Abstract: In order to master the hydrogeological conditions of the working face and the geological abnormal bodies such as the scouring zone in the working face, Yidong Coal Mine has discussed a set of effective comprehensive geophysical exploration methods for the upper and lower wells of the working face: Before the mining of the working face, the ground transient electromagnetic method is adopted to explore the water abundance of the overburden. At the same time, according to the excavation exposure of the two roadways of the working face, the trough wave, underground transient electromagnetic and radio wave perspective methods are selected to comprehensively detect the working face structure, the abnormal area of the scour zone and the water abundance of the roof overburden. The detection results provide geological guarantee for the safe production of the coal mine and improve the production efficiency.
