Abstract: With the calculation tool of the third theory of quantification, the basic theory of the study of sensitive geology factors of coal and gas outburst was introduced; the transform of the study of geology factors of coal and gas outburst from qualitative to quantitative was realized.The convenience of the forecast, prediction, prevention, and cure of coal and gas outburst was offered. As an example, the sensitive factors of Jiaozuo Zhong-macun coal mine were filtered.The result indicated that close Lizhuang fault,coal fork,and sandstone top board was sensitive geology factor influencing gas outburst of the mine.
