摘　　要：基于矿井的扩建、下组煤延深开采,完善的下组煤水文地质资料能够使受水害威胁的煤层得到安全开采。某矿太原组灰岩含水层具有富水性较弱,且埋深较大的特征,该矿通过利用已有的水文地质资料,结合井下长期涌水点的观测数据,对该矿下组煤水文地质补勘进行研究。Based on the expansion and deepening of mine mining lower coal,the perfection of coal hydrogeology data is an necessary guarantee for safe mining of coal seam where is threatened by water disasters.A mine of Taiyuan formation limestone aquifer with rich water is weak,and the characteristics of the buried depth is larger,using the existing mine hydrogeological data,especially with the observation date of underground water for a long time point,to study the mining′s lower group of coal hydrogeology data.
