|Section 516 of Public Law (PL) 95-87, commonly known as the Surface Mining Control and Reclamation Act of 1977 (SMCRA), requires that underground coal mine operators must 'adopt measures consistent with known technology in order to prevent subsidence causing material damage to the ex- tent technologically and economically feasible, maximize mine stability, and maintain the value and reasonable foreseeable use of such surface lands, except in those instances where the mining technology used requires planned subsidence in a predict- able and controlled manner..." Implied in the constraints of Section 516 (b) (1 of SMCRA is a determination of what constitutes "material damage" to surface structures and renewable resource lands, and the capacity for sequential land use following underground mining. This Study was undertaken in an attempt to provide quantitative guidelines for estimating material damage to a wide variety of surface structures and renewable resource lands. Surface structures studied included buildings, bridges, railroads, highways. pipe- lines, d~, embankments, and water reservoirs. Damage criteria for buildings developed in this study along with details of the adopted methodology have been presented elsewhere (Bhattacharya et al.) (1). and will not be repeated here. Similar guidelines for renewable resource lands have also been discussed (Singh and Bhattacharya) (2)|
