摘　　要：李村煤矿为新建矿井,位于潞安矿区西部深埋区,计划开采山西组3号煤,矿井水害为煤层顶板砂岩裂隙水。在分析矿井水文地质条件的基础上,采用瞬变电磁探测成果,对3号煤顶板富水规律进行了研究,认为首采区的各含水层的富水区与构造相差程度高,且为片状分布,主要分布于两个较大倾斜构造和X7陷落柱及工业广场南部的陷落柱附近。采用富水系数法和解析法对井井底车场和首采工作面的涌水量进行了预测,认为富水系数法计算的涌水量成果较为可靠;利用承压含水层非稳定流定降深法对首采区1302工作面的涌水量进行了动态预测,发现顶板砂岩含水层是以疏干充水为特征。该研究对李村煤矿矿井建设及采区生产的防治水工作具有指导意义,同时对于山西潞安矿区西部煤层深埋区新建矿井排水系统及矿井防治水措施具有重要的参考作用。The Licun coalmine is a newly built coalmine situated in deep buried part of the western Luan mining area and planned to extract coal seam No.3 in the Shanxi Formation. The possible coalmine water flooding may come from roof sandstone fissure water. Based on mine hydrogeological condition analysis, using transient electromagnetic prospecting results, carried out study on No.3 coal roof water yield pattern. The result has considered that the discrepancy between aquifer water-rich zones and structures in the first winning district is quite high, and the zones are presented plate-shaped in distribution, mainly distributed in two major inclined structures and subsided column X7, as well as near subsided columns under the southern surface facilities area. Using the water yield coefficient method and analytic method carried out pit-bottom and first winning working face water inflow prediction, considered-the results from the former method are more reliable. Using the confined aquifer unsteady flow constant drawdown method carried out first winning district No.1302 working face water inflow dynamic prediction, has found that the roof sandstone aquifer is characterized by drainage water filling. The study has guiding significance in water control during Licun eoalmine construction and winning district production, besides, as a main reference in new eoalmine drainage system design and water control measures in western Luan mining area deep coal buried area.
