Abstract: In order to eliminate the major hidden trouble of water conductive structures for the safe-mining of working face in the complex geological structure of coal mine, according to the field condition, we use the transmission method of channel wave seismic and the transient electromagnetic method to explore the water conductive channels of geological structure in 3307 working face. After that, dealing with the channel wave data and explaining the results through time-frequency method and tomography method, we use 3D slice technique to deal with the data of TEM. Detection results indicate the comprehensive geophysical exploration technique of channel wave seismic method and transient electromagnetic method could explore the water conductive channels of geological structure effectively, which can supply reliable evidences for the water hazard control and prevention of working face.
