摘　　要：为确定适用于谢桥煤矿的瓦斯来源分析方法,混合气体现场取样129个,运用五端分源计算模型计算,得到瓦斯来源占比;并以11416和21216工作面为主要研究对象,分别进行传统分源预测和碳氢同位素分源预测,并对预测结果做对比分析。对比分析表明:碳氢同位素分源预测法所反映的采掘工作面瓦斯来源动态演化过程更加全面,更加具有科学性和可靠性,更适用于谢桥煤矿复杂地质条件下的瓦斯来源分析,对类似矿井瓦斯综合治理具有借鉴意义。In order to set up an analysis method of gas origin suitable for Xieqiao Mine,there were 129 mixed gas samples collected in the mine site.With the calculation by calculation model of the source separation at five terminals,the percentages of the gas origins were obtained.Taking No.11416 and No.21216 coal mining faces as the main study objects,the conventional source separation prediction and the hydrocarbon isotope source separation prediction were conducted separately and the comparison analysis was conducted on the predicted results.The comparison analysis showed that the hydrocarbon isotope source separation prediction method could more fully reflect the dynamic evolution processing of the gas origin from the coal mining and excavation faces and would have the science and reliability.The prediction method could be more suitable for the gas origin source analysis under the complicated geological conditions in Xieqiao Mine and would have the reference significances to the comprehensive gas control in the similar coal mines.
