Abstract: Identifying the hydrogeological conditions,including the distribution of water in the mining face and the surrounding old empty roadways,and delineating the "three zones" for water control are crucial requirements for water control in coal mines.In this study,a transient electromagnetic method center return line device was used to detect local dripping water in the underground roadway of the Huanglong Jurassic coalfield.By encrypting the measuring points,conducting multi-angle detection,three-dimensional inversion resistivity spreading,multi-dimensional imaging analysis,and other technologies,the source,extension,and conduction of the water were traced.The results were combined with geological data to investigate potential hazards to mine safe production.This study provides an efficient and accurate means of investigating the traceability of mine water hazards.
