针对淮南某矿急倾斜煤层开采复杂的采矿地质条件，运用概率积分法对优化后的开采方案所引起 的地表沉陷进行研究，总结出急倾斜煤层开采重复采动所引起的厚冲积层地表沉陷的相关参数。所得结果 对现场开采及地表沉陷治理具有一定的指导作用，对于同类地质和开采条件的矿区具有重要参考价值。

According to the complex geologic condition of deep excavat ion in Huainan, probability-integral method is ewployed to study the for surface displacement due to coal extraction by optimization mining layouts.  Correlation parameters about subsidence under thick loose overburden and duplication mining are obtained. The results obtained may provide guidance for the subsidence-administrating. It is valuable of this paper to other coal mines which have similar geological and mining conditions.
