Abstract：In order to effectively detect coal thickness,structure,goaf,and then guide the coalmine safety with high-efficient production,SUMMIT-Ⅱ EX channel wave seismograph is used in Yima Coal Group.Transmission method is applied to detect the coal thickness.Based on the negative relations between the wave velocity and the coal seam thickness,the quantitative interpretation of the coal thickness is realized and the prediction accuracy reaching 86％.Reflection method is applied to detect the strike fault with the reflect of channel wave when it meet wave impedance interface such as fault during traveling along the coal seam.According to the channel wave propagation velocity and the reflection time of arrival in detector,the fault location is calculated and predicted.The actual deviation is less than 5 m.Meanwhile,the seismograph has been tentatively applied to detect gas zone,the risk area of rock burst and water inrush.The preliminary valuable results are achieved.The channel wave detection technology is an effective method of mine geophysical exploration and has a good prospect.
