摘　　要：通过对煤田地质勘探、钻孔揭煤资料的分析,应用煤层瓦斯赋存理论和回归分析方法,分析了平煤六矿戊8煤层瓦斯赋存规律,探讨了煤层赋存及瓦斯含量与煤层埋藏深度、底板标高、煤层厚度、顶底板岩性、地质构造等因素的关系。分析结果显示,煤层埋深是影响煤层瓦斯含量的主要因素,断层及煤层顶底板岩性对戊8煤层瓦斯赋存起主控作用。Through the anlysis of coal geological exploration and drilling uncovering coal data, using coal seam gas occurrence laws and regression analysis,the gas occurrence laws in V s coal seam of Pingdingshan No. 6 Coal Mine are analyzed, and the relationship between gas occurrence and content in coal seam and geological factors including burial depth of coal seam, floor elevation, coal seam thickness, roof and floor lithologic, geological structure is discussed. Comprehensive analysis shows that burial depth of coal seam is key factors affecting the gas content, geologic fault and roof and floor lithologic are key factors affecting the gas occurrence of V s coal seam.
