【摘要】 在对我国冲击地压分布状况进行研究的基础上,将冲击地压分为煤体压缩型、顶板断裂型和断层错动型等三种基本类型,并分别研究其发生机理,提出了通过煤层注水、卸压爆破、机械振动致生岩体裂隙改变煤体性质防治煤体压缩型冲击地压,通过开采解放层、本层煤解放的高压水射流钻孔割缝、留设煤柱改变顶板运动规律防治顶板断裂型冲击地压,通过限制断层移动防治断层错动型冲击地压等有针对性的治理措施。更多还原

【Abstract】 Based on the study of rockburst distribution in China,the rockbursts are classified to the coalmass compressible type,roof crack type and fault dislocation type. The mechanism of every rockburst type is studied respectively. Based on these study,the effective measures preventing rockbursts are put forward. The measures preventing rockburst of coalmass compressible type are to change properties of coalmass by coal seam effusion,unloading by exploding,mechanical vibration for rockmass crack and so on. The measures preventing rockburst of roof crack type are to change roof movement rules by mining liberation layer,high-pressured water-jet cutting for liberating coal seam itself,pillar remaining and so on. The measure preventing rockburst of fault crack type is to confine fault movement.更多还原
