摘　　要：以槽波形成机理及传播规律为基础,进行透射槽波能量分析,探讨了槽波衰减规律,并得出槽波透射与断层断距的关系。在透射能量能穿透工作面的基础之上,采用透射槽波能量层析成像方法对工作面煤层进行成像,得出工作面槽波能量成像构造解释图;根据槽波在煤层中传播的槽波频率变化规律,得到煤层厚度的变化平面图。结果与实际地质资料吻合较好。Based on the in-seam wave formation mechanism and its spread rule, analyze the energy of transmission in-seam waves, and the relationship between in-seam wave transmission and fault displacement was put forward. Get the image of work-face coal by using energy tomography, on condition that in-seam waves can pass work-face. Based on the relationship between frequency and coal thickness, the plan of thickness was obtained. The predicting results are in good agreement with the actual situation.
