| 摘 要： | 利用煤岩破坏力电耦合模型、煤与瓦斯突出和冲击矿压发生的不同特点及现场测试的大量数据，得到了两种灾害的电磁辐射预警临界值系数和动态变化趋势系数的确定方法.研究表明:煤岩动力灾害电磁辐射预警可以采用脉冲数和强度两个指标同静态临界值和动态趋势相结合的方法进行预警，电磁辐射可以将动力灾害危险分为无危险、弱危险和强危险的3级预警方案，对不同的预警级别可以采用对应的防治措施.

| Abstract: | The determined method of the critical values and dynamic trend coefficient of electromagnetic emission(EME) forecasting coal and gas outburst and rock burst was attained according to stress-electricity coupling model of coal or rock,different characteristics of both disasters and lots of data measuring in situ.The results show that EME forecasting indexes were both pulse number and intensity and forecasting method was combination of static critical values method and dynamic trend method.According to this prediction method the danger of dynamical disasters can be classified to three levels forecasting such as no danger,weak danger and strong danger.The corresponding measurements can be adopted to the basis of different forecasting level. |
