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,可达到预测预报冲击矿压危险的目的。
One of the crucial elements influencing the rock burst is the structure of roof rock stratum, especially the flinty and thick sandstone roof over the coal seam. By experimental research, field measurements for electromagnetic emission around the workfaces and the analysis of the rock burst in mining area, it is indicated that the movement and fracture of key roof stratum have great influence on rock burst. Evaluating and forecasting the danger of the rock burst can be achieved according to the rules of the roof movement and determination.
