Abstract: In view of the distribution characteristics of ore bodies and aquifers and on-site construc⁃ tion conditions，comprehensive geophysical advanced detection research in rodway can be carried out to ensure safe tunneling and safe mining. Based on the transient electromagnetic method，TSP advanced prediction and borehole geological radar，the advanced detection of roadway is carried out，and the bad geological conditions in front of the face are comprehensively analyzed，and the applicability of each technology is verified. The results show that the comprehensive geophysical prospecting technology can accurately detect the strong water-bearing fault fracture zone and secondary fracture zone or fissure in front of the test roadway face. Transient electromagnetic method and borehole geological radar are sensitive to water. Transient electromagnetic method can determine the position of occurrence，but there is a blind area in the shallow part. TSP advanced prediction has a good effect on the judgment of elastic interface.

Key words: advanced detection, transient electromagnetic method, TSP, borehole radar
