There are many geological factors that affect the safety production in coal seam workface. The geological anomalies characteristic can be explained according to the velocity distribution of coal seam revealed by the tomography techniques. By building working face test model, using model tests to establish the system contents such as CT detection technology methods of seismic waves, observing system layout, data acquisition parameters, data processing and geological interpretation. The practical results of the site exploration project shows that the CT imaging accuracy and resolution of the seismic waves can meet the on-site production and technical requirements. And the geological anomalies body in the mine workface can be tested and distinguished effectively.
