摘　　要：本文根据麦地掌煤矿地质勘探报告及生产记录,从地质特征、含水层、隔水层、充水水源、充水通道等方面综合分析了矿区水文地质特征及充水影响因素。结果表明矿井充水水源主要有山西组砂岩裂隙水、奥陶系岩溶水、采空区积水、大气降水和地表水,地表水和大气降水对矿井充水呈现季节性,充水通道主要为断层、陷落柱以及采煤导水裂隙。现开采煤层2号煤水文地质条件复杂程度中等,日常开采要做好采空区探查、汛期度汛、日常涌水疏排、导水构造提前探测等工作。According to the geological exploration report and production record of Maidizhang Coal Mine,this paper comprehensively analyzed the hydrogeological characteristics and influencing factors of water filling in the mining area from the aspects of geological characteristics,aquifer,aquifuge,water filling source and water filling channel.The results showed that the main sources of mine water filling were sandstone fissure water of Shanxi Formation,Ordovician karst water,accumulated water in goaf,atmospheric precipitation and surface water.Surface water and atmospheric precipitation were seasonal to mine water filling.The water filling channels were mainly faults,collapse columns and coal mining water flowing fissures.The hydrogeological conditions of No.2 coal seam were medium in complexity,which was the current mining coal seam.In daily mining,it was necessary to do a good job in goaf exploration,passing through flood season,daily water inflow drainage and early detection of water conducting structure.
