Abstract In this paper, transient electromagnetic method was used to explore the upper burned area (No.4-2 upper coal seam) on the No.50106 face of Hejiata Mine. The collected data were processed, and the apparent resistivity profile and the apparent resistivity plane were plotted. Combined with the existing hydrogeological data, the results were analyzed. Finally, seven anomaly watery zone were delineated in the detection area, which provided a basis for the water damage prevention and control and safe production in coal mines.
