Prediction and prevention technology of rock burst based on stress control theory

The occurrence of rock burst in mine relates to not only the physical and mechanical properties of coal-rock mass itself, but also the stress environment that coal body is in. The prediction, prevention and control of rock burst should focus on the mining induced stress. The mining induced stress monitoring system was used to monitor coal-rock mass stress directly and the micro seismic monitoring system indirectly evaluates the rock burst liability according to the stress change. Technology of blasting for pressure relief, and the stress control theory of rock burst prevention was further applied and good results were achieved.
