摘要
芦沟煤矿32采区大部分位于五星水库水体下,为了提高煤炭资源的回收率,通过导水裂缝带高度计算及地表移动变形的预计,对芦沟煤矿32采区水体下采煤的可行性进行了研究。结果显示,32采区煤炭开采不会对水库的水体造成直接的影响,32采区在水体下采煤是可行的。建议在采掘过程中加强断层及水文地质勘探,留设合理的防隔水煤柱;根据地质采矿条件,采用合理的开采速度。
The paper conducted feasibility study of coal mining under water in 32th district of Lugou coal mine, through the calculation of the height of water-conducting fractured zone and the expectation of ground movement and deformation, it was concluded that coal mining under water in the district would not cause direct impact on water in the reservoir and is feasible.
