摘　　要：通过对煤田地质勘探、钻孔揭煤资料的分析,应用瓦斯地质理论和线性回归的分析方法,分析了车集煤矿煤层瓦斯赋存规律,探讨了煤层瓦斯赋存与地质构造、煤层埋藏深度、煤层厚度、岩浆岩侵入、顶底板岩性等地质因素之间的关系,综合分析认为断层、岩浆岩侵入及分布是影响车集煤矿二2煤层瓦斯赋存的主要地质因素。Through the anlysis of coal geological exploration and drilling uncovering coal data,using analytical method of gas geological theories and linear regression,the gas occurrence laws in coal seam of Cheji coal mine are analyzed,and the ralationship between gas occurrence in coal seam and geological factors including geological structure,burial depth of coal seam,coal seam thickness igneous rock intrusion and roof and floor lithologic.Comprehensive analysis show that fault,igneous rock intrusion and distribution are key factors affecting the gas occurrence in coal seam of Cheji coal mine No.22 coal seam.
