【摘要】分析了原岩应力和采动应力对冲击矿压发生的影响,通过采用采动应力监测系统直接监测煤岩体的应力和采用微震监测系统间接监测煤岩体应力的方法,分析了采动引起的应力变化,进而对监测区域内煤岩体的冲击危险性进行了评价;通过对具有冲击危险性的煤岩层实施煤层卸载爆破、深孔断顶爆破和深孔断底爆破技术,进一步验证了冲击矿压防治的应力控制理论,取得了良好的实践效果。更多还原

【Abstract】 Analyzing influence of geo-stress and mining stress on rock-burst,applying mining stress monitoring system and micro-seismic monitoring system to monitoring direct and indirect stress,mining stress variation was analyzed and rock-burst danger of coal and rock body in monitoring area was evaluated.Applying technology of coal blasting for pressure relief,deep blasting for roof and floor broken,stress control theory of preventing rock-burst was proved further and good practicable effect made.更多还原
