摘要
随着煤矿采掘深度和强度的不断加大,冲击地压灾害愈发严重。冲击地压的发生是能量在煤岩体内部积聚的结果,高应力是冲击地压的充分必要条件。现有冲击地压防治方法都是通过卸围压来释放煤岩体内部积聚的能量,从而减弱煤岩体内部的应力集中,防治冲击地压现象。
With the increase of mining depth and intensity of mines, the hazard of rock burst is more serious. The rock burst is caused by energy accumulation inside coal and rock mass. High stress is necessity and sufficiency of the rock burst. The existing prevention of the rock burst is to release the energy by reducing confining stress and to decrease stress concentration in the coal and rock mass.
