摘要
针对胡家河煤矿水害较为严重的现状,结合矿井地质及水文地质条件,对矿井充水水源、充水通道和充水强度进行分析,得出影响胡家河煤矿4#煤开采的主要含水层为白垩系砂岩含水层,其次为侏罗系弱富水含水层。结合各含水层空间关系与性质特征,形成胡家河煤矿的防治水技术体系,对指导矿井防治水工作有重要意义。
In view of the serious situation of water damage in Hujiahe Coal Mine, combined with the geological and hydrogeological conditions of the mine, the water source, channel and intensity of the mine water filling are analyzed. It is concluded that the main aquifer affecting the coal mining of the Hujiahe Coal Mine is the Cretaceous sandstone aquifer followed by the Jurassic weak water-rich aquifer. Based on the spatial relationship and property characteristics of each aquifer, the technical system of water control in Hujiahe Coal Mine is formed, which is of great significance to guide the prevention and control of mine water.
