摘　　要：简述了电磁辐射法预测岩爆的原理,实测给出了有岩爆危险时电磁辐射强度和脉冲数的临界值和有岩爆危险时电磁辐射的变化规律。结果表明,采用电磁辐射法预测岩爆是可行的,并且实施需要时间短,准确率高,能够监测到工作面前方的岩体活动情况,是一种很有发展前途的岩爆危险性预测预报方法。The principle of monitoring rock burst with the Electromagnetic Emission（EME） method is described. According to measured results, the critical value of the intensity and pulse number of EME when the danger of rock burst could occur is determined, and a variety law of EME is obtained. The results show that monitoring rock burst with this method is feasible and takes a short time, the accuracy of forecasted results is great. In addition ,EME method can monitor the behaviour of rock mass in front of the face. So, EME method is a promising one for monitoring rock burst.
