摘　　要：针对深部煤炭开采严重受底板高承压水威胁的现实问题,为进一步认识工作面底板突水机理,从底板岩层的不同组合出发,通过力学分析与数值模拟,分析底板不同岩层组合对底板的破坏深度、破坏方式的影响。为实现承压水上安全采煤提供依据。For realistic problem that floor high pressure water serious threats the deep coal mining, for further understanding floor water working mechanism, this paper studies the destruction of the floor from different combination of floor strata, by mechanics analysis and numerical simulation, the paper analyzes the influence of different combination of floor strata on damage depth, damage ways, which provides a reference for realizing safety mining above confined water.
