摘　　要：通过实验对煤的瓦斯放散特性与瓦斯吸附解吸性进行了初步研究,研究发现吸附量及压力与吸附时间均呈现对数函数关系,且有较高的拟合度。通过对吸附解吸实验数据分析计算出瓦斯放散初速度与实验测得值具有较好的吻合性,从而为瓦斯放散初速度测定提供另一种科学有效的途径。Through the experiments to researching the relation between gas emission characteristics and gas adsorption and desorption of coal,It was found that logarithmic relationship between adsorption capacity and adsorption time,pressure and adsorption time too,and has a higher fitting degree.Through analysis of adsorption and desorption experiment data,the initial speed of methane diffusion is calculated.The date and the experimentally measured values are in good agreement.A scientific and effective way is provided for determining the initial speed of methane diffusion.
