In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. In many mineral industries, like coal industry, in open cast mines, coal can be extracted only after removing layers of soil, stone etc

Effects Of Mining on the Environment and Human Health

Strip mining accounts for about 40 percent of the world’s coal mines but in some countries, such as Australia, open cast mines make up 80 percent of mines. Even though it’s highly destructive, industry often prefers strip mining as it requires less labour and yields more coal than underground mining

Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling

Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use

In this method, the mine is opened from top completely and the process is also termed as “quarrying.” In this case, the principal factor to be considered before adoption of open cast mining is the overburden to coal ratio, the physical characteristics of the seam, topography, and continuity of operation. With increasing overburden to coal ratio, the cost of removal of overburden (known as stripping cost)
