Computer aids for reclaiming eastern surface mines as rangelands
… concept was developed and demonstrated for coal surface mined lands. An objective weighting methodology was employed to determine the optimum forage species mixture to seed surface mined sites. With the optimum mixture determined, total costs for establishment, total monthly available dry matter, …

Small mammal use of abandoned surface mines in southwestern Virginia
Trapping was conducted on 12 abandoned contour surface mines in southwestern Virginia during the summer of 1976 to determine relationships between small mammal diversity and abundance and select vegetation and site factors. Eleven species of mammals were captured during four, six-night trapping …

A computer decision aid for reclaiming eastern abandoned surface mines
… aid for the reclamation of eastern abandoned surface mined lands. Edaphic, topographic, climatological, and economic factors provide the inputs to the model. By utilizing the present costs and benefits from representative reclamation practices, objective and efficient decisions can be made. …

Mapping Elaeagnus Umbellata on Coal Surface Mines using Multitemporal Landsat Imagery
… inhibit efforts to restore disturbed landscapes. Surface coal mines in the Appalachian Mountains are some of the most disturbed landscapes in North America. Moreover, there is not a comprehensive understanding of the land cover characteristics of post- mined lands in Appalachia. Better information …

Switchgrass potential on reclaimed surface mines for biofuel production in West Virginia
… Virginia contains vast expanses of reclaimed surface mine lands and could potentially benefit from the production of switchgrass as a biofuel feedstock. Furthermore, switchgrass production could satisfy Surface Mining Reclamation and Control Act of 1977 (SMCRA) requirements for reclamation …

Soil productivity model to assess forest site quality on reclaimed surface mines
The Surface Mining Control and Reclamation Act (SMCRA) of 1977 requires that mine operators reclaim mined land to achieve productivity levels equal to or greater than premined conditions. Presently, the standard for evaluating reforestation success is based solely on tree-seedling survival. This …

Diversity of ectomycorrhizal fungi on two reclaimed surface mines differing in soil properties
… on white pine (Pinus strobus) on two reclaimed surface mines in eastern Ohio. One site was acidic and metal-stressed, the other was alkaline. Completely different community composition was found on the two sites by PCR/ITS/RFLP analyses of field collected mycorrhizae. However, Shannon-Wiener …

Hydrologic system conceptualization, characterization, and quantification of the North Antelope and Rochelle surface mines and adjacent areas
Includes bibliographical references (pages 148-149).

Impacts of non-renewable resource extraction on shrubland songbird nest success and abundance
… it has historically seen high amounts of surface mining for coal and is currently experiencing prolific development of shale gas. Both of these practices alter local habitats and the landscape, and it is essential to understand their impacts on shrubland songbirds in order to inform …

The Importance Of Surface Mining As A Landscape Variable In Shaping Wild Bee Communities In Central Appalachian Forests
… in Southeastern Kentucky, U.S.A. where surface mining for coal is common. Data was analyzed using generalized linear mixed-effect models to detect the most important landscape scale variables, including mining, in shaping bee communities. Bee species richness was significantly lower on …

Effects of Silvicultural Treatments and Soil Properties on the Establishment and Productivity of Trees Growing on Mine Soils in the Appalachian Coalfields
… source in the U.S. for the foreseeable future. Surface mining for coal is one of the methods employed to extract this resource from below the ground. The process of surface mining removes native topsoils and any native vegetation that was support by these native soils. In the Appalachian …

Mountain top eco-industrial park: An eco-industrial, renewable energy approach for industrial park development
… complex: Mount Storm Power Plant and former surface mines. Extractive industries and energy production will be a theme within the design project. An Eco-Industrial Park model will be applied in looking to a sustainable energy future for the site and the region. The result of this …

Examining the Cover and Composition of the Successional Vegetation Mosaic of Pre-SMCRA Mined Landscapes in Southeast Ohio
This research examined 10 similar surface coal mines in southeast Ohio to assess the factors broadly influencing the cover and composition of the successional vegetation mosaic. Transects were surveyed on opposing north- and south-facing aspects within each mine to comprehensively characterize the …

Determining a Total Dissolved Solids Release Index from Overburden in Appalachian Coal Fields
… acid-forming overburden materials at coal mines in the region. However, the techniques to predict acid mine drainage potential may not adequately predict the release of total dissolved solids (TDS). High concentrations of TDS have been linked to a decrease in survival of aquatic …

Dynamo in the Desert: Energy Development and Environmental Contestation in the San Juan Basin, 1960-1985
This thesis examines coal-energy development in the San Juan Basin, which is located in the culturally rich and environmentally diverse Four Corners region. Between 1960 and 1985 intensive coal-energy development—in the form of strip mines and power plants—took place in the western portion of the …

Evaluation of Rope Shovel Operators in Surface Coal Mining Using a Multi-Attribute Decision-Making Model
Rope shovels are used to dig and load material in surface mines. One of the main factors that influence the productivity and energy consumption of rope shovels is the performance of the operator. Existing methods of evaluating operator performance do not consider the relationship between production …

Appalachian Surface Mine Reforestation Techniques: Effects of Grading, Cultural Treatments and Species Selection
Surface mining for coal in the Appalachian region has removed over 0.6 million Ha of mixed mesophytic forest. Successful reforestation would be beneficial, but questions remain concerning application of reclamation and reforestation methods on operational scales. Four experiments were performed …

Effect of Various Saturation Levels, Leaching Solution pH, and Leaching Cycle on Electrical Conductivity from Coal Mine Spoil Leachate
… research associated with Appalachian coal surface mines focused on acid mine drainage and reclamation. Recent studies suggest that electrical conductivity (EC) levels above 500 ?S cm-1 can impair Appalachian streams, shifting the focus towards limiting release of total dissolved solids …

Examining the Modifiable Areal Unit Problem: Associations Between Surface Mining and Birth Outcomes in Central Appalachia at Multiple Spatial Scales
… unit in health-related analyses. This study examines associations between surface mining and birth outcomes from 1989 to 2015 in Central Appalachia at the individual; postal; county; and county-sized, non-administrative scales. Evidence from previous studies suggests associations exist between …
