Abstract: The seismic wave passive tomographic inversion technology for rock burst dynamic warning is studied and implemented, and the prediction indexes and warning system are developed. By this technology, we can achieve the dynamic warning for rock burst in mining area. At the same time, the treatment schemes and parameters for rock burst danger can be modified and adjusted dynamically, which realizes the active control for rock burst. This system is successfully used in Zhangxiaolou Coal Mine in Xuzhou, which guarantees safety mining of work faces in coal pillar zones.
