The term "open cast mining" is used most commonly in Great Britain. In the United States, open cast mining is usually called openpit or opencut mining.
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This ...
Coal mining, particularly in the case of opencut mines, requires that large areas of land are temporarily disturbed, and perhaps withdrawn from other productive uses such as agriculture, while the process of coal extraction is under land may, however, be returned to productive use after mining or even while mining in other parts of the area is still in progress (Figure ).
Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step bystep mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.
