Abstract Due to the complex and changeable geological conditions of the mine and the non-exclusion of objective interference factors in the construction process, the problems of high false alarm rate and low accuracy of geophysical detection results are caused. Especially for the detection of relatively complex geological structures, it is difficult to achieve good detection results by single geophysical detection technology. In order to effectively solve this problem, it is necessary to use comprehensive geophysical detection technology to carry out accurate geophysical detection and transparent geology work. In this paper, the No.1-105 face of Yilong Coal Industry of Huozhou Coal and Electricity Group was taken as an example. Radio wave tunnel perspective, transient electromagnetism, audio electrical perspective and direct current method exploring depth were carried out in this working face, and the comprehensive results of four geophysical detection methods were analyzed and studied. It showed that the combined analysis and interpretation of underground multi-means comprehensive geophysical detection could effectively improve the accuracy of structure and water damage prediction and improve the accuracy of detection.
