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。
In order to improve the accuracy and reliability of the direct determination of gas content, the cumulative desorption amount of two coal samples from Cuimiao Mine 11 and Pei Gou 32 mining areas at different adsorption equilibrium pressures was tested in the laboratory. Mathematical software statistical analysis of desorption data of two coal samples, the study obtained two coal samples with logarithmic desorption law. Through comparative analysis with Barrell, Sun Chongxu and Wang Youan, it is found that the formula of logarithmic function is superior to other formula of leakage loss, and then the formula of logarithmic function is put forward to calculate the direct method of leakage and its preliminary application in engineering .
