Surface mining, including strip mining, openpit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

surface mining and the impacts on ground water are not understood well enough to be adequately predicted in many cases. An example of this is the lack of data docu­ menting groundwater quality before and after surface mining and reclamation at specific sites.

Fluid mining is extraction from natural brines, lakes, oceans, or underground waters; from solutions made by dissolving underground materials and pumping to the surface; from underground oil or gas pools; by melting underground material with hot water and pumping to the surface; or by driving material from well to well by gas drive, water drive, or combustion.

Definitions. (b) Surface mines include areas where mineral extraction from the surface or subsurface occurs by the auger method or by reworking mine refuse or tailings, when the disturbed area exceeds the size or height thresholds listed in (a) of this subsection.

OVERBURDEN: Layers of earth and rock covering a coal seam. In surface mining operations, overburden is removed using large equipment and is either used to backfill areas previously mined or is hauled to dumping areas. OZONE: A bluish, toxic gas with a pungent odor formed by three oxygen atoms rather than the usual two.
