摘要
为预防银堂煤矿生产中的突水问题,特别是下伏茅口组(P2m)岩溶强含水层的岩溶水对D煤层开采的影响,保证该煤矿第二水平(+700)采煤安全生产的需求。通过在巷道内施工3个水文地质钻孔进行抽水试验,证明茅口组岩溶水的富水性,并结合井田范围内含水层厚度、岩性和富水性,各隔水层厚度、岩性和阻水性能,来划分矿井水文地质类型,预测矿井正常涌水量和矿井最大涌水量。

Abstract
In order to prevent the water outburst problem in the production of Yintang Mine, especially the influence of karst water in the karst strong aquifer of the underlying Maokou Formation ( P2m ) on the mining of D coal seam, and ensure the safety production of the second level ( + 700 ) coal mining in the coal mine,the water abundance of karst water in Maokou Formation was proved through the construction of three hydrogeological drilling holes in the roadway for pumping test. Combined with the thickness, lithology and water abundance of each aquifer, and thickness, lithology and water-blocking performance of each aquiclude in the mine field, the hydrogeological types of the mine were divided, and the normal water inflow and the maximum water inflow of the mine were predicted.
