| Abstract: | On the basis of determining principle of critical value on coal and gas outburst forecasting index,influence factors and their changing laws of forecasting danger of coal and gas outburst by way of electromagnetic emission(EME) in working face were observed,a comprehensive judging method of critical value on coal and gas outburst forecasting index was put foreard and applied the method to Hongling coal mine of Shenyang mining group.The application results indicate the method has many characteristics,such as simple and convenient,accurate and reliable.Itsupplies a new thinking and method for determining critical value on coal and gas outburst EME forecasting index. |

| Keywords: | Coal and gas outburst Electromagnetic emission Critical value Comprehensive judging method Forecasting index |
