摘　　要：利用瓦斯吸附常数测定仪,对高瓦斯煤样进行了温度及含水量影响吸附甲烷特性的实验研究。研究结果表明:温度与吸附常数a及温度校正系数之间呈负指数关系,与吸附常数b呈正指数变化;煤样含水量与吸附常数a、水分校正系数倒数之间呈一次线性关系,而与吸附常数b之间没有固定的关系式;最后得到煤层瓦斯含量与温度校正系数及水分校正系数之间的关系式。研究结果对于进一步研究煤对甲烷吸附特性、完善间接法测定瓦斯含量具有一定的理论指导意义。Applying methane absorption constant tester,experiment of high methane-content coal＇s temperature and water content influencing methane absorption quality was finished. Results showed that temperature and absorption constant a and temperature correction coefficient took on negative exponent relationship,took on exponent relationship with absorption constant b. Water content and a and reciprocal of moisture correction coefficient took on one linear relationship,and no fix relationship with b. The relational expressions of methane content,temperature correction coefficient and moisture correction coefficient were obtained. Above results had a guiding significance for further researching methane absorption quality and perfecting indirect methane measuring method.
