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。 Experiments were carried out to study the coal gas emission characteristics and gas adsorption and desorption properties. It was found that there was a logarithmic function relationship between adsorption capacity and pressure and adsorption time, and a higher fitting degree. By analyzing the experimental data of adsorption and desorption, it is calculated that the initial gas velocity is in good agreement with the experimental value, which provides another scientific and effective method for the determination of initial gas velocity.
