Abstract Based on quantitative and qualitative analysis of the gas content and emission in Xinsan Mine,the distribution of gas occurrence was obtained. The linear regression analysis was carried out on the absolute gas emission rate, content and floor level of relevant coal seam, and the absolute gas emission rate and content were predicted. The results showed that the gas content increased with buried depth obviously, it was not very related with fracture, fold, hydrogeological conditions and the roof and floor lithologic.
