Taking the Zhongmacun mine as an example, the geological factors affecting coal and gas outburst were researched. Eight sensitive factors for the outburst of coal and gas were screened out from 11 geological factors using the method of unit classification and the third theory of quantification. The results show that it is feasible to apply the third theory of quantification to gas geology, which offers a new thought to select the sensitive geological factors of gas outburst forecast.]]>Dong, W.Q. and L.X.
