摘　　要：煤的孔隙结构与分布是研究瓦斯解吸的基础,不同煤体对甲烷的吸附能力主要受煤体内微观孔隙结构控制。而瓦斯的解吸与吸附是两个相反的过程,与之相似的是不同煤体的瓦斯解吸特征也与其煤体微观孔隙结构密切相关。通过实验对不同破坏类型的煤在不同吸附平衡压力下的吸附-解吸规律进行了研究,得出破坏程度越高的煤体,其吸附-解吸能力也越高,在同样的吸附平衡压力下也可以解吸出更多的瓦斯。The pore structure and distribution of coal are the basis for studying gas desorption,and the adsorption capacity of different coal bodies for methane is mainly controlled by the micro pore structure inside the coal body.The desorption and adsorption of gas are two opposite processes,and similarly,the gas desorption characteristics of different coal bodies are closely related to their microscopic pore structures.The adsorption desorption laws of coal with different types of destruction under different adsorption equilibrium pressures through experiments.It was found that the higher the degree of destruction of coal,the higher its adsorption desorption ability,and more gas can be desorbed under the same adsorption equilibrium pressure.
