【摘要】 针对宽沟煤矿发生的冲击地压,基于现场监测数据和数值模拟结果,对现场出现的多个冲击地压案例进行了分析,得出了宽沟煤矿存在两种典型的冲击地压类型:工作面坚硬顶板悬顶型冲击地压和巷道应力叠加型冲击地压。对不同类型冲击地压,采取了有针对性的防治措施。现场应用表明,冲击地压防治效果良好。更多还原

【Abstract】 Aiming at the rock burst occurrences at Kuangou coalmine, analyzing the multiple rock burst cas-es appear on the on-site, which based on the on-site monitoring data and numerical simulation results. Itconcluded that two typical types of rock burst existed in Kuangou coalmine: working face tight roof suspen-sion type rock burst and roadway stress superposition type rock burst. For different types of rock burst, tar-geted prevention and control measures are adopted. Field application shows that the control effect of rockburst is good.更多还原
