【摘要】 通过不同温度条件下煤与瓦斯吸附、解吸实验,研究了煤与瓦斯吸附、解吸的微观机理,重点分析了高压注水对煤体瓦斯吸附、解吸的影响规律。利用具有压力控制单元和温度控制单元的煤样吸附解吸实验系统,测定煤样在不同温度下瓦斯的解吸量,通过吸附压力降低曲线计算出了吸附速率。更多还原

【Abstract】 Based on the experiments of gasadsorption and desorption of coal samples at different temperatures,the microcosmic mechanism of gas adsorption and desorption of coal was researched and the effect of high-pressure water injection on gas adsorption and desorption of coal mass was analyzed as an emphasis.The gas desorption amounts of coal samples at different temperatures were measured and the adsorption rates were calculated via the adsorption pressure decrease curve,using adsorption and desorption system with pressure and temperature control units.更多还原
