Research of regression analysis of coal and gas outburst risk and gas emission characteristic value on mining face

Relationship of coal and gas outburst risk and gas emission characteristic value on mining face was analyzed. Through taking the average and maximum amount of gas emission and data slope of gas concentration of fallen coal as gas emission characteristic value, a regression analysis method of coal and gas outburst risk and gas emission characteristics value on mining face was proposed combining with coal and gas outburst risk indicators. The application of examples shows validity of the method.
