Abstract
The Bureau of Mines investigated mine subsidence caused by recent underground mining, estimated the extent of damages, and formulated a procedure for evaluating subsidence costs. On the basis of the quantity of material removed from beneath the surface, bituminous coal mining currently causes more extensive subsidence problems than mining of other minerals; costs are highest in areas such as western Pennsylvania where urban and suburban development and related types of land use conflict with mineral recovery. The Bureau of Mines estimated subsidence costs, including surface damages and control costs, for a 12-county area in western Pennsylvania for 1968. Total surface damages attributable to the underground production of bituminous coal in the 1-year period were $295,000; in addition, 12.4 million tons of coal, valued at $4.3 million, was left in place to minimize potential surface damage. Of the total subsidence cost ($4.6 million), $2.7 million was classified as external or social costs, not reflected in the market value of bituminous coal; this averaged $0.05 Per ton of production, or slightly less than 1 percent of the market value.
