摘　　要：以某矿拟采工作面为例,通过分析工作面的水文地质条件和采矿条件,确定采用分层充填开采方案.根据岩层移动理论,计算分层充填开采条件下防水安全煤岩柱高度为30.64 m,分层充填开采下F3断层防水安全煤岩柱宽度为60 m.通过计算和分析,采用分层充填开采和F3断层防隔水煤岩柱宽度留设60 m的综合防治措施下,可以大大降低采动破坏对F3断层的"活化"影响,最终确认该矿水库下采煤具有安全可行性.Taking a working face in a coal mine as example,this paper uses the hierarchical filling technology by analyzing the geological and mining conditions of the working face. According to the theory of strata movement,it calculates the height of waterproof coal and rock pillars is 30. 64 m by the hierarchical filling technology,and the height of waterproof coal and rock pillars is 60 m under F3 fault conditions. After calculation and analysis,if the mine uses the hierarchical filling technology and remaining 60 m coal block is adopted,it can greatly reduce ＂activation ＂effect of the F3 fault by mining damage,thus mining under the reservoir is feasible in security.
