Underground Engineering Rock Burst Review of Research

Based on the research of rock burst in underground engineering at home and abroad， definition，type, intensity grading，influencing factors，the failure mechanism，the empirical criterion and on-site forecasting and control methods of rock burst are summarized systematically. The current main problems in rock burst research are pointed out and the idea of rock burst comprehensive prediction are put forward. We recommend that the rock burst prediction should be divided into three steps, i.e. tendentiousness prediction，trend prediction and field prediction and forecasting.
