摘要针对济三煤矿现场监测数据，通过分析和数值计算，建立钻屑量、支承压力以及钻孔应力的关系，在此基础上，研制冲击地压实时监测预警系统。通过应力测量代替钻屑量作为冲击地压危险性主要监测指标和实时监测工作面前方应力场的变化规律，实现冲击地压危险区及危险程度的实时连续监测预警。自主开发的分析预警软件可以实时显示随工作面推进的支承应力动态云图和测点应力柱状图，设定报警阈值，以判断危险区域及其危险程度，预报发生冲击地压的可能性。通过多个冲击危险矿井的应用，表明该系统能准确地预报冲击危险区及其危险程度，实现高冲击危险工作面的安全开采。

Abstract：By means of analyzing field monitored data and numerical calculation in Jisan mine，the relationships of drilling crumbs，support pressure and drilling stress are established. Based on this，the real-time monitoring and precaution system of rockbursts is developed. By taking the stress measurement instead of drilling crumbs as main monitoring specifications and monitoring the change rules of stress field at the front of the work face，the continuous and real-time monitoring and precaution for the rockburst dangerous areas and danger severity could be implemented by the system. The self-developed precaution analysis software can display bearing stress dynamic contour and monitoring point stress column. Additionally，the dangerous areas and dangerous levels are estimated by setting the warning threshold value. So，the possible occurrence of rockbursts is predicted. By applying this monitoring and precaution system to some rockbursts mines，it is proved that the system can predict the precautions dangerous areas and dangerous levels accurately. In this way，the secure development of dangerous working faces with severe rockbursts can be done.

Key words： mining engineering equivalent drilling rockburst front stress monitoring and precaution
