摘要
顶板岩层结构,特别是煤层上方坚硬厚层砂岩顶板是影响冲击矿压发生的主要因素之一。通过实验研究、现场实测、冲击矿压现象分析,说明了顶板坚硬岩层,特别是顶板的关键层运动、破断对冲击矿压的发生有巨大的影响。掌握顶板的运动规律,并对其进行监测。
Roof structure, especially hard and thick sandstone roof, is one of the main factors lead to the occurrence of rock burst. By laboratory study, field test and phenomena analysis of rock burst, the paper indicates that the hard strata of roof especially the moving or breaking of the key strata or stratum has great influence on the occurrence of rock burst. Its forecast can be realized by the understanding of roof movement and constantly monitoring
