Coal mining probably results in a greater disturbance to the geologic conditions of an area than any other form of mining. This is due primarily to the nature of the coal deposits, which are commonly extensive, covering large areas and consisting of multiple seams extending over significant vertical intervals. Surface mining results in the disturbance of the ground surface and shallow subsurface materials over large areas. Reclamation of these mines generally results in subdued versions of the original landforms, rerouted drainage systems, and disrupted subsurface materials. Underground mines may be far more extensive, creating nearly continuous subsurface workings, which may result in postmining effects such as subsidence, mine pools, mine fires, and the accumulation of gases. Both mining types also affect surface and underground water, generally resulting in the deterioration of water quality and often capturing surface flow and changing, at least temporarily, groundwater levels. The following description concerns coal mining in the conterminous United States, although the changes in geologic conditions could be applicable in any coal mining region in the world.
