AE Method of Evaluating the Danger of Rock Burst

The AE (acoustic emission) of rock is related to its destruction extent under loading action. The variation and lasting time of AE mark the changes of balance and the danger of rock bodies. According to this rule, the danger of rock burst can be evaluated and forecast based on the deviation values of 8 parameters relating to mining activities. The AE method of evaluating and forecasting rock burst was put forward, and has been proved to be reliable and effective in practical application.
