本文通过声发射监测系统对突出危险工作面进行的实时监测研究，提出了可利用声发射信号相对变化率NE作为突出危险判定指标。
In this paper, the real-time monitoring research on the prominent dangerous working face by the acoustic emission monitoring system is proposed, and the relative change rate of the acoustic emission signal can be used as an index to highlight the danger.
