In locations where coal beds are thick and near the surface, such as in Wyoming, mining costs and coal prices tend to be lower than in locations where the beds are thinner and deeper, such as in Appalachia. The higher cost of coal from underground mines reflects the more difficult mining conditions and the need for more miners.

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. Open cast 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. Large open cast mines can cover an area of many square
