复杂地质条件下煤矿地下水库建设研究

Research on Construction of Coal Mine Groundwater Reservoir under Complex Geological Conditions

针对西部煤矿主产区煤炭开采与水资源保护矛盾突出的问题,采用了煤矿地下水库建设技术实现矿井水保护与利用。以宁煤灵新煤矿为对象,研究在缓倾斜煤层条件下建设煤矿地下水库。水库建设地址位于井田开拓的一采区的北翼,总库容可达380万m^3,挡水坝体采用钢筋混凝土平板支墩坝。通过布置监测系统,可实现地下水库运行状况的数据采集和分析,为水库安全运行和维护提供有力保障。

Aiming at the prominent contradiction between coal mining and water resources protection in the main producing areas of western coal mines, the mine underground water reservoir construction technology was adopted to realize the protection and utilization of coal mining water. Taking Lingxin coal mine of Ningmei group as an object, the research is to construct the underground water reservoir of coal mine under the condition of gently inclined coal seam. The construction site of the reservoir is located in the north wing of the first mining area. The total storage capacity can reach 3.8 million m^3.The reinforced concrete slab pier dam is used for the retaining dam. By arranging a monitoring system,data collection and analysis of the operating conditions of the groundwater reservoir can be achieved,providing a strong guarantee for the safe operation and maintenance of the reservoir.
