Abstract Due to the problems of coal mining technology in Shuiliandong Mine in Binchang mining area, the distribution of goaf is irregular and there is no detailed hydrogeological data, which seriously threatens the efficient and safe production of the mine. In order to accurately explore the distribution law of coal mine goaf and avoid the occurrence of disasters and accidents, the combination of hole radar, peep in hole, trajectory measurement, radio wave perspective between holes and conventional direct current method exploring depth was used for detection. The boundary of goaf was delineated by geophysical prospecting in hole, and five goafs were delineated by combining the reflection law of direct current method exploring depth on goaf and the exposure of drilling holes, which provided a strong basis for coal mine safety mining.
