Abstract：To explore the influence factors of coal consistent coefficient and get accurate prediction index of coal and gas outburst , experimental factors and natural factors of coal consistent coefficient were analyzed , and then prediction model of coal consistent coefficient and uncontrollable factors was built .The results show that:( 1 ) Coal consistent coefficient is influenced by failure types , metamorphic grade , moisture and ash content of coal.The influence of failure types and metamorphic grade on coal consistent coefficient is realized by chan -ging specific surface area of coal .(2) specific surface area is negatively correlated with consistent coefficient , while moisture and ash content is positively correlated with consistent coefficient .These influence factors are linear correlation with consistent coefficient .(3)Based on the linear correlation between influence factors and consistent coefficient , prediction model is built , and the accuracy of prediction model is verified by using the data of Jiulitai coal mine of Shanxi Coking Coal Group .
