It is estimated that through 1975, there were 1.69 x 10/sup 9/m/sup 2/ (418,000 acres) of urban land threatened by potential subsidence due to mining with a value of over $12 billion (1973 dollars; USBM, 1979). With increased coal production to meet the energy needs of the nation, both these figures may be expected to increase. Hence greater attention to controlling surface damage due to subsidence is merited. In fact, the Surface Mining Control and Reclamation Act of 1977 (SMCRA) (Public Law 95-87) mandates that underground coal mining operators ''adopt measures consistent with known technology in order to prevent subsidence causing material damage to the extent technologically and economically feasible, maximize mine stability, and maintain the value and reasonably foreseeable use of such surface lands, ...'' There are four types of measures that may be adopted to control subsidence damage: Alterations in Mining Techniques, Post-Mining Stabilization, Architectural and Structural Design, Comprehensive Planning. Each of these encompasses several methods which are discussed.
