摘要/Abstract

摘要：通过理论分析、现场实测和冲击矿压现象分析，说明了顶板坚硬岩层产生的静压和突然运动、破断均可使煤体内部裂纹不稳定扩展而容易发生冲击矿压.

关键词： 冲击矿压, 坚硬顶板, 裂纹, 失稳扩展

Abstract: By theoretical analysis and actual measurement of field and phenomena analysis of rock burst,the author illustrates the directionless pressure,sudden movement and rupture of hard roof lead to the internal cracks of coal instable development,which easily results in rock burst happening.

Key words: rock burst, hard roof, crack, instable development
