    1983-06-01

    Worldwide, there are numerous conveyorized surface mines successfully operating today. Each surface mine is unique and requires a custom made system which ideally begins as part of the mine development plan. When properly applied, conveyorized systems can offer major cost savings in both capital costs and operating and maintenance costs. With modern technology, both required availability and flexibility have been satisfied on the many currently operating mines. Conveyorized systems offer a valuable ''tool'' which when combined with the other proven mining technology results in the most efficient surface mine operations which spells lower costs and higher profits.

    A sample of five mines were observed as part of a study to determine the magnitude and sources of environmental noise from surface mining operations and to identify noise abatement methods. These mining operations consisted of: a Minnesota iron ore mine, Midwestern and Appalachian coal mines, a Missouri clay pit operation, and a Texas limestone quarry. These operations are typical of Eastern and Midwestern mining activities. This paper highlights the findings of the noise measurement portion of that study.

  3. Spectral methods to detect surface mines

    Over the past five years, advances have been made in the spectral detection of surface mines under minefield detection programs at the U. S. Army RDECOM CERDEC Night Vision and Electronic Sensors Directorate (NVESD). The problem of detecting surface land mines ranges from the relatively simple, the detection of large anti-vehicle mines on bare soil, to the very difficult, the detection of anti-personnel mines in thick vegetation. While spatial and spectral approaches can be applied to the detection of surface mines, spatial-only detection requires many pixels-on-target such that the mine is actually imaged and shape-based features can be exploited. This method is unreliable in vegetated areas because only part of the mine may be exposed, while spectral detection is possible without the mine being resolved. At NVESD, hyperspectral and multi-spectral sensors throughout the reflection and thermal spectral regimes have been applied to the mine detection problem. Data has been collected on mines in forest and desert regions and algorithms have been developed both to detect the mines as anomalies and to detect the mines based on their spectral signature. In addition to the detection of individual mines, algorithms have been developed to exploit the similarities of mines in a minefield to improve their detection probability. In this paper, the types of spectral data collected over the past five years will be summarized along with the advances in algorithm development.

    Johnson, T.K.

    1990-12-31

    Due to concern over potential impact of surface coal mining on a traditional elk calving ground, Colorado Yampa Coal Company conducted a six and one half year study from 1981 to 1987 to monitor elk calving behavior in connection habitat disturbance resulting from mining. The specific objectives were to: (1) determine if productivity of elk is changed as they are displaced from a traditional calving area; (2) determining what fidelity they exhibit to calving areas; and (3) describe the physical and vegetation characteristics of elk calving areas. During the study, 448 elk captures were recorded, 294 individual elk were tagged, 75 of which received radio transmitters. The radio transmitter collared elk were relocated 4,583 times. Telemetry work on the 75 individual elk revealed no negative impacts on elk using the mine site. Productivity, calving home range size and fidelity, and habitat utilization patterns between elk using the mine site and control elk were not significantly different. There has been no indication that elk are abandoning mine areas. Aspen habitats directly adjacent to active mining continue to be selected for during the late spring and summer. Reclaimed sites are used in proportion to their availability during spring and summer and are selected for during the fall and early winter. In addition, a large amount of information on cow elk mortality, summer and winter ranges, migration patterns and habitat utilization was obtained.

  10. Geotechnical considerations in surface mine reclamation

    SciTech Connect

    Kuhn, A.K.

    1999-07-01

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

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

    During this quarter a general forest monitoring program was conducted to measure treatment effects on above ground and below ground carbon C and Nitrogen (N) pools for the tree planting areas. Detailed studies to address specific questions pertaining to Carbon cycling was initiated with the development of plots to examine the influence of mycorrhizae, spoil chemical and mineralogical properties, and use of amendment on forest establishment and carbon sequestration. Efforts continued during this period to examine decomposition and heterotrophic respiration on C cycling in the reforestation plots. Projected climate change resulting from elevated atmospheric carbon dioxide has given rise to various strategies to sequester carbon in various terrestrial ecosystems. Reclaimed surface mine soils present one such potential carbon sink where traditional reclamation objectives can complement carbon sequestration. New plantings required the modification and design and installation on monitoring equipment. Maintenance and data monitoring on past and present installations are a continuing operation. The Department of Mining Engineering continued the collection of penetration resistance, penetration depth, and bulk density on both old and new treatment areas. Data processing and analysis is in process for these variables. Project scientists and graduate students continue to present results at scientific meetings, tours and field days presentations of the research areas are being conducted on a request basis.

    The 2002-2003 Department of Energy plantings amounted to 164 acres containing 111,520 tree seedlings in eastern and western Kentucky. Data gathered on these trees included an inventory to determine survival of all planted species. A sub-sample of seedlings was selected to assess the height and diameter of individual species of seedlings established. Additional efforts involved collection of soil sample and litter samples, analysis of herbaceous ground cover from vegetation clip plots and leaf area on each tree species, and development of tissue collections. All areas were sampled for penetration resistance, penetration depth (or depth to refusal), and bulk density at various depths. Rain fall events and flow rates were recorded. The water quality of runoff samples involved the determination of total and settleable solids and particle size distribution. A study was initiated that will focus on the colonization of small mammals from forest edges to various areas located on reclaimed surface mines. This effort will provide a better understanding of the role small mammals and birds have in the establishment of plant communities on mine lands that will be useful in developing and improving reclamation techniques.

    Wildlife management, surface mining, and regional planning historically have had conflicting missions. The cooperative public/private venture which created the Robinson Forest and Cyprus-Amax Wildlife Management Areas is presented as an example of how a regional perspective encourages a symbiotic relationship among these functions. Wildlife management areas, as either an interim or final land use, are shown to incorporate development concepts which benefit the general public, the coal industry, and the environment. Examining the regional pattern of wildlife management areas and refuges confirms the appropriateness of the subject site for this use. It is suggested that the pattern of mined lands can be studied to identify other sites with potential to provide linkages between a wildlife habitat areas and encourage reclamation of such sites to the {open_quotes}fish and wildlife{close_quotes} postmining land use. Such reclamation strategies should be pursued within a long-term planning framework. More research is needed to recreate specific habitat types on drastically disturbed land and planning is needed to assure that sensitive habitats or species are located away from zones likely to undergo future development. Use of geographic information systems to integrate existing environmental information could make such studies more effective. 14 refs., 7 figs.

    Soil is a resource that is for all practical purposes nonrenewable. Natural soils have been formed over periods of thousands of years, although with intensive management and with inputs of nutrients and conditioners this time could be reduced.Coal is another precious resource, of critical importance as an interim fuel for perhaps the next hundred years or so, until renewable energy resources based on nuclear fusion or solar energy can become economic and widespread. Surface mining is the most efficient method for obtaining coal at lowest cost. But it disturbs the soil and takes it out of agricultural production for many years or decades, and sometimes forever, unless the land is properly restored at considerable cost.

The approval of two experimental practices associated with this research by the United States Office of Surface Mining was a major accomplishment during this period of time. These experimental practices will eventually allow for tree planting on long steep slopes with loose grading systems and for the use of loose dumped spoil on mountain top removal areas with no grading in the final layer of rooting material for tree establishment.

  16. Abandoned Mine Detection in Western Pennsylvania Using Surface Wave Data

    NASA Astrophysics Data System (ADS)

    Miller, B.

    2015-12-01

    Abandoned mines throughout the Appalachian region of the United States have been recognized as problematic. Resource extraction from these mines has long ceased and few, if any, documents pertaining to these operations exist. Over time support structures internal to the mines may collapse and lead to subsidence, potentially damaging surface structures. A non-invasive, surface deployed seismic method to detect undisclosed, abandoned near-surface mines would be beneficial as a first step to remediation. The use of seismic surface waves to analyze the upper several tens of meters of the subsurface has become an important technique for near-surface investigations and may provide a method for detection of near-surface, abandoned mine shafts. While there are many undocumented abandoned mines throughout the Appalachians one known example exists within Butler County, Pennsylvania. Although little is known about the overall operation there is limited documentation which provides information as to the location of the mine tunnels. Currently there is no recognized surface subsidence associated with the mine however documents indicate that the abandoned mining operations have an estimated depth ranging from twenty to fifty feet. To assist with acquisition a seismic land streamer was constructed. Use of a land streamer increases the speed, ease and efficiency required to perform a seismic survey. Additionally the land streamer allows for the acquisition of seismic surface waves which were analyzed using the Multichannel Analysis of Surface Waves (MASW) method. Data were acquired by conducting multiple, adjacent surveys perpendicular to the suspected location of abandoned mine tunnels. Throughout the survey area to a depth of approximately 15 meters, shear wave velocities range between approximately 200-1200 m/s. Based upon shear wave velocity changes within the profile anomalies have been identified corresponding to the contrast between the suspected mined, and unmined, areas.

    Originally published in 2001 this updated report provides a definition of the market for large rigid haulers in surface mining. The analysis covers changes to the mining market segments buying these machines including the gains made by coal producers, retrenchment in copper mining, the consolidation taking place among gold mining companies, and the expansion of iron ore producers in Australia and Brazil. It includes a detailed accounting of 2001 truck shipments, and an analysis of trends in the Ultra-truck segment. It concludes with a revised forecast for shipments through 2006. 12 charts, 56 tabs., 2 apps.

  9. Evaluation of hydraulic coal transport system concepts for surface mines

    SciTech Connect

    Roberge, J.; Stoukidis, M.; Rubin, L.; Burnett, M.

    1981-11-01

    Coal haulage from the pit of United States surface mines is most often accomplished with truck haul transportation schemes. The demand for domestic production of coal is expected to increase greatly over the next decade. Efforts to restrain and curtail increasing power production costs will require optimum productivity within the coal producing industry. The objective of this program was to develop concepts for in-pit hydraulic transport systems for surface coal mines that will permit significant increases in coal extraction and pit haulage productivity as compared to truck haulage. Large particle coal transport was demonstrated to be the most desirable for central and western United States surface mines. Three conceptual hydrotransport systems, including a centrifugal pump, jet pump and ventilated inducer system, were developed for each of two currently active mining operations. General and site-specific design parameters were developed for each of the conceptual hydrotransport systems. A detailed economic comparison of capital and operating and maintenance costs for each of the hydrotransport systems was made with the existing truck haul operations. An increase in haulage productivity of approximately 19% was demonstrated for the central surface mine, while that of the western surface mine increased by more than 180%. Included in this report is a bibliography containing over 600 citations pertinent to hydraulic transport of coal.

    Mine waste and mine reclamation are topics of major interest to the mining industry, the government and the general public. The publication and its companion volume are the proceedings of a conference held in Pittsburgh, April 19-21, 1988. There were nine sessions (50 papers) that dealt with the geochemistry, hydrology and problems of mine waste and mine water, especially acid mine drainage. The nine sessions (43 papers) that dealt with reclamation and restoration of disturbed lands, as well as related policy issues, are included in volume 2. Volume 2 also contains the ten papers that pertained to control of subsidence and mine fires at abandoned mines. Poster session presentations are, in general, represented by abstracts.

  1. Characteristics of bird communities on surface mine lands in Pennsylvania

    NASA Astrophysics Data System (ADS)

    Brenner, Fred J.; Kelly, Jeffrey

    1981-09-01

    A variety of species was observed as either visitors, permanent, or summer residents on surface mines with different ecological adaptations. Passerine species were the most prevalent of the 25 families represented. Bird communities as well as individual species were correlated with the structure and species of vegetation on the mines. The composition of the bird communities changed in response to successional vegetation stages from grassland to forest communities.

    2004-05-19

    The January-March 2004 Quarter was dedicated to tree planting activities in two locations in Kentucky. During year one of this project there was no available mine land to plant in the Hazard area so 107 acres were planted in the Martin county mine location. This year 120 acres was planted in the Hazard area to compensate for the prior year and an additional 57 acres was planted on Peabody properties in western Kentucky. An additional set of special plots were established on each of these areas that contained 4800 seedlings each for special carbon sequestration determinations. Plantings were also conducted to continue compaction and water quality studies on two newly established areas as well as confirmed measurements on the first years plantings. Total plantings on this project now amount to 357 acres containing 245,960 tree seedlings.

  15. Satellite data for surface-mine inventory. [in Maryland

    NASA Technical Reports Server (NTRS)

    Anderson, A. T.; Schultz, D.; Buchman, N.; Nock, M.

    1976-01-01

    To determine the feasibility of satellite data for surface-mine inventory, particularly as it applies to coal, a case study was conducted in Maryland. A band-ratio method was developed to measure disturbed surface areas, and it proved to be extendible both temporally and geographically. This method was used to measure area changes in the region over three time periods from September 1972 through July 1974 and to map the entire two-county area for 1973. For mines ranging between 31 and 244 acres (12 to 98 hectares) the measurement accuracy of total affected acreage was determined to be 92%. Mines of 120 acres (50 hectares) and larger were measured with greater accuracy, some within one percent of the actual area. The ability to identify, classify, and measure strip-mine surfaces in a two-county area (1,541 square kilometers - 595 square miles) of western Maryland was demonstrated through the use of computer processing. On the basis of these results the use of LANDSAT satellite data and multilevel sampling of aircraft and field verification inspections, multispectral analysis of digital data is shown to be an effective, rapid, and accurate means of monitoring the surface mining cycle.

  16. Reactivation of landslides by surface subsidence from longwall mining

    SciTech Connect

    Iannacchione, A.T.; Ackman, T.E.

    1984-12-01

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

    The first quarter of 2004 was dedicated to tree planting activities in two locations in Kentucky. During the first year of this project there was not available mine land to plant in the Hazard area, so 107 acres were planted in the Martin County mine location. This year 120 acres were planted in the Hazard area to compensate for the prior year and an additional 57 acres were planted on Peabody properties in western Kentucky. Additional sets of special plots were established on each of these areas that contained 4800 seedlings each for carbon sequestration demonstrations. Plantings were also conducted to continue compaction and water quality studies on the newly established areas as well as continual measurements of the first year's plantings. Total plantings on this project now amount to 357 acres containing 245,960 seedlings. During the second quarter of this year monitoring systems were established for all the new research areas. Weather data pertinent to the research as well as hydrology and water quality monitoring continues to be conducted on all areas. Studies established to assess specific questions pertaining to carbon flux and the invasion of the vegetation by small mammals are being quantified. Experimental practices initiated with this research project will eventually allow for the planting on long steep slopes with loose grading systems and allow mountain top removal areas to be constructed with loose spoil with no grading of the final layers of rooting material when establishing trees for the final land use designation. Monitoring systems have been installed to measure treatment effects on both above and below ground carbon and nitrogen pools in the planting areas. Soil and tissue samples were collected from both years planting and analyses were conducted in the laboratory. Examination of decomposition and heterotropic respiration on carbon cycling in the reforestation plots continued during the reporting period. Entire planted trees were extracted

    A monitoring program to measure treatment effects on above ground, and below ground carbon and nitrogen pools for the planting areas is being conducted. The collection of soil and tissue samples from both the 2003 and 2004 plantings is complete and are currently being processed in the laboratory. Detailed studies have been initiated to address specific questions pertaining to carbon cycling. Examinations of decomposition and heterotropic respiration on carbon cycling in the reforestation plots were continued during this reporting period. A whole-tree harvesting method was employed to evaluate carbon accumulation as a function of time on the mined site. The trees were extracted from the sites and separated into the following components: foliage, stems, branches, and roots.

    1994-01-01

    The report presents the results of an emissions sampling program to measure airborne particulate matter released from the activities conducted at open pit coal mines in the western United States. The principal objective of the study was to compare field measurements against available emission factors for surface coal mines and to revise the factors as necessary. The field measurements were conducted during the fall of 1992 at the Cordero surface coal mine in the Powder River Basin of Wyoming. A total of 36 PM-10 emission tests, distributed over various sources and five test sites, was performed. The report presents the sampling methodology used, the emission measurement results, the ambient monitoring results, the results of the reexamination of current emission factors, and recommended emission factor models for haul truck travel, light-duty vehicle travel and scraper travel on upaved roads.

    Willison, L.R.

    1986-07-01

    A deep mining area, located in the rugged woodland hills of central West Virginia, was transformed into a beehive of activity as a major new mine and preparation plant was constructed on a very tight deadline. By the time the mine was on line, BethEnergy Mines had spent $40 million to develop the two million tpy (ton per year) surface coal mining complex. In early 1984 not a stick of timber had been cut. But within a very short time (coal-wise) there was a mining area; a 600-tph heavy media cyclone preparation plant, with 36,000 and 24,000 tons of raw and clean coal storage respectively; three miles of haul roads and access roads; a 64,000-ton clean coal stocking facility with a 4000-tph reclaim system that feeds a batch-weighing, floodloading, unit-train loadout facility; a 3.5-mile railroad spur and loop; and all incidental infrastructure. This feat entailed moving more than four million cu-yd of earth, building the preparation plant and loadout facility from ground to operating in six moths, and constructing a railroad spur bridging a major highway.

    This paper depicts the method used to quantify the environmental impact of mining activities in surface mine projects. The affected environment was broken down into thirteen components, such as Human health and immunity, Surface water, Air quality, etc. The effect of twenty impacting factors from the mining and milling activities was then calculated for each Environmental Component. Environmental assessments are often performed by using matrix methods in which one dimension of the matrix is the "Impacting Factor" and the other one is the "Environmental Components". For the presented matrix method, each Impacting Factor was first given a magnitude between -10 and 10. These factors are used to set up a matrix named Impacting Factor Matrix, whose elements represent the Impacting Factor values. The effects of each Impacting Factor on each Environmental Component were then quantified by multiplying the Impacting Factor Matrix by Weighting Factor Matrix. The elements of the weighting factors matrix reflect the effects of each Impacting Factor on each Environmental Component. The outlined method was originally developed for a mining and milling operation in Iran, but it can successfully be used for mining ventures and more general industrial activities in other countries in accordance to their environmental regulations and laws.

  5. Enhanced Surface Mine Reclamation Using Geomorphic Landform Principles

    NASA Astrophysics Data System (ADS)

    Sears, A.; Hopkinson, L. C.; Bise, C.; Quaranta, J.

    2013-12-01

    Approximately 40% of operating mines in West Virginia are surface mines, producing approximately 50 million tons of coal annually. Traditional surface mine techniques include end-dumping burden material removed from the surface into nearby valleys, resulting in valley fills with uniform slopes, terraces, and drainage ditches. These techniques provide the opportunity for improvement in the areas of stream loss, surface water infiltration and runoff, and downstream water quality. The objective of this research was to create alternative surface mine reclamation designs for a permitted valley fill. Four designs were created: i) dendritic drainage; ii) retrofit; iii) dendritic drainage with bench ponds; and iv) dendritic drainage with valley ponds. All designs were based on a permitted surface mine site (1.4 km2) in southern West Virginia. Characteristics such as stream length and cut/fill volume were compared among the four created designs, the traditional design, and the original pre-mined surface. Geomorphic landform principles including creating landforms with overall hydrologic balance were applied to the design permit area. The geomorphic landform design (GLD) resulted in approximately 5.3 km of created channel length, 5.7 x 107 m3 of fill material (same volume cut during mining), and was comprised of ridges, valleys, and channels. The same design principles were applied to the top surface of the traditional valley fill to create the retrofit design. The traditional valley fill (6.9 x 107 m3 volume) consisted of a level top surface with drainage ditches around the perimeter. Features of the retrofit GLD included complex slope profiles and a dendritic drainage pattern. The design resulted in 6.7 x 107 m3 of cut volume and 5.7 x 107 m3 of fill volume and approximately 8.4 km of stream length. The GLD design surface was used as the base for the surface water retention designs, which included a design with three bench ponds and one with three valley ponds. The bench

  6. Private and Social Costs of Surface Mine Reforestation Performance Criteria

    Sullivan, Jay; Amacher, Gregory S.

    2010-02-01

    We study the potentially unnecessary costs imposed by strict performance standards for forest restoration of surface coal mines in the Appalachian region under the Surface Mining Control and Reclamation Act of 1977 (SMCRA) that can vary widely across states. Both the unnecessary private costs to the mine operator and costs to society (social costs) are reported for two performance standards, a ground cover requirement, and a seedling survival target. These standards are examined using numerical analyses under a range of site productivity class and market conditions. We show that a strict (90%) ground cover standard may produce an unnecessary private cost of more than 700/ha and a social cost ranging from 428/ha to 710/ha, as compared with a 70% standard. A strict tree survival standard of 1235 trees/ha, as compared with the more typical 1087 trees/ha standard, may produce an unnecessary private cost of approximately 200/ha, and a social cost in the range of 120 to 208/ha. We conclude that strict performance standards may impose substantial unnecessary private costs and social costs, that strict performance standards may be discouraging the choice of forestry as a post-mining land use, and that opportunities exist for reform of reforestation performance standards. Our study provides a basis for evaluating tradeoffs between regulatory efficiency and optimal reforestation effort.
