摘要
本文对七元煤矿的水文地质条件进行了研究。通过对矿井含水层特征、隔水层特征、含水层间水力联系及地下水补径排条件分析,确定了矿井充水因素,并预测了矿井涌水量。煤矿开采81、15号煤层时主要受底板奥灰及太灰水威胁。
The hydrogeological condition of Qiyuan Mine was studied in this paper.Through the analysis of the mine aquifer characteristics,aquifuge characteristics,hydraulic connection between aquifers and groundwater recharge and discharge conditions,mine water filling factors were determined,and mine water inflow was predicted.The coal mine was mainly threatened by Ordovician limestone and Taiyuan formation limestone water when mined No.81 and No.15 coal seams.
