Abstract：The hazard degree and undetectable degree of the old goaf area with detailed information known by the mine were generally small, but it would inevitably affect the geological and hydrogeological conditions of the adjacent unmined working face. The comprehensive geophysical exploration method referred to the construction and interpretation method combining transient electromagnetic, amplitude frequency electrical perspective, electric depth-measurement, radio wave tunnel perspective and other technologies. In this paper, by comparing and analyzing the geophysical exploration results of No.9302 Face and No.9118 Face in Xipang Mine before mining, it was determined that it had practical significance for geophysical exploration construction and mine safety production.
