摘要
岩石的声发射与岩石在载荷作用下的破坏程度有关，声发射的较大变化和持续时间长说明了岩体平衡状态的变化和危险性的变化——危险性增加或降低．根据此原理可对冲击矿压危险性进行评价和预报．冲击矿压危险性评价及预报指标可选用８个与开采有关的参数，根据这些参数的偏差值，来预报冲击矿压的危险，进而提出了冲击矿压危险性评价及预报的地音法．实践证明，这种方法可靠、有效．
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.
