中文摘要：
运用Langmuir单分子层吸附理论，分析了煤对甲烷吸附能力受其含水量的影响。利用WY-98B型瓦斯常数测定仪，分别对2种煤样在不同含水量时吸附甲烷气体的等温吸附曲线、Langmuir压力、吸附常数a，b进行了定性与定量分析，得出了煤对甲烷吸附量随压力的变化关系式及Langmuir吸附常数a，b随煤样内水含量变化的关系式。研究结果表明：含水煤样依然满足Langmuir单分子层吸附理论，吸附常数a，b与煤样中含水量的变化之间存在着一定相关性。
英文摘要：
Adopting the Langmuir monolayer theory for methane adsorption of coal, the effects of moisples with qualitative and quantitative at different moistures. The equation for pressure effects on adsorption quantity was gained and the equation for moisture effects on adsorption constants a and b was gained too. The result of experiment shows that containing moisture coal sample fit the Langmuir adsorption equation and adsorption constants a and b and change of water content in coal samples have correlation.
