深井综放工作面低应力开采防治冲击地压工程实践

Engineering practice of low pressure mining in prevention of rock burst in fully mechanized caving face of deep shaft

该文基于冲击地压实时监测预警系统,提出"低应力"开采防治冲击地压的理念,通过降低工作面冲击地压监测预警系统阈值,提高煤体应力危险级别,提前采取卸压保护,避免黄色预警、杜绝红色预警。工程实践表明该方法可提前预警并处理冲击危险区,现场应用效果较好,为深井综放工作面冲击地压防治提供了一种新思路。

This paper based on the impact of real-time pressure monitoring and warning system, mentioned concept of low –stress mining rock burst prevention, by reducing the pressure to face the impact of monitoring and warning system thresholds, improve stress dangerous levels of coal in advance to take the pressure relief protection against yellow warning, put an end to red alert. Engineering practice shows that the method can advance warning and deal with the impact of danger zones, site application effect better, provides a new idea for fully mechanized caving face rock burst prevention in deep shaft.
