation of a zero-emissions fuel cell power plant, the safe storage of hydrogen, worker health advantages (over the negative health effects associated with exposure to diesel emissions), and lower operating costs are all key objectives for this project.

Combining data mining and machine learning for effective user profiling  

SciTech Connect (OSTI)

This paper describes the automatic design of methods for detecting fraudulent behavior. Much of the design is accomplished using a series of machine learning methods. In particular, we combine data mining and constructive induction with more standard machine learning techniques to design methods for detecting fraudulent usage of cellular telephones based on profiling customer behavior. Specifically, we use a rule-learning program to uncover indicators of fraudulent behavior from a large database of cellular calls. These indicators are used to create profilers, which then serve as features to a system that combines evidence from multiple profilers to generate high-confidence alarms. Experiments indicate that this automatic approach performs nearly as well as the best hand-tuned methods for detecting fraud.

Drilling and blasting techniques and costs for strip mines in Appalachia  

SciTech Connect (OSTI)

On-site investigations of blasting techniques were conducted at twenty surface coal mining operations in the steep slopes of Appalachia. The mine sites represented a range of mountain mining methods and annual coal production levels; all sites used similar techniques and equipment for the removal of fragmented waste rock. Hole loading characteristics and constraints limiting blast designs were observed at each mine site. This report summarizes technical blasting data and geological conditions which require special design considerations. Three mine sites were selected for future research in fragmentation efficiency. Detailed economic data on drilling and blasting were gathered from the three research sites and are reported herein. A great deal of fragmentation difficulties stem from tough, unpredictable geology with specific bedding characteristics and local zones of defined structural weaknesses such as jointing and vertical seams. Exceptionally hard bedrock, existing as a caprock or as the basal layer above the coal seam, persists as the cause of oversize rock breakage or, in the latter case, damage to the coal unless special precautions are taken. Federal blasting regulations strictly control the amount of explosives used as well as throw of the fragmented rock. This requires that blasting modifications be employed. The nature and extent of blast modifications were observed to be related to terrain and demographic conditions around the mine site. Drilling and blasting costs reported for the three mine sites averaged $0.21 per cubic yard of material blasted. Drilling costs varied widely, as drilling time was indicative of geologies and often, drilling costs remained the greatest percentage of total blasting and drilling costs.

Regulating for the long term: SMCRA and acid mine drainage  

SciTech Connect (OSTI)

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.

Higher coronary heart disease and heart attack morbidity in Appalachian coal mining regions  

Science Journals Connector (OSTI)

Background This study analyzes the U.S. 2006 Behavioral Risk Factor Surveillance System survey data (N = 235,783) to test whether self-reported cardiovascular disease rates are higher in Appalachian coal mining counties compared to other counties after control for other risks. Methods Dependent variables include self-reported measures of ever (1) being diagnosed with cardiovascular disease (CVD) or with a specific form of CVD including (2) stroke, (3) heart attack, or (4) angina or coronary heart disease (CHD). Independent variables included coal mining, smoking, BMI, drinking, physician supply, diabetes co-morbidity, age, race/ethnicity, education, income, and others. SUDAAN Multilog models were estimated, and odds ratios tested for coal mining effects. Results After control for covariates, people in Appalachian coal mining areas reported significantly higher risk of CVD (OR = 1.22, 95% CI = 1.14–1.30), angina or CHD (OR = 1.29, 95% CI = 1.19–1.39) and heart attack (OR = 1.19, 95% CI = 1.10–1.30). Effects were present for both men and women. Conclusions Cardiovascular diseases have been linked to both air and water contamination in ways consistent with toxicants found in coal and coal processing. Future research is indicated to assess air and water quality in coal mining communities in Appalachia, with corresponding environmental programs and standards established as indicated.

Could a public ecology approach help resolve the mountaintop mining controversy?  

Science Journals Connector (OSTI)

In recent years, controversy has grown around decisions related to mountaintop removal mining of coal in Central Appalachia, USA. While this mining method can be particularly efficient, it necessitates removal and relocation of huge volumes of earth—permanently altering the natural landform and potentially impacting local environments and communities. Current decision-making systems and regulatory frameworks have been largely ineffective at incorporating the values and concerns of stakeholders. This is due, in part, to contradicting policies, a legacy of distrust, and problems related to scale. Further, the lack of good civic science related to mountaintop mining and meaningful routes for public involvement have also hampered effective decision-making. We propose that the fundamental concepts of public ecology may provide a progressive approach to resolving these complex issues, and examine the challenges that must be met along the way.

Underground Mine Water Heating and Cooling Using Geothermal Heat Pump Systems  

SciTech Connect (OSTI)

In many regions of the world, flooded mines are a potentially cost-effective option for heating and cooling using geothermal heat pump systems. For example, a single coal seam in Pennsylvania, West Virginia, and Ohio contains 5.1 x 1012 L of water. The growing volume of water discharging from this one coal seam totals 380,000 L/min, which could theoretically heat and cool 20,000 homes. Using the water stored in the mines would conservatively extend this option to an order of magnitude more sites. Based on current energy prices, geothermal heat pump systems using mine water could reduce annual costs for heating by 67% and cooling by 50% over conventional methods (natural gas or heating oil and standard air conditioning).

Two and three dimensional analysis of a slope failure in a lignite mine  

Science Journals Connector (OSTI)

With about 9.3 billion tons of reserve, lignite is a major source for energy production in Turkey. The Af?in–Elbistan lignite basin, containing 47% of the overall lignite reserve in Turkey, lies in the Af?in and Elbistan districts as a part of Kahramanmara?. The new Çöllolar opencast mine is in the Afsin–Elbistan lignite basin, and this mine will be the second mining activity in the basin after the active K??laköy opencast mine. The new mine will meet the coal consumption of the Elbistan B power plant. Input parameters for slope stability analysis are essential, and so they must be determined accurately and precisely. Field investigations, laboratory testing and back analyses are vital instruments for the input parameters. This study presents the results of slope stability analysis via finite difference code and a limit equilibrium software for the soil slopes of the Elbistan–Çöllolar lignite mine. The basic input parameters, cohesion and friction angle, were determined in the soil mechanics laboratory. By back analyses of a large scale slope failure, mobilized friction angles for a critical weak clay layer under the lignite seam were determined accurately by using the 2D limit equilibrium method and 3D finite difference models. Results of the friction angles were compared in order to check the effectiveness of commonly used 2D approaches in handling the slope problems. Differences in the results of the mobilized friction angles for the weak clay layer were more than 30%. The 3D models indicated that the mobilized friction angle during the major slope failure was substantially lower than the friction angle generated by the 2D limit equilibrium method.

Surface mining environmental monitoring and reclamation handbook  

SciTech Connect (OSTI)

The Surface Mining Environmental Monitoring and Reclamation Handbook has been expressly designed to meet the statutory requirements of surface coal mining and reclamation. It sets forth a range of monitoring techniques in a manner that is most likely to be of direct, practical, and cost-effective use to the widest expanse of mining-reclamation situations. A literature review identifies and evaluates those published sources of information that are most applicable to the needs of handbook users. This is supplemented by identifying other sources of pertinent information with particular attention paid to local, state, and federal agencies that can supply data required for mining and reclamation efforts. Attention is then directed toward the means whereby regulatory requirements can be satisfied. An effort has been made to identify those areas likely to present special problems. And, finally, where appropriate, modeling techniques are described and the extent of their utility delineated. Throughout, the handbook has maintained a practical focus. It attempts to provide surface coal mine operators with the tools and techniques needed to meet legal environmental and monitoring requirements without an unnecessary and costly overexpenditure of time and money. The provision of a range of alternatives to meet various obligations, the stress on using existing resources whenever possible, and the careful differentiation of means and ends are all directed toward the best ways to meet regulatory requirements.

Noise exposures in US coal mines  

SciTech Connect (OSTI)

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.

Restoration of surface-mined lands with rainfall harvesting  

SciTech Connect (OSTI)

Strip mining for coal in the arid western US will remove grazing land as energy demands are met. Conventional resotration usually includes leveling the spoil banks and covering them with top soil, fertilizing, seeding and irrigation with well or river water. An overview of research on an alternate method of restoring this land is reported. From 1976 through 1981 studies were conducted on the use of water harvesting, the collection and use of rainfall runoff, to restore the vegetative productivity of strip mined lands in arid regions. These studies tested the technical and economic feasibility of using partially leveled spoil banks at strip mines as catchment areas to collect and direct runoff to the topsoiled valley floor where crops were cultivated. Information was collected on the efficiency of seven treatments to increase runoff from the catchment areas and on the productivity of seven crops. The experiments were conducted in arid areas of Washington, Arizona, and Colorado. It was concluded that water harvesting can replace or augment expensive and inadequate supplies of well and river water in arid regions with a suitable climate. These studies showed that some treatments provided adequate runoff to produce a useful crop in the valleys, thus making this alternative approach to restoration technically feasible. This approach was also potentially economically feasible where the treatment costs of the catchment areas were low, the treatment was effective, the crop was productive and valuable, and earthmoving costs were lower than with conventional restoration involving complete leveling of spoil banks. It was also concluded that water harvesting can be made more effective with further information on catchment area treatments, which crops are most adaptable to water harvesting, the optimum incline of the catchment areas and climatic influences on water harvesting.

Reduction of fire hazards on large mining equipment  

SciTech Connect (OSTI)

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.

Development of surface mine cost estimating equations  

SciTech Connect (OSTI)

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.

IN-SITU MINING OF PHOSPHATE ORES  

SciTech Connect (OSTI)

Presently the mining of Florida phosphate requires the movement of over a 100-ton of materials (overburden, sand, clay) for every ton of phosphate concentrate recovered. Not only is this energy intensive, but it also causes significant stress on the environment. In 2003, the Department of Energy solicited ideas for innovative mining ideas that could significantly improve the efficiency of mining. An award was made to the University of Florida Engineering Research Center to evaluate the in situ mining of phosphates using an aqueous CO{sub 2} solution. Tests were carried out in a 15.2 cm (6-inch) diameter column, 1.83 meter (6 feet) long at pressures up to 117.2 kg/cm{sup 2} (40 psi). Results to date demonstrate that initially the MgO is leached from the ore and then the phosphate. While the tests are continuing, so far they have not demonstrated P{sub 2}O{sub 5} concentrations that are economically attractive.

Selective mining and beneficiation at Grootegeluk coal mine Waterberg Coalfield, South Africa  

SciTech Connect (OSTI)

Grootegeluk Coal Mine, situated in the Waterberg Coalfield in the Northern Province of South Africa, ranks among the largest open pit coal mines in the world in terms of run of mine tonnage. Commissioned in 1980 to provide steel producer Iscor with coking coal, Grootegeluk currently produces 53 Mt of coking coal per annum. At present Iscor consumes 1.2 Mt of coking coal while Matimba, the world's largest direct dry cooled PowerStation consumes an additional 12.6 Mt. Fine washing and screening plants currently beneficiate the run of mine feed from this multi-seam multi-product mine. Although the Waterberg Coalfield contains approximately 50% of South Africa's coal reserves, Grootegeluk is the only operating mine in this coalfield. The coal seams of the Waterberg Coalfield occur in the Volksrust and Vryheids formations of the Karoo Sequence. Numerous coal seams ranging from a few millimeters up to 8 meters occur over a stratigraphic thickness of at least 120 meters. These coal seams are grouped into eleven coal bearing zones that can be correlated across the coalfield. The coal- and coalbearing strata in the Waterberg are of late Paleozoic to early Mesozoic age. Coal from the Volksrust formation is autochthonous while the coal from the Vryheid formation is allochthonous. To ensure that sufficient geological and analytical data are obtained from exploration boreholes an extensive sampling procedure was established with washability data ranging from 1,35 to 2,20 g/cc. The analyses indicated that certain parts of the coalbearing strata is not suitable for the production of coking coal due to the high phosphorus content or the poor coking properties. This resulted in an open pit with 11 mining benches. The upper parts of the deposit is extracted by conventional shovel and truck operations while the coal seams of the lower part of the deposit are mined selectively with hydraulic shovels. At Grootegeluk down the hole geophysics (natural gamma) are used for grade control and also to quantify the effect of over- or undermining on the various mining benches. Reconciliation between the run of mine material dispatched to the various plants and their resulted yields/qualities are done regularly.

Geologic factors in coal mine roof stability--a progress report. Information circular/1984. [Effects of moisture  

SciTech Connect (OSTI)

This report summarizes 10 selected Bureau of Mines research contract reports produced from 1970 to 1980 which consist largely of geologic studies of coal mine roof support problems. Significant highlights from the contract final reports are discussed and presented in practical terms. The selected reports focus on the Appalachian and Illinois coal mining regions. In the Appalachian coal region, two geologic structures, roof rolls and slickensides, predominate over all structures as features that directly contribute to roof falls. Studies of these and other structures are reviewed, and improved methods of utilizing drill core and core logs to prepare hazard maps are presented. Among the reports described are several on the weakening effects of moisture on shale roof, as determined from both laboratory and underground measurements, and an assessment of air tempering as a humidity-control method. Also summarized are findings concerning the time lapse between roof exposure and permanent support installation as a factor in the effectiveness of roof bolting.

Fecal coliform concentrations in runoff from a grazed, reclaimed surface mine  

SciTech Connect (OSTI)

The relatively scarcity of flat or moderately sloping land in Central Appalachia make reclaimed surface mined lands attractive for agricultural uses. A reclaimed surface coal mine in southern West Virginia was placed under grazing management during the 1984 and 1985 grown seasons. Discharge was collected from summer-grazed watersheds of about 2.8 ha and 8.9 ha and analyzed, by the membrane-filtration method, for fecal coliforms (FC). Prior to grazing in 1984, FC counts were < 200/100 ml. During the grazing season, FC ranged from < 0/100 ml to > 1000/100 ml in 1984 and from 0/100 ml to > 2500/100 ml in 1985. FC counts remained high during warm periods for several months after grazing ceased. It was concluded that the bacteriological quality of receiving streams was impacted by grazing the reclaimed area and recommended standards for point sources were often exceeded; however, the FC counts did not appear to be any greater than what would have been expected from grazed, undisturbed areas. Reclaimed surface mines areas in Appalachia have the potential to be a valuable flat land resource and grazing appears to be an alternative post mine land use that affects bacteriological water quality in a similar manner as natural pastures. However, good management practices may be necessary to avoid bacterial contamination of adjacent bodies of water.

Hazard recognition and adjustment in northern Appalachia: examples of coal-mine subsidence in small communities  

SciTech Connect (OSTI)

Mine subsidence is a pervasive hazard in the northern Appalachian coal fields and is associated with both active and abandoned mines. Causative factors include the method of mining, geological and hydrologic conditions, and surface activities. Its economic costs include surface property damages and depreciations plus costs of mitigation. Environmental impacts include derangement of surface drainage and loss of aquifer. These topics are reviewed here, and on subsidence cognition and the research findings are discussed. One bituminous and three anthracite area boroughs in Pennsylvania served as case studies. Local officials and planners were informally interviewed and surveys of residents conducted. The present study differs from most in the traditional hazard-perception genus in several ways. It addresses the salience of hazard amid other pressing community concerns. Salience, rather than perceived seriousness, provides greater insights into residents' coping responses. Consideration is given to institutional and other contextual influences on individuals' adjustment strategies. Finally, coal mine subsidence is a technological hazard, albeit one which is geological in character.

DISPOSAL OF FLUIDIZED BED COMBUSTION ASH IN AN UNDERGROUND MINE TO CONTROL ACID MINE DRAINAGE AND SUBSIDENCE  

SciTech Connect (OSTI)

This project evaluated the technical, economic and environmental feasibility of filling abandoned underground mine voids with coal combustion byproducts. 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.

Capture and Use of Coal Mine Ventilation-Air Methane  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Capture and use of Coal Mine Capture and use of Coal Mine Ventilation - air Methane Background Methane emissions from coal mines represent about 10 percent of the U.S. anthropogenic methane released to the atmosphere. Methane-the second most important non-water greenhouse gas-is 21 times as powerful as carbon dioxide (CO 2 ) in its global warming potential. Ventilation-air methane (VAM)-the exhaust air from underground coal mines-is the largest source of coal mine methane, accounting for about half of the methane emitted from coal mines in the United States. Unfortunately, because of the low methane concentration (0.3-1.5 percent) in ventilation air, its beneficial use is difficult. However, oxidizing the methane to CO 2 and water reduces its global warming potential by 87 percent. A thermal

Prospects for Universal Heat Mining: from a Jules Verne vision to a 21st century reality  

SciTech Connect (OSTI)

The extraction of heat or thermal energy from the Earth -- heat mining -- has the potential to play a major role as an energy supply technology for the 21st century. However, even if reservoir stimulation goals are achieved, the role of heat mining with today's energy prices and development costs is limited to only a small fraction of the earth's surface, specifically to geologically active regions where geothermal gradients are high. This paper examines the prospects for universal heat mining and the types of developments required to make it a reality. A generalized multi-parameter economic model was developed for optimizing the design and performance of hot dry rock (HDR) geothermal systems by linking an SQP nonlinear programming algorithm with a generalized HDR economic model. HDR system design parameters selected for optimization include well depth (or initial rock temperature), geofluid flow rate, number of fractures and injection temperature. The sensitivities of the optimized design parameters, HDR system performance, and levelized electricity price to average geothermal gradient, fractured area/volume, maximum allowable geofluid temperature, reservoir flow impedance, well deviation, and fracture separation have been investigated. Key technical and institutional obstacles to universal heat mining are discussed in a more general context. These include (1) developing methods for stimulating low permeability formations to provide sustained productivity with acceptable flow/pressure losses (2) dealing with barriers to change primary energy supply options when fossil energy resources are abundant and prices are low and (3) lowering the high drilling costs for developing the deep (>5 km) reservoirs required in low gradient areas. Advanced concepts in drilling technology that could lead to a linear as opposed to exponential relationship between cost and depth are discussed in light of their potential impact on heat mining.

Land reclamation and strip-mined coal production in appalachia  

Science Journals Connector (OSTI)

This study quantifies the short-run impacts of reclamation on strip mining costs, coal prices, production, and employment in Appalachia. A process analysis model is developed and used to estimate short-run strip-mined coal supply functions under conditions of alternative reclamation requirements. Then, an econometric model is developed and used to estimate coal demand relations. Our results show that full reclamation has rather minor impacts. In 1972, full reclamation would have increased strip-mined coal production costs an average of $0.35 per ton, reduced strip-mined coal production by 10 million tons, and cost approximately 1600 jobs in Appalachia.

Sugarbush system: a post-mining land use alternative  

SciTech Connect (OSTI)

Viable, potentially-profitable, post-mining options for high elevation sites in the Appalachian coal fields are limited. Sugar maple groves designed for long term profitable system operation seems to be one such option. This is a design document for a sugarbush system with equations for optimizing the system, subject to local constraints. Mine land reclamation specialists may consider and explore options using an available computer program (IBM-PC BASIC). Creating a sugarbush may suggest the long term interest of some mined-land owners in their land and it may represent an acceptable post-mining alternative on some sites to conventional reclamation practices. 20 references, 2 figures, 2 tables.

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

SciTech Connect (OSTI)

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.

Accurate and direct quantification of native brucite in serpentine ores—New methodology and implications for CO2 sequestration by mining residues  

Science Journals Connector (OSTI)

Abstract An original method was developed to accurately quantify brucite content in mining residues whereby the thermal decomposition of pure brucite, olivine, serpentine and mining residues was comprehensively studied. The simultaneous dehydroxylation of brucite and various serpentine minerals was investigated using a combination of isothermal and nonisothermal thermogravimetric analyses with mass spectrometry. The dehydroxylation rate of brucite was highly influenced by its particle size distribution. However, the technique proposed here revealed similar particle size distributions of native brucite irrespective of the analyzed mining residue samples. This suggests the technique could also be extended to coarse mining residue particle samples containing invariant brucite size distributions. Native brucite dehydroxylation was shown to start at lower temperatures than serpentines. The weight loss due to dehydroxylation registered for brucite-doped olivine and residues revealed a quasi-linear correlation with brucite content (R2 = 1) and provided a reliable and straightforward approach for the quantification of free brucite in single minerals as well as in mining residues. The accuracy was higher than most of the current techniques used for brucite quantification. The uncertainties were as low as ?0.05 wt% for mining residues and ?0.02 wt% for single minerals rendering this method a promising tool for native brucite quantification.

Inflatable partition for fighting mine fires  

DOE Patents [OSTI]

The seal is a lightweight, inflatable, bag which may be inflated by a portable air generator and is used to seal a burning mine passage. A collapsible tube-like aperture extends through the seal and allows passage of high expansion foam through the seal in a feed tube. The foam fills the passageway and extinguishes the fire. In other embodiments, the feed tubes incorporate means to prevent collapse of the aperture. In these embodiments a shroud connects the feed tube to a foam generator. This seal allows creation of a high expansion foam fire fighting barrier even in upward sloping passages.

Underground physics without underground labs: large detectors in solution-mined salt caverns  

E-Print Network [OSTI]

A number of current physics topics, including long-baseline neutrino physics, proton decay searches, and supernova neutrino searches, hope to someday construct huge (50 kiloton to megaton) particle detectors in shielded, underground sites. With today's practices, this requires the costly excavation and stabilization of large rooms in mines. In this paper, we propose utilizing the caverns created by the solution mining of salt. The challenge is that such caverns must be filled with pressurized fluid and do not admit human access. We sketch some possible methods of installing familiar detector technologies in a salt cavern under these constraints. Some of the detectors discussed are also suitable for deep-sea experiments, discussed briefly. These sketches appear challenging but feasible, and appear to force few major compromises on detector capabilities. This scheme offers avenues for enormous cost savings on future detector megaprojects.

A reclamation approach for mined prime farmland by adding organic wastes and lime to the subsoil  

SciTech Connect (OSTI)

Surface mined prime farmland may be reclaimed by adding organic wastes and lime to subsoil thus improving conditions in root zone. In this study, sewage sludge, poultry manure, horse bedding, and lime were applied to subsoil (15-30 cm) during reclamation. Soil properties and plant growth were measured over two years. All organic amendments tended to lower the subsoil bulk density and increase organic matter and total nitrogen. Liming raised exchangeable calcium, slightly increased pH, but decreased exchangeable magnesium and potassium. Corn ear-leaf and forage tissue nitrogen, yields, and nitrogen removal increased in treatments amended with sewage sludge and poultry manure, but not horse bedding. Subsoil application of sewage sludge or poultry manure seems like a promising method in the reclamation of surface mined prime farmland based on the improvements observed in the root zone environment.

Mining API Error-Handling Specifications from Source Code  

E-Print Network [OSTI]

Abstract. API error-handling specifications are often not documented, necessitating automated specification mining. Automated mining of error-handling specifications is challenging for procedural languages such as C, which lack explicit exception-handling mechanisms. Due to the lack of explicit exception handling, error-handling code is often scattered across different procedures and files making it difficult to mine error-handling specifications through manual inspection of source code. In this paper, we present a novel framework for mining API errorhandling specifications automatically from API client code, without any user input. In our framework, we adapt a trace generation technique to distinguish and generate static traces representing different API run-time behaviors. We apply data mining techniques on the static traces to mine specifications that define correct handling of API errors. We then use the mined specifications to detect API error-handling violations. Our framework mines 62 error-handling specifications and detects 264 real error-handling defects from the analyzed open source packages. 1 1

Economic environment of coal mining operations in Appalachia, United States  

Science Journals Connector (OSTI)

Appalachia is a mountainous coal region, in the United States, where the small mining operation dominates. The large number of small coal operations makes the coal industry in that area very competitive, the industry concentration ratio being low. The vast majority of the small coal operations are contractors and nonunionized. There are various circumstances under which a large company will elect to supplement their coal production from their, usually larger, coal mines. The size of the coal mine is generally dictated by the size and location of the coal reserves. The optimum rate of coal extraction, and hence the life of the mine, is a factor of the size of the coal reserves and the contribution margin (coal price less variable cost). Large companies tend to have better safety records than smaller companies due to greater numbers of professional engineers and better management. Small mines have the advantage of closer supervision.

Geologic considerations in underground coal mining system design  

SciTech Connect (OSTI)

Geologic characteristics of coal resources which may impact new extraction technologies are identified and described to aid system designers and planners in their task of designing advanced coal extraction systems for the central Appalachian region. These geologic conditions are then organized into a matrix identified as the baseline mine concept. A sample region, eastern Kentucky, is next analyzed, using both the new baseline mine concept and traditional geologic investigative approach. The baseline mine concept presented is intended as a framework, providing a consistent basis for further analyses to be subsequently conducted in other geographic regions. The baseline mine concept is intended as a tool to give system designers a more realistic feel of the mine environment and will hopefully lead to acceptable alternatives for advanced coal extraction system.

JGI - Why Sequence Euryarchaeota in Acid Mine Drainage?  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Euryarchaeota in Acid Mine Drainage? Euryarchaeota in Acid Mine Drainage? Acid mine drainage (AMD) is a major worldwide environmental problem associated with the mining of energy resources (coal and uranium) and metals (eg., iron and copper), thus of direct DOE relevance. The processes that underpin AMD formation can be harnessed for bioleaching and bioremediation. Many scientific and industrial groups are studying various aspects of the biogeochemistry of AMD generation. Random shotgun sequencing of an extremely acidic (pH <0.9) chemolithotrophic subsurface AMD biofilm community (from the Richmond Mine in Iron Mountain, California) recovered a genome fragment from a novel euryarchaeon, named WTF-1. This novel lineage was previously missed by common broad-specificity primers used for PCR-based surveys. Further study

Aquatic Ecosystem Enhancement at Mountaintop Mining Sites Symposium  

SciTech Connect (OSTI)

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.

Application of decision tree model for the ground subsidence hazard mapping near abandoned underground coal mines  

Science Journals Connector (OSTI)

Abstract Subsidence of ground caused by underground mines poses hazards to human life and property. This study analyzed the hazard to ground subsidence using factors that can affect ground subsidence and a decision tree approach in a geographic information system (GIS). The study area was Taebaek, Gangwon-do, Korea, where many abandoned underground coal mines exist. Spatial data, topography, geology, and various ground-engineering data for the subsidence area were collected and compiled in a database for mapping ground-subsidence hazard (GSH). The subsidence area was randomly split 50/50 for training and validation of the models. A data-mining classification technique was applied to the GSH mapping, and decision trees were constructed using the chi-squared automatic interaction detector (CHAID) and the quick, unbiased, and efficient statistical tree (QUEST) algorithms. The frequency ratio model was also applied to the GSH mapping for comparing with probabilistic model. The resulting GSH maps were validated using area-under-the-curve (AUC) analysis with the subsidence area data that had not been used for training the model. The highest accuracy was achieved by the decision tree model using CHAID algorithm (94.01%) comparing with QUEST algorithms (90.37%) and frequency ratio model (86.70%). These accuracies are higher than previously reported results for decision tree. Decision tree methods can therefore be used efficiently for GSH analysis and might be widely used for prediction of various spatial events.

US uranium mining industry: background information on economics and emissions  

SciTech Connect (OSTI)

A review of the US uranium mining industry has revealed a generally depressed industry situation. The 1982 U/sub 3/O/sub 8/ production from both open-pit and underground mines declined to 3800 and 6300 tons respectively with the underground portion representing 46% of total production. US exploration and development has continued downward in 1982. Employment in the mining and milling sectors has dropped 31% and 17% respectively in 1982. Representative forecasts were developed for reactor fuel demand and U/sub 3/O/sub 8/ production for the years 1983 and 1990. Reactor fuel demand is estimated to increase from 15,900 tons to 21,300 tons U/sub 3/O/sub 8/ respectively. U/sub 3/O/sub 8/ production, however, is estimated to decrease from 10,600 tons to 9600 tons respectively. A field examination was conducted of 29 selected underground uranium mines that represent 84% of the 1982 underground production. Data was gathered regarding population, land ownership and private property valuation. An analysis of the increased cost to production resulting from the installation of 20-meter high exhaust borehole vent stacks was conducted. An assessment was made of the current and future /sup 222/Rn emission levels for a group of 27 uranium mines. It is shown that /sup 222/Rn emission rates are increasing from 10 individual operating mines through 1990 by 1.2 to 3.8 times. But for the group of 27 mines as a whole, a reduction of total /sup 222/Rn emissions is predicted due to 17 of the mines being shutdown and sealed. The estimated total /sup 222/Rn emission rate for this group of mines will be 105 Ci/yr by year end 1983 or 70% of the 1978-79 measured rate and 124 Ci/yr by year end 1990 or 83% of the 1978-79 measured rate.

A waterjet mining machine for use in room and pillar mining operations. [Final report  

SciTech Connect (OSTI)

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.

The Land Use Decision Methodology (LUDM) is a planning framework for mined area land use planning. The LUDM was developed to consider the range of institutional and environmental factors that impact reclamation and land use planning for mined lands. The LUDM was developed as a generalized planning framework rather than a complex/rigid methodology. A matrix that supports the detailed site analysis component of the LUDM was also developed. The matrix has utility for illustrating the impacts that a number of mining related conditions/environmental problems can exert on the environmental feasibility and economics of alternative reclamation plans.

LER Data Mining Pilot Study Final Report  

SciTech Connect (OSTI)

LERs consist of a one page standard form with a standard header and free text data, followed by additional continuation pages of free text data. Currently this LER data is analyzed by first inputting the heading and text data manually into a categorical relational database. The data is then evaluated by enumeration of data in various categories and supplemented by review of individual LERs. This is labor intensive and makes it difficult to relate specific descriptive text to enumerated results. State of the art data mining and visualization technology exists that can eliminate the need for manual categorization, maintain the text relationships within each report, produce the same enumerated results currently available, and provide a tool to support potentially useful additional analysis of the informational content of LERs in a more timely and cost effective manner.

Mining scientific data archives through metadata generation  

SciTech Connect (OSTI)

Data analysis and management tools typically have not supported the documenting of data, so scientists must manually maintain all information pertaining to the context and history of their work. This metadata is critical to effective retrieval and use of the masses of archived data, yet little of it exists on-line or in an accessible format. Exploration of archived legacy data typically proceeds as a laborious process, using commands to navigate through file structures on several machines. This file-at-a-time approach needs to be replaced with a model that represents data as collections of interrelated objects. The tools that support this model must focus attention on data while hiding the complexity of the computational environment. This problem was addressed by developing a tool for exploring large amounts of data in UNIX directories via automatic generation of metadata summaries. This paper describes the model for metadata summaries of collections and the Data Miner tool for interactively traversing directories and automatically generating metadata that serves as a quick overview and index to the archived data. The summaries include thumbnail images as well as links to the data, related directories, and other metadata. Users may personalize the metadata by adding a title and abstract to the summary, which is presented as an HTML page viewed with a World Wide Web browser. We have designed summaries for 3 types of collections of data: contents of a single directory; virtual directories that represent relations between scattered files; and groups of related calculation files. By focusing on the scientists` view of the data mining task, we have developed techniques that assist in the ``detective work `` of mining without requiring knowledge of mundane details about formats and commands. Experiences in working with scientists to design these tools are recounted.

INTEGRATED ROBOT-HUMAN CONTROL IN MINING OPERATIONS  

SciTech Connect (OSTI)

This report describes the results of the 2nd year of a research project on the implementation of a novel human-robot control system for hydraulic machinery. Sensor and valve re-calibration experiments were conducted to improve open loop machine control. A Cartesian control example was tested both in simulation and on the machine; the results are discussed in detail. The machine tests included open-loop as well as closed-loop motion control. Both methods worked reasonably well, due to the high-quality electro-hydraulic valves used on the experimental machine. Experiments on 3-D analysis of the bucket trajectory using marker tracking software are also presented with the results obtained. Open-loop control is robustly stable and free of short-term dynamic problems, but it allows for drifting away from the desired motion kinematics of the machine. A novel, closed-loop control adjustment provides a remedy, while retaining much of the advantages of the open-loop control based on kinematics transformation. Additional analysis of previously recorded, three-dimensional working trajectories of the bucket of large mine shovels was completed. The motion patterns, when transformed into a family of curves, serve as the basis for software-controlled machine kinematics transformation in the new human-robot control system.

Water recovery from acid mine drainage by electrodialysis  

Science Journals Connector (OSTI)

In this study, the possibility of using electrodialysis for the treatment of acid mine drainage generated from coal mining to recover water is investigated. Electrodialysis allows for the separation of anions and metallic cations, possessing the advantages of removing contaminant metals and simultaneously recovering water. To investigate this technology, the passage of anions and cations from three different acid mine drainages through a HDX 200 anion-exchange membrane and a HDX 100 cation-exchange membrane, respectively, was evaluated. The results show that electrodialysis is suitable for recovering water from acid mine drainage, with contaminant removal efficiencies that are greater than 97%. However, the precipitation of iron at the surface of the cation-exchange membrane constitutes a problem for the system by causing a blockage of the membrane through the scaling phenomenon, which reduces the process efficiency.

Salinity gradient solar pond technology applied to potash solution mining  

SciTech Connect (OSTI)

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.

The robot moves in ahead of rescuers to evaluate precarious environments and help them plan the rescue mission. One of the biggest obstacles to rescuing miners after an accident is the unknown level of danger. Before rescuers are able to get miners to safety, they must assess the situation, often taking up time critical to the success of the rescue. Poisonous gases, flooded tunnels, explosive vapors and unstable walls and roofs are among the potentially deadly conditions and unknown obstacles that can slow rescue efforts.

Case studies: developing land uses in surface-mine reclamation  

SciTech Connect (OSTI)

Regulations adopted in 1978 by the Office of Surface Mining (OSM) to implement the Surface Mining Control and Reclamation Act of 1977 foreclosed many opportunities for development of postmining uses because of the requirement to return land to its approximate original contour (AOC), and the difficulty of qualifying for a variance. The regulations all but eliminated development of postmining uses with economic or community benefits. The effect of those regulations was to develop forestland, farmland, and rangeland similar to that which existed before mining. Recent changes in OSM's regulations have made development of postmining uses more feasible by removing many restrictive conditions and interpretations. This report documents the main types of uses that have been developed as postmining uses - recreation, forestry, housing, community facilities, industry, and commercial and mixed urban uses. Most of the cases presented predate the Act, and thus were not developed in a regulatory situation comparable to the present time. However, they demonstrate the practical feasibility and the benefits to local communities of developing postmining uses. The review of examples and case studies leads to three main conclusions: in certain situations surface-mined land may be an important resource for communities; most successful postmining developments required considerable vision and dedicated effort over many years; and an intended postmining use should be studied and planned during the preparation of mining permits so that the mining operation can be coordinated with the postmining use.

GIS-based pre-mining land damage assessment for underground coal mines in high groundwater area  

Science Journals Connector (OSTI)

Coal mining cause different degrees of damage to both land and ecosystems. Evaluation of disturbed land is a fundamental and prerequisite work for land reclamation and rehabilitation. However, most of those evaluations were carried out when mining was under process or after it cease. This paper proposes an innovative assessment model for pre-evaluation which could be implemented before mining activity begins. A geographic information system (GIS) was constructed to evaluate land damage. Three natural condition factors and three geological condition factors were chosen for evaluation. The results show that: land damage was categorised as five degrees, which are negligible, slight, moderate, severe, and very severe. Furthermore, very severely damaged areas are mainly concentrated in the northwest part of the coal mine, whereas slight damaged areas are mainly concentrated in the southwest. The developed coupling technique was used to forecast land damage, and provide reference for reclamation work.

Data transformation techniques for preserving privacy in distance-based mining algorithms  

Science Journals Connector (OSTI)

Dissimilarity calculation between two objects is one of the important knowledge gathering methods in cognition science. Many data mining algorithms explore dissimilarity computation to cluster the data in order to know intra-relations, inter-relations, and outliers in the data. Majority of these algorithms use Euclidean distance as the dissimilarity criterion. In this paper, signal transformation functions, with their orthogonal property and energy compaction features are explored in transforming the data. The data transformation scheme considers entire data as a single entity. The proposed scheme is designed such that it can be used even for the non-Euclidean space by using the distance mapping algorithm. The existing randomisation approaches for data transformation maintain only the distributions and do not maintain the Euclidean distance between the records. The proposed methods are superior to the existing methods in terms of run time complexity O(n) and preservation of distance between individual data points.

Disposal of Fluidized Bed Combustion Ash in an Underground Mine to Control Acid Mine Drainage and Subsidence  

SciTech Connect (OSTI)

This project will evaluate the technical, economic and environmental feasibility of filling abandoned underground mine voids with alkaline, advanced coal combustion wastes (Fluidized Bed Combustion (FBC) ash). Success will be measured in terms of technical feasibility of the approach (i.e. YO void filling), cost, environmental benefits (acid mine drainage and subsidence control) and environmental impacts (noxious ion release). During Phase Ill the majority of the activity involves completing two full scale demonstration projects. The eleven acre Longridge mine in Preston County will be filled with 53,000 cubic yards of grout during the spring of 1998 and monitored for following year. The second demonstration involves stowing 2000 tons of ash into an abandoned mine to demonstrate the newly redesigned Burnett Ejector. This demonstration is anticipated to take place during the winter of 1997. This document will report on progress made during Phase Ill. The report will be divided into four major sections. The first will be the Hydraulic Injection component. This section of the report will report on progress and milestones associated with the grouting activities of the project. The Phase Ill tasks of Economic Analysis and Regulatory Analysis will be covered under this section. The second component is Pneumatic Injection. This section reports on progress made towards completing the demonstration project. The Water Quality component involves background monitoring of water quality and precipitation at the Phase Ill (Longridge) mine site. The last component involves evaluating the migration of contaminants through the grouted mine. A computer model has been developed in earlier phases and will model the flow of water in and around the grouted Longridge mine.

A field test of electromagnetic geophysical techniques for locating simulated in situ mining leach solution  

SciTech Connect (OSTI)

The US Bureau of Mines, The University of Arizona, Sandia National Laboratories, and Zonge Engineering and Research Organization, Inc., conducted cooperative field tests of six electromagnetic (EM) geophysical methods to compare their effectiveness in locating a brine solution simulating in situ leach solution or a high-conductivity plume of contamination. The brine was approximately 160 m below the surface. The testsite was the University's San Xavier experimental mine near Tucson, AZ. Geophysical surveys using surface and surface-borehole, time-domain electromagnetic (TEM) induction; surface controlled-source audiofrequency magnetotellurics (CSAMT); surface-borehole, frequency-domain electromagnetic (FEM) induction; crosshole FEM; and surface magnetic field ellipticity were conducted before and during brine injection. The surface TEM data showed a broad decrease in resistivity. CSAMT measurements with the conventional orientation did not detect the brine, but measurements with another orientation indicated some decrease in resistivity. The surface-borehole and crosshole methods located a known fracture and other fracture zones inferred from borehole induction logs. Surface magnetic field ellipticity data showed a broad decrease in resistivity at depth following brine injection.

Restoring Sustainable Forests on Appalachian Mined Lands for Wood Products, Renewable Energy, Carbon Sequestration, and Other Ecosystem Services  

SciTech Connect (OSTI)

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. We are currently estimating the acreage of lands in Virginia, West Virginia, Kentucky, Ohio, and Pennsylvania mined under SMCRA and reclaimed to non-forested post-mining land uses that are not currently under active management, and therefore can be considered as available for carbon sequestration. To determine actual sequestration under different forest management scenarios, a field study was installed as a 3 x 3 factorial in a random complete block design with three replications at each of three locations, one each in Ohio, West Virginia, and Virginia. The treatments included 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 is 4.5 acres, and the complete installation at each site is 13.5 acres. During the reporting period we determined that by grinding the soil samples to a finer particle size of less than 250 ?m (sieve No. 60), the effect of mine soil coal particle size on the extent to which these particles will be oxidized during the thermal treatment of the carbon partitioning procedure will be eliminated, thus making the procedure more accurate and precise. In the second phase of the carbon sequestration project, we focused our attention on determining the sample size required for carbon accounting on grassland mined fields in order to achieve a desired accuracy and precision of the final soil organic carbon (SOC) estimate. A mine land site quality classification scheme was developed and some field-testing of the methods of implementation was completed. The classification model has been validated for softwoods (white pine) on several reclaimed mine sites in the southern Appalachian coal region. The classification model is a viable method for classifying post-SMCRA abandoned mined lands into productivity classes for white pine. A thinning study was established as a random complete block design to evaluate the response to thinning of a 26-year-old white pine stand growing on a reclaimed surface mine in southwest Virginia. Stand parameters were projected to age 30 using a stand table projection. Site index of the stand was found to be 32.3 m at base age 50 years. Thinning rapidly increased the diameter growth of the residual trees to 0.84 cm yr{sup -1} compared to 0.58 cm yr{sup -1} for the unthinned treatment; however, at age 26, there was no difference in volume or value per hectare. At age 30, the unthinned treatment had a volume of 457.1 m{sup 3} ha{sup -1} but was only worth $8807 ha{sup -1}, while the thinned treatment was projected to have 465.8 m{sup 3} ha{sup -1}, which was worth $11265 ha{sup -1} due to a larger percentage of the volume being in sawtimber size classes.

Evaluation of ground movement and damage to structures from Chinese coal mining using a new GIS coupling model  

Science Journals Connector (OSTI)

In this paper, combining a theoretical method of predicting subsidence over time and using a geographical information system (GIS), a GIS-based dynamic model is proposed to rapid simulate the phenomenon of progressive movement distribution from large sequential mining. The theoretical method uses stochastic medium concept involving Knothe time function for basic governing equations to calculate progressive movement because this solutions have been widely developed and used in Chinese mining practice to solve the coal extraction problem under building, railways, and rivers. In order to assess the impact of progressive movement to the surface structures, a fuzzy model is suggested to identify damage classifications with contributions of subsidence calculations and building mesh data. For implementation of the GIS-based prediction and assessment model, a new GIS coupling model is established by implementing tight coupling strategy using the component object model (COM) program to overcome the problems of complex model integration for dynamic prediction and assessment. Furthermore, this paper demonstrates the effectiveness of this GIS-based model for prediction and evaluation of subsidence-induced damage from coal mining beneath surface structures in China.
