Prediction and control of rock burst by evaluating rock mass stress

Based on the geo-dynamic division method, firstly, regional active faults are found out, and tectonic structures of rock mass are divided. Then combined in-situ stress measurement and numerical calculation, regional rock mass stress-state is evaluated. The danger zones of occurring rock burst are determined. The distribution of induced stress around coalface and tunnels is researched by the measurement of induced stress and numeric value simulation. According to the conditions of occurring rock burst, we can determine the disposition manners of excavating and tunneling and places in which rock burst may occur. It can provide the basis for setting down corresponding precautions against rock burst.
