Abstract: Based on the comprehensive analysis of influence factors on gas emission,a relationship between the gas emission from coal faces and the influence factors was discussed.By the stepwise regression analysis method,a mathematical model for predicting the gas emission from coal faces was constructed and applied to the prediction of gas emission at the Ⅵ-24110 coal face in the No.10 Coal Mine of Pingdingshan Tian'an Coal Mining Corp.Ltd.The results showed that the model for predicting gas emission was relatively accurate.
