The geological conditions in Yunjialing mining area were relatively complex. In order to correctly guide the design, advancing and recovery mining of working face and reduce the coal resource waste and roadway engineering caused by unclear geological structure, based on this problem, seismic CT detection research was carried out in the Yunjialing mining area, and on the basis of two working face seismic CT imaging analysis experiments, numerical model simulation, indoor physical simulation experiments and other methods were applied to study the coal-bearing strata of the mining area. The elastic attribute parameters and geological structure were analyzed, studied and verified, and the seismic CT wave velocity parameters and effective interpretation methods suitable for the geological conditions of the mining area were summarized. The results of mining verification of 5 working faces showed that the CT detection method and selected parameters of the working surface were scientific and reasonable, and the detection results were reliable.
