摘　　要：孙疃煤矿水文地质条件复杂,水害问题直接影响着煤炭资源的安全高效开采。基于水文地质背景资料,探讨了煤矿充水条件,并对煤矿涌水量的控制因素进行了系统分析。结果认为,属于新生界的松散层孔隙含水层、位于煤层之间的砂岩内裂隙含水层以及石灰岩岩溶-裂隙含水层是矿区的主要含水层。新生界的第四含水层,煤层顶底板砂岩裂隙含水层,灰岩岩溶-裂隙含水层以及老坑水是矿区充水的主要来源。地下水主要沿断层及构造裂隙、岩溶陷落柱、采动冒落带裂隙、底板受其承压水的影响而产生的破坏带裂隙等通道相矿井运移。煤矿月平均涌水量171.01m3/h,主要受煤层顶底砂岩裂隙富水性、断裂及构造裂隙以及采掘面积、煤产量和巷道掘进等开采因素影响,而大气降水、地表水受第四系更新统隔水层阻隔,与矿井涌水量没有关系。The hydrogeological condition in Suntuan coal mine is complicated, and water damage becomes a factor which directly threatens safety production in coal mines. Based on the study of hydrogeological background, the paper analyzed the conditions of water filling and controlling factors of water inflow in Suntuan coal mine. The results indicated that the primary water-bearing strata included Cainozoic unconsolidated porous aquifer, fissured aquifer inside sandstone between coal beds and limestone karst-fissured aquifer. The major source of water filling in the mining area were Cainozoic Quaternary aquifer, sandstone fissured aquifer on the top and bottom coal beds, limestone karst-fissured aquifer and the water in the old pit. The the main channels for underground water movement include main faults and structural fissures, karst collapse pillar, fissures in caving and mined zone,and damaged zone fisures caused by water pressure on bottom beds. Monthly average water inflow rate in the coal mine is up to 171.01m^3/h. The water inflow is mainly related to the watery sandstone fissures on the top and bottom coal beds, size of fractures and structural fissures as well as excavation area,coal production,and roadway tunneling. However, obstructed by Quaternary Pleistocene aquiclude, the meteoric and surface water hardly affect the water inflow rate in the mine.
