掘进面冲击地压实时无线监测预警技术

    Rockburst Real-time Wireless Monitoring and Early Warning Technology in Heading Face

    • 摘要: 通过分析掘进面冲击地压危险区域分布特征,提出了以钻孔应力测量代替钻屑量作为掘进面冲击地压监测预警指标;对KJ615掘进面冲击地压实时监测预警系统进行了应用分析,结果表明系统能够实时监测掘进面围岩应力动态变化,实现冲击地压危险区及其危险程度实时连续监测预警;通过在矿山的现场应用试验,表明系统能够准确的预报冲击地压危险区及其危险程度,保障了高冲击地压危险掘进面的作业安全。

       

      Abstract: In view of the rockburst regional distribution of the heading face, the article proposes that taking the stress measurement instead of drilling crumbs as main monitoring indexs. Through field application test of the KJ615 monitoring and early warning system of rockburst, the results show that the system can real-time monitor heading face dynamic changes of surrounding rock stress, and achieve continuously and real-time monitoring and early warning for the rockburst dangerous areas and danger level.By applying this monitoring and early warning system at the heading face in mine, it is proved that the system can forecast dangerous areas and dangerous level accurately, which guarantee operational safety at high risk rockburst heading face.
