通过对广源矿区水文地质、主要含水层、隔水层特征与矿井充水因素的分析,认为主要充水水源为大气降水,回采冒落产生的地表塌陷裂隙构成大气降水直接或间接入渗矿井的通道,老空水与老巷横向上的联系对矿井充水构成威胁。 According to the analysis of the hydrogeology, the main aquifer, the characteristics of aquifuge and the water filling factor in Guangyuan mine, it is considered that the main source of water for filling is the precipitation of the earth’s surface, and the surface subsidence fissures caused by the mining and falling off constitute atmospheric precipitation directly or indirectly into the mine Of the channel, the old empty water and the old alley horizontal linkages pose a threat to mine water.
