Openpit mines are characteristically engorged until either the mineral resource is exhausted, or a mounting ratio of overburden to ore makes more mining uneconomic. When this occurs, the exhausted mines are at times converted to landfills for disposal of solid wastes.
Stripping ratio The ratio of tonnes removed as waste relative to the number of tonnes of ore removed from an openpit mine. Strip mine An openpit mine, usually a coal mine, operated by removing overburden, excavating the coal seam, then returning the overburden. Subbituminous A black coal, intermediate between lignite and bituminous.
