The increases above 1975 levels for acid mine drainage and subsidence for the years 1985 and 2000 based on projections of current mining trends and the National Energy Plan are presented. No increases are projected for acid mine drainage from surface mines or waste since enforcement under present laws should control this problem. The increase in acid mine drainage from underground mines is projected to be 16 percent by 1985 and 10 percent by 2000. The smaller increase in 2000 over 1985 reflects the impact of the PL 95-87 abandoned mine program. Mine subsidence is projected to increase by 34 and 115 percent respectively for 1985 and 2000. This estimate assumes that subsidence will parallel the rate of underground coal production and that no new subsidence control measures are adopted to mitigate subsidence occurrence.
根据当前采矿趋势和国家能源计划的预测，给出了1985年和2000年酸性矿井排水和地面沉降超过1975年水平的增长情况。由于现行法律的执行应能控制这一问题，预计露天矿或废弃物产生的酸性矿井排水不会增加。预计到1985年，地下矿井酸性矿井排水将增加16%，到2000年将增加10%。2000年相对于1985年较小的增长反映了第95 - 87号公法废弃矿井计划的影响。预计1985年和2000年地面沉降将分别增加34%和115%。这一估计假设地面沉降将与地下煤炭产量的增长率同步，并且没有采取新的沉降控制措施来减轻沉降的发生。
