| 摘 要： | 为了提高瓦斯含量直接测定法的准确性、可靠性,在实验室测试了崔庙煤矿11采区、裴沟32采区2个煤样在不同吸附平衡压力下不同时间段的累计解吸量,运用数学软件统计分析2个煤样的解吸数据,研究得出了2个煤样具有对数解吸规律。通过和巴雷尔、孙重旭、王佑安公式对比分析后发现对数函数公式优于其它漏损量推算公式,据此提出了对数函数公式用于直接法漏损量的推算及其工程应用初步建议。

| Abstract: | In order to advance the accuracy and the reliability of direct determination gas content,researchers tested desorption of the two coal samples in laboratory which were from No.11 mining area of Cuimiao and No.32 mining area of Peiguo.Desorption law is statistically analyzed by related mathematical software and then the two coal sample desorption laws are drawn out.It is found that the logarithmic function is better than other leakage calculation formulas by comparison research on Barrer,Sunchongxu and Wangyouan.Logarithmic function and some suggestion are proposed to use in the loss quantity calculation of direct determination gas content in engineering. |
