Abstract: The channel wave seismic exploration technology has been applied to find out the geological factors of hidden disaster before mining. But at present, there are few researches on the occurrence and characteristics of channel wave in main mining areas of China. So, We establish the numerical models of different surrounding rocks corresponding to different mining areas for forward forward simulation. Then, based on the actual channel wave data of nearly 40 coal mines, the statistical analysis of the data is carried out, and the occurrence and development characteristics of the channel wave are obtained. The results show that the velocity and frequency of the channel wave are similar in the same large area because of the similar strata. The velocity of the channel wave is inversely related to that of the surrounding rock, the higher the surrounding rock velocity, the lower the channel wave velocity. The structural development of the mining area is related to the conditions of the coal seam channel wave conductivity, and in the area with simple structure, the occurrence of channel wave is better. The results can be used as a reference for the interpretation and analysis of practical data.
