摘　　要：分析了煤矿巷道掘进过程中接收的电磁辐射信号指标特征,给出了电磁辐射法预测煤与瓦斯突出的敏感指标及临界值的确定方法。该方法有利于电磁辐射预测煤与瓦斯突出技术在煤矿中的推广应用,可以提高煤矿突出危险预测的准确性。The characteristics of the electromagnetic signals detected in tunneling are analyzed. The determination method of the sensitive indexes and the critical value for forecasting coal and gas outbursts by electromagnetic emission is presented out. The method is favorable to the promoted application of the elec- tromagnetic emission technology in forecasting coal and gas outbursts, and can the accuracy of coal and gas outbursts forecast.
