摘要
冲击地压危险状态可通过分析岩体内的应力、岩体特性、煤层特征等地质因素和开采技术因素来确定。冲击地压危险性指数是根据已发生的冲击矿压事故来确定的。实践证明 ,这种方法对圈定区域性冲击危险程度 。
The danger state of rock burst has been evaluated by the factors of geology and mining technology in such way that analysis stress, rock burst characteristics and mining layers in the rock mass. The summary method for evaluated danger has been established based on the accidents which happened. It is proved that this method is very effective for us to define the regional danger degree, to design mining procedure and to defend the rock burst.
