Abstract：In order to improve the accuracy of underground transient electromagnetic water damage detection and reduce the influence of the metal and charged body in the underground roadway on the detection results during the detection process, through physical simulation, numerical simulation and other technical means, the acquisition and observation system of transient electromagnetic measurement was optimized, and the quality of detected electromagnetic data was evaluated. Combined with the processing and correction of transient electromagnetic data forward and inverse algorithm software, the interpretation accuracy of water-bearing abnormal body in coal mine was improved, and the hidden water-bearing structure in front or side of excavation was predicted in time, which provided a strong technical guarantee for safe excavation of coal mine.
