摘要
煤层瓦斯吸附解吸实验经常采用煤样粒度.为了解煤样粒度对煤层瓦斯解吸效果的影响,通过等温吸附解吸实验的高压容量法对不同煤样柱度吸附解吸数据进行测定,并对实验数据拟合分析,结果表明,燥样粒度大于0.25mm对煤层瓦斯解吸影响基本可以忽略,煤样粒度选择0.25 ～ 0.5mm左右时,既能保证实验的准确性又能节省实验时间.
Experiments of coal gas adsorption and desorption often use coal sample size. In order to know the influence of the coal sample size on the desorption of coal gas, a test was made on the data of adsorption and desorption of different size of coal sample by applying high pressure volumetric method of the isothermal adsorption and desorption experiment, and then the data were analyzed. The results show that when the coal sample size is bigger than 0.25ram, the effect on gas desorption can be ignored. When the coal sample size is 0.25 - 0.5mm, it can not only ensure the accuracy of the experiment, but also save the experiment time.
