摘　　要：研究断层区防水煤柱的留设具有重要的现实意义。文中通过对任楼煤矿F3和F4断层导水性分析,认为其为不导水断层,通过数值模拟和理论计算断层区煤层在开采影响下底板的破坏深度,考虑断层的性质,对断层进行了分段留设,为尽量开采煤炭资源提供了理论支持。There is important practical significance to research the remained water-proof coal pillars in the fault zone. Through analyzing the F3 ＆ F4 fault hydraulie conduct of Renlou Coal Mine, it is thought that it is the non-hydraulic conductivity fault, through numerical simulation and theoretical calculate of the fault zone in coal seam under the mining impact the depth of the floor damage in coal seam, the fault properties are considered, the fault is set to subleaving in order to maximiz the exploitation of coal resources to provide a theoretical support.
