Basic Information about Surface Coal Mining in Appalachia

Oct 06, 2016 Once coal removal is complete, final regrading takes place and the area is revegetated. The operation is required to reclaim the mine to "AOC" or "approximate original contours" unless this requirement has been waived by the agency that has granted the Surface

Surface coal mining practice in China ScienceDirect

Sep 01, 2009 Surface coal mining technology, practice and development of mining systems are introduced since the founding of China. The development of surface coal mining systems can be classified into two stages: shovel-train mining system used as the major mining technology before 1980, combined mining systems have been used since 1980, that is, shovel-truck mining system used as

The development of surface coal mining in Indiana (1985

Reserves of surface-minable coal in Indiana are a great store of wealth whose exploitation since 1915 has transformed the physical and economic landscape of Indiana's southwestern counties. In studying the coal resources of Indiana, the Indiana Geological Survey has compiled much engineering, economic, historical, and geologic information on the surface-mining industry.

Once production is ongoing, mining will be primarily completed with hydraulic excavators which will remove material (overburden and coal) and feed trucks that will either deliver the coal for

e-WV Surface Mining

Mar 11, 2020 Later advances in diesel machinery, as well as improved highways and the development of large trucks, would free surface mines from the coal industry’s traditional reliance on railroads and allow the development of mines with much shorter life spans than underground mines.

In addition, strip mining is ecologically very destructive unless the mining company makes a conscious effort to restore the countryside. Strip mining is the process of scraping the coal from the top surface of the ground. The second phase in the evolutionary development of coal is lignite. Lignite is found in great quantities in the Western

DESCRIPTION OF TECHNIQUES TO DRILL, COMPLETE, AND

During surface mining of coal, the vegetation and overburden are removed, the coal is mined, and the overburden is replaced and the surface is reclaimed. After mining, the reclaimed spoil undergoes weathering, settling, and compacting for an unknown period of time before reaching equilibrium.

Ecosystem development and natural succession in surface

Biotic and abiotic factors involved in surface coal mine reclamation were evaluated on 81 mine sites in Mercer County, Pennsylvania, USA. Soil moisture and organic content were the two most important factors in determining the establishment and growth of vegetation on mined lands. Soil bacteria and fungi populations were also related to these soil conditions, and soil micro-organisms were

Coal National Geographic Society

Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.

CONTROL OF Mining and Blasting

The tendency of coal to self-heat is a function of both intrinsic factors (coal type, geological setting and environmental conditions) and extrinsic factors (mining related). Combustible matter can interact with the oxygen in the air at ambient temperature releasing

Coal: Research and Development to Support National Energy

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the
