摘　　要：为进一步研究具体矿井的煤层瓦斯富集影响指标,基于煤矿瓦斯赋存普遍性规律,以某矿低渗透煤层为研究对象,根据该矿实际勘探资料采用层次分析法对影响煤层瓦斯含量的主要因素进行分析,发现地质构造是影响该矿瓦斯富集程度的主控因素;应用线性回归方式进一步细化分析煤层瓦斯含量与断层参数的关系,揭示断层是该矿瓦斯富集的主要敏感指标,并确定指标判据,为具体矿井实际预测瓦斯含量提供重要保障。In order to further study the influence index of coal seam gas enrichment in specific mines on the basis of the general law of coal mine gas occurrence,the low permeability coal seam of a specific mine was taken as the research object.According to the actual exploration data of the mine,the main factors affecting coal seam gas content were analyzed by analytic hierarchy process.It is found that geological structure is the main factor affecting the gas enrichment degree of the mine.The relationship between coal seam gas content and fault parameters was further analyzed by linear regression method.It is revealed that fault is the main sen⁃sitive index of gas enrichment in this mine,and the index criterion was studied and determined,which pro⁃vided an important guarantee for the actual prediction of gas content in specific mines.
