摘　　要：金能煤业分公司矿井地处贺兰山北段山前冲积平原边缘,东临黄河。地表受山洪、黄河、采空塌陷积水等水体影响,地下受基岩中砂岩裂隙含水层、老空区积水危害,矿井水文地质条件复杂。历史上发生过多次突水。在分析研究矿井水文地质特征及充水因素的基础上,认为矿井涌水量主要来源是上水平、上区段采空区泄水及采空区灌浆后下部出水,其次是各含水层充水,再次是生产用水的排泄;煤层开采形成的冒落带、导水裂隙带,基岩裂隙,断层破碎带是主要的充水通道。并提出了切实可行的矿井防治水方法与对策,对金能煤业分公司和神华宁煤集团其他开采石炭-二叠系煤层矿井的防治水工作具有重要意义。A eoalmine of the Jinneng Coal Industry Branch Company is situated on the margin of Helan Mountains northern sector pied-mont alluvial plain, and the Yellow River to the east. Impact from mountain torrents, Yellow River, gob area surface subsidence pond- ing on the surface, while sandstone fissure aquifer, gob area ponding underground, thus have complicated coalmine hydrogeological con-dition. Multiple times of water bursting has been happened in history. Based on the mine hydrogeological characteristics and water fill- ing factor analytic studies, considered that the mine water inflow is mainly from upper levels, upper sublevels seepage and lower efflu- ent of gob area grouting, secondly aquifers inflow, thirdly drainage of production water; main water filling channels have caving zone, water conducted fissure zone, bedrock fissures and shattered fault zone. Finally put forward practical mine water control methods and countermeasures, thus have significance in water control of other Permo-Carboniferous eoalmines of Jinneng Coal Industry Branch Company and Shenhua Ningxia Coal Industry Group.
