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。
In order to improve the recovery rate of coal resources, the 32 mining area of Lugou Coal Mine is mostly located under the water body of Wuxing Reservoir. Through the calculation of the height of water-conducting fracture zone and the prediction of surface deformation, the feasibility of coal mining under water body in No.32 mining area of Lugou Coal Mine Were studied. The results show that coal mining in No.32 mining area will not have a direct impact on the water body of the reservoir. It is feasible to mine coal under water in No.32 mining area. It is suggested that the fault and hydrogeological exploration should be strengthened in the excavation process and a reasonable water-proof coal pillar should be set aside. According to the geology and mining conditions, a reasonable mining speed should be adopted.
