摘　　要：运用FLAC^(3D)数值分析软件,对工作面开采过程中岩层的垂直应力场、最大主应力场以及破坏场的分布情况以及试验矿区的覆岩破坏规律进行了深入研究.分别采用三种模拟方案,对裂缝有无水压力作用条件下覆岩破坏的发育情况进行分析,得出在较高水压情况下,覆岩破坏高度显著增加且数值模拟结果与实测数据基本相符.The FLAC^3D numerical analysis software is adopted to analyze the vertical force zone, the major stress and the distribution of the failure zone in the working face production process and the damaying rules of over- burdes strata are researched. Three simulation methods are adopted to explore the development situation of over-burden strata destruction under the crevices with or without water pressure. The results show that the numerical simulation results are basically consistent with the observed data.
