Through a comprehensive analysis of the geological structure of Xingshan coal, gas geological parameters and parameters of gas emission, we re- searched the gas-geology regularity and the major influence factors of No. 27 seam in Xingshan coal mine. Comprehensive analysis shows that mine faults, burial depth, and roof and floor lithol- ogy are the main factors affecting the gas occurrence. The relationship of gas content of 27# coal bed and the coal seam buried depth is closer. Overall, along with the increase of depth of coal seam, gas content increases. Gradient change is that when buried depth increases 100 m, gas content in- creases 2.46 m3/t. Keywords Tectonic Evolution, Gas Occurrence, Fault, Depth # 兴山煤矿27 煤层瓦斯赋存影响因素分析
