摘　　要：通过对基于电磁辐射的煤岩体损伤参量的分析,阐述了电磁辐射法预测煤矿冲击矿压危险的原理和冲击破坏预测准则,深化了对其的认识.提出了冲击破坏预测准则中电磁辐射临界值的确定方法,并对煤矿冲击矿压危险等级依电磁辐射法进行了划分,提出了相应的防治措施.通过实例介绍了电磁辐射法评定煤矿冲击矿压危险等级的应用情况.Based on analysing the damage parameter of coal and rock on the electromagnetic emission （ EME）, the forecasting principle of rock burst danger and the forecasting guideline of burst failure applying the EME method were expouned. The method determining the critical value of the forecasting guideline of EME was put forward, and rank of the danger of rock burst was divided according to EME. The corresponding control measures was put forward. Finally, assessing the rank of the danger of rock burst applying the EME was introduced by an example.
