摘　　要：以寺家庄矿井工作面为工程背景,采用现场物探、理论分析的方法分析该工作面顶板上覆含水层水赋存规律。其中,煤层低阻异常区6个,A1,A2,A3异常区面积较大,尤以A1异常区北部视电阻率最低,富水性最强;由视电阻率断面图看出,灰岩岩层整体赋水性中等,工作面回采时煤层顶板裂隙发育,容易形成明显的顶板淋水。Based on the engineering background of the working face of Sijiazhuang Mine,this paper analyzed the occurrence law of aquifer water on the roof of the face by the method of field geophysical and theoretical analysis.Among them,there are 6 low resistivity anomaly areas of coal seams,and the area of A1,A2 and A3 anomaly areas is large,especially in the north of A1 ano-maly area,the apparent resistivity is the lowest and the water yield is the strongest;according to the section diagram of apparent resistivity,the overall water bearing capacity of limestone strata is medium,and the roof cracks are developed during the mining of working face,which is easy to form obvious roof drenching.
