Abstract: In order to study the rock burst occurring in Sanhejian Coal Mine and detect large-scale stress state of working face, the stress field inversion was carried out by shock wave CT exploration technology to establish technical indexes and predict rock burst hazard area. The results indicate that seismic wave velocity is positively related with stress, and the working face of No.9 coal seam near uphill coal pillar of No.7 coal seam is located in high wave velocity and high velocity gradient anomaly area, which basically tallies with " 1.30 " rock burst zone. Large-scale stress of coal and rock mass can be detected and rock burst hazard area can be distinguished by shock wave CT technique so as to take measures for pressure relief.
