摘要
为准确测定新景矿各煤层瓦斯气体来源,利用同位素测定技术,现场取样后测定并分析了各煤层微量元素和有机碳同位素的含量及分布特征,以此对各煤层地点的混合气体碳同位素值建立了模型,并根据实测碳同位素值计算出各煤层瓦斯气体在混合气体中所占的比例,分析了矿井瓦斯气体来源比例的变化特征。
In order to accurately determine the gas source of each coal seam in Xinjing Mine,the content and distribution characteristics of trace elements and organic carbon isotopes in each coal seam are measured and analyzed by using isotope determination technology after field sampling,so as to establish a model for the carbon isotope value of mixed gas in each coal seam.According to the measured carbon isotope values,the proportion of gas in each coal seam in the mixed gas is calculated,and the variation characteristics of the source proportion of mine gas are analyzed.
