Fault is one of the main water inrush channels of coal seam roof water damage during coal mining.Before coal mining,the distribution of structures in the working face should be investigated.Therefore,channel wave seismic exploration has become an important technical means for pre-mining structural exploration in coal mines.The 4102 working face of Wenjiapo Coal Mine in Binchang Mining Area is located on the east side of Panel 41 of the coal mine,and is the second mining face of Panel 41.According to the actual geological data revealed during tunnel excavation,the faults in this working face are relatively developed,which may affect the normal mining of the working face.The length of the fault extending into the working face is currently unclear.Therefore,the slot wave transmission method was used to detect the development of faults in the mine working face of Binchang mining area.The results shows that the method is effective,and the basic exten-sion of the four faults developed in the working face is identified,providing a certain scientific basis for the prevention and control of water disasters in coal mines.
