Abstract The geological conditions of Kaiyuan Mining were complex, and the geological structure had a great influence on the mining of the working face. The development of faults and collapse columns in the mine field was the main geological factor affecting the production of the mine, which destroyed the integrity of the minable coal seam and reduced the reserves of coal resources. In production, the exploration of geological structures should be strengthened. In view of this situation, this paper took Kaiyuan Mine as the research object, explored the No.9101 Face and No.9403 Face by means of radio wave tunnel perspective and in-seam wave seism, and delineated the abnormal area. According to the subsequent mining situation of the working face, it could be concluded that the delineated abnormal area was basically consistent with the geological structures such as the actually exposed faults and collapse columns, indicating that the geological geophysical exploration work guided the layout and mining of the working face in time and provided technical support for the safe production of the mine.
