摘要
千秋煤矿是一个冲击地压灾害严重的矿井,其上覆巨厚砾岩层破断失稳对冲击地压的发生有着很重要的影响。本文通过相似模拟试验和理论分析,着重研究上覆巨厚砾岩层破断失稳诱发的重力型冲击地压机理,并对上覆离层垮落砾岩层诱发的冲击载荷进行估算。研究结论与现场实测吻合的很好,并针对该类冲击地压提出了监测与预防相结合的防控思路。
Qianqiu Coal Mine is a rockburst hazard coal mine, and it has great influence on occurrence of rock burst on overlying thick conglomerate layer. This article is aimed at gravity rock burst mechanism of it caused by instability situation through similar simulation experiments and theoretical analysis, and do some impact load calculation on it. There is a close correlation between conclusions and field measurement, and it proposed combination of prevention and control of monitoring and prevention idea.
