依据煤矿钻屑瓦斯解吸指标K1值的测定原理,对山西晋城大宁煤矿3#煤层的6个煤样进行了K1与瓦斯压力p关系的测定,结合实测煤样的工业分析参数,研究了钻屑瓦斯解吸指标K1随煤层瓦斯含量W的变化特性,结果表明:钻屑瓦斯解吸指标K1与煤层瓦斯含量W之间有显著的相关性,两者之间呈现很好的指数函数关系,且在瓦斯含量低值区两者符合线性关系。 According to the determination principle of methane desorption index K1 in coal mine, the relationship between K1 and gas pressure p of 6 coal samples in No.3 coal seam of Daning Coal Mine in Jincheng City, Shanxi Province was measured. Combined with the industrial analysis parameters of the measured coal samples, The results show that there is a significant correlation between the gas desorption index K1 of drilling gas and the gas content W of the coal seams, showing a good exponential function between the two, The gas content in the low value area is in line with the linear relationship.
