    • Abstract
  • In order to identify the structures in the working face 15304 of Xindadi Coal Mine of Yangquan Coal Group in Heshun mining area, the availability of reflection channel wave detection technology was carried out in the side wall of the air return roadway of the adjacent working face 15305 CDM imaging was used to image the structures in the working face. CDM imaging was calculated with channel wave velocity of 1025 m/s, the resulting image shows that there were two strong reflecting interfaces with extension length of more than 500 m inside the working face.The first reflecting interface was the fault DF5 which was exposed in the tunnel engineering, the other was consistent with the extension direction of the concealed fault DF6. The results show that the reflection channel wave detection technology is effective for the exploration of small structures in Heshun mining area, and provides geological basis for the design of working face and roadway development of coal mine.
