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

SciTech Connect

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.

The New Generation of Uranium In Situ Recovery Facilities: Design Improvements Should Reduce Radiological Impacts Relative to First Generation Uranium Solution Mining Plants  

SciTech Connect

In the last few years, there has been a significant increase in the demand for Uranium as historical inventories have been consumed and new reactor orders are being placed. Numerous mineralized properties around the world are being evaluated for Uranium recovery and new mining / milling projects are being evaluated and developed. Ore bodies which are considered uneconomical to mine by conventional methods such as tunneling or open pits, can be candidates for non-conventional recovery techniques, involving considerably less capital expenditure. Technologies such as Uranium In Situ Leaching / In Situ Recovery (ISL / ISR - also referred to as 'solution mining'), have enabled commercial scale mining and milling of relatively small ore pockets of lower grade, and are expected to make a significant contribution to overall world wide uranium supplies over the next ten years. Commercial size solution mining production facilities have operated in the US since the mid 1970's. However, current designs are expected to result in less radiological wastes and emissions relative to these 'first' generation plants (which were designed, constructed and operated through the 1980's). These early designs typically used alkaline leach chemistries in situ including use of ammonium carbonate which resulted in groundwater restoration challenges, open to air recovery vessels and high temperature calcining systems for final product drying vs the 'zero emissions' vacuum dryers as typically used today. Improved containment, automation and instrumentation control and use of vacuum dryers in the design of current generation plants are expected to reduce production of secondary waste byproduct material, reduce Radon emissions and reduce potential for employee exposure to uranium concentrate aerosols at the back end of the milling process. In Situ Recovery in the U.S. typically involves the circulation of groundwater, fortified with oxidizing (gaseous oxygen e.g) and complexing agents (carbon dioxide, e.g) into an ore body, solubilizing the uranium in situ, and then pumping the solutions to the surface where they are fed to a processing plant ( mill). Processing involves ion exchange and may also include precipitation, drying or calcining and packaging operations depending on facility specifics. This paper presents an overview of the ISR process and the health physics monitoring programs developed at a number of commercial scale ISL / ISR Uranium recovery and production facilities as a result of the radiological character of these processes. Although many radiological aspects of the process are similar to that of conventional mills, conventional-type tailings as such are not generated. However, liquid and solid byproduct materials may be generated and impounded. The quantity and radiological character of these by products are related to facility specifics. Some special monitoring considerations are presented which are required due to the manner in which radon gas is evolved in the process and the unique aspects of controlling solution flow patterns underground. The radiological character of these processes are described using empirical data collected from many operating facilities. Additionally, the major aspects of the health physics and radiation protection programs that were developed at these first generation facilities are discussed and contrasted to circumstances of the current generation and state of the art of uranium ISR technologies and facilities. In summary: This paper has presented an overview of in situ Uranium recovery processes and associated major radiological aspects and monitoring considerations. Admittedly, the purpose was to present an overview of those special health physics considerations dictated by the in situ Uranium recovery technology, to point out similarities and differences to conventional mill programs and to contrast these alkaline leach facilities to modern day ISR designs. As evidenced by the large number of ISR projects currently under development in the U.S. and worldwide, non conventional Uranium recovery techniques

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

SciTech Connect

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.

Uranium industry annual 1993  

SciTech Connect

Uranium production in the United States has declined dramatically from a peak of 43.7 million pounds U{sub 3}O{sub 8} (16.8 thousand metric tons uranium (U)) in 1980 to 3.1 million pounds U{sub 3}O{sub 8} (1.2 thousand metric tons U) in 1993. This decline is attributed to the world uranium market experiencing oversupply and intense competition. Large inventories of uranium accumulated when optimistic forecasts for growth in nuclear power generation were not realized. The other factor which is affecting U.S. uranium production is that some other countries, notably Australia and Canada, possess higher quality uranium reserves that can be mined at lower costs than those of the United States. Realizing its competitive advantage, Canada was the world`s largest producer in 1993 with an output of 23.9 million pounds U{sub 3}O{sub 8} (9.2 thousand metric tons U). The U.S. uranium industry, responding to over a decade of declining market prices, has downsized and adopted less costly and more efficient production methods. The main result has been a suspension of production from conventional mines and mills. Since mid-1992, only nonconventional production facilities, chiefly in situ leach (ISL) mining and byproduct recovery, have operated in the United States. In contrast, nonconventional sources provided only 13 percent of the uranium produced in 1980. ISL mining has developed into the most cost efficient and environmentally acceptable method for producing uranium in the United States. The process, also known as solution mining, differs from conventional mining in that solutions are used to recover uranium from the ground without excavating the ore and generating associated solid waste. This article describes the current ISL Yang technology and its regulatory approval process, and provides an analysis of the factors favoring ISL mining over conventional methods in a declining uranium market.

An Enhancer Near ISL1 and an Ultraconserved Exon of PCBP2 areDerived from a Retroposon  

SciTech Connect

Hundreds of highly conserved distal cis-regulatory elementshave been characterized to date in vertebrate genomes1. Many thousandsmore are predicted based on comparative genomics2,3. Yet, in starkcontrast to the genes they regulate, virtually none of these regions canbe traced using sequence similarity in invertebrates, leaving theirevolutionary origin obscure. Here we show that a class of conserved,primarily non-coding regions in tetrapods originated from a novel shortinterspersed repetitive element (SINE) retroposon family that was activein Sarcopterygii (lobe-finned fishes and terrestrial vertebrates) in theSilurian at least 410 Mya4, and, remarkably, appears to be recentlyactive in the "living fossil" Indonesian coelacanth, Latimeriamenadoensis. We show that one copy is a distal enhancer, located 500kbfrom the neuro-developmental gene ISL1. Several others represent new,possibly regulatory, alternatively spliced exons in the middle ofpre-existing Sarcopterygian genes. One of these is the>200bpultraconserved region5, 100 percent identical in mammals, and 80 percentidentical to the coelacanth SINE, that contains a 31aa alternativelyspliced exon of the mRNA processing gene PCBP26. These add to a growinglist of examples7 in which relics of transposable elements have acquireda function that serves their host, a process termed "exaptation"8, andprovide an origin for at least some of the highly-conservedvertebrate-specific genomic sequences recently discovered usingcomparative genomics.

Uranium Mining and Enrichment  

NLE Websites -- All DOE Office Websites (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%.

Mining the earth  

SciTech Connect

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.

Radiological aspects of in situ uranium recovery  

SciTech Connect

In the last few years, there has been a significant increase in the demand for Uranium as historical inventories have been consumed and new reactor orders are being placed. Numerous mineralized properties around the world are being evaluated for Uranium recovery and new mining / milling projects are being evaluated and developed. Ore bodies which are considered uneconomical to mine by conventional methods such as tunneling or open pits, can be candidates for non-conventional recovery techniques, involving considerably less capital expenditure. Technologies such as Uranium in situ leaching in situ recovery (ISL / ISR), have enabled commercial scale mining and milling of relatively small ore pockets of lower grade, and may make a significant contribution to overall world wide uranium supplies over the next ten years. Commercial size solution mining production facilities have operated in the US since 1975. Solution mining involves the pumping of groundwater, fortified with oxidizing and complexing agents into an ore body, solubilizing the uranium in situ, and then pumping the solutions to the surface where they are fed to a processing plant. Processing involves ion exchange and may also include precipitation, drying or calcining and packaging operations depending on facility specifics. This paper presents an overview of the ISR process and the health physics monitoring programs developed at a number of commercial scale ISL / ISR Uranium recovery and production facilities as a result of the radiological character of these processes. Although many radiological aspects of the process are similar to that of conventional mills, conventional-type tailings as such are not generated. However, liquid and solid byproduct materials may be generated and impounded. The quantity and radiological character of these by products are related to facility specifics. Some special monitoring considerations are presented which are required due to the manner in which Radon gas is evolved in the process and the unique aspects of controlling solution flow patterns underground. An overview of the major aspects of the health physics and radiation protection programs that were developed at these facilities are discussed and contrasted to circumstances of the current generation and state of the art of Uranium ISR technologies and facilities.

Saving energy in mining  

SciTech Connect

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.

Surface mine reclamation for wildlife  

SciTech Connect

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.

Logistics background study: underground mining  

SciTech Connect

Logistical functions that are normally associated with US underground coal mining are investigated and analyzed. These functions imply all activities and services that support the producing sections of the mine. 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.

UK mining invests, suppliers profit  

SciTech Connect

In the midst of a major economic crisis in the United Kingdom, equipment suppliers have been reporting a number of considerable purchases by British coal mining companies. In December 2008, Liebherr-Great Britain delivered the first two of four Rq350 Litronic hydraulic excavators for use at the Broken Cross opencast coal site in Lanarkshire, Scotland. Ten Terex TR100 rigid haulers were delivered to the site in late 2008. Hatfield Colliery at Stainforth, South Yorkshire, has been reopened by PowerFuel. The main equipment for two longwall faces was supplied by Joy Mining Machinery UK Ltd. 2 photos.

The kinds of minerals extracted from the earth vary widely. For thousands of years, these and other minerals have provided the raw materials with which human civilizations have been built. The United States Department of Energy and the National Mining Association are working in partnership to implement the Mining Industry of the Future strategy. Cooperatively, the Department of Energy and National Mining Association selected specific mineral commodities to review in this Mining Energy and Environmental Profile.

Semi autonomous mine detection system  

SciTech Connect

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.

Longwall mining of thin seams  

SciTech Connect

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.

Mined land reclamation by biological reactivation  

SciTech Connect

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.

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

SciTech Connect

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.

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

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.

Acoustic resonance for nonmetallic mine detection  

SciTech Connect

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.

Regulating for the long term: SMCRA and acid mine drainage  

SciTech Connect

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.

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.

Surface mining environmental monitoring and reclamation handbook  

SciTech Connect

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

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.

Influence of lithology on longwall mining subsidence  

SciTech Connect

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.

Reduction of fire hazards on large mining equipment  

SciTech Connect

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

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

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

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.

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.

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

SciTech Connect

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  

NLE Websites -- All DOE Office Websites (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

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

SciTech Connect

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.

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

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.

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.

We present a belief-driven method for extracting unexpected web usage sequences, where the belief system consists of a temporal relation and semantics constrained sequence rules acquired with respect to prior knowledge. Our experiments show the effectiveness and usefulness of the proposed approach. Furthermore, discovered rules of unexpected web usage can be used for web content personalisation and recommendation, site structure optimisation and critical event prediction.

Case study of groundwater impact caused by underground mining  

SciTech Connect

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.

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

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.

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

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. Todays 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.

US uranium mining industry: background information on economics and emissions  

SciTech Connect

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

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.

Assessing the land use suitability of mined areas in Appalachia  

SciTech Connect

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.

Directional drilling techniques for exploration in-advance of mining  

SciTech Connect

In-seam directionally drilled horizontal boreholes have provided effective solutions in underground coal mines for methane and water drainage and inherently provide an excellent tool for coalbed exploration. Directionally drilled methane drainage boreholes have identified rapid changes in coalbed elevation, coalbed thickness and faults. Specific directional drilling and coring procedures for exploration in-advance of mining are reviewed in this paper, and also other directional drilling applications including in-mine horizontal gob ventilation boreholes, identification of abandoned workings, and water drainage boreholes.

LER Data Mining Pilot Study Final Report  

SciTech Connect

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

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.

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

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.

Application of GIS on forecasting water disaster in coal mines  

SciTech Connect

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.

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

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.

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...

The Kelastic variable wall mining machine. Interim final report  

SciTech Connect

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.

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

SciTech Connect

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.

Technology experience and economics of oil shale mining in Estonia  

SciTech Connect

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.

Coal mining and the resource community cycle: A longitudinal assessment of the social impacts of the Coppabella coal mine  

SciTech Connect

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

Potential highwall use by raptors in coal mine reclamation  

SciTech Connect

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.

Geologic factors in coal mines roof stability: a progress report  

SciTech Connect

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.

Extrasolar Asteroid Mining as Forensic Evidence for Extraterrestrial Intelligence  

E-Print Network (OSTI)

The development of civilisations like ours into spacefaring, multi-planet entities requires significant raw materials to construct vehicles and habitats. Interplanetary debris, including asteroids and comets, may provide such a source of raw materials. In this article we present the hypothesis that extraterrestrial intelligences (ETIs) engaged in asteroid mining may be detectable from Earth. Considering the detected disc of debris around Vega as a template, we explore the observational signatures of targeted asteroid mining (TAM), such as unexplained deficits in chemical species, changes in the size distribution of debris and other thermal signatures which may be detectable in the spectral energy distribution (SED) of a debris disc. We find that individual observational signatures of asteroid mining can be explained by natural phenomena, and as such they cannot provide conclusive detections of ETIs. But, it may be the case that several signatures appearing in the same system will prove harder to model without...

The characteristics and conditions of coal measures rock were considered prior to the preparation of the models and the insertion of support. The investigation has clearly shown how floor lift, roof failure and sidewall movements of mine roadways in laminated weak rock conditions gradually develops as a result of the increase in the stress and, also, how it is related to the level of support used.

Evaluation of airborne geophysical surveys for large-scale mapping of contaminated mine pools: draft final report  

SciTech Connect

Decades of underground coal mining has left about 5,000 square miles of abandoned mine workings that are rapidly filling with water. The water quality of mine pools is often poor; environmental regulatory agencies are concerned because water from mine pools could contaminate diminishing surface and groundwater supplies. Mine pools are also a threat to the safety of current mining operations. Conversely, mine pools are a large, untapped water resource that, with treatment, could be used for a variety of industrial purposes. Others have proposed using mine pools in conjunction with heat pumps as a source of heating and cooling for large industrial facilities. The management or use of mine pool water requires accurate maps of mine pools. West Virginia University has predicted the likely location and volume of mine pools in the Pittsburgh Coalbed using existing mine maps, structure contour maps, and measured mine pool elevations. Unfortunately, mine maps only reflect conditions at the time of mining, are not available for all mines, and do not always denote the maximum extent of mining. Since 1999, the National Energy Technology Laboratory (NETL) has been evaluating helicopter-borne, electromagnetic sensing technologies for the detection and mapping of mine pools. Frequency domain electromagnetic sensors are able to detect shallow mine pools (depth < 50 m) if there is sufficient contrast between the conductance of the mine pool and the conductance of the overburden. The mine pools (conductors) most confidently detected by this technology are overlain by thick, resistive sandstone layers. In 2003, a helicopter time domain electromagnetic sensor was applied to mined areas in southwestern Virginia in an attempt to increase the depth of mine pool detection. This study failed because the mine pool targets were thin and not very conductive. Also, large areas of the surveys were degraded or made unusable by excessive amounts of cultural electromagnetic noise that obscured the subtle mine pool anomalies. However, post-survey modeling suggested that thicker, more conductive mine pools might be detected at a more suitable location. The current study sought to identify the best time domain electromagnetic sensor for detecting mine pools and to test it in an area where the mine pools are thicker and more conductive that those in southwestern Virginia. After a careful comparison of all airborne time domain electromagnetic sensors (including both helicopter and fixed-wing systems), the SkyTEM system from Denmark was determined to be the best technology for this application. Whereas most airborne time domain electromagnetic systems were developed to find large, deep, highly conductive mineral deposits, the SkyTEM system is designed for groundwater exploration studies, an application similar to mine pool detection.

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

SciTech Connect

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.

Mortality in Appalachian coal mining regions: the value of statistical life lost  

SciTech Connect

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

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

SciTech Connect

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.

INTEGRATED ROBOT-HUMAN CONTROL IN MINING OPERATIONS  

SciTech Connect

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.

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

SciTech Connect

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. % void filling), cost, environmental benefits (acid mine drainage and subsidence control) and environmental impacts (noxious ion release). This document reports on progress made during Phase III. The report is divided into three major sections. The first deals with the Hydraulic Injection component. This section of the report describes the progress and milestones associated with the grouting activities of the project. The Phase III tasks of Economic Analysis and Regulatory Analysis is covered under this section. The second component is Pneumatic Injection. This section reports on progress made towards completing the demonstration project. 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.

The association between mountaintop mining and birth defects among live births in central Appalachia, 19962003  

Science Journals Connector (OSTI)

Birth defects are examined in mountaintop coal mining areas compared to other coal mining areas and non-mining areas of central Appalachia. The study hypothesis is that higher birth-defect rates are present in mountaintop mining areas. National Center for Health Statistics natality files were used to analyze 19962003 live births in four Central Appalachian states (N=1,889,071). Poisson regression models that control for covariates compare birth defect prevalence rates associated with maternal residence in county mining type: mountaintop mining areas, other mining areas, or non-mining areas. The prevalence rate ratio (PRR) for any birth defect was significantly higher in mountaintop mining areas compared to non-mining areas (PRR=1.26, 95% CI=1.21, 1.32), after controlling for covariates. Rates were significantly higher in mountaintop mining areas for six of seven types of defects: circulatory/respiratory, central nervous system, musculoskeletal, gastrointestinal, urogenital, and other. There was evidence that mountaintop mining effects became more pronounced in the latter years (20002003) versus earlier years (19961999.) Spatial correlation between mountaintop mining and birth defects was also present, suggesting effects of mountaintop mining in a focal county on birth defects in neighboring counties. Elevated birth defect rates are partly a function of socioeconomic disadvantage, but remain elevated after controlling for those risks. Both socioeconomic and environmental influences in mountaintop mining areas may be contributing factors.

Remote controlled underground mining system preliminary design and concept plans. Final report  

SciTech Connect

The proposed mining technique has the potential to mine coal from underground horizontal or pitching seams in the 9-foot thickness range at an estimated cost ranging from $7.987 to $10.152 per ton. The estimate is established on conclusions drawn from: (1) the anticipated mining rate, in terms of tons per hour, that the mining system's hardware is expected to achieve as an average; (2) the approximate cost of the mining hardware amortized on a production service life expectancy of 4,000,000 tons; (3) logistics pertinent to continuous mine production, requiring the operation of two Mining Rigs simultaneously with operating crews totaling to 9 men per shift; (4) the angle of the mine bores into pitching seams extend, whenever possible, to no more than 30/sup 0/ from the horizontal; (5) mine bores extend to maximum feasible or permissible length. A bore length of 2500 feet is considered feasible; and (6) gas recovery from the mine bores can be accomplished with relative ease. The value of this, however, has not been determined since its handling as a recoverable requires investigation on hardware assemblies necessary to its processing, and the volume that must exist to invite a commercially attractive effort.

Computer methods for surface mine evaluation in the Appalachian coalfield  

SciTech Connect

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.

Thin seam mines in Appalachia yield high production  

SciTech Connect

One-unit coal mines operating in certain flat, dry, and non-gassey seams often have continuous haulage from the face to the surface. Though some seams are so thin that miners must crawl on hands and knees, production is excellent. In thin coal seams that many an experienced miner might feel are unminable, operators in Harlan County, Kentucky, United States, are cutting coal with marked success. One-unit operations in seams no thicker than 625 millimeters (25 inches) are producing up to 7,000 tons of coal per month while operating only one shift per day, five days per week. Good mining conditions and continuous haulage of coal from the face to the surface are two reasons why.
