  1. Production of Ultrafine, High-purity Ceramic Powders Using the US Bureau of Mines Developed Turbomill

    Science.gov (United States)

    Hoyer, Jesse L.

    1993-01-01

    Turbomilling, an innovative grinding technology developed by the U.S. Bureau of Mines in the early 1960's for delaminating filler-grade kaolinitic clays, has been expanded into the areas of particle size reduction, material mixing, and process reaction kinetics. The turbomill, originally called an attrition grinder, has been used for particle size reduction of many minerals, including natural and synthetic mica, pyrophyllite, talc, and marble. In recent years, an all-polymer version of the turbomill has been used to produce ultrafine, high-purity, advanced ceramic powders such as SiC, Si3N4, TiB2, and ZrO2. In addition to particle size reduction, the turbomill has been used to produce intimate mixtures of high surface area powders and whiskers. Raw materials, TiN, AlN, and Al2O3, used to produce a titanium nitride/aluminum oxynitride (TiN/AlON) composite, were mixed in the turbomill, resulting in strength increases over samples prepared by dry ball milling. Using the turbomill as a leach vessel, it was found that 90.4 pct of the copper was extracted from the chalcopyrite during a 4-hour leach test in ferric sulfate versus conventional processing which involves either roasting of the ore for Cu recovery or leaching of the ore for several days.

  2. Negative hysteresis effect observed during calibration of the US Bureau of Mines borehole deformation gauge

    International Nuclear Information System (INIS)

    The US Bureau of Mines borehole deformation gauge (BMG) was designed in the early 1960's to allow rock stress measurements by the overcoring method. Since that time it has become a de facto standard against which the performance of other borehole deformation gauges is often judged. However, during recent in situ stress studies in the Climax Stock at the Nevada Test Site a strange ''negative hysteresis'' in the order of 300 to 500 microstrains was observed in standard calibration data. Here, the relaxation curve lies below the indentation (compression) curves as if the system were to somehow respond with an energy release. Therefore, a precision micro-indentation apparatus has been designed and used to perform a series of tests allowing a better understanding of the BMG button to cantilever interaction. Results indicate that the hysteresis effect is caused by differential motion between the button base and the cantilever resulting from the geometric motion inherent in the cantilever. The very large apparent hysteresis is mainly caused by cycling opposing cantilevers through the instrument's entire dynamic range, and the fundamental imprecision inherent in use of the standard micrometers to calibrate the BMG. Laboratory mean hysteresis magnitudes for a polished cantilever typically range from 3 to 25 microstrain for 100 and 1000 microstrain relaxations on 1000 microstrain deflection loops intended to simulate typical field data. The error percentage is thought to remain fairly constant with deformation loop size, and is sufficiently small such that it can be safely ignored. The hysteresis effect can probably be reduced, and instrument stability improved by machining a small 90 degree cone in the cantilever in which a slightly larger mating cone on the base of the indentation button would reside. 5 refs. 26 figs., 1 tab

  3. U.S. Bureau of Mines, Phase 1 Hanford low-level waste melter tests. Final report

    International Nuclear Information System (INIS)

    A multiphase program was initiated in 1994 to test commercially available melter technologies for the vitrification of the low-level waste (LLW) stream from defense wastes stored in underground tanks at the Hanford Site in southeastern Washington State. Phase 1 of the melter demonstration tests using simulated LLW was completed during fiscal year 1995. This document is the melter offgas report on testing performed by the U.S. Department of the Interior, Bureau of Mines, Albany Research Center in Albany, Oregon. The Bureau of Mines (one of the seven vendors selected) was chosen to demonstrate carbon electrode melter technology (also called carbon arc or electric arc) under WHC Subcontract number MMI-SVV-384216. The report contains description of the tests, observation, test data and some analysis of the data as it pertains to application of this technology for LLW vitrification. Testing consisted of melter feed preparation and three melter tests, the first of which was to fulfill the requirements of the statement of work (WHC-SD-EM-RD-044), and the second and third were to address issues identified during the first test. The document also contains summaries of the melter offgas report issued as a separate document U.S. Bureau of Mines, Phase 1 Hanford Low-Level Waste Melter Tests: Melter Offgas Report (WHC-SD-WM-VI-032)

  4. U.S. Bureau of Mines, phase I Hanford low-level waste melter tests: Melter offgas report

    International Nuclear Information System (INIS)

    A multiphase program was initiated in 1994 to test commercially available melter technologies for the vitrification of the low-level waste (LLW) stream from defense wastes stored in underground tanks at the Hanford Site in southeastern Washington State. Phase 1 of the melter demonstration tests using simulated LLW was completed during fiscal year 1995. This document is the melter offgas report on testing performed by the U.S. Department of the Interior, Bureau of Mines, Albany Research Center in Albany, Oregon. The Bureau of Mines (one of the seven vendors selected) was chosen to demonstrate carbon electrode melter technology (also called carbon arc or electric arc) under WHC subcontract number MMI-SVV-384216. The document contains the complete offgas report for the first 24-hour melter test (WHC-1) as prepared by Entropy Inc. A summary of this report is also contained in the''U.S. Bureau of Mines, Phase 1 Hanford Low-Level Waste Melter Tests: Final Report'' (WHC-SD-WM-VI-030)

  5. GASFLOW comparisons with bureau of mines experiments

    International Nuclear Information System (INIS)

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

  6. US Bureau of Mines pilot-scale demonstration of electric arc furnace melting of multiple-source simulated low-level radioactive wastes

    International Nuclear Information System (INIS)

    The U.S. Bureau of Mines, in cooperation with Department of Energy (DOE) contractors Westinghouse Hanford Company (WHC) and Lockheed Idaho Technology Company (LITCO), conducted two extended melting campaigns in the electric arc furnace on radically different feeds. The WHC feed contained a high sodium, low-level radioactive liquid waste (LLW) simulant, and industrial glass-forming minerals designed to produce a final glass with 5 pct B2O3 and 20 pct Na2O. Preparation of dry furnace feed required absorbing the LLW simulant into the glass forniers and performing a low-temperature denitrification reaction. Nearly 22,000 lb of dry, denitrified feed, at feed rates from 250 to 750 lb/h, and average power of 400 kW, was melted producing over 18,000 lb of glass. The LITCO feeds were designed to simulate as-retrieved buried mixed wastes stored at the Idaho National Engineering Laboratory (INEL) Radioactive Waste Management Complex (RWMC). These feeds consisted of non-contaminated soil excavated from the RWMC, industrial mineral absorbents, scrap metals, oils, grease, and other combustible constituents, and lime added to the mix to produce a slag with molar basicity of 1.0. Over 18,000 lb of feed, with up to 25 pct combustible content, at feed rates up to 1,200 lb/h and average power of 230 kW, was melted producing over 10,000 lb of slag and 1,800 lb of metal. Material balances and facility operating conditions for each run are described. These tests demonstrated the flexibility and versatility of the electric arc furnace for the vitrification of the waste streams

  7. Bureau of Mines method of calibrating a primary radon measuring apparatus

    International Nuclear Information System (INIS)

    This paper reports on the Bureau of Mines method of calibrating a primary radon measuring apparatus. One requirement for accurate monitoring of radon in working environments, dwellings, and outdoors is to ensure that the measurement instrumentation is properly calibrated against a recognized standard. To achieve this goal, the U.S. Bureau of Mines Radiation Laboratory has participated since 1988 in a program to establish international radon measurement standards. Originally sponsored by the Organization for Economic Cooperation and Development (OECD), the program is also sponsored by the International Atomic Energy Agency. While the National Institute of Standards and Technology (NIST) radium solution ampules are acceptable to all participating laboratories as a primary standard, a method of transferring radon from the NIST source into The Bureau's method transfers radon from the primary solution by bubbling 3 L of air through it into a steel cylinder. After homogenizing the radon concentrations in the cylinder, eight alpha-scintillation cells are filled consecutively and measured in a standard counting system. The resulting efficiency is 81.7 ± 1.2 pct

  9. Technology innovation and management in the US Bureau of the Census: Discussion and recommendations

    Energy Technology Data Exchange (ETDEWEB)

    Tonn, B.; Edwards, R.; Goeltz, R.; Hake, K.

    1990-09-01

    This report contains a set of recommendations prepared by Oak Ridge National Laboratory (ORNL) for the US Bureau of the Census pertaining to technology innovation and management. Technology has the potential to benefit the Bureau's data collection, capture, processing, and analysis activities. The entire Bureau was represented from Decennial Census to Economic Programs and various levels of Bureau management and numerous experts in technology. Throughout the Bureau, workstations, minicomputers, and microcomputers have found their place along side the Bureau's mainframes. The Bureau's new computer file structure called the Topologically Integrated Geographic Encoding and Referencing data base (TIGER) represents a major innovation in geographic information systems and impressive progress has been made with Computer Assisted Telephone Interviewing (CATI). Other innovations, such as SPRING, which aims to provide Bureau demographic analysts with the capability of interactive data analysis on minicomputers, are in the initial stages of development. Recommendations fall into five independent, but mutually beneficial categories. (1) The ADP Steering Committee be disbanded and replaced with The Technology Forum. (2) Establishment of a Technology Review Committee (TRC), to be composed of technology experts from outside the Bureau. (3) Designate technological gurus. These individuals will be the Bureau's experts in new and innovative technologies. (4) Adopt a technology innovation process. (5) Establish an Advanced Technology Studies Staff (ATSS) to promote technology transfer, obtain funding for technological innovation, manage innovation projects unable to find a home in other divisions, evaluate innovations that cut across Bureau organizational boundaries, and provide input into Bureau technology analyses.

  11. Thermal conductivity of the rocks in the Bureau of Mines Standard Rock Suite

    International Nuclear Information System (INIS)

    Thermal conductivities of eight rocks from the Bureau of Mines Standard Rock Suite were measured in air over the temperature range 373 to 5330K (100 to 2600C). The thermal conductivities of these rocks were measured to furnish standards for future comparisons with host rock from prospective nuclear waste repository sites. The thermal conductivity at a given temperature decreased by as much as 9% after a specimen had been heated to the maximum temperature (5330K), but additional heating cycles had no further effect. This decrease was smallest in the igneous rocks and largest in the sedimentary types. Variations due to orientation were within the precision of measurements (+- 5%). In most cases the thermal conductivities were linear with the reciprocal of the temperature and were within 14% of published data obtained by other methods. Measurements were made by a cut-bar comparison method in which the sample was sandwiched between two reference or metering bars made of Pyroceram 9606 glass-ceramic. The apparatus consisted of a Dynatech Model TCFCM-N20 comparative thermal conductivity analyzer controlled by a Hewlett Packard Model 3052A data acquisition system. A program was written to increment and cycle the temperature in steps between predetermined initial and maximum values. At each step the thermal conductivity was measured after steady-state conditions were established. The rocks furnished by the Bureau of Mines were quarried in large and fairly homogeneous lots for use by researchers at various laboratories. To investigate any anisotropy, cores were taken from each rock cube perpendicular to each of the cube faces. Samples 2 in. in diameter and approx. 0.75 in. thick were prepared from the cores and were dried in a vacuum oven for at least one month prior to taking measurements

  12. Decapitating the U.S. Census Bureau's "head of household": feminist mobilization in the 1970s.

    Science.gov (United States)

    Presser, H B

    1998-01-01

    "In 1970, as in previous decades, the U.S. Bureau of the Census's household enumeration began with a lead question as to who was the ¿head of household'. With the resurgence of feminism, this concept was challenged as an ambiguous concept which implied an authority structure imputed by the Bureau but not measured, and offensive to many people. This paper tells the story of successful feminist mobilization in the 1970s that led to the removal of this concept from the U.S. decennial censuses beginning with 1980." PMID:12294932

    Estep, Leland

    2007-01-01

    Presently, the BLM (Bureau of Land Management) has identified a multitude of abandoned mine sites in primarily Western states for cleanup. These sites are prioritized and appropriate cleanup has been called in to reclaim the sites. The task is great in needing considerable amounts of agency resources. For instance, in Colorado alone there exists an estimated 23,000 abandoned mines. The problem is not limited to Colorado or to the United States. Cooperation for reclamation is sought at local, state, and federal agency level to aid in identification, inventory, and cleanup efforts. Dangers posed by abandoned mines are recognized widely and will tend to increase with time because some of these areas are increasingly used for recreation and, in some cases, have been or are in the process of development. In some cases, mines are often vandalized once they are closed. The perpetrators leave them open, so others can then access the mines without realizing the danger posed. Abandoned mine workings often fill with water or oxygen-deficient air and dangerous gases following mining. If the workings are accidentally entered into, water or bad air can prove fatal to those underground. Moreover, mine residue drainage negatively impacts the local watershed ecology. Some of the major hazards that might be monitored by higher-resolution satellites include acid mine drainage, clogged streams, impoundments, slides, piles, embankments, hazardous equipment or facilities, surface burning, smoke from underground fires, and mine openings.

  4. USBM [United States Bureau of Mines] borehole deformation gage absolute stress measurement test procedure: Final draft

    International Nuclear Information System (INIS)

    The technique described herein for determining the magnitudes and directions of the in situ principal stresses utilizes the stress relief in a small volume of rock when it is physically isolated from the surrounding rock mass. Measurements of deformation are related to stress magnitudes through an understanding of the constitutive behavior of the rock. The behaviors of the non-salt strata around the ESF are expected to conform approximately to that of uniform homogeneous linear-elastic materials having either isotropic or transverse isotropic properties, for which constitutive relations are developed. The constitutive behavior of the salt strata is not well understood and so the overcoring technique yields information of only very limited use. For this reason the overcoring technique will not be used in the salt strata. The technique has also limited application in rocks containing joints spaced less than 8 in. (0.2 m) apart, unless a large number of test can be performed to obtain, a good statistical average. However, such unfavorably discontinuous rocks are not expected as a norm at the Deaf Smith County site. 7 refs., 22 figs., 4 tabs

  8. U.S. Department of Energy Office of Legacy Management Legacy Uranium Mine Site Reclamation - Lessons Learned - 12384

    International Nuclear Information System (INIS)

    The U.S. Department of Energy (DOE) Office of Legacy Management is responsible for administering the DOE Uranium Leasing Program (ULP) and its 31 uranium lease tracts located in the Uravan Mineral Belt of southwestern Colorado (see Figure 1). In addition to administering the ULP for the last six decades, DOE has also undertaken the significant task of reclaiming a large number of abandoned uranium (legacy) mine sites and associated features located throughout the Uravan Mineral Belt. In 1995, DOE initiated a 3-year reconnaissance program to locate and delineate (through extensive on-the-ground mapping) the legacy mine sites and associated features contained within the historically defined boundaries of its uranium lease tracts. During that same time frame, DOE recognized the lack of regulations pertaining to the reclamation of legacy mine sites and contacted the U.S. Bureau of Land Management (BLM) concerning the reclamation of legacy mine sites. In November 1995, The BLM Colorado State Office formally issued the United States Department of the Interior, Colorado Bureau of Land Management, Closure/Reclamation Guidelines, Abandoned Uranium Mine Sites as a supplement to its Solid Minerals Reclamation Handbook (H-3042-1). Over the next five-and-one-half years, DOE reclaimed the 161 legacy mine sites that had been identified on DOE withdrawn lands. By the late 1990's, the various BLM field offices in southwestern Colorado began to recognize DOE's experience and expertise in reclaiming legacy mine sites. During the ensuing 8 years, BLM funded DOE (through a series of task orders) to perform reclamation activities at 182 BLM mine sites. To date, DOE has reclaimed 372 separate and distinct legacy mine sites. During this process, DOE has learned many lessons and is willing to share those lessons with others in the reclamation industry because there are still many legacy mine sites not yet reclaimed. DOE currently administers 31 lease tracts (11,017 ha) that collectively

  11. Novel concepts for recovery of nuclear grade zirconium oxide from Bureau of Mines zirconyl chloride strip liquors. Final report, October 1979-March 1980

    International Nuclear Information System (INIS)

    Results of research on the hydrothermal precipitation of zirconium oxide from the Bureau of Mines zirconyl chloride-sulfate strip liquors indicate that nuclear-grade material can be prepared by this process. Greater than 99 pct of the zirconium value can be precipitated at 250 to 260 C in short reaction time without consumption of acid value of the liquor. Thus, precipitation of zirconium dioxide on a continuous basis, that is, the zirconium dioxide is precipitated in a continuous mode of operation by pumping the strip liquor through a heated pressurized reactor and recycle of the acidic liquor to the process stage are favored. The results of accompanying studies of liquid-solid separation, product washing and dewatering, product purity, and chlorination of the product are presented and discussed

  13. Improving mine safety technology and training in the U.S. recommendations of the Mine Safety Technology and Training Commission

    Institute of Scientific and Technical Information of China (English)

    GRAYSON R. Larry

    2008-01-01

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

    1978-01-01

    Bureau research programs and projects are designed to address many of the State's major concerns in the areas of geologic, energy, mineral, land, and environmental resouces. Research programs incorporate geologic concepts that will build toward an understanding of a specific resource and its impact on human activities. In addition to resource assessments in uranium, lignite, and geopressured geothermal energy, the Bureau continued research into analysis of governmental policy related to energy. Systemic geologic mapping, coastal studies, basin analysis projects, and investigations in other areas of economic geology further indicate the range of research programs carried forward in 1978. Specifically, research on mineral resources and land resources, coastal studies, hydrogeology, basin studies, geologic mapping, and other research (tektites and meteorites, carboniferous of Texas, depositional environments of the Marble Falls Formation, Central Texas) are reported. The establishment of the Mining and Mineral Resources Research Institute is followed. Contracts and grant support and contract reports are listed. The publications eminating from the Bureau are listed. Services rendered by the Bureau and personnel information are included. (MCW)

    Although production of U3O8 declined only slightly in 1980, New Mexico's share of domestic production has declined from 48% in 1976 to 35% in 1980. Production projections indicate a continued decline in 1981 and lower production until at least 1984. New Mexico has 41% of total domestic reserves producible in the $50-per-lb cost category. In keeping with the anticipated steady depletion of reserves, production of crude oil in New Mexico was 69.9 million bls, a 6.3% decline in production from 1979. Condensate production of 5.4 million bbls in 1980, however, represented an increase of 7% from 1979 production. Although natural gas production was the lowest since 1970 and declined by 2.6% from 1979 production, 1980 was the 15th year that production exceeded 1 trillion cu ft. Despite declines in production, the valuation of oil and gas production has increased significantly with oil sales doubling from the previous year and gas sales increasing by $409 million because of higher prices. Reserves have been estimated to be 959 million bbls of crude oil and 17.667 trillion cu ft of natural gas. Production of 19.5 million short tons of coal in 1980 represented a 33% increase over 1979 production and an increase of 157% since 1970. Coal resources in New Mexico are estimated to be 180.79 billion short tons, and production is projected to incease to 39.61 million tons in 1985 and 67.53 million tons in 1990. The most notable developments in geothermal energy have been in technical advances in drilling, testing, and applications, especially in the area of hot dry rock systems. The US Bureau of Land Management has issued 113 geothermal leases that remain active. Recent geothermal exploration activity has been detailed for 21 companies

  2. Formerly utilized MED/AEC sites remedial action progam. Radiological survey of the Albany Metallurgical Research Center, United States Bureau of Mines, Biomass Facility and the Back Forty Area, Albany, Oregon

    International Nuclear Information System (INIS)

    This report contains survey results identifying the current radiological condition of two areas located at the site of the United States Bureau of Mines' Albany Metallurgical Research Center in Albany, Oregon. These areas are designed as the BioMass Facility and the Back Forty. The BioMass Facility was a pilot plant for the production of oil from wood waste; it consists of five structures on a two-acre site. The Back Forty is a vacant area of about 14 acres south of the BioMass Facility. Both areas were reportedly used as dump sites for the Bureau of Mines operations. No contamination was found to be associated with the structures, equipment, or material in the BioMass Facility; however, four relatively small areas of contamination were found in the exterior grounds. The maximum radiation level measured was 0.7 mR/h at 1 cm. A relatively large area (approx. 0.8 acre) in the Back Forty area exhibited anomalous radiation levels. Radiation levels as high as 100 μR/h were measured at 3 ft above ground. This area was reportedly used as a dump site for Bureau of Mines activities. The structures, equipment, and material associated with the BioMass Facility can be released for unrestricted use. However, because of the subsurface contamination found in both the BioMass and the Back Forty areas, some restrictions should be incorporated into any planned useage for this site. Some discussion regarding these hazards are included in the text of this report

  8. Analysis of the current rib support practices and techniques in U.S. coal mines

    Institute of Scientific and Technical Information of China (English)

    Mohamed Khaled M.; Murphy Michael M.; Lawson Heather E.; Klemetti Ted

    2016-01-01

    Design of rib support systems in U.S. coal mines is based primarily on local practices and experience. A better understanding of current rib support practices in U.S. coal mines is crucial for developing a sound engineering rib support design tool. The objective of this paper is to analyze the current practices of rib control in U.S. coal mines. Twenty underground coal mines were studied representing various coal basins, coal seams, geology, loading conditions, and rib control strategies. The key findings are:(1) any rib design guideline or tool should take into account external rib support as well as internal bolting;(2) rib bolts on their own cannot contain rib spall, especially in soft ribs subjected to significant load—external rib control devices such as mesh are required in such cases to contain rib sloughing;(3) the majority of the studied mines follow the overburden depth and entry height thresholds recommended by the Program Information Bulletin 11-29 issued by the Mine Safety and Health Administration;(4) potential rib insta-bility occurred when certain geological features prevailed—these include draw slate and/or bone coal near the rib/roof line, claystone partings, and soft coal bench overlain by rock strata;(5) 47%of the stud-ied rib spall was classified as blocky—this could indicate a high potential of rib hazards;and (6) rib injury rates of the studied mines for the last three years emphasize the need for more rib control management for mines operating at overburden depths between 152.4 m and 304.8 m.

  19. The U.S. Bureau of Reclamation's use of Climate Information Products to support Reservoir Operations and Water Management

    Science.gov (United States)

    Brekke, L. D.

    2007-12-01

    Climate forecast information plays an integral role in Reclamation's operation of surface water systems located throughout the western United States. These systems include over 300 reservoirs, 16000 miles of canals, and 245 million acre-feet of storage capacity. Combined, their operation leads to approximately $9 billion in annual agricultural benefits, enough energy to supply 6 million homes, 308 public recreation areas, and billions of dollars in avoided flood damages. Reclamation's use of climate information varies with decision application, which might be characterized by lead- time, application horizon, and reversibility. This presentation will provide an overview of Reclamation's short- to long-term climate-affected decisions, where and why climate information products are currently used, where products are desired but are absent, and where products are available but are not used for various reasons. The presentation will also highlight lessons learned from recent efforts to introduce new uses of climate forecast information in Reclamation decision processes (e.g., use of short-lead teleconnections to potentially support Spring season flood control management in the Pacific Northwest, use of CPC local 3-month temperature outlooks to support Summer-Autumn stream temperature management in California, and development of downscaled WCRP CMIP3 climate projections to support long-term system evaluations throughout Reclamation's service regions).

    Full Text Available Former coal mining sites have always raised environmental and economic challenges for the areas where they were located, especially for those communities that were highly dependent on the coal mining industry. The present paper will explore the factors leading to the decline of coal mining industry in Romania and State of Michigan, U.S., the social, economic and environmental impact that occurred after closing coal extractions and the approaches that the two states took to reconstruct the economy of the former mining areas. The paper attempts to make recommendations of financial incentives that can be used to foster the economic redevelopment of former coal mining sites in Romania.

  2. Hydrogeology and hydrochemistry of the midnite mine, northeastern Washington. Report of investigations/1994

    International Nuclear Information System (INIS)

    The Midnite Mine is an inactive, hardrock uranium mine on the Spokane Indian Reservation, Stevens County, WA. Oxidation of sulfide-containing minerals, primarily pyrite, in the ore body produces large quantities of acidic water. An interception system installed by the mining company limits the discharge of contaminated water from the mine. The Bureau of Indian Affairs and the Bureau of Land Management have been actively involved in planning remediation of the disturbed areas. To assist in remediation, the U.S. Bureau of Mines initiated research to determine water quality and define groundwater flow characteristics. Bureau personnel designed a monitoring network, supervised installation of sampling wells, and collected and analyzed water samples. This Report of Investigations describes interpretation of data collected between December 1989 to April 1992

  9. Formerly utilized MED/AEC sites Remedial Action Program. Radiological survey of the Albany Metallurgical Research Center, United States Bureau of Mines, Albany, Oregon

    International Nuclear Information System (INIS)

    During the periods 1954 to 1956 and 1960 to 1971, the Albany Metallurgical Research Center (AMRC) was engaged in metallurgical operations that included melting, machining, welding, and alloying of thorium. In addition, research on alloys of uranium and thorium started in 1955 and continued until suspended in 1978. Records indicated that at the time the original AEC contract was terminated, buildings and surrounding areas were decontaminated to the general guidelines provided by the AEC. Those guidelines were not as specific as current guidelines, and detailed records of the final decontamination were not documented. Because of that, radiological assessemnt of this site was initiated in June 1978. During June and July 1978, a radiological survey of the grounds and the buildings was completed. Certain buildings were designated as areas where no survey was necessary; however, it was decided by the ANL survey team to at least perform floor surveys in those buildings. Significant levels of contamination, both loose and fixed, were found in 10 of the 33 buildings surveyed. In addition, about 60 contaminated areas, including 17 with loose contamination, were found outside the buildings. Surveys of the sanitary sewers, the Albany sewage treatment plant and the Ohling Farm showed no significant contamination. Significant levels of contamination were found in the septic system behind Buildings 12 and 17. Air samples taken throughout the site revealed no radon concentrations in excess of the limits proposed by the US Surgeon General (10 CFR 712)

  11. Comparative study on efficiency performance of listed coal mining companies in China and the US

    International Nuclear Information System (INIS)

    Continually rising energy prices in global markets highlights a serious concern about the need to improve energy efficiency and the efficiency in energy sector in many countries. China, as one of the fastest growing countries in the world and the largest coal producer, has high coal consumption but a low recovery rate of coal utilization. Coal efficiency and the efficiency in coal industry have therefore attracted a great deal of attention from Chinese policy makers, coal firms and academics. This study attempts to compare the relative technical efficiency performance of listed coal mining companies in China and the US using CCR and BCC models in the advanced DEA linear programming. The results show that the level of relative efficiency in Chinese coal mining enterprises, regardless of total technical efficiency or decomposed pure technical and scale efficiency, is much lower than in American coal firms. The study also highlights the input resources that cause the inefficiency of Chinese coal mining companies. Furthermore, in-depth discussion and analysis of how the institutional environments of the two countries could cause the differences are provided. (author)

    Our paper analyzes the sources of labor productivity variation in U.S. bituminous coal surface mining from 1960 to 1976. The coal mining industry was among the first to experience a prolonged decline in labor productivity in the post-World War II period. In surface mining nationally, labor productivity in 1977 was 26.6 tons per worker-day, or 28 percent less than the peak of 36.7 tons per worker-day achieved in 1973. Moreover, in several major coal-producing states, the decline began much ear...

    Finnie, Bruce; Stuart, Jeffrey; Gibson, Linda; Zabriskie, Fern

    2009-09-01

    Mandatory insurance requirements and/or mitigation fees (royalties) for mining companies may help reduce environmental risk exposure for the federal government. Mining is examined since the Environmental Protection Agency (EPA) Toxic Release Inventory reveals that this sector produces more hazardous waste than any other industrial sector. Although uncommon, environmental expense can exceed hundreds of millions of dollars per development. Of particular concern is the potential for mines to become unfunded Superfund sites. Monte Carlo simulation of risk exposure is used to establish a plausible range of unfunded federal liabilities associated with cyanide-leach gold mining. A model is developed to assess these costs and their impact on both the federal budget and corporate profitability (i.e., industry sustainability), particularly if such costs are borne by offending firms.

  1. US uranium mining: No rebound in sight

    International Nuclear Information System (INIS)

    US uranium production has fallen eight-fold in the last decade with no rebound in sight, says former industry executive J.R. Wolcott of Denver, Colorado. Production has dropped from more than 40 million pounds per year in 1980 to less than 5 million pounds, and the price has skidded from a high of $40 per pound in the late 1950s to less than $8 today, Wolcott notes. The cause of the dramatic turnaround is rather simple: The military no longer buys uranium, leaving commercial nuclear power as the only customer, and no new nuclear power plants have been ordered in 15 years. Adding to these dismal circumstances is the low quality of US ore deposits, a compared to the rich deposits found overseas. open-quotes All in all,close quotes Wolcott says, open-quotes world markets are awash with uranium. The United States is unlikely to regain its former position as a major supplier.close quotes Wolcott is not convinced the former Soviet Union's entry into the international uranium market has been a major factor in the US decline, despite charges of open-quotes dumpingclose quotes by the former Soviet states. Regardless of the outcome of the open-quotes dumpingclose quotes charges, he says, open-quotes The realistic outlook is for a continuation of a small domestic uranium industry, perhaps near its present level.

  7. Mine-fire diagnostics applied to the Carbondale, Pennsylvania mine-fire site. Rept. of Investigations/1992

    International Nuclear Information System (INIS)

    The U.S. Bureau of Mines applied its mine fire diagnostic method to an abandoned anthracite mine fire site in Carbondale, Lackawanna County, PA. The technique to locate fires in abandoned coal mines and coal refuse piles includes the determination of hydrocarbon concentrations in mine gases, the imposition of an underground gas flow direction, and use of a surface mapping method, to define heated and cold zones in underground coal strata. The heated zones at Carbondale were characterized by elevated methane concentrations. The results of 25 communication tests were analyzed to define 2 large (approximately 100 by 250 ft) and 5 small, isolated heated zones. An approximate correlation existed between the location of the heated zones and areas of anomalous snow melt. The correlation between the results of the diagnostic test and subsurface temperatures was not significant

  8. US uranium mining industry: background information on economics and emissions

    International Nuclear Information System (INIS)

    A review of the US uranium mining industry has revealed a generally depressed industry situation. The 1982 U3O8 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 U3O8 production for the years 1983 and 1990. Reactor fuel demand is estimated to increase from 15,900 tons to 21,300 tons U3O8 respectively. U3O8 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 222Rn emission levels for a group of 27 uranium mines. It is shown that 222Rn 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 222Rn emissions is predicted due to 17 of the mines being shutdown and sealed. The estimated total 222Rn 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

  14. Characterization and effectiveness of remining abandoned coal mines in Pennsylvania

    International Nuclear Information System (INIS)

    Under an approved remining program, mine operators can remine abandoned coal mines without assuming legal responsibility for treatment of the previously degraded water, as long as the discharging waters are not further degraded and other regulatory requirements are satisfied. A US Bureau of Mines review of 105 remining permits in Pennsylvania indicates that remining results in substantial reclamation of abandoned mine lands, utilization of significant quantities of coal, and reduction of contaminant loads (acidity and iron) from degraded mine drainage discharges. Normality tests performed on the water quality and flow data indicate generally nonnormal distributions and extreme right-skewness tending toward lower values. The water quality of underground coal mines was observed to be more highly degraded in terms of acidity, iron, and sulfate than that of surface coal mines. The optimum baseline sampling scenario is 12 months in duration at a frequency of one sample per month. Analysis of water quality and flow rates before and after remining indicates that a majority of the mines exhibited either no change or a significant decrease in pollution rate because of remining. The discharge flow rate was the dominant controlling factor when the post-remining contaminant load was significantly better or worse than the baseline (pre-mining) load

  16. Response of surface springs to longwall coal mining Wasatch Plateau, Utah

    International Nuclear Information System (INIS)

    High-extraction longwall coal mining creates zones in the overburden where strata bend, fracture, or cave into the mine void. These physical alterations to the overburden stratigraphy have associated effects on the hydrologic regime. The US Bureau of Mines (SBM) studied impacts to the local hydrologic system caused by longwall mining in the Wasatch Plateau, Utah. Surface springs in the vicinity of two coal mines were evaluated for alterations in flow characteristics as mining progressed. Fourteen springs located above the mines were included in the study. Eight of the springs were located over longwall panels, four were located over barrier pillars and mains, and two ere located outside the area disturbed by mining. Flow hydrographs for each spring were compared to climatic data and time of undermining to assess if mining in the vicinity had influenced flow. Heights of fracturing and caving in the overburden resulting from seam extraction were calculated using common subsidence formulas, and used in conjunction with elevations of springs to assess if fracturing influenced the water-bearing zones studied. One spring over a panel exhibited a departure from a normally-shaped hydrograph after being undermined. Springs located over other mine structures, or outside the mine area did not show discernible effects from mining. The limited response of the springs was attributed to site-specific conditions that buffered mining impacts including the elevation of the springs above the mine level, and presence of massive sandstones and swelling clays in the overburden materials

    In the speakers' bureau system, physicians are recruited and trained by pharmaceutical, biotechnology, and medical device companies to deliver information about products to other physicians, in exchange for a fee. Using publicly available disclosures, we assessed the thesis that speakers' bureau involvement is not a feature of academic medicine in Canada, by estimating the prevalence of participation in speakers' bureaus among Canadian faculty in one medical specialty, cardiology. We analyzed the relevant features of an actual contract made public by the physician addressee and applied the Canadian Medical Association (CMA) guidelines on physician-industry relations to participation in a speakers' bureau. We argue that speakers' bureau participation constitutes a form of peer selling that should be understood to contravene the prohibition on product endorsement in the CMA Code of Ethics. Academic medical institutions, in conjunction with regulatory colleges, should continue and strengthen their policies to address participation in speakers' bureaus. PMID:24348883

This is effect enhanced by the mining operation, and creates new challenges in relationship between the mining and local community. The purpose of this project are developed the Stakeholders engagement evaluation plan which is currently developed in University of Nevada, Reno for the Emigrant mining project, located in the central Nevada, USA, and belong to the Newmont Mining Corporation, one of the gold production leader worldwide. The needs for this project is to create the open dialog between Newmont mining company and all interested parties which have social or environmental impacts from the Emigrant mine. Identification of the stakeholders list is first and one of the most difficult steps in the developing of mine social responsibility. Stakeholders' engagement evaluation plan must be based on the timing and available resources of the mining company, understanding the goals for the engagement, and on analyzes of the possible risks from engagement. In conclusion, the Stakeholders engagement evaluation plan includes: first, determinations of the stakeholders list, which must include any interested or effected by the mine projects groups, for example: state and local government representatives, people from local communities, business partners, environmental NGOs, indigenous people, and academic groups. The contacts and availability for communication is critical for Stakeholders engagement. Next, is to analyze characteristics of all these parties and determinate the level of interest and level of their influence on the project. The next step includes the Stakeholders matrix and mapping development, where all these information will be put together.After that, must be chosen the methods for stakeholders' engagement. The methods usually depends from the goals of engagement (create the dialog lines, collect the data, determinations of the local issues and concerns, or establish

  19. Overview of solution mining

    International Nuclear Information System (INIS)

    This paper deals with in situ solution mining. A significant fraction of known U.S. uranium reserves occur as low grade mineralization in sedimentary sandstone deposits located between 40 and 200 meters subsurface. For a variety of reasons, such deposits may not be economically developable by any method other than in situ solution mining. This coupled with the current market price of uranium has led to significant development and application of in situ solution mining for uranium production during the past several years. The process consists of the ore body; well field; lixiviant; uranium recovery process; waste treatment processes; and aquifer restoration. A tabulation of firms involved with a summary of the leach chemistry used is given. 3 refs

    2016-04-01

    The recently reorganized GGOS Bureau of Networks and Observations has many elements that are associated with building and sustaining the infrastructure that supports the Global Geodetic Observing System (GGOS) through the development and maintenance of the International Terrestrial and Celestial Reference Frames, improved gravity field models and their incorporation into the reference frame, the production of precision orbits for missions of interest to GGOS, and many other applications. The affiliated Service Networks (IVS, ILRS, IGS, IDS, and now the IGFS and the PSMSL) continue to grow geographically and to improve core and co-location site performance with newer technologies. Efforts are underway to expand GGOS participation and outreach. Several groups are undertaking initiatives and seeking partnerships to update existing sites and expand the networks in geographic areas void of coverage. New satellites are being launched by the Space Agencies in disciplines relevant to GGOS. Working groups now constitute an integral part of the Bureau, providing key service to GGOS. Their activities include: projecting future network capability and examining trade-off options for station deployment and technology upgrades, developing metadata collection and online availability strategies; improving coordination and information exchange with the missions for better ground-based network response and space-segment adequacy for the realization of GGOS goals; and standardizing site-tie measurement, archiving, and analysis procedures. This talk will present the progress in the Bureau's activities and its efforts to expand the networks and make them more effective in supporting GGOS.

  1. Conventional uranium mining in the United States: US energy gears up to meet the challenge

    International Nuclear Information System (INIS)

    For more than 200 years, the United States has been proud of almost 100 percent self-sufficiency in terms of natural resources. With the advent of the new global economy came the availability of new sources of raw materials and products. Suddenly, US industries were obliged to take the survival-of-the-fittest test. The uranium industry was one such industry and it suffered from the availability of lower-cost uranium from other countries. As such, the US uranium industry was declared non-viable. Today, the modest amount of uranium comes from unconventional mines. This article focuses on one US uranium mining company, the US Energy Corp, which promises to begin conventional mining and milling as soon as the uranium market permits. The article contains a brief review of the industry and an in-depth review of several uranium mining projects in the United States

    The Exclusive Economic Zone (EEZ) declared by President Reagan in March 1983 has met with a mixed response from those who would benefit from a guaranteed, 200-nautical-mile (370-km) protected underwater mining zone off the coasts of the United States and its possessions. On the one hand, the U.S. Department of the Interior is looking ahead and has been very successful in safeguarding important natural resources that will be needed in the coming decades. On the other hand, the mining industry is faced with a depressed metals and mining market.A report of the Exclusive Economic Zone Symposium held in November 1983 by the U.S. Geological Survey, the Mineral Management Service, and the Bureau of Mines described the mixed response as: “ … The Department of Interior … raring to go into promotion of deep-seal mining but industrial consortia being very pessimistic about the program, at least for the next 30 or so years.” (Chemical & Engineering News, February 5, 1983).

  7. The use of constructed wetlands in the treatment of acid mine drainage

    International Nuclear Information System (INIS)

    US government regulations require that all effluents from industrial operations, including mining, meet certain water quality standards. Constructed wetlands have proven to be useful in helping to attain those standards. Application of this biotechnology to mine water drainage can reduce water treatment costs and improve water quality in streams and rivers adversely affected by acidic mine water drainage from abandoned mines. Over 400 constructed wetland water treatment systems have been built on mined lands largely as a result of research by the US Bureau of Mines. Wetlands are passive biological treatment systems that are relatively inexpensive to construct and require minimal maintenance. Chemical treatment costs are reduced sufficiently to repay the cost of construction in less than a year. The mine waste water is typically treated in a series of excavated ponds that resemble small marsh areas. The ponds are engineered to facilitate bacterial oxidation of iron. Ideally, the water then flows through a composted organic substrate supporting a population of sulphate-reducing bacteria which raises the pH. Constructed wetlands in the USA are described - their history, functions, construction methodologies, applicabilities, limitations and costs. (author). 26 refs, 2 figs

    Taylor, D.A.R. [Bat Conservation International, Austin, TX (United States)

    1995-06-01

    Abandoned underground mines in North America provide a habitat for bats. Closure of mines without conducting biological surveys can endanger bat species that are abundant. The North American Bats and Mines Project (NABMP) has been created by the U.S. Bureau of Land Management and Bat Conservation International to provide coordination among government and conservation organizations and the mining industry in order to minimize the loss of bats living in mines. NABMP provides coordination through education on the importance of mines for bat populations by providing training on mine assessment and closure methods, by assisting with protection and improvement of abandoned mine roosts, and by developing methods for creating new bat habitat. 1 tab.

  14. A state geological survey commitment to environmental geology - the Texas Bureau of Economic Geology

    International Nuclear Information System (INIS)

    In several Texas environmental laws, the Bureau of Economic Geology is designated as a planning participant and review agency in the process of fulfilling environmental laws. Two examples are legislation on reclamation of surface mines and regulation of processing low level radioactive wastes. Also, the Bureau is the principal geological reviewer of all Environmental Assessments and Environmental Impact Statements which the Office of the Governor circulates for state review on all major developmental activities in Texas. The BEG continues its strong interest in environmental geology. In February 1988, it recommitted its Land Resources Laboratory, initiated in 1974, toward fulfilling needs of state, county, and city governments for consultation and research on environmental geologic problems. An editorial from another state geological survey would resemble the about description of texas work in environmental geology. State geological surveys have led federal agencies into many developments of environmental geology, complemented federal efforts in their evolution, and continued a strong commitment to the maintenance of a quality environment through innovative geologic studies

  15. The thermoluminscent dosimetry service of the radiation protection bureau

    International Nuclear Information System (INIS)

    Thermoluminescent materials have been used in radiation dosimetry for many years, but their application to nationwide personnel dosimetry has been scarce. An undertaking of this nature requires that methods be established for identification of dosimeters and for fast interpretation and communication of dose to the users across the country. It is also necessary that records of cumulative dose of individual radiation workers be continuously updated, and such records be maintained for a prolonged period. To do this many problems pertinent to associated equpment, vis. the computer, TL reader, their interfacing, and to the operational procedures of the service had to be resolved. Since April 1977, the Radiation Protection Bureau has been providing a Thermoluminescent Dosimetry Service to Canadian radiation workers. This document describes the RPB dosimeter, its characteristics, various aspects of the service, objectives of the service, and how the objective goals of the service are achieved. (auth)

  19. Development of a new methodology for mitigating acid mine drainage (AMD) at reclaimed surface mines

    International Nuclear Information System (INIS)

    A 1.2 hectare (ha) experimental site located on a 14.5 ha reclaimed surface mine in Greene County, PA was injected with a 141 cubic meters (m3) of fly ash and fluidized bed combustion (FBC) ash grout that included acid mine drainage (AMD) sludge. An evaluation of this AMD abatement approach by the Bureau of Mines found that the average net acidity and concentrations of several metal ions at the discharge seep and monitoring wells decreased after grouting. Changes in metal concentrations were assumed to be related to alkaline addition and/or encapsulation. Initial results indicate that this technique is potentially an effective AMD abatement method

    2011-01-01

    The Cactus Queen Mine is located in the western Mojave Desert in Kern County, California. The Cactus Queen gold-silver (Au-Ag) deposit is similar to other Au-Ag deposits hosted in Miocene volcanic rocks that consist of silicic domes and associated flows, pyroclastic rocks, and subvolcanic intrusions. The volcanic rocks were emplaced onto a basement of Mesozoic silicic intrusive rocks. A part of the Cactus Queen Mine is located on Federal land managed by the U.S. Bureau of Land Management (BLM). Staff from the BLM initially sampled the mine area and documented elevated concentrations of arsenic (As) in tailings and sediment. BLM then requested that the U.S. Geological Survey (USGS), in collaboration with Chapman University, measure and characterize As and other geochemical constituents in sediment, tailings, and waters on the part of the mine on Federal lands. This report is made in response to the request by the BLM, the lead agency mandated to conduct a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) - Removal Site Investigation (RSI). The RSI applies to the potential removal of As-contaminated mine waste from the Cactus Queen Mine as a means of reducing As release and exposure to humans and biota. This report summarizes data obtained from field sampling of sediments, mine tailings, and surface waters at the Cactus Queen Mine on January 27, 2008. Our results provide a preliminary assessment of the sources of As and associated chemical constituents that could potentially impact humans and biota.

  3. Geophysical void detection at the site of an abandoned limestone quarry and underground mine in southwestern Pennsylvania

    International Nuclear Information System (INIS)

    Locating underground voids, tunnels, and buried collapse structures continues to present a difficult problem for engineering geoscientists charged with this responsibility for a multitude of different studies. Solutions used and tested for void detection have run the gamut of surface geophysical and remote sensing techniques, to invasive trenching and drilling on closely-spaced centers. No where is the problem of locating underground voids more ubiquitous than in abandoned mined lands, and the U.S. Bureau of Mines continues to investigate this problem for areas overlying abandoned coal, metal, and nonmetal mines. Because of the great diversity of resources mined, the problem of void detection is compounded by the myriad of geologic conditions which exist for abandoned mined lands. At a control study site in southwestern Pennsylvania at the Bureau's Lake Lynn Laboratory, surface geophysical techniques, including seismic and other methods, were tested as a means to detect underground mine voids in the rather simple geologic environment of flat-lying sedimentary strata. The study site is underlain by an abandoned underground limestone mine developed in the Wymps Gap Limestone member of the Mississippian Mauch Chunk Formation. Portals or entrances into the mine, lead to drifts or tunnels driven into the limestone; these entries provided access to the limestone where it was extracted by the room-and-pillar method. The workings lie less than 300 ft from the surface, and survey lines or grids were positioned over the tunnels, the room-and-pillar zones, and the areas not mined. Results from these geophysical investigations are compared and contrasted. The application of this control study to abandoned mine void detection is apparent, but due to the carbonate terrain of the study site, the results may also have significance to sinkhole detection in karst topography

  6. Review of samples of tailings, soils and stream sediment adjacent to and downstream from the Ruth Mine, Inyo County, California

    Science.gov (United States)

    Rytuba, James J.; Kim, Christopher S.; Goldstein, Daniel N.

    2011-01-01

    The Ruth Mine and mill are located in the western Mojave Desert in Inyo County, California (fig. 1). The mill processed gold-silver (Au-Ag) ores mined from the Ruth Au-Ag deposit, which is adjacent to the mill site. The Ruth Au-Ag deposit is hosted in Mesozoic intrusive rocks and is similar to other Au-Ag deposits in the western Mojave Desert that are associated with Miocene volcanic centers that formed on a basement of Mesozoic granitic rocks (Bateman, 1907; Gardner, 1954; Rytuba, 1996). The volcanic rocks consist of silicic domes and associated flows, pyroclastic rocks, and subvolcanic intrusions (fig. 2) that were emplaced into Mesozoic silicic intrusive rocks (Troxel and Morton, 1962). The Ruth Mine is on Federal land managed by the U.S. Bureau of Land Management (BLM). Tailings from the mine have been eroded and transported downstream into Homewood Canyon and then into Searles Valley (figs. 3, 4, 5, and 6). The BLM provided recreational facilities at the mine site for day-use hikers and restored and maintained the original mine buildings in collaboration with local citizen groups for use by visitors (fig. 7). The BLM requested that the U.S. Geological Survey (USGS), in collaboration with Chapman University, measure arsenic (As) and other geochemical constituents in soils and tailings at the mine site and in stream sediments downstream from the mine in Homewood Canyon and in Searles Valley (fig. 3). The request was made because initial sampling of the site by BLM staff indicated high concentrations of As in tailings and soils adjacent to the Ruth Mine. This report summarizes data obtained from field sampling of mine tailings and soils adjacent to the Ruth Mine and stream sediments downstream from the mine on June 7, 2009. Our results permit a preliminary assessment of the sources of As and associated chemical constituents that could potentially impact humans and biota.

    近两年,属地化地勘单位分类改革的步伐不断加快,取得了不同程度的新进展。但是中央管理的地勘单位分类改革,还面临政策上的不确定,目前仍以探索为主。中国冶金地质总局从自身实际出发,基于必要性与可行性以及改革发展的目标,作出“转企改制、打造矿业集团”的选择,以地质勘查为基础、着眼于生态文明建设、相关产业多元化、事企分体运行,坚定不移地向前推进。就打造矿业集团而言,除了竞争激烈的市场环境问题,主要还是自身的短板问题,传统的思想观念、行为方式,现有的资金、人才、技术、管理经验和开放程度等,与实现理想中的蓝图还有很大差距。%For over two years, with a rapidly increasing pace of classification reform of geological prospecting units after localized management, we have made different degrees of new progress in this regard. However, at present, due to policy uncertainty, the classiifcation reform of geological exploration units administrated by the central government must be the focus of our efforts to research. This paper introduces the practice that has been done by China Metallurgical Geology Bureau. These practice include:based on the necessity and feasibility, as well as the aim of reforming and developing, they have chosen the path of restructuring and transformation with a view to creating mining group. At the same time, they have devoted their efforts to promoting ecological progress, seeking multiple developments of relevent industries, running institutions separately from enterprises in an unswervingly manner. Finally, this paper gives some suggestions for building mining group. It points out that in addition to the competitive market environment that we face, we need to pay attention to our own"short board", the traditional ideological concept and mode of behavior, the existing money, talents, technology, managerial

The investigation was in response to an abatement notification from the California Central Valley Regional Water Quality Control Board to evaluate the release of Hg from the Clyde and Elgin mines. Samples of water, sediment, and biota (aquatic macroinvertebrates) were collected from sites upstream and downstream from the two mine sites to evaluate the level of Hg contamination contributed by each mine to the aquatic ecosystem. Physical parameters, as well as dissolved organic carbon, total Hg (HgT), and MMeHg were analyzed in water and sediment. Other relevant geochemical constituents were analyzed in sediment, filtered water, and unfiltered water. Samples of aquatic macroinvertebrates from each mine were analyzed for HgT and MMeHg. The presence of low to moderate concentrations of HgT and MMeHg in water, sediment, and biota from the Freshwater Branch of Sulphur Creek, and the lack of significant increases in these concentrations downstream from the Clyde Mine indicated that this mine is not a significant source of Hg to the watershed during low flow conditions. Although concentrations of HgT and MMeHg were generally higher in samples of sediment and water from the Elgin Mine compared to the Clyde Mine, concentrations in comparable biota from the two mine areas were similar. It is likely that highly saline effluent from nearby hot springs contribute more Hg to the West Fork of Sulphur Creek than the mine waste material at the Elgin Mine.

  11. National Bureau of Standards Cold Neutron Research Facility

    International Nuclear Information System (INIS)

    In 1984 a National Academy of Sciences committee was set up to review the need for major facilities in the area of materials and condensed matter science. The report specifically mentioned the National Bureau of Standards Reactor (NBSR) as one of the places that should develop a cold neutron research facility (CNRF). NBS was able to obtain funding from congress to develop the NBS CNRF. The facility will cost approximately $25,000,000, including the guide hall, ten major instruments, and eight guide tubes. The cost does not include the cold source itself, which was funded separately. The cold source configuration is shown. This project has been funded to provide a national center for neutron research. Some fraction (one-third to two-thirds) of all the new facilities will be made available to outside users at no charge. The facilities will be staffed adequately to provide needed assistance to outside users to assure that they can perform their experiments effectively and efficiently. The prioritization of outside proposals will be performed by an independent review committee that will base their recommendations on the scientific merit of each proposal

  17. Disposing of coal combustion residues in inactive surface mines: Effects on water quality

    International Nuclear Information System (INIS)

    The disposal of coal combustion residues (CCR) in surface and underground coal mines can provide a stable, low-maintenance alternative to landfills, benefiting the mining and electric power industries. The material may be able to improve water quality at acid generating abandoned or reclaimed coal mine sites. Most combustion residues are alkaline, and their addition to the subsurface environment could raise the pH, limiting the propagation of pyrite oxidizing bacteria and reducing the rate of acid generation. Many of these CCR are also pozzolanic, capable of forming cementitious grouts. Grouts injected into the buried spoil may decrease its permeability and porosity, diverting water away from the pyritic material. Both mechanisms, alkaline addition and water diversion, are capable of reducing the amount of acid produced at the disposal site. The US Bureau of Mines is cooperating in a test of subsurface injection of CCR into a reclaimed surface mine. Initially, a mixture of fly ash, lime, and acid mine drainage (AMD) sludge was injected. Lime was the source of calcium for the formation of the pozzolanic grout. Changes in water quality parameters (pH, acidity, anions, and trace metals) in water samples from wells and seeps indicate a small but significant improvement after CCR injection. Changes in the concentration of heavy metals in the water flowing across the site were apparently influenced by the presence of flyash

  18. Intercomparison of radon and decay product measurements in an underground mine and EPA radon laboratory: A study organized by the IAEA International Radon Metrology Programme

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency (IAEA) in Vienna and the European Union (EU) in Bruxelles formed the International Radon Metrology Programme. The IRMP is designed to assess and foster the improvement of radon and decay product measurements that are made around the world. Within the framework of the IRMP, the U.S. Environmental Protection Agency Radiation and Indoor Environments National Laboratory (EPA) in Las Vegas, Nevada, organized jointly with the U.S. Bureau of Mines an international intercomparison exercise at a former uranium mine (Twilight Mine, Colorado) and the EPA Radon Laboratory. The main objective of this exercise was to compare radon and radon decay product instruments under both well-controlled as well as widely fluctuating exposure conditions. The laboratory exposures occurred under relatively steady radon and decay product conditions, with a moderate equilibrium ratio, while the conditions in the mine fluctuated greatly and the equilibrium ratio was low. An additional purpose of the exercise was to provide a forum for manufacturers and measurement organizations worldwise to exchange information and plan improvements in their operations and calibration programs. Altogether 19 organizations from seven countries intercomparing 32 different radon and radon decay product instruments participated in this exercise. This paper summarizes the results from the analysis of the experimental data obtained in the Bureau of Mines Twilight Mine in July of 1994, as well as the results from the EPA Radon laboratory in August of 1994

    1996-12-31

    Comparison of the Armenia and US systems of coal resource and reserve calculation indicates that the methodologies used are remarkably similar. The terminology is different, thus leading to confusion, but the methods used to calculate tonnages are virtually the same. The resource/reserve system used in the US is based upon that developed at the US Geological Survey (USGS) and the former US Bureau of Mines. Standards within Armenia were developed by the Ministry of Geology of the former USSR. Both systems classify coal resources/reserves in accordance to the degree of geologic control and economic feasibility of recovery.

    Full Text Available A group of Minnesota architects created the ASHSB in 1914 to provide a solution for theshortage of middle class housing in the U.S. By 1919, the bureau had offices throughout the U.S. and received the endorsement of both the American Institute of Architects and the Department of Commerce. During this time, the members of the Bureau produced hundreds of plan sets and monthly bulletins to assist homeowners with their housing choices. The monthly magazine The Small Home, in conjunction with the published plan books--Your Future Home and How to Plan, Finance, and BuildYour Home--dispensed valuable information to potential homebuyers across the nation. To date, one master’s thesis (Lisa Schrenk, University of Virginia 1990 and an article (Thomas Harvey, 1991 have been written about the ASHSB. Neither one discussed the relationship of this group with the AIA, a keyendorsement agency.This research involved extensive archival research at the AIA. Records from the early 20th century were analyzed to determine the relationship between the AIA and the ASHSB in the early 20th century. This relationship provides insight into the current lack of architectural involvement in single-family house design today. The single most prevalent building type in the U.S. is the single-family house, yet architects are little involved in the design of most of them. Architects have the ability and training to create sustainable, affordable, and well-design single-family houses and yet they do not. This paper seeks to provide one explanation through the interpretation of the historic relationship of the AIA to the ASHSB.

    2011-01-01

    Background and Objectives The Little Bonanza mercury (Hg) mine, located in San Luis Obispo County, California, is a relatively small mine with, a historical total Hg production of about 1,000 flasks. The mine workings and tailings are located in the headwaters of the previously unnamed west fork of Las Tablas Creek (WF Las Tablas Creek), which flows into the Nacimiento Reservoir. Wasterock and tailings eroded from the Little Bonanza Hg Mine have contributed Hg-enriched mine wastes to the headwaters of WF Las Tablas Creek. The mine is located on Federal land managed by the U.S. Bureau of Land Management (BLM), which requested that the U.S. Geological Survey (USGS) measure and characterize Hg and other geochemical constituents in tailings, sediment, water, and biota at and downstream from the minesite. This report is in response that request, from the lead agency which is mandated to conduct a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) - Removal Site Investigation (RSI). The RSI applies to removal of Hg-contaminated mine waste from the Little Bonanza minesite as a means of reducing Hg transport to WF Las Tablas Creek. This report summarizes data obtained from field sampling of mine tailings, wasterock, sediment, water, and biota at the Little Bonanza Mine that was completed on April 6, 2010. Conditions during sampling were dry and no rain had occurred in the watershed for several weeks. Our results permit a preliminary assessment of the mining sources of Hg and associated chemical constituents that could produce elevated levels of monomethyl mercury (MMeHg) in WF Las Tablas Creek and in biota.

    1980-05-01

    As part of a program to examine the ability of existing control technologies to meet federal guidelines for the quality of aqueous effluents from coal mines, an intensive study of water, coal, and overburden chemistry was conducted at a surface coal mine in Alabama from May 1976 through July 1977. Sampling sites included the pit sump, a stream downgrade from the mine, the discharge from the water treatment facility, and a small stream outside the mine drainage. Water samples were collected every two weeks by Argonne subcontractors at the Alabama Geological Survey and analysed for the following parameters: specific conductance, pH, temperature, acidity, bicarbonate, carbonate, chloride, total dissolved solids, suspended solids, sulfate, and 20 metals. Analysis of the coal and overburden shows that no potential acid problem exists at this mine. Water quality is good in both streams sampled, and high levels of dissolved elements are found only in water collected from the pit sump. The mine effluent is in compliance with Office of Surface Mining water quality standards.

    2015-01-01

    The Bureau of Land Management (BLM) has been actively expanding its capacity to work cooperatively with other agencies, Tribes, the public, and other stakeholders using collaborative and alternative dispute resolution (ADR) approaches. In 1997, the BLM created the BLM’s Collaboration and Alternative Dispute Resolution Program (Collaboration/ADR Program) to centralize, strengthen, and coordinate these efforts. Specifically, the Collaboration/ADR Program is charged with developing ADR policies; ensuring that statutory and regulatory requirements are met; and providing training, resources, and direct support for collaboration and ADR in the BLM. At the request of the Collaboration/ADR Program, the Policy Analysis and Science Assistance Branch of the U.S. Geological Survey, located in the Fort Collins Science Center, conducted an online survey of BLM employees in early 2013 to address four overarching questions: What information sources and assistance resources are BLM employees currently accessing to fill their conflict/dispute resolution and collaboration needs?

    Cantrell, B.K.; Williams, K.L.; Stein, S.W. [and others

    1996-12-31

    In June 1992, the Mine Safety and Health Administration (MSHA) published the Report of the Coal Mine Respirable Dust Task Group, Review of the Program to Control Respirable Coal Mine Dust in the United States. As one of its recommendations, the report called for the accelerated development of two mine dust monitors: (1) a fixed-site monitor capable of providing continuous information on dust levels to the miner, mine operator, and to MSHA, if necessary, and (2) a personal sampling device capable of providing both a short-term personal exposure measurement as well as a full-shift measurement. In response to this recommendation, the U.S. Bureau of Mines initiated the development of a fixed-site machine-mounted continuous respirable dust monitor. The technology chosen for monitor development is the Rupprecht and Patashnick Co., Inc. tapered element oscillating microbalance. Laboratory and in-mine tests have indicated that, with modification, this sensor can meet the humidity and vibration requirements for underground coal mine use. The U.S. Department of Energy Pittsburgh Research Center (DOE-PRC) is continuing that effort by developing prototypes of a continuous dust monitor based on this technology. These prototypes are being evaluated in underground coal mines as they become available. This effort, conducted as a joint venture with MSHA, is nearing completion with every promise of success.

  13. Environmental aspects of mining

    International Nuclear Information System (INIS)

    More soil is removed from the earth's surface nowadays by mining than by natural erosion from all of the world's rivers. Few people realise that mines and smelting works account for up to a tenth of our total energy consumption, and that mining leaves thousands of tons of waste behind; next to which, the everyday waste accumulated in towns worldwide almost pales into insignificance. The question is, can we really afford the price of our consumption of rawmaterials in terms of the consequential harm to our environment? New strategies and solution possibilities are discussed in the text. (orig./HP)

    The GGOS Bureau of Networks and Communications is being reorganized into the Bureau of Networks and Observations. Although the GGOS Bureau of Networks and Communication was the Bureau of the Services, it focused primarily on the geometric techniques (VLBI, SLR, GNSS, and DORIS) that provided the foundation for the development and maintenance of the International Terrestrial Reference Frame. Over the course of the last several years the Space Geodesy networks have grown; new systems are in the process of deployment, new sites are being established following the GGOS concept of "core" sites and new technologies are implemented to enhance performance in data yield as well as accuracy. In particular, several groups are undertaking initiatives and seeking partnerships to update existing sites and expand the networks in geographic areas void of coverage. It has also been long recognized that new data products generated by entities within and outside of GGOS will require integration with those of the geometric and non-geometric Service data in order to produce new and improved products such as a Unified Height System, improved tide and ocean models, and better hazard assessment tools. The role of the new Bureau is now being expanded to better integrate the non-geometric Services (Gravity Service, Tide gauge networks, etc.) and to strengthen communications with the space missions, the simulation activities to project network capability, and some of the data gathering functions. The expanded Bureau will include the GGOS Working Groups on Missions, Simulations, Data and Information Systems, and it will be tightly linked to the IERS Working Group on Survey and Co-location. The reorganized Bureau will now become the GGOS Bureau of Networks and Observations. This poster will outline the plan for the new Bureau and will give an update on the status of the ground networks that will participate as well as its other components.

  2. Detecting and characterizing coal mine related seismicity in the Western U.S. using subspace methods

    Science.gov (United States)

    Chambers, Derrick J. A.; Koper, Keith D.; Pankow, Kristine L.; McCarter, Michael K.

    2015-11-01

    We present an approach for subspace detection of small seismic events that includes methods for estimating magnitudes and associating detections from multiple stations into unique events. The process is used to identify mining related seismicity from a surface coal mine and an underground coal mining district, both located in the Western U.S. Using a blasting log and a locally derived seismic catalogue as ground truth, we assess detector performance in terms of verified detections, false positives and failed detections. We are able to correctly identify over 95 per cent of the surface coal mine blasts and about 33 per cent of the events from the underground mining district, while keeping the number of potential false positives relatively low by requiring all detections to occur on two stations. We find that most of the potential false detections for the underground coal district are genuine events missed by the local seismic network, demonstrating the usefulness of regional subspace detectors in augmenting local catalogues. We note a trade-off in detection performance between stations at smaller source-receiver distances, which have increased signal-to-noise ratio, and stations at larger distances, which have greater waveform similarity. We also explore the increased detection capabilities of a single higher dimension subspace detector, compared to multiple lower dimension detectors, in identifying events that can be described as linear combinations of training events. We find, in our data set, that such an advantage can be significant, justifying the use of a subspace detection scheme over conventional correlation methods.

  4. An analysis of injury claims from low-seam coal mines

    Energy Technology Data Exchange (ETDEWEB)

    Gallagher, S.; Moore, S.; Dempsey, P.G. [NIOSH, Pittsburgh, PA (United States)

    2009-07-01

    The restricted workspace present in low-seam coal mines forces workers to adopt awkward working postures (kneeling and stooping), which place high physical demands on the knee and lower back. This article provides an analysis of injury claims for eight mining companies operating low-seam coal mines during calendar years 1996-2008. All cost data were normalized using data on the cost of medical care (MPI) as provided by the U.S. Bureau of Labor Statistics. Results of the analysis indicate that the knee was the body part that led in terms of claim cost ($4.2 million), followed by injuries to the lower back ($2.7 million). While the average cost per injury for these body parts was $13,100 and $14,400, respectively (close to the average cost of an injury overall), the high frequency of these injuries resulted in their pre-eminence in terms of cost. Analysis of data from individual mining companies suggest that knee and lower back injuries were a consistent problem across companies, as these injuries were each among the top five most costly part of body for seven out of eight companies studied. Results of this investigation suggest that efforts to reduce the frequency of knee and low back injuries in low-seam mines have the potential to create substantial cost savings.

  7. Water quality changes at three reclaimed mine sites related to the injection of coal combustion residues

    International Nuclear Information System (INIS)

    Surface and groundwater pollution is a common problem associated with post-surface mining operations. The US Bureau of Mines (BOM) participated in the testing of subsurface injections of coal combustion residues (CCR) at three reclaimed surface mine sites. The addition of alkaline CCR to the subsurface environment can raise the pH, limit propagation of pyrite oxidizing bacteria and reduce the rate of acid generation. Many CCR's can also form cement-like grout, which when injected into buried spoil may decrease its permeability and porosity, diverting water away from the pyritic material. The objective of this work was to develop an effective, economical and permanent method to abate or reduce post-mining water pollution. The effectiveness of CCR injection as an acid mine drainage abatement technique was evaluated by the BOM by monitoring water quality at three sites in: Upshur County, WV, Clinton County, PA and Greene County, PA. Geophysical techniques were used at all sites to locate monitoring and injection wells that were subsequently drilled into the spoil. Grout injection work was completed between 1990 and 1994 at the three sites. Baseline water quality data were collected at all three sites for a minimum of one year. Post-grouting water quality at the discharge of the three sites showed a slight, long-term improvement and no apparent degradation in water quality resulting from the injection of the coal combustion residues. Notable and long-term improvements in water quality at various monitoring wells (on all sites) were also observed

  8. Treatment of mine waters discharged from underground uranium mines

    International Nuclear Information System (INIS)

    Contaminated mine water treatment before discharging into surface water streams is mandatory for the uranium mines within the National Uranium Company SA - Romania in order to limit supplementary exposure of the population living downside the mine sites. Present mine water treatment plants have to be upgraded in order to ensure the stringent limits for uranium and radium concentrations even when processing waters resulted from the mine flooding process. Ion exchange method is used for uranium removal while radium is separated by adsorption on activated carbon. Separation process and performance are presented for the water treatment plant at an active mine and at a closed mine. (author)

  11. KrasMAS: Implementation of a nuclear material computerized accounting system at the Mining and Chemical Combine through the Russian/US cooperative MPC and A program

    International Nuclear Information System (INIS)

    The Russian/US Mining and Chemical Combine (Gorno-Kimichesky Kombinat, GKhK, also referred to as Krasnoyarsk-26) Material Protection, Control and Accounting (MPC and A) project was initiated in June 1996. A critical component of the ongoing cooperative MPC and A enhancements at the GKhK is the implementation of a computerized nuclear material control and accountability (MC and A) system. This system must meet the MC and A requirements of the GKhK by integrating the information generated by numerous existing and new MC and A components in place at the GKhK (e.g., scales, bar-code equipment, NDA measurement systems). During the first phase of this effort, the GKhK adapted CoreMAS (developed at Los Alamos National Laboratory) for use in the PuO2 storage facility. This included formulation of Web-based user interfaces for plant personnel, Russification of the existing user interface, and at the functional level, modification of the CoreMAS stored procedures. The modified system is referred to as KrasMAS and builds upon completed work on CoreMAS. Ongoing efforts include adding GKhK specific report forms and expanding the functionality of the system for implementation at the radiochemical processing and reactor plants of the GKhK. Collaborations with other Russian facilities for appropriate parts of these efforts will be pursued

  12. Explicit modeling of rock mass discontinuities and mining subsidence simulation

    International Nuclear Information System (INIS)

    The US Bureau of Mines (USBM) is conducting research to define the probable mechanics of rock mass behaviour over longwall coal mines in Illinois. Horizontal discontinuities within the rock mass are systematically located using drill-core logs and rock mass ratings (RMR). A computer spreadsheet program is used to calculate a RMR, deformation modulus, and bending stiffness for each lithologic bed identified in a drill-core log. Lithologic beds with similar bending stiffness are grouped together to form blocks in a distinct-element computer model. The model simulates the plane strain response of a 900-meter-long 200-meter-thick slice of horizontally bedded sedimentary rock along the centerline of a 300-meter-wide longwall panel. The discontinuities between the blocks correlate with the locations of shear displacements measured in the field using time domain reflectometry (TDR). The research has shown the importance of incorporating the bedding structure of the rock mass and plastic sliding along discontinuities into any numerical model or analytic function that is intended to accurately simulate the behavior of horizontally bedded coal measure rocks. 16 refs., 4 figs., 2 tabs

  13. Investigation and characterization of mining subsidence in Kaiyang Phosphorus Mine

    Institute of Scientific and Technical Information of China (English)

    DENG Jian; BIAN Li

    2007-01-01

    In Kaiyang Phosphorus Mine, serious environmental and safety problems are caused by large scale mining activities in the past 40 years. These problems include mining subsidence, low recovery ratio, too much dead ore in pillars, and pollution of phosphorus gypsum. Mining subsidence falls into four categories: curved ground and mesa, ground cracks and collapse hole, spalling and eboulement, slope slide and creeping. Measures to treat the mining subsidence were put forward: finding out and managing abandoned stopes, optimizing mining method (cut and fill mining method), selecting proper backfilling materials (phosphogypsum mixtures), avoiding disorder mining operation, and treating highway slopes. These investigations and engineering treatment methods are believed to be able to contribute to the safety extraction of ore and sustainable development in Kaiyang Phosphorus Mine.

    2011-01-01

    About 1 million acres of Federal land in the Grand Canyon region of Arizona were temporarily withdrawn from new mining claims in July 2009 by the Secretary of the Interior because of concern that increased uranium mining could have negative impacts on the land, water, people, and wildlife. During a 2-year interval, a Federal team led by the Bureau of Land Management is evaluating the effects of withdrawing these lands for extended periods. As part of this team, the U.S. Geological Survey (USGS) conducted a series of short-term studies to examine the historical effects of breccia-pipe uranium mining in the region. The USGS studies provide estimates of uranium resources affected by the possible land withdrawal, examine the effects of previous breccia-pipe mining, summarize water-chemistry data for streams and springs, and investigate potential biological pathways of exposure to uranium and associated contaminants. This fact sheet summarizes results through December 2009 and outlines further research needs.

  17. Mineralogical characterization of mine waste

    International Nuclear Information System (INIS)

    Highlights: • Mineral characterization in mine waste is critical for prediction of metal leaching. • Analytical methods and examples are reviewed, including advanced techniques. • Quantitative mineralogy is described as a promising new method. • Example shows that understanding secondary arsenic minerals improves risk assessment. - Abstract: The application of mineralogical characterization to mine waste has the potential to improve risk assessment, guide appropriate mine planning for planned and active mines and optimize remediation design at closed or abandoned mines. Characterization of minerals, especially sulphide and carbonate phases, is particularly important for predicting the potential for acidic drainage and metal(loid) leaching. Another valuable outcome from mineralogical studies of mine waste is an understanding of the stability of reactive and metal(loid)-bearing minerals under various redox conditions. This paper reviews analytical methods that have been used to study mine waste mineralogy, including conventional methods such as X-ray diffraction and scanning electron microscopy, and advanced methods such as synchrotron-based microanalysis and automated mineralogy. We recommend direct collaboration between researchers and mining companies to choose the optimal mineralogical techniques to solve complex problems, to co-publish the results, and to ensure that mineralogical knowledge is used to inform mine waste management at all stages of the mining life cycle. A case study of arsenic-bearing gold mine tailings from Nova Scotia is presented to demonstrate the application of mineralogical techniques to improve human health risk assessment and the long-term management of historical mine wastes

    Siskind, D.E.; Stagg, M.S.; Wiegand, J.E.; Schulz, D.L.

    1994-12-31

    The mining industry and regulatory agencies have requested guidance on blasting near buried transmission pipelines and safe vibration levels. The U.S. Bureau of Mines and the State of Indiana cooperated with AMAX Coal Company and its consultants to determine the effects of coal mine overburden blasting on nearby pipelines. Five pressurized 76-m pipeline sections were installed on the Minnehaha Mine highwall near Sullivan, IN for testing to failure. Four 17- to 51-cm diameter welded steel pipes and one 20-cm PVC water pipe were monitored for vibration, strain, and pressure for a period of 6 months while production blasting advanced up to the pipeline field. In contrast to previous studies of small-scale close-in blasting for construction, these tests involved overburden blasts of up to 950 kg per delay in 31-cm blast-holes. Analyses found low responses, strains, and calculated stresses from even large blasts. Ground vibrations of 120-250 mm/s produced worst case strains of about 25 pct of those resulting from pipeline operations and calculated stresses of only about 10-18 pct of the ultimate tensile strength.

  3. Treatment of mine waters discharged from underground uranium mines

    International Nuclear Information System (INIS)

    The National Uranium Company S.A. is dealing with mining and processing of uranium ores. Treatment of mine waters to remove radionuclides such as uranium and radium is a concern in order to reach the permissible values required by local environment authorityies. The decontamination methods and facilities at two underground uranium mines , Suceava and Banat mines respectivelly, are presented. The Suceava mine is active while de Banat mines are closed out since 1998 and ready to be flooded during the 2005-2007 period. It was concluded that removal of uranium and radium from mine waters have a positive environmental impact by decreasing the risk of radiation dose received by critical groups of local population, downside the active or flooded underground mines. Recovered uranium yellow cake and radium rich sludge are transferred for valorization or safe disposal, outside the mine sites. Transfer of uranium loaded resins from the Banat plant to an ore processing plant is foreseen when the same type resin will be used on both sites. Although costly, the mine water treatment at uranium mines is a mandatory task for our mining company in present and also in future

  4. Sources and characteristics of quartz dust in coal mines. Information Circular/1990

    Energy Technology Data Exchange (ETDEWEB)

    Organiscak, J.A.; Page, S.J.; Jankowski, R.A.

    1990-01-01

    Quartz dust is one of the most significant on going health concerns in coal mining today. Since the early 1980's the U.S. Bureau of Mines has conducted numerous studies in underground and surface coal mines to identify the sources of quartz dust and its fundamental characteristics. The report presents data and conclusions obtained from these studies. The two most significant quartz dust sources were found to be the continuous miner excavating rock and the highwall drill operating in a rock overburden. The percentage of quartz was found to be higher in the smaller size fractions of dust when significant amounts of rock were mined by the continuous miner. Another factor theorized to affect quartz dust generation and size characteristics is the morphology of the quartz-bearing rock. Several laboratory studies were conducted to investigate capture efficiency of water spray technology and flooded-bed scrubbers with respect to the particle size of the dust. Water sprays and flooded-bed scrubbers were both found to be less efficient on smaller dust particles, and the scrubber was particularly less efficient on quartz dust. These results indicate that quartz control technology should be directed at controlling smaller sized dust particles.

    Full Text Available Opinion mining is an interesting area of research because of its applications in various fields. Collecting opinions of people about products and about social and political events and problems through the Web is becoming increasingly popular every day. The opinions of users are helpful for the public and for stakeholders when making certain decisions. Opinion mining is a way to retrieve information through search engines, Web blogs and social networks. Because of the huge number of reviews in the form of unstructured text, it is impossible to summarize the information manually. Accordingly, efficient computational methods are needed for mining and summarizing the reviews from corpuses and Web documents. This study presents a systematic literature survey regarding the computational techniques, models and algorithms for mining opinion components from unstructured reviews.

  9. Economic impact of world mining

    International Nuclear Information System (INIS)

    Mining plays a vital role in the economic development of many countries. The emerging economies are now major players in the production and availability of key commodities such as copper (70%), bauxite (40%), iron ore and precious metals. Mining also has a positive impact on the economy of many countries. Another impact of mining can be measured in terms of employment opportunities and income generation. Commercial scale mining provides employment and skills transfer to more than 2 million workers. The multiplier effect increases this benefit by a factor of between 2 and 5. The World Bank Mining Department has carried out an in-depth study on economic and social impact of mining at the community level in Chile, Peru, Bolivia, Papua New Guinea and Mali. This study demonstrates that there are substantial social and economic benefits to the community. The most positive cases are related to the growth of local small- and micro-enterprise activities. However, mining remains controversial, as true sustainable development is not only a matter of financial flows. Mining has also been associated with a number of economic and social problems. As a result there are questions about the sustainability of the economic outcome of mining. The contribution of mining to sustainable development needs to be considered in terms of economic and technical viability, ecological sustainability and social equity. To achieve this, governments, mining companies and local communities must work together to address these issues. (author)

    Haase, S.; Billman, L.; Gelman, R.

    2012-01-01

    The purpose of this analysis is to provide the U.S. Department of the Interior (DOI) and the Bureau of Land Management (BLM) with an overview of renewable energy (RE) generation markets, transmission planning efforts, and the ongoing role of the BLM RE projects in the electricity markets of the 11 states (Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming) that comprise the Western Electricity Coordinating Council (WECC) Region. This analysis focuses on the status of, and projections for, likely development of non-hydroelectric renewable electricity from solar (including photovoltaic [PV] and concentrating solar power [CSP]), wind, biomass and geothermal resources in these states. Absent new policy drivers and without the extension of the DOE loan guarantee program and Treasury's 1603 program, state RPS requirements are likely to remain a primary driver for new RE deployment in the western United States. Assuming no additional policy incentives are implemented, projected RE demand for the WECC states by 2020 is 134,000 GWh. Installed capacity to meet that demand will need to be within the range of 28,000-46,000 MW.

  12. Development of a concrete placement device for support of abandoned mines

    International Nuclear Information System (INIS)

    Burnett Associates, Inc. (BAI), under contract to the US Bureau of Mines, has developed a reliable and cost effective method of remote placement of point support columns in abandoned mines through boreholes to provide local support, especially under surface structures in subsidence prone areas. The development of the system to remotely build a concrete support cylinder in an abandoned mine required the coordination of mechanical system and concrete design. The mechanical system was designed to remote place concrete in a cylindrical shape. The concrete was designed to meet the requirements of low slump with high enough strength to resist the forces applied by the ground above mine. The support cylinder is fabricated through an 8-inch borehole by pumping concrete through a second 4-in pipe inside the borehole. The 4-in pipe has a flexible trunk on the lower end that is bent from the surface when it is inside the mine void. When pumping starts, the 4-in pipe is rotated and a spiral of concrete is placed on the mine floor. Operation continues until the concrete seals at the roof. A normal weight concrete as recommended by ACI 211 having a maximum slump of 1--2 in, a maximum coarse aggregate size of 1/2 in, and a minimum compressive strength of 5,000 psi was used. Cylinders have been fabricated to roof heights of 6 ft. There does not appear to be a technical height limitation. The concrete cylinder can support up to 40 x 106 lbs when fully cured and filled with gravel, depending on cylinder diameter

  17. The U.S. Forest Service abandoned mine land inventory in Colorado: Background, progress, and preliminary findings

    International Nuclear Information System (INIS)

    The U.S. Forest Service (USFS) and the Colorado Geological Survey (CGS) are continuing a cooperative agreement to identify sites of environmental degradation associated with abandoned and inactive mines on Colorado's USFS administered lands. The USFS Abandoned Mine Land Inventory Project is a open-quotes discoveryclose quotes process and is a precursor to the Environmental Protection Agency's open-quotes Preliminary Assessmentclose quotes process. Identification of environmentally degraded sites may lead to a formal Preliminary Assessment. The inventory process begins in the office and involves reviewing existing mining and geologic literature, previous mine inventory work, current and historical maps, water quality information, and aerial photographs. During field investigation, each mine feature is given a unique identification number. Field geologists collect data on the physical and geographic characteristics of the mine features along with information on any water emanating from or interacting with the mine features. This information is used to assign a qualitative environmental degradation rating to the individual mine feature. Guidelines for the rating system are given to field personnel to facilitate consistency within the data set. All data collected are entered into a computer database. From a computer perspective, both location and attribute data are being collected. Therefore, the data are well suited for integration into a geographic information system (GIS) creating a geo-referenced data set. The USFS Abandoned Mine Land Inventory Project began in 1991 and is ongoing. To date, field inventories of the Arapaho, Roosevelt, Pike, and Rio Grande National Forests have been completed. Work in the San Isabel, San Juan, White River, Gunnison, Uncompahgre, and Grand Mesa National Forests is in progress. Through the 1994 field season approximately 9,667 mine features (openings, dumps, tailings, highwalls, etc.) have been inventoried

  16. Economics of mining law

    Science.gov (United States)

    Long, K.R.

    1995-01-01

    Modern mining law, by facilitating socially and environmentally acceptable exploration, development, and production of mineral materials, helps secure the benefits of mineral production while minimizing environmental harm and accounting for increasing land-use competition. Mining investments are sunk costs, irreversibly tied to a particular mineral site, and require many years to recoup. Providing security of tenure is the most critical element of a practical mining law. Governments owning mineral rights have a conflict of interest between their roles as a profit-maximizing landowner and as a guardian of public welfare. As a monopoly supplier, governments have considerable power to manipulate mineral-rights markets. To avoid monopoly rent-seeking by governments, a competitive market for government-owned mineral rights must be created by artifice. What mining firms will pay for mineral rights depends on expected exploration success and extraction costs. Landowners and mining firms will negotlate respective shares of anticipated differential rents, usually allowing for some form of risk sharing. Private landowners do not normally account for external benefits or costs of minerals use. Government ownership of mineral rights allows for direct accounting of social prices for mineral-bearing lands and external costs. An equitable and efficient method is to charge an appropriate reservation price for surface land use, net of the value of land after reclamation, and to recover all or part of differential rents through a flat income or resource-rent tax. The traditional royalty on gross value of production, essentially a regressive income tax, cannot recover as much rent as a flat income tax, causes arbitrary mineral-reserve sterilization, and creates a bias toward development on the extensive margin where marginal environmental costs are higher. Mitigating environmental costs and resolving land-use conflicts require local evaluation and planning. National oversight ensures

    Md-Nor, Zainalabidin; Kecojevic, Vladislav; Komljenovic, Dragan; Groves, William

    2008-06-01

    The paper presents the results of research aimed at developing a risk assessment process that can be used to more thoroughly characterise risks associated with loader- and dozer-related fatal incidents in US mining. The assessment is based on historical data obtained from the US Mine Safety and Health Administration investigation reports, which includes 77 fatal incidents that occurred from 1995 to 2006. The Preliminary Hazard Assessment method is used in identifying and quantifying risks. Risk levels are then developed using a pre-established risk matrix that ranks them according to probability and severity. The resulting assigned risk value can then be used to prioritise risk control strategies. A total of 10 hazards were identified for loaders. The hazards 'failure to follow adequate maintenance procedure' and 'failure of mechanical/electrical/hydraulic components' were the most severe and frequent hazards and they fell into the category of 'high' risk. The same number of hazards was identified for dozers. The hazard 'failure to identify adverse site/geological conditions' was the most severe and frequent hazard and it fell into the category of 'high' risk. PMID:18642163

The affiliated Service Networks (IVS, ILRS, IGS, IDS, and now the IGFS and the PSMSL) continue to grow geographically and to improve core and co-location site performance with newer technologies. Efforts are underway to expand GGOS participation and outreach. Several groups are undertaking initiatives and seeking partnerships to update existing sites and expand the networks in geographic areas void of coverage. New satellites are being launched by the Space Agencies in disciplines relevant to GGOS. Working groups now constitute an integral part of the Bureau, providing key service to GGOS. Their activities include: projecting future network capability and examining trade-off options for station deployment and technology upgrades, developing metadata collection and online availability strategies; improving coordination and information exchange with the missions for better ground-based network response and space-segment adequacy for the realization of GGOS goals; and standardizing site-tie measurement, archiving, and analysis procedures. This poster will present the progress in the Bureau's activities and its efforts to expand the networks and make them more effective in supporting GGOS.

  15. Groundwater restoration of uranium ISL mines in the United States

    International Nuclear Information System (INIS)

    Although the in-situ leach (ISL) mining of uranium in the US started in the 1960's, the real expansion of this form of mining, which is also called solution mining, took place in the early to mid 1970's in Texas. Some of the early test work used an acid lixiviant but it was soon recognized that, because of environmental considerations, the use of alkaline lixiviants would be preferable to the regulatory agencies and the public. In the past, the two types of alkaline based lixiviants used at US ISL mines were ammonia bicarbonate and sodium bicarbonate. A few ISL mines get by with just adding carbon dioxide to the well field solution. Ammonia bicarbonate is no longer being used today in the US because of the difficulties and expense of restoring the water quality to acceptable standards following mining. This paper briefly describes ISL mining principles and then details procedures and techniques used at USA ISL uranium mines to restore water quality in the mined aquifer. The basic elements are fairly constant but there can be considerable variation in type of water treatment equipment, methods of waste water disposal and use of chemical reducing agents. Three case histories are also presented

  2. Groundwater impacts of solution mining

    International Nuclear Information System (INIS)

    In some cases the mining of certain minerals can be achieved without the large-scale excavations involved in open pit or shaft mining. Instead, water is used to liquify the desired mineral so that it can be readily removed without disturbing the host medium or intervening deposits. In Texas this solution mining technique is used in the mining of brines, sodium sulfate, sulfur, and uranium. The advantages stem from the nondisturbing nature of the method that leaves the surface and subsurface physically intact. This is advantageous not only during mining, but also upon its termination when there is a minimum restoration requirement of the terrain. However, in some cases these advantages may be somewhat offset when a considerable chemical restoration of a host aquifer is required. The situation is considerably different with the solution (in situ) mining of uranium since these deposits often occur in usable quality groundwater aquifers. There are twenty-eight permitted sites in Texas. Eight have not yet been mined. This paper discusses the solution mining of uranium in Texas

  5. Laboratory determination of signature criteria for locating and monitoring abandoned mine fires, 1991. Rept. of Investigations/1991

    International Nuclear Information System (INIS)

    The U.S. Bureau of Mines mine fire diagnostic methodology to locate and monitor fires in abandoned mines and waste banks is based on the controlled sampling of the mine atmosphere to determine changes in the concentration of hydrocarbons desorbed from heated coal. To provide background data for the methodology, a laboratory study was conducted in which samples of coal and coal waste were heated under controlled conditions. Gas samples from the combustion furnace were analyzed for standard gases CO2 and CO and for the C1 to C5 hydrocarbons. In all tests, the concentration of desorbed hydrocarbons increased during heating and decreased during cooling. A dimensionless hydrocarbon ratio, R1, was developed as the signature for heated coal. For bituminous coals, the value of R1 increases during heating of coal samples and decreases during cooling of the same samples. Generally, R1 values of 100 or more indicate coal sample temperatures of at least 100 C. The emission of higher molecular weight hydrocarbons from anthracite samples was very low, resulting in relatively low R1 values at all temperatures. Data from field projects confirmed these results

    1996-12-31

    This paper presents research, conducted by the Bureau of Mines, on modifying the influence function method to predict subsidence. According to theory, this technique must incorporate an intensity function to represent the relative significance of the causes of subsidence. This paper shows that the inclusion of a reasonable intensity function increases the accuracy of the technique, then presents the required functions for case studies of longwall coal mining subsidence in Illinois, USA, potash mining subsidence in new Mexico, USA, and subsidence produced by ground water withdrawal in California, USA. Finally, the paper discusses a method to predict the resultant strain from a simply measured site constant and ground curvatures calculated by the technique. (orig.)

    2015-12-01

    The tin mining activities in the suburbs of Jos, Plateau State, Nigeria, have resulted in technical enhancement of the natural background radiation as well as higher activity concentrations of primordial radionuclides in the topsoil of mining sites and their environs. Several studies have considered the radiological human health risks of the mining activity; however, to our knowledge no documented study has investigated the radiological impacts on biota. Hence, an attempt is made to assess potential hazards using published data from the literature and the ERICA Tool. This paper considers the effects of mining and milling on terrestrial organisms like shrubs, large mammals, small burrowing mammals, birds (duck), arthropods (earth worm), grasses, and herbs. The dose rates and risk quotients to these organisms are computed using conservative values for activity concentrations of natural radionuclides reported in Bitsichi and Bukuru mining areas. The results suggest that grasses, herbs, lichens, bryophytes and shrubs receive total dose rates that are of potential concern. The effects of dose rates to specific indicator species of interest are highlighted and discussed. We conclude that further investigation and proper regulations should be set in place in order to reduce the risk posed by the tin mining activity on biota. This paper also presents a brief overview of the impact of mineral mining on biota based on documented literature for other countries. PMID:26093469

  15. U.S. Geological Survey Field Leach Test for Assessing Water Reactivity and Leaching Potential of Mine Wastes, Soils, and Other Geologic and Environmental Materials

    Science.gov (United States)

    Hageman, Philip L.

    2007-01-01

    The U. S. Geological Survey (USGS) has developed a fast (5-minute), effective, simple, and cost-effective leach test that can be used to simulate the reactions that occur when materials are leached by water. The USGS Field Leach Test has been used to predict, assess, and characterize the geochemical interactions between water and a broad variety of geologic and environmental matrices. Examples of some of the samples leached include metal mine wastes, various types of dusts, biosolids (processed sewage sludge), flood and wetland sediments, volcanic ash, forest-fire burned soils, and many other diverse matrices. The Field Leach Test has been an integral part of these investigations and has demonstrated its value as a geochemical characterization tool. It has enabled investigators to identify which constituents are water reactive, soluble, mobilized, and made bioaccessible because of leaching by water, and to understand potential impacts of these interactions on the surrounding environment.

    1982-05-01

    This article outlines general advantages of surface mining technology and aspects of selecting the most suitable mining technology in surface mine projection. Heavy surface mining equipment of the TAKRAF engineering plants is recommended for efficient excavation and overburden removal up to 230,000 m/sup 3/d capacity with the largest excavator type and 440,000 m/sup 3/d capacity with the largest overburden conveyor bridge. Two major variants of surface mine technology are outlined: design of surface mines with continuous working equipment (bucket wheel or bucket chain excavators requiring up to 200 N/cm digging force for minerals and overburden and haulage by belt conveyors) or discontinuously working equipment (dragline excavators, truck transportation, etc.). The second major variant concerns overburden removal to the spoil bank, either by haulage in a semicircle around the pit or by a shortcut across the pit from the excavation to the spoil bank side (direct spoil removal method). TAKRAF equipment for surface mining operations is described with various specifications and details on its performance. (In German)

  2. Uranium mining and milling work force characteristics in the western US

    International Nuclear Information System (INIS)

    This report presents the results of a survey of the socioeconomic characteristics associated with 11 uranium mine and mill operations in 5 Western States. Comparisons are made with the socioeconomic characteristics of construction and operating crews for coal mines and utility plants in eight Western States. Worker productivity also is compared with that in similar types of coal and uranium mining operations. We found that there existed no significant differences between the socioeconomic characteristics of construction and operating crews and the secondary employment impacts associated with uranium mines and mills when compared with those associated with coal mines and utility plants requiring similar skills at comparable locations. In addition, our survey includes a comparison of several characteristics associated with the households of basic and nonbasic work forces and concludes that significant changes have occurred in the last 5 yr. Accordingly, we recommend additional monitoring and updating of data used in several economic forecasting models to avoid unwarranted delays in achieving national energy goals

  12. Recognition of the dosimetric calibration capacities of Cuba by the International Bureau of Weights and Measures

    International Nuclear Information System (INIS)

    The declared mission of the International Bureau of Weights and Measures are the world uniformity of the measurement, however until some years ago a formal mechanism didn't exist for its complete implementation. With this end arose the Mutual Recognition Agreement whose specific objective is to establish the grade of equivalence of the national standards, the one of mutually recognizing the calibration and measurement certificates and the one of providing to the governments of a sure technical tool in its commercial negotiations and regulatory matters at international level. Cuba like an associated country to the Meter Convention, signed the agreement and it intended to demonstrate the international equivalence of its standards. The best measurement and calibration capacities of the country in the dosimetric magnitudes are in the Secondary Laboratory of Dosimetric Calibration of the Protection and Hygiene of Radiations Center. This capacities were included in the Regional Metrological Organization COOMET in the year 2003. In June of the 2005 the metrological capacities have been approved and published in the databases of the International Bureau of Weights and Measures as demonstration of the high competition of the calibration works that its are carried out in the laboratory. This approval is one of the maximum international recognitions that the patterns of a country can receive and its are the result of 10 years of work of the laboratory like part of the international net OIEA/OMS, which has given it the possibility to gauge the patterns and of adopting internationally validated calibration methodologies. On the other hand, it has been decisive the participation of the laboratory in multiple international comparisons of their patterns, as well as the implementation of a system of administration of the quality credited by the competent national organ. The article reviews the technical work of the laboratory during several years that it gave as result this

  13. Development of mining at Jaduguda

    International Nuclear Information System (INIS)

    The paper deals with the development of mining and other infrastructural activities of the underground mine at Jaduguda. In the beginning open and shrinkage methods were used but gradually changed to Cut and Fill method, the fill being the deslimed mill tailings. This method gives much better recovery and provides adequate support to the worked out areas. The main entry to the mine is via a vertical shaft, 640 meters deep. The winders for ore hoisting and the services are installed on top of the concrete tower constructed above the shaft. As the winders are the life line of the mine, a high standard of maintenance is maintained. As the mine is located at the foot hill, there is a fair amount of seepage water. The seepage and the water from the fill is pumped to surface in stages. The sumps at various levels are designed to provide storage capacity. From time to time, the technological improvements in the various mining operations are brought about. The drilling of uppers by stope wagons, use of tyre mounted loaders in the stopes, use of ammonium nitrate for blasting purposes, the use of full column grout bolts are some examples. Studies are also conducted in the ground control in underground. Constant efforts are made to improve the support system. The training courses are regularly arranged for workers to update their skills. As the job in underground is hazardous, the workers are trained in the correct and safe methods of doing the various jobs. (author). 10 figs

    2004-09-01

    The refractory research group at the Albany Research Center (ARC) has a long history of conducting materials research within the U.S. Bureau of Mines, and more recently, within the U.S. Dept. of Energy. When under the U.S. Bureau of Mines, research was driven by national needs to develop substitute materials and to conserve raw materials. This mission was accomplished by improving refractory material properties and/or by recycling refractories using critical and strategic materials. Currently, as a U.S. Dept of Energy Fossil Energy field site, research is driven primarily by the need to assist DOE in meeting its vision to develop economically and environmentally viable technologies for the production of electricity from fossil fuels. Research at ARC impacts this vision by: • Providing information on the performance characteristics of materials being specified for the current generation of power systems; • Developing cost-effective, high performance materials for inclusion in the next generation of fossil power systems; and • Solving environmental emission and waste problems related to fossil energy systems. A brief history of past refractory research within the U.S. Bureau of Mines, the current refractory research at ARC, and the equipment and capabilities used to conduct refractory research at ARC will be discussed.

Looking for items to be able to propose alternatives in order to consolidate a new mining process socially and environmentally sustainable, claiming the value of the ancestral practices and forms of the redistributive production. To this end, it is necessary to start with the discussion of the concepts of formalization and legality, so that we can generate a theoretical framework that will allow us to explore such delicate matter, we will continue to make the framework socio-political, in which it is based that strategy. Then there is a brief context of thereformulation of legal mining, focusing our attention particularly standards which involves or has effects on artisanal mining and/or small-scale mining. There we will find ourselves with a debate on the typology of the mining and the current difficulties to define schemasof legalization or formalization of small-scale mining in Colombia. To conclude with a proposal to formalize as a mechanism of transition to an administrative system - legislativethat will connect more effectively with the realities and skills of the ethnic communities that practice small-scale mining.

  17. La hydrogeology en la traditional mining of hydrocarbons, mining new

    International Nuclear Information System (INIS)

    Is presented from the point of view of Geosciences, an approach torelations between hydrogeology and mining activities, including those of traditional non - metal deposits of ores and rocks application (underground or open pit), the so-called ''modern mining'' (pickles) and hydrocarbons. Within the traditional mining, hydrogeology participates decisively several aspects, both those related to the feasibility of the projects, water supply for the stage of exploration and exploitation, mineraloductos ácueosand mine operations, such as environmental protection of water resources. In the ''modern mining'' groundwater acquires true character mena when it comes to the use of natural brines, and subject when they are generated by injecting water into an aquifer medium. In the case of hydrocarbons, the spectrum is broader participation at the stage of exploration and exploitation, where the hydrogeology is critical to providing water to camps and processes as well as operations secondary recovery, consumers strongly. From the perspective of environmental protection, are the main protagonists of groundwater the impacts of production, but also the phases are transportation, processing and marketing. They are used in the presentation of case examples of Argentina and Chile, some reflections on the need for an appropriate regulatory framework, especially addressed to Uruguay, and information to protect the population activity production of an unfair detriment, when mining is done responsibly

    Forests in the Changbai Mountains are important timber sources for economic development of the society and provide ecological services in northeast China. In order to strengthen forest resource management, this paper analyzed management-induced changes in forest structure, tree species composition and forest landscape pattern from 1987 to 2000 for Baihe Forestry Bureau in Jilin Province based on digitized forest parcel maps and forest survey data. The results suggested that the area of Mature, High-Stocking, and Close-Canopy Forests decreased by 31.4%, 55.9% and 10.7% respectively; volume of Mixed Forest, the native forest vegetation type, decreased by 17.8%;the number of patches increased tremendously but the mean patch density decreased sharply for Mature, High-Stocking, Close-Canopy, and Mixed Forests. All the changes in forest structure, species composition, and landscape pattern indicated severe degradations going on with the forests in Baihe Forestry Bureau. Because of the effect of degradation to forest services, restoring forest resources and protecting biodiversity has become urgently important. The strategies of sustainable forest management need to be worked out and implemented.

    1993-01-01

    The U.S. Bureau of Land Management recognized a need for baseline hydrologic data and an understanding of the hydrologic system in the L.C. Holding coal-lease tract in order to determine the potential effects of mining on the water resources of the area. The potential impacts of mining on the hydrology of the area are of concern because Zion National Park is less than 3 miles from the westernmost part of the lease tract. Much of the water that passes through the Park either originates in the lease tract or traverses it. Runoff from melting snowpacks and summer thundershowers contributes most of the flow to perennial streams in the area. Base flow is sustained by spring discharge and diffuse seepage. Regional groundwater movement is southward. Most of the geologic formations in the study area contain aquifers. The water table of the regional aquifer is about 870 ft deep in the Navajo Sandstone. Groundwater issuing from the Navajo Sandstone on the east side of Zion Canyon has specific conductance values several times larger than groundwater from the west side, indicating recharge to the Navajo from the overlying strata, which contain water of larger specific conductance. Potential effects of mining in the area include: (1) increased dissolved-solids concen- trations and decreased pH values in both surface and groundwater; (2) dewatering of aquifers, causing a decrease or cessation of flow to some springs; and (3) land subsidence and associated subsidence fractures.

  2. Environmental heritage of oil shale mining

    International Nuclear Information System (INIS)

    Oil shale mining like every kind of exploitation of mineral resources imparts a variety of impacts on the environment. One group of factors has a temporary impact during the mining activities only, another group of factors leaves its footprints in nature for a long time. Geological conditions, mining methods underground or surface mining, roof control methods and methods of reclamation determine the variety of landforms and their parameters in post mining landscape. Long-time ecological observations and changing economical conditions can influence the current attitudes and criteria of assessments of the environmental impact caused by mining. (author)

    Tynanthus panurensis (Bureau) Sanwith (Bignoniaceae) is a liana vine used in traditional Amazonian medicine as a tonic and energizer as well as a treatment for rheumatism. These traditional indications prompted this study of the antioxidant and anti-inflammatory activities of T. panurensis bark extract (ETP). Phytochemical analysis of ETP showed the presence of saponins and a high concentration of phenols and flavonoids. A battery of in vitro tests revealed that the extract has free radical-scavenging antioxidant properties and reduces microsomal lipid peroxidation, uric acid synthesis, and tumor necrosis factor-α production. The anti-inflammatory properties of ETP were further confirmed in vivo in a rat carrageenan edema model, in which the extract exhibited a potent activity. These results support the idea that T. panurensis bark extract could be beneficial for treating inflammation and are in agreement with one of the main traditional uses of this plant. PMID:21488753

  8. Problematic of mining environmental liabilities in Colombia

    International Nuclear Information System (INIS)

    Mining environmental liabilities (PAM from its acronym in Spanish) are areas where there is a need for restoration, mitigation or compensation for environmental damage or unmanaged impact, produced by inactive or abandoned mining that threatens health, quality of life or public or private property. In Colombia the environmental liabilities from mining have not been regulated, but given the age and the prevalence of informality in mining, there is increasing interest in defining, regulating and managing these obligations. In this paper we approach the problem of valuing mining environmental liabilities by examining different management approaches for such liabilities around the world. We also identify key information requirements to manage mining environmental liabilities in Colombia.

    2011-12-01

    The booming commodities markets of the past seven years have created an enormous demand for economic geologists, mining engineers, and extractive metallurgists. The mining sector has largely been recession proof due to demand drivers coming from developing rather than developed nations. The strong demand for new hires as well as mid-career hires has exposed the weakness of the U.S. university supply pipeline for these career fields. A survey of mining and metallurgical engineering faculty and graduate students was conducted in 2010 at the request of the Society for Mining, Metallurgy, and Exploration. The goals of the surveys were to determine the demographics of the U.S. faculty in mining and metallurgical engineering, the expected faculty turn over by 2010 and the potential supply of graduate students as the future professorate. All Mining Engineering and Metallurgical Engineering degrees in the U.S. are accredited by the Accreditation Board for Engineering and Technology (ABET) and the specific courses required are set by the sponsoring professional society, Society for Mining, Metallurgy, and Exploration. There are 13 universities in the U.S. that offer a degree in Mining Engineering accredited as Mining Engineering and 1 university that grants a Mining Engineering degree accredited under general engineering program requirements. Faculty numbers are approximately 87 tenure track positions with a total undergraduate enrollment of slightly over 1,000 in the 2008-2009 academic year. There are approximately 262 graduate students in mining engineering in the U.S. including 87 Ph.D. students. Mining Engineering department heads have identified 14 positions open in 2010 and 18 positions expected to be open in the next 5 years and an additional 21 positions open by 2020. The current survey predicts a 56% turn over in mining faculty ranks over the next 10 years but a retirement of 100% of senior faculty over 10 years. 63% of graduate students say they are interested in

    1995-12-31

    The U.S. Bureau of Mines (USBM) and Diesel Controls Limited evaluated a new diesel emission control system on an underground mine vehicle. The system was a catalyzed ceramic wall-flow diesel particulate filter (CDPF) combined with an catalytic converter, or diesel oxidation catalyst (DOC). This paper describes the design and installation of the system on a load-haul-dump (LHD). The results of screening tests conducted by the USBM are also given. The screening tests were conducted to determine if the device`s particulate collection efficiency, regeneration temperature, and effect on gaseous hydrocarbon (HC) and carbon monoxide (CO) emissions changed over the period it was being used. The system was removed from the LHD and evaluated in the laboratory after operating for 308 and 1200 hours. After 308 hours of operation, laboratory testing revealed its particulate collection efficiency varied from 41.0 to 93.5 percent, depending on engine operating conditions. Its regeneration temperature was about 415{degrees}C. It reduced HC emissions by up to 97.6 percent, and CO by up to 95.0 percent. When tested in the laboratory after operating for 1200 hours on the vehicle, no significant change in performance was observed.

  16. Hydrologic variations due to longwall mining

    International Nuclear Information System (INIS)

    This paper reports that the impact of longwall mining on the local hydrological regime has become an important environmental focal point. Unfortunately, only a few studies have addressed the timing and range of well fluid level fluctuations and the associated ground movement. Furthermore, even fewer studies have determined the influence of longwall mining on water quality. The U.S. Bureau of Mines is providing insight into this environmental concern through a program of field case studies. One such study was conducted in Cambria County, PA where five observation water wells were drilled above two adjacent longwall panels. In this study, three wells were completed as nested piezometers and the remaining two served as producing wells. The piezometers were positioned along a line oriented subparallel to the longwall face and were located at the centerline of each panel and over the intervening chain pillars. The piezometers were designed to monitor fluid level fluctuations in both shallow and deep water-bearing zones. Slug tests were conducted before and after mining to characterize changes in hydraulic conductivity of the respective water-bearing zones. Pressure transducers and data loggers were installed to provide continuous fluid level fluctuation data as mining developed through the study area. The producing wells were drilled to provide water quality information. One well was located directly above the centerline of a panel and the other was positioned over the panel's set-up rooms

On the basis of the characteristics of the mine environmental problems, they are classified into (1) three wastes problem, (2) ground distortion, (3) contradiction among mine drainage, water supply, ecological environment,(4) desertification, and (5) soil erosion. The evaluation is the basis of mine environmental problem classification and investigation, mine environmental rehabilitation, and the information system constructed can be used for subsequent research of evaluation techniques. A synthetic assessment of the 5 kinds of mine environmental problems can be divided into single-factor or multi-factor synthetic assessments; while by the viewpoint of time, the mine environmental assessment can be classified as the historical assessment, the current status assessment and the forecasting assessment.

  5. Code of Practice for the safe transport of radioactive substances - Nuclear Safety Bureau experience

    Full text: For Australia, the International Atomic Energy Agency (IAEA) Regulations for the Safe Transport of Radioactive Material, 1985 Edition, are implemented by the Code of Practice for the Safe Transport of Radioactive Substances 1990. The supervision of the revision of all documents in the IAEA's radioactive materials transport safety standards, and supporting documents, program is carried out by the Transport Safety Standards Advisory Committee (TRANSSAC). Australia has a seat on TRANSSAC and the Australian delegate is provided by the Nuclear Safety Bureau (NSB). The revision of the IAEA Transport Regulations is essentially complete and the new edition is due for publication before the end of 1996. This revision incorporates a system of radiological protection that is consistent with the revised IAEA Basic Safety Standards as well as publication ICRP 60 of the International Commission on Radiological Protection. Changes from the 1985 Edition include a new requirement for Radiation Protection Programmes. The exemption level of 70 Bq/g in the current Transport Regulations has no scientific basis and may not be satisfactory for all radionuclides. An advanced draft of the 1996 Edition of the Regulations included wording for the exemption of certain naturally occurring materials which posed difficulties for the mineral sands, and other, industries. Australian attendance at the TRANSSAC meeting was instrumental in revising the wording to provide a consistent and practical approach to the exemption of naturally occurring materials from the Regulations. The transport by road of some of the radioactive waste stored at the Australian Defence Industries site at St Marys, NSW, to Commonwealth land at Woomera Rangehead, SA, took place in 1995. The Federal Minister designated the Australian Radiation Laboratory (ARL) as the Competent Authority for the shipment.

  7. Mine-induced sinkholes over the U.S. Strategic Petroleum Reserve (SPR) storge facility

    Energy Technology Data Exchange (ETDEWEB)

    Neal, J.T.; Bauer, S.J.; Ehgartner, B.L.

    1995-12-31

    The initial sinkhole at the Weeks Island SPR site that was first observed in May 1992 gradually enlarged and deepened, concurrent with the increasing dissolution of salt over the mined oil storage area below. Beginning in 1994 and continuing to the present, the injection of saturated brine directly into the sinkhole throat some 76 in (250 ft) beneath the surface essentially arrested further dissolution, buying time to make adequate preparation for the safe and orderly transfer of crude oil to other storage facilities. A second and much smaller sinkhole was first noticed in early 1995 on an opposite edge of the SPR mine, but with a very similar geological and mine mechanics setting. Both sinkholes occur where the edges of upper-152 in (-500 ft) and lower-213 m (-700 ft) storage levels are nearly vertically aligned. Such coincidence maximizes the tensional stress development leading to fracturing in the salt. Such cracking takes years to develop, perhaps 20 or more. The cracks then become flowpaths for brine incursion, wherein after time it is released into mined openings. Undersaturated ground water gradually enlarges the cracks in salt, leading to further dissolution and eventual collapse of the overlying sand to form sinkholes. Other geologic conditions may have been secondary factors in controlling both mining extent and sinkhole location. An en echelon alignment of sinkholes over other mine edges has been observed. Thus most likely areas of future occurrence at Weeks Island are adjacent to the existing sinkholes; surface inspections are now concentrated at those locations. Although neither timing nor location is predictable with precision, the study of numerous sinkholes elsewhere shows that progression is inevitable, provided that relevant conditions and enough time exists for development. These principles should provide mine designers and operators the knowledge to minimize the occurrence of sinkholes, and to plan for their progression when they occur.

    Science.gov (United States)

    Newman, R D; Mercer, M A

    2000-01-01

    This article reviews the literature on the environmental effects of anti-personnel land mines globally. Land mines represent an immediate environmental health problem. Between 60 and 70 million land mines are currently in place in over 70 countries. Designed to kill or main humans, including civilians, they injure an estimated 1, 200 persons and kill another 800 every week. Land-mine injuries tend to be serious; an estimated 300,000 persons worldwide have been disabled by them. The problem, politically very controversial, can be resolved only by preventing the further placement of mines, by demining of areas already mined, and by coping with the personal and environmental devastation that they have already caused. Environmental health personnel should be involved in promoting awareness of the problem, in improving services for land-mine victims, and in promoting political efforts to ban further use of land mines.

    This report summarizes results of a visit by the report authors to Marinduque Island, Philippines, in May 2000. The purpose of the visit was to conduct a preliminary examination of environmental problems created by a 1996 tailings spill from the Marcopper open-pit copper mine. The mine was operated from 1969-1996 by Macropper Mining Corperation, under 39.9% ownership, and design and management control of Placer Dome, Inc. Our trip expenses to and from the Philippines were funded by the USGS. In-country expenses were paid by the offices of Congressman Reyes and the Governor of Marinduque, Carmencita O. Reyes. This report includes observations we made based on our relatively short visit to the island, and observations based upon a preliminary review of the literature available on the islanda??s mining-environmental issues. In addition, we have included preliminary interpretations and analytical results of some water, sediment, and mine waste samples collected during our trip. We also highlight the environmental and human health issues we fell are in need of further study and consideration for mitigation or remediation. This report is preliminary and is not intended to be a comprehensive or final review of the islanda??s mining-environmental issues; many areas of further study are clearly neededa?|

  2. Capture and Use of Coal Mine Ventilation Air Methane

    Energy Technology Data Exchange (ETDEWEB)

    2008-10-31

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

  3. Evolution of Acid Mine Drainage Formation in Sulphidic Mine Tailings

    2014-07-01

    Full Text Available Sulphidic mine tailings are among the largest mining wastes on Earth and are prone to produce acid mine drainage (AMD. The formation of AMD is a sequence of complex biogeochemical and mineral dissolution processes. It can be classified in three main steps occurring from the operational phase of a tailings impoundment until the final appearance of AMD after operations ceased: (1 During the operational phase of a tailings impoundment the pH-Eh regime is normally alkaline to neutral and reducing (water-saturated. Associated environmental problems include the presence of high sulphate concentrations due to dissolution of gypsum-anhydrite, and/or effluents enriched in elements such as Mo and As, which desorbed from primary ferric hydroxides during the alkaline flotation process. (2 Once mining-related operations of the tailings impoundment has ceased, sulphide oxidation starts, resulting in the formation of an acidic oxidation zone and a ferrous iron-rich plume below the oxidation front, that re-oxidises once it surfaces, producing the first visible sign of AMD, i.e., the precipitation of ferrihydrite and concomitant acidification. (3 Consumption of the (reactive neutralization potential of the gangue minerals and subsequent outflow of acidic, heavy metal-rich leachates from the tailings is the final step in the evolution of an AMD system. The formation of multi-colour efflorescent salts can be a visible sign of this stage.

  10. A quarter century of coal mining and hydrogeologic research in southeastern Montana

    International Nuclear Information System (INIS)

    Two valuable natural resources coexist in eastern Montana--coal and ground water. Water related issues are the major concerns during coal mine permit decisions. Due to the concerns about mining related impacts, ground water in the vicinity of coal mines has been continuously monitored since 1970. The continuity and duration of the Montana Bureau of Mines and Geology monitoring program under a variety of geologic, mining, and post-mining conditions have provided a fundamental knowledge on impacts to water levels and water quality. Coal beds are among the most dependable and utilized aquifers in eastern Montana, due to their lateral continuity and fracture-related transmissivity. In response to coal strip mining, water levels in coal-bed aquifers have dropped at distances as far as 2 miles away from mines near Colstrip, and as far as 15 miles from mines near Decker. Water levels typically return to pre-mining levels within several years after pits are backfilled. Mining-induced drawdown in stratigraphically deeper aquifers exceed those in mined aquifers in some areas, and relate to inadequately plugged boreholes from older exploration drilling programs. Dissolved-solids concentrations of water in the spoils aquifers have increased by 50 to 200% due to the dissolution of newly available salts of calcium, magnesium, sodium and sulfate. However, in some sites freshening of the water appears to be occurring as initial salt loads are flushed through the systems. Water-quality impacts are expected in off-site and deeper aquifers due to normal ground-water flow, and in deeper aquifers due to poorly plugged exploration drill holes. However, downgradient impacts to water quality are rarely observed. Future ground-water monitoring should document stable water levels and improving water quality as spoils aquifers reach equilibrium with local undisturbed hydrologic systems

  11. Effect of the diurnal cycle and fan shutdowns on radon concentration in an experimental uranium mine. Report of investigations/1982

    International Nuclear Information System (INIS)

    Radon concentrations in shallow uranium mines such as the Bureau of Mines experimental research mine are affected by barometric pressure changes. The radon concentrations show a significant correlation with absolute pressure; but over a period of days, a steady rise or fall in barometric pressure will result in noncorrelation of data. Fan shutdowns also affect radon concentrations, and an equation was derived to determine the time required for the radon concentration to return to normal after a fan shutdown, whether the ventilation is blowing or exhausting

  14. Reclamation of uranium mining and milling disturbances

    International Nuclear Information System (INIS)

    Since 1945 the history of uranium mining and milling in the US has been a story of wide fluctuations in market prices and in mining and milling capacity. The late 1960's and the 1970's saw a sizeable reduction in the production of yellowcake because of an earlier over-supply, a leveling off of the military demand, and a failure of the nuclear electric power industry to create the anticipated commercial demand. The decline in the domestic production of yellowcake has continued through the early 1980's to the present. Today, there are five operating uranium mills in the US: one in Wyoming, two in Utah, one in New Mexico, and one in Texas. Of these five mills, three are operating on a reduced schedule, as little as three days a month. A significant portion of the current US production of uranium goes overseas to fulfill Japanese, French, and other European contracts. There is still a sizeable reclamation job to be accomplished on old uranium wastes, both tailings impoundments and overburden embankments. Before the Uranium Mill Tailings Control Act of 1978 (PL 95-604), reclamation was frequently omitted altogether, or else done in a haphazard fashion. We do not know the total area of unreclaimed, radioactive, uranium overburden wastes in the western US, but the area is large, probably several thousand hectares. Fortunately, these overburden wastes are almost entirely located in remote areas. Mill tailings are more difficult to reclaim than overburden, and tailings represent a more serious health hazards. There are approximately 25 million metric tons of unreclaimed uranium mill tailings, with variable health hazards, located in the US

  16. Mapping of the Frazee Mine, the Western Maryland Coal Combustion By-Products/Acid Mine Drainage Initiative, Part 2 of 3

    International Nuclear Information System (INIS)

    Maryland coal production over the years before 1977 reveals that Maryland coal basins have void space from mining a quarter billion tons of coal. The exposure of sulfur-bearing minerals in these mine voids to oxygen and water generates AMD, which is toxic to aquatic flora and fauna. It is estimated that about 450 miles of waterways in western Maryland are impacted by AMD. The majority of these waterways ultimately drain to the east, and affect the overall water quality of the Chesapeake Bay. Typically, AMD is treated by dosing discharges with limestone, which only provides a temporary solution as AMD continues to form at its source in underground mines. The Maryland Department of Natural Resources (DNR) Power Plant Research Program (PPRP) and the Maryland Department of the Environment Bureau of Mines (MDE) have undertaken the Western Maryland CCB/AMD Initiative (the Initiative), which is a joint effort with private industry to develop permanent solutions to abate AMD at its source. The Initiative's goal is to demonstrate the beneficial application of alkaline CCBs to abate AMD from underground coal mines. The Initiative is based on the concept that alkaline CCBs generated by clean coal technologies, such as fluidized bed combustion (FBC) and flue gas desulfurization (FGD), can be injected into underground mines to prevent the formation of AMD by sealing mines from exposure to oxygen and water. This goal will be met by performing the following: Determining optimum grout formulations for mine injection; Optimizing engineering techniques for mine reclamation to achieve economic viability; Implementing appropriately-sized demonstration projects, progressing to full-scale applications at Maryland's largest abandoned mines; and Developing industry partnerships for implementation of the Initiative's findings to abate AMD in western Maryland

  20. Reorganization of oil shale mining in Estonia

    International Nuclear Information System (INIS)

    Under the present conditions of limited demand for oil shale, the Estonian oil shale mining industry is in a state of over capacity. This results in an inefficient use of labor. This working atmosphere has resulted in high production costs per tonne of mined oil shale. To improve economic factors, it is necessary to concentrate production into a limited number of mines working at full capacity and to modernize the mining technology at those mines. A development plan for oil shale mining is proposed. It primarily includes modernization of the prospective mines to be kept in operation and reduction of surface mining at the Sirgala and Narva open cast pits. This will result in conservation of oil shale reserves for 8- 10 years of future production. It is recommended that the resumption of mining in these fields be by underground means. The detailed plan does not call for the untimely closing of mines before the exhaustion of their reserves of oil shale. At the same time, a relatively stable level of mining activity (10-13 million tonnes per year) with minimal investments in the oil shale industry is guaranteed until 2025. (author)

    Swati Soni

    2012-04-01

    Full Text Available The stock market domain is a dynamic and unpredictable environment. Traditional techniques, such as fundamental and technical analysis can provide investors with some tools for managing their stocks and predicting their prices. However, these techniques cannot discover all the possible relations between stocks and thus there is a need for a different approach that will provide a deeper kind of analysis. Data mining can be used extensively in the financial markets and help in stock-price forecasting. Therefore, we propose in this paper a portfolio management solution with business intelligence characteristics. We know that the temporal high utility itemsets are the itemsets with support larger than a pre-specified threshold in current time window of data stream. Discovery of temporal high utility itemsets is an important process for mining interesting patterns like association rules from data streams. We proposed the novel algorithm for temporal association mining with utility approach. This make us to find the temporal high utility itemset which can generate less candidate itemsets.

    Subahani Shaik

    2015-07-01

    Full Text Available Introduction: The association between pornography and sexual crime is controversial, with various researchers finding positive, no, or negative associations. Recent evidence suggests that there may be a specific association between child pornography, which is easily available on the Internet, and sexual offences against children. Methods: Using methodology similar to an earlier study from India, we obtained official statistics on sexual offences against children, namely rape and procurement of minor girls, for the period 2000-2012 from the National Crime Records Bureau. We analysed the association between the rates of these crimes and Internet access, measured by the number of users per 1,00,000 people. Results: Even after correcting for population growth, we found significant linear associations between Internet availability and the rates of both these offences against children. However, there was no correlation between the growth rate of Internet access and the rate of increase of these crimes. Discussion: While the association between pornography and the rape of adults is still under debate, our results provide indirect evidence of a possible association between Internet availability and sexual crimes against children. Regulation of the Internet to suppress access to child pornography may prevent at least some of these crimes.

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

    International Nuclear Information System (INIS)

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

  8. Monitoring of livestock grazing effects on Bureau of Land Management land

    Veblen, Kari E.; Pyke, David A.; Aldridge, Cameron L.; Casazza, Michael L.; Assal, Timothy J.; Farinha, Melissa A.

    2013-01-01

    Public land management agencies, such as the Bureau of Land Management (BLM), are charged with managing rangelands throughout the western United States for multiple uses, such as livestock grazing and conservation of sensitive species and their habitats. Monitoring of condition and trends of these rangelands, particularly with respect to effects of livestock grazing, provides critical information for effective management of these multiuse landscapes. We therefore investigated the availability of livestock grazing-related quantitative monitoring data and qualitative region-specific Land Health Standards (LHS) data across BLM grazing allotments in the western United States. We then queried university and federal rangeland science experts about how best to prioritize rangeland monitoring activities. We found that the most commonly available monitoring data were permittee-reported livestock numbers and season-of-use data (71% of allotments) followed by repeat photo points (58%), estimates of forage utilization (52%), and, finally, quantitative vegetation measurements (37%). Of the 57% of allotments in which LHS had been evaluated as of 2007, the BLM indicated 15% had failed to meet LHS due to livestock grazing. A full complement of all types of monitoring data, however, existed for only 27% of those 15%. Our data inspections, as well as conversations with rangeland experts, indicated a need for greater emphasis on collection of grazing-related monitoring data, particularly ground cover. Prioritization of where monitoring activities should be focused, along with creation of regional monitoring teams, may help improve monitoring. Overall, increased emphasis on monitoring of BLM rangelands will require commitment at multiple institutional levels.

  9. Legacy of historic mining and water quality in a heavily mined Scottish river catchment

    OpenAIRE

    Haunch, Simon

    2013-01-01

    Mine abandonment and the discharge of contaminated mine water is recognised globally as a major source of surface water and groundwater pollution. Contamination generally arises from the oxidation of sulphide minerals, principally pyrite, by the mining process, and the subsequent chemical reactions can lead to the discharge of mineralised, often acidic, iron, and sulphate rich waters. In many historically mined river catchments, mine water discharge is the main cause of poor wa...

  10. An Empirical Analysis of Australian Gold Mining Firms

    OpenAIRE

    Baur, Dirk G.

    2012-01-01

    This paper studies the exposure of Australian gold-mining firms to changes in the gold price, the stock market and the Australian dollar - US dollar exchange rate. The empirical analysis uses daily, weekly and monthly data of all gold-mining firms in the S&P/ASX All Ordinaries Gold Index for the period from January 1980 to December 2010 and finds that the average gold beta is 0.67 for gold denominated in US dollar and 0.38 for gold denominated in Australian dollars.

  18. Radiological changes due to the restoration of a uranium mine

    International Nuclear Information System (INIS)

    The paper presents a radiological study of a uranium mine in Extremadura, a region in the southwest of Spain. Mining work had already ceased and coincident with the development of this study the mine was being remediated, making it possible to study the influence of the remediation plan on different radiological parameters. The radiological parameters were studied in three groups: aerial samples, soil samples, and water sediment samples. The first two groups were clearly influenced by the remediation work, but the third was not. The results for 222Rn in air and water, 222Rn exhalation, effective 226Ra in soils and sediments, natural uranium and 226Ra in water, and the physico-chemical and meteorological parameters, allowed us to characterize the zone of the mine. Particular variations in certain radiological variables are explained by taking into consideration some of the physico-chemical parameters measured. (author)

  7. Licensing of in situ leach mining for the Crownpoint and Church Rock uranium deposits, New Mexico

    International Nuclear Information System (INIS)

    The licensing activities for the Church Rock and Crownpoint uranium properties was a particularly complex process as the areas to be encompassed by the license were changed during the licensing process, the areas reside within or near conflicting governmental jurisdictions, the efforts attracted the attention of numerous non-governmental organizations, (NGO), and the affected parties include Native Americans. Licensing of in situ leach recovery operations in New Mexico, adjacent to the Navajo Indian Reservation, required significant effort on the part of Uranium Resources, Inc. and the subsidiary, Hydro Resources Inc., since the submittal of the original application in 1988. On January 5, 1998, the U.S. Nuclear Regulatory Commission issued the license to operate following a lengthy Environmental Impact Statement process jointly managed by the U.S. Nuclear Regulatory Commission, the U.S. Bureau of Indian Affairs, and the U.S. Bureau of Land Management. The principal stakeholders include the State of New Mexico, the Navajo Nation and a number of citizen groups. The U.S. Environmental Protection Agency reviewed the Environmental Impact Statement. Since licensing, Hydro Resources Inc. overcame legal challenges to the source material license from groups opposed to uranium development and obtained the necessary water rights from the State of New Mexico on October 19, 1999. On January 19, 2000, the Navajo Nation lifted its 1983 moratorium on uranium mining for uranium in situ leach (ISL) recovery. The Grants Uranium Region is located in northwestern New Mexico and is part of the Colorado Plateau physiographic province. The Jurassic Westwater Canyon Member of the Morrison Formation in the San Juan Basin hosts the uranium. The Crownpoint and Church Rock ore trends are monometallic, regional redox-controlled, roll-front type uranium deposits and occur as stacked roll-fronts. Other uranium deposits in the Grants Uranium Region include humate-type sandstone deposits including

  8. Case studies: Mining, decommissioning and rehabilitation of the Mecsek mining centre in Hungary (1956-2004)

    International Nuclear Information System (INIS)

    The Mecsek Mine, an underground facility, was the only uranium producer in Hungary. It was operated as the state owned Mecsek Ore Mining Company. The mining complex began operation in 1956 and was producing ore from a depth of 600 to 800 m in 1997 when it was permanently shutdown. The uranium ore bodies were 0 to 200 m deep in the southern part of the mountain ridge and up to 1 200 m deep in the northern area. From 1965 to 1989 the company mined 0.1 to 0.3% uranium from Upper Permian (270 Ma) sandstone 'roll-front' ore deposits; additionally, low grade (100-300 ppm) uranium ores were processed for heap leaching. During this period, 7.2 million tonnes of low grade ore were crushed with an average mining recovery of 50-60%. Total uranium production was 21 050 tonnes of uranium, including 525 tonnes of uranium recovered by heap leaching. During the operation, the town of Pecs and the surrounding countryside, including its hillside vineyards and groundwater, were given high priority regarding environmental protection. The most important activities since mine closure in 1997 were the experimental covering of tailings ponds and vertical drainage with waste rock. The decommissioning and remediation efforts gave jobs to hundreds of workers. The programme for total remediation was expected to continue until the end of 2004, but budget constraints resulted in delays and in 2007 final completion of some aspects had yet to be achieved. The Hungarian government assumed full financial responsibility for decommissioning and remediation because the uranium industry was directed and operated by a state owned company. The total cost of the decommissioning and remediation, including radiation protection and human health issues, was about US $105-115 million or US $5 per kilogram of uranium produced. Such a mining venture would probably not be sustainable in today's free enterprise economy. However, at the time of its production, it served the purpose of developing infrastructure for

    Current regulations on land use in the Western United States affect access to surface minable coal resources. This U.S. Geological Survey study analyzes the long-term effects of Federal land-use restrictions on the national cost of meeting future coal demands. The analysis covers 45 years. The U.S. Bureau of Land Management has determined the environmental, aesthetic, and economic values of western Federal coal lands and has set aside certain areas from surface coal mining to protect other valued land uses, including agricultural, environmental, and aesthetic uses. Although there are benefits to preserving natural areas and to developing areas for other land uses, these restrictions produce long-term national and regional costs that have not been estimated previously. The Dynamic Coal Allocation Model integrates coal supply (coal resource tonnage and coal quality by mining cost for 60 coal supply regions) with coal demand (in 243 regions) for the entire United States. The model makes it possible to evaluate the regional economic impacts of coal supply restrictions wherever they might occur in the national coal market. The main factors that the economic methodology considers are (1) coal mining costs, (2) coal transportation costs, (3) coal flue gas desulfurization costs, (4) coal demand, (5) regulations to control sulfur dioxide discharges, and (6) specific reductions in coal availability occurring as a result of land-use restrictions. The modeling system combines these economic factors with coal deposit quantity and quality information--which is derived from the U.S. Geological Survey's National Coal Resources Data System and the U.S. Department of Energy's Demonstrated Reserve Base--to determine a balance between supply and demand so that coal is delivered at minimum cost.

  13. Origin of acid mine drainage in Enugu

    International Nuclear Information System (INIS)

    Mine flooding is a serious problem in the Enugu Coal Mines and has led to the abandonment of two of the four mines. About 1800 m3 of water is pumped out daily from the mines into the nearby streams. The source of this enormous volume of water has been established based on the hydrodynamics and hydrology of the area. Two prolific aquifers - an unconfined and a confined system - overlie the mines, but the mine water is derived principally from the unconfined aquifer. The pathway of flow is, provided by the numerous fractures connecting the two aquifers and the mine tunnel. The major hydrochemical activity resulting in pollution of the mine water occurs within the sumps in the floor of the longwalls. These sumps act as oxidation chambers where groundwater from the fractures mixes and subsequently reacts with sulfur-rich solutes released by coal mining. Contrary to general belief, the mine drainage has not seriously degraded the chemistry of receiving streams. The pH and electric conductivity, representing, the dissolved ions, were increased less than 10% of the values in the unaffected region

  15. The assessment of mine rebound and decanting in deeper coal mines

    Energy Technology Data Exchange (ETDEWEB)

    Vermeulen, P.D.; Dennis, I. [Inst. for Groundwater Studies, Bloemfontein (South Africa)

    2010-07-01

    This groundwater and monitoring study of 7 interlinked deep coal collieries in South Africa was conducted to develop analytical and numerical decant models of individual collieries suitable for integration into a single large model. The model will be used to prevent acid mine drainage after mining activities have stopped. The models considered interconnectivity between the mines, the geology of the overburden, the type of mining conducted at each mine, the topography and depth of the mining activities, and the piezometric levels of the mines and involved aquifers. The overburden formations in the studied region consisted of sandstone, shale, interbedded siltstone, mudstone and coal seams. Removal of the coal seams has resulted in the caving of the overlying strata into mined voids. The mining disruptions have resulted in subsidence and recharges of between 5 and 7 percent. The conceptual decant model predicted that piezometric levels of the mine will rise with the storage coefficient value of the mine. The flux from the overlying aquifers will decrease as water levels even out. Any polluted water will need to overcome 4 bar of pressure to to decant. Excess water above the weathered zone in the mines will seep out as normal unpolluted springs at lower points. Results of the numerical modelling study showed that it is unlikely that the collieries will decant, as the piezometric level of the mines will rise with the storage coefficient value of the mine. 5 refs., 4 figs.

  17. Estimated abundance of wild burros surveyed on Bureau of Land Management Lands in 2014

    Science.gov (United States)

    Griffin, Paul C.

    2015-01-01

    The Bureau of Land Management (BLM) requires accurate estimates of the numbers of wild horses (Equus ferus caballus) and burros (Equus asinus) living on the lands it manages. For over ten years, BLM in Arizona has used the simultaneous double-observer method of recording wild burros during aerial surveys and has reported population estimates for those surveys that come from two formulations of a Lincoln-Petersen type of analysis (Graham and Bell, 1989). In this report, I provide those same two types of burro population analysis for 2014 aerial survey data from six herd management areas (HMAs) in Arizona, California, Nevada, and Utah. I also provide burro population estimates based on a different form of simultaneous double-observer analysis, now in widespread use for wild horse surveys that takes into account the potential effects on detection probability of sighting covariates including group size, distance, vegetative cover, and other factors (Huggins, 1989, 1991). The true number of burros present in the six areas surveyed was not known, so population estimates made with these three types of analyses cannot be directly tested for accuracy in this report. I discuss theoretical reasons why the Huggins (1989, 1991) type of analysis should provide less biased estimates of population size than the Lincoln-Petersen analyses and why estimates from all forms of double-observer analyses are likely to be lower than the true number of animals present in the surveyed areas. I note reasons why I suggest using burro observations made at all available distances in analyses, not only those within 200 meters of the flight path. For all analytical methods, small sample sizes of observed groups can be problematic, but that sample size can be increased over time for Huggins (1989, 1991) analyses by pooling observations. I note ways by which burro population estimates could be tested for accuracy when there are radio-collared animals in the population or when there are simultaneous

    The inflow of mine water to mining operations is often caused by random events such as precipitation. Consequently, the mine water inflow regime can be defined as a function of random events applying the theory of random processes. Regression models of the multiple linear correlation type have been used to simulate the inflow of mine water into mining operations, produce short-range predictions and facilitate rapid response inside the mine. The significance of such models lies in the ability to simulate and predict the consequences (mine water inflow), caused by events of a random nature (meteorological parameters: precipitation and air temperature). The presented prognostic models have been calibrated for mine water inflow to the Štavalj Coal Mine in southwestern Serbia. Mathematical dependencies were defined based on daily mine water inflow rates recorded during the period from 2003 to 2011, which can be used to generate short-range (1-7 day) predictions of mean daily mine water inflow rates to the Štavalj Coal Mine. A strong correlation (coefficient of correlation r = 0.93, Sig. = 0.00) was derived for the one-day forecast. The coefficients of correlation for predictions of mean daily mine water inflow rates related to time periods of two, three...seven days gradually declined to 0.63 (7-day mean daily inflow rate).

  19. Optimizing number of mine cars simultaneously awaiting loading at a mine roadway working face

    Energy Technology Data Exchange (ETDEWEB)

    Jaskowski, A.; Jaworski, J.

    1987-01-01

    Evaluates a mathematical model of coal handling and haulage during mine drivage in a coal seam by drilling and blasting using the WWS-2 drilling equipment. Coal is handled by the DBW-1200 side-dumping loader. Mine cars (capacity of 2.0 or 2.78 m/sup 3/) are moved by a MANTOR tractor. The model is based on a haulage system used in a coal mine in Poland. Mathematical modeling shows that mine car number decisively influences coal handling time, loading time and loader performance. The optimum mine car number depends both on car capacity and handling time. Modeling shows that in most cases the number of mine cars used for haulage in mine drivage in Poland is insufficient. Use of mine cars with a capacity of 2.0 m/sup 3/ in many cases would be more economic than use of 2.78 m/sup 3/ mine cars.

  20. Radioactivity in the copper ore mining and dressing industry: a preliminary assessment

    International Nuclear Information System (INIS)

    As part of its assessment of natural radioactivity in the mineral ore mining and dressing industry, the Office of Radiation Programs, US Environmental Protection Agency (EPA), has collected radiological data on the copper industry. This data consists of survey measurements taken from the literature and recent mine surveys conducted by the US Geological Survey, Bureau of Mines, and EPA. Although gamma analyses of the ore bodies, themselves, show approximate background radiation levels, sampling of ore, copper leachate solutions and mine runoff water show elevated levels of uranium and decay products. Radon measurements conducted by the Mining Enforcement and Safety Administration (MESA) in underground copper mines have also been significantly above background levels (maximum average concentration of 0.33 working levels). Notwithstanding the above-background radiation measurements and the immense amount of waste materials produced by the industry annually (627 million metric tons in 1974), the conclusion of the study is that, other than a potential occupational exposure impact, there is no evidence at present that a public health hazard exists due to the presence of radionuclides in the products, by-products, and wastes of the copper industry

    The Mining Industry of the Future was started in June 1998 when the Chairman of the National Mining Association and the Secretary of Energy entered into a Compact to pursue a collaborative technology research partnership. After the Compact signing, the mining industry developed its vision document, The Future Begins with Mining, A Vision of the Mining Industry of the Future, in September 1998. This vision document lists long-term goals for the mining industry. Stemming from this vision document, targeted technology roadmaps were developed that describe pathways of research to achieve the vision goals.

  7. Accuracy of forecast of mine tremors location

    DRZEWIECKI Jan

    2009-01-01

    The Upper Silesian Coal Basin is one of the most active mining areas in the world in respect of seismicity. Underground mining in this area takes place in a special environment with a high degree of risk of unpredictable event occurrence. Especially dangerous are phenomena that occur during the extraction of deposits at great depths in the environment of compact rocks. Deep underground mining violates the balance of these rocks and induces dynamic phenomena at the longwall life (in terms of distance) referred to as mine tremors. The sources of these tremors are located in layers characterised by high strength, especially in thick sandstone strata occurring in the roof of the mined seam. In the paper a discussion is presented about the influence of mining inten-sity (longwall face speed) on the location of mine tremor sources, both in the direction of longwall life (in terms of distance) and towards the surface. The presented material has been prepared basing on the results of tests and measurements carried out at the Central Mining Institute.

    Kennedy, Ben W.; Langley, Dustin E.

    2007-01-01

    Executive Summary The U.S. Geological Survey, in cooperation with the Bureau of Land Management, completed an assessment of hydrology, water quality, and trace-element concentrations in streambed sediment of the upper Birch Creek watershed near Central, Alaska. The assessment covered one site on upper Birch Creek and paired sites, upstream and downstream from mined areas, on Frying Pan Creek and Harrison Creek. Stream-discharge and suspended-sediment concentration data collected at other selected mined and unmined sites helped characterize conditions in the upper Birch Creek watershed. The purpose of the project was to provide the Bureau of Land Management with baseline information to evaluate watershed water quality and plan reclamation efforts. Data collection began in September 2001 and ended in September 2005. There were substantial geomorphic disturbances in the stream channel and flood plain along several miles of Harrison Creek. Placer mining has physically altered the natural stream channel morphology and removed streamside vegetation. There has been little or no effort to re-contour waste rock piles. During high-flow events, the abandoned placer-mine areas on Harrison Creek will likely contribute large quantities of sediment downstream unless the mined areas are reclaimed. During 2004 and 2005, no substantial changes in nutrient or major-ion concentrations were detected in water samples collected upstream from mined areas compared with water samples collected downstream from mined areas on Frying Pan Creek and Harrison Creek that could not be attributed to natural variation. This also was true for dissolved oxygen, pH, and specific conductance-a measure of total dissolved solids. Sample sites downstream from mined areas on Harrison Creek and Frying Pan Creek had higher median suspended-sediment concentrations, by a few milligrams per liter, than respective upstream sites. However, it is difficult to attach much importance to the small downstream increase

  13. Current expansion of the Elliot Lake mines

    International Nuclear Information System (INIS)

    The Elliot Lake mines are located in northern Ontario, on the north shore of Lake Huron. Mining operations in this area started in the mid-1950's and were curtailed during the 1960's. Starting in 1973 Rio Algom's Quirke mine and Denison, the only producers remaining in the area, started to make plans to expand. Increasing production to 30,000 tpd (milled) requires the reopening of the Panel and Stanleigh Mines of the Rio Algom group and the Stanrock-CanMet area at Denison. The first phase of the expansion was preceded by extensive public hearings. Mine production increases, improvement to the facilities at the reopened mines, and the effects on community facilities are described in this paper

    Energy Technology Data Exchange (ETDEWEB)

    Guernsey, J L; Brown, L A; Perry, A O

    1978-02-01

    This case study examines the reclamation practices of the Georgia Kaolin's American Industrial Clay Company Division, a kaolin producer centered in Twiggs, Washington, and Wilkinson Counties, Georgia. The State of Georgia accounts for more than one-fourth of the world's kaolin production and about three-fourths of U.S. kaolin output. The mining of kaolin in Georgia illustrates the effects of mining and reclaiming lands disturbed by area surface mining. The disturbed areas are reclaimed under the rules and regulations of the Georgia Surface Mining Act of 1968. The natural conditions influencing the reclamation methodologies and techniques are markedly unique from those of other mining operations. The environmental disturbances and procedures used in reclaiming the kaolin mined lands are reviewed and implications for planners are noted.

  18. Geophysical investigation of Red Devil mine using direct-current resistivity and electromagnetic induction, Red Devil, Alaska, August 2010

    Burton, Bethany L.; Ball, Lyndsay B.

    2011-01-01

    Red Devil Mine, located in southwestern Alaska near the Village of Red Devil, was the state's largest producer of mercury and operated from 1933 to 1971. Throughout the lifespan of the mine, various generations of mills and retort buildings existed on both sides of Red Devil Creek, and the tailings and waste rock were deposited across the site. The mine was located on public Bureau of Land Management property, and the Bureau has begun site remediation by addressing mercury, arsenic, and antimony contamination caused by the minerals associated with the ore deposit (cinnabar, stibnite, realgar, and orpiment). In August 2010, the U.S. Geological Survey completed a geophysical survey at the site using direct-current resistivity and electromagnetic induction surface methods. Eight two-dimensional profiles and one three-dimensional grid of direct-current resistivity data as well as about 5.7 kilometers of electromagnetic induction profile data were acquired across the site. On the basis of the geophysical data and few available soil borings, there is not sufficient electrical or electromagnetic contrast to confidently distinguish between tailings, waste rock, and weathered bedrock. A water table is interpreted along the two-dimensional direct-current resistivity profiles based on correlation with monitoring well water levels and a relatively consistent decrease in resistivity typically at 2-6 meters depth. Three settling ponds used in the last few years of mine operation to capture silt and sand from a flotation ore processing technique possessed conductive values above the interpreted water level but more resistive values below the water level. The cause of the increased resistivity below the water table is unknown, but the increased resistivity may indicate that a secondary mechanism is affecting the resistivity structure under these ponds if the depth of the ponds is expected to extend below the water level. The electromagnetic induction data clearly identified the

  6. Impact of Coal Mining on Environment

    Directory of Open Access Journals (Sweden)

    Sribas Goswami

    2015-03-01

    Full Text Available Coal mining adversely affects the eco-system as a whole. On the unstable earth, the unresting mankind constantly uses a variety of resources for daily lives. Coal is recognized to have been the main source of energy in India for many decades and contributes to nearly 27 % of the world’s commercial energy requirement. Coal is mainly mined using two methods- surface or ‘opencast’ and underground mining. The geological condition determines the method of mining. Coal mining is usually associated with the degradation of natural resources and the destruction of habitat. This causes invasive species to occupy the area, thus posing a threat to biodiversity. Huge quantities of waste material are produced by several mining activities in the coal mining region. If proper care is not taken for waste disposal, mining will degrade the surrounding environment. The method of waste disposal affects land, water and air and in turns the quality of life of the people in the adjacent areas. This paper throws lights on the burning issues of coal mines and its impact on the environment.

  7. Evaluation of natural amelioration of acidic deep mine discharges in Western Pennsylvania

    International Nuclear Information System (INIS)

    Abandoned mine drainage (AMD) has long been the most serious water quality and watershed degradation problem in the Appalachian region of the U.S. and in some other areas of the nation. In several areas of western Pennsylvania, deep mine discharges that were reliably described as highly acidic in the 1960s and 1970s have shown natural amelioration of CO2 acidity. A number of different factors, including mine flooding and overburden chemistry, may cause improvement in mine water quality. The authors are studying the hydrologic and geochemical factors responsible for improvements over time in the quality of water discharges from abandoned deep mines. The project is focused on the study of a set of mine water discharges associated with abandoned, interconnected deep mines in the Uniontown Syncline of Western Pennsylvania. This area was studied extensively under Pennsylvania's Operation Scarlift in the early 1970s, and one year of monthly water quality data are available from 1974-75. The mined-out coal basin of the Uniontown Syncline is unique in that different mining methods were employed in the same coal seam over the basin. The resulting discharges are from flooded, unflooded, and partially flooded abandoned underground coal mines. This paper presents an overview of the hydraulic system in the mine network of the Uniontown Syncline along with a summary of selected data from the 1974-75 and 1998-99 studies. Preliminary interpretations of these data in relation to the Scarlift data are also presented

  11. The Labor-saving Kitchen: Sources for Designs of the Architects’ Small Home Service Bureau

    Directory of Open Access Journals (Sweden)

    Lisa M. Tucker

    2014-12-01

    Full Text Available The history of the kitchen has received much attention from designers and design historians. Since the writings of Catharine Beecher, designers, household engineers, and others have written about the importance of the kitchen as the center of the home. This research traces the impact of the writings of theorists such as Frederick Taylor, Georgie Boynton Child, Helen Binkerd Young, and Christine Frederick on the designs produced by the architects in the first quarter of the 20th century.  Frederick’s work took the concept of an efficient kitchen to a new level applying movement studies and introducing new ideas to the kitchen layout and arrangement.  In a properly laid out and equipped kitchen, steps were saved by placing kitchen cabinets, ovens and stoves, refrigerators and sinks where they were needed in the sequence of food preparation and delivery to dining table as well as clean up after the meal.  In her books, she also provided advice on a variety of considerations, such as appliances and accessories, lighting and ventilation; materials, finishes and color; and appliances and equipment.  In 1919 a group of architects dedicated to improving the housing stock in the United States through good design banded together to form the Architects’ Small House Service Bureau (ASHSB.  Their first plan book, How to Plan Finance and Build your Home published in 1921, also encouraged labor-saving kitchen design and provided advice on kitchen design. The research reported here assesses how the influence of Frederick and Boyton’s advice as reflected in the work of and interpreted by Helen Binkerd Young is demonstrated in the kitchen designs of the ASHSB’s first plan book. A plan content analysis instrument, developed using Frederick’s writings and edited to include other variables from Young and Child, is used to analyze the 99 kitchens and two essays in the ASHSB’s plan book.  The plans and accompanying comments evidence enthusiasm for

  15. NBS+_PH2 - NATIONAL BUREAU OF STANDARDS PARAHYDROGEN PROPERTIES DATABASE

    Science.gov (United States)

    Walton, J. T.

    1994-01-01

    The National Bureau of Standards Parahydrogen Properties Database (NBS+_PH2) program was developed to provide selected parahydrogen thermal and transport properties which match the 1981 NBS parahydrogen data. The program was created to be linked with propulsion simulation programs which require a parahydrogen model which can cover a wide range of pressures. NBS+_PH2 can provide data on parahydrogen for pressures from 1E4 to 1.6E7 Pa and temperatures from 20 degrees to 10000 degrees K. NBS+_PH2 is set up as a single FORTRAN subroutine. When pressure and temperature or enthalpy are sent to it through the FORTRAN call statement, the thermodynamic and transport properties at the given conditions are returned to the calling program. Linear interpolation is used to calculate between database entries when necessary. NBS+_PH2 can provide the following parahydrogen properties: density, thermal conductivity, viscosity, Prandtl number, enthalpy, specific heat, and speed of sound. NBS+_PH2 is a database program written in FORTRAN 77 and is designed to be machine independent. Although a user-interactive test program for accessing NBS+_PH2 is provided in the distribution package, NBS+_PH2 is intended to be linked with simulation programs. The database and interactive test program have been used successfully on a Sun4 series computer running UNIX, an IBM PC series compatible computer running MS-DOS (using Lahey F77L), and a DEC VAX running VMS. The standard distribution medium for this program is a 5.25 inch 360K MS-DOS format diskette. The contents of this diskette are compressed with the PKZIP archiving tools. The program to uncompress the files, PKUNZIP.EXE, is included on the diskette. A sample MS-DOS executable is provided. NBS+_PH2 is also available on a .25 inch streaming magnetic tape cartridge in UNIX tar format and a 9-track 1600 BPI magnetic tape in DEC FILES-11 format. Documentation is included in the price of the program. NBS+_PH2 was developed in 1992. UNIX is a

  16. Philippine Mining Capitalism: The Changing Terrains of Struggle in the Neoliberal Mining Regime

    Directory of Open Access Journals (Sweden)

    Alvin A. Camba

    2016-06-01

    Full Text Available This article analyzes how the mining sector and anti-mining groups compete for mining outcomes in the Philippines. I argue that the transition to a neoliberal mineral regime has empowered the mining sector and weakened the mining groups by shifting the terrains of struggle onto the domains of state agencies and scientific networks. Since the neoliberal era, the mining sector has come up with two strategies. First, technologies of subjection elevate various public institutions to elect and select the processes aimed at making mining accountable and sensitive to the demands of local communities. However, they often refuse or lack the capacity to intervene effectively. Second, technologies of subjectivities allow a selective group of industry experts to single-handedly determine the environmental viability of mining projects. Mining consultants, specialists, and scientists chosen by mining companies determine the potential environmental damage on water bodies, air pollution, and soil erosion. Because of the mining capital’s access to economic and legal resources, anti-mining communities across the Philippines have been forced to compete on an unequal terrain for a meaningful social dialogue and mining outcomes.

    The Pike Hill Copper Mine Superfund Site in the Vermont copper belt consists of the abandoned Smith, Eureka, and Union mines, all of which exploited Besshi-type massive sulfide deposits. The site was listed on the U.S. Environmental Protection Agency (USEPA) National Priorities List in 2004 due to aquatic ecosystem impacts. This study was intended to be a precursor to a formal remedial investigation by the USEPA, and it focused on the characterization of mine waste, mine drainage, and stream sediments. A related study investigated the effects of the mine drainage on downstream surface waters. The potential for mine waste and drainage to have an adverse impact on aquatic ecosystems, on drinking- water supplies, and to human health was assessed on the basis of mineralogy, chemical concentrations, acid generation, and potential for metals to be leached from mine waste and soils. The results were compared to those from analyses of other Vermont copper belt Superfund sites, the Elizabeth Mine and Ely Copper Mine, to evaluate if the waste material at the Pike Hill Copper Mine was sufficiently similar to that of the other mine sites that USEPA can streamline the evaluation of remediation technologies. Mine-waste samples consisted of oxidized and unoxidized sulfidic ore and waste rock, and flotation-mill tailings. These samples contained as much as 16 weight percent sulfides that included chalcopyrite, pyrite, pyrrhotite, and sphalerite. During oxidation, sulfides weather and may release potentially toxic trace elements and may produce acid. In addition, soluble efflorescent sulfate salts were identified at the mines; during rain events, the dissolution of these salts contributes acid and metals to receiving waters. Mine waste contained concentrations of cadmium, copper, and iron that exceeded USEPA Preliminary Remediation Goals. The concentrations of selenium in mine waste were higher than the average composition of eastern United States soils. Most mine waste was

    Air quality permits are required for the construction of all new surface mining operations. An air quality permit requires a surface mining operation to estimate the type and amount of pollutants the facility will produce. During surface mining the most common pollutant is particulate matter having an aerodynamic diameter less than 10 microns (PM10). The Industrial Source Complex (ISC3) model, created by the United States Environmental Protection Agency (U.S. EPA)...
