No.9103 detection roadway in the west well of Xingtai Mine is the No.9 coal excavating roadway. According to the existing hydrogeological data and comprehensive analysis of No.9100 mining area, the hydrogeological conditions of the working face are clear and the fault structure is developed. Quaternary bottom gravel water, Benxi limestone water and Ordovician limestone water are the water filling sources of No.9 coal floor in No.9103 Face. The transient electromagnetic advanced detection position was located in the opening of the roadway, with seven angles detected in the horizontal direction and seven angles detected in the vertical direction. According to the detection results, there was a relatively low-resistance area in the detection range. It was verified by the mine drilling that the abnormal area was true and reliable.
