Abstract: Abstract First of all, the application mechanism and method of seismic CT technology are introduced. Then the rockburst risk index distribution figures can be gained by computer inversion method based on the field measured data combining with the rock burst tendency of B1+2 at level of +475m in the WuDong coal mine, from which it can show the high rate area of rock burst and the changing process of stress in the coal and rock mass as well as evaluate the effect of prevention measures for the rock burst. The results show that the CT technique of seismic wave can meet the field application requirements with the reliable results.

Key words: Keywords Seismic CT technology, the risk of coal mass burst, rock burst, controlling measure
