摘　　要：刘东煤矿位于淮北煤田西北部，煤系地层被新生界地层覆盖，松散覆盖层厚度80～150 m，可采煤层埋深范围大，滑脱构造发育，地层结构极其复杂，三维地震对该区构造控制也不十分充分。利用可控源音频大地电磁法进行面积性勘探，可对矿区内地层结构分布特征、构造发育情况以及煤层顶底板富水性进行定性分析。在此基础上，结合已知地质情况可对矿区水文地质条件做相关评价，从而对煤矿开采工作给予指导性建议。Liudong Coal Mine is located in the northwest of Huaibei coalfield.Coal-bearing strata are covered by cenozoic stratigraphic, and the overburden thickness is about 80~150 m.Detachment structures are developed,and the stratum structure is extremely complex, the method of CSAMT can be used to analyze structure formation,development of structures,hydrous of coal seam.Combined with the known geological conditions,evaluations of the mine hydro-geological conditions can be related,so it can make a specific recommenda-tion for coal production.
