四川珙县麻塘村煤矿水患研究及防治

摘要

Using the coal mine water filling factors analysis method and hydrogeological analogy method to research the coal mine flooding of Gong County, the analytical results show that the sandstone fissure water in the coal seam roof, which through mined-out water flowing fracture zone into tunnel,is the main source of water flooding,and the goaf water flow fractured zone is the main water channel. The water inflow is predicted by hydrologic geology analogy method,3 763. 2 m3/d of normal inflow and 7 051. 2 m3/d of maximum inflow in Matangcun coal;and 547. 2 m3/d of normal inflow and 864. 0 m3/d of maximum inflow in Gaoshi coal. According to the flooding characteristics of Matangcun coal mine,the prevention and control counter-measures aiming at flooding have proposed,and theoretical data for mine water prevention and control work have provided.%运用矿井充水因素分析法以及水文地质比拟法对珙县麻塘村煤矿进行水患研究,研究表明,通过采空导水裂隙带进入坑道的煤层顶板砂岩裂隙水是水患的主要充水来源,采空区是主要的过水通道；采用水文地质比拟法对涌水量进行预测,得出麻塘村煤厂与高石煤厂正常涌水量分别为3763．2 m3/d、547．2 m3/d,汛期最大涌水量分别为7051．2 m3/d、864 m3/d。针对麻塘村煤矿的水患特点,提出了有针对性的水患防治对策,为今后矿井开展防治水工作提供经验参考。
