Abstract：Uniformity of mebet365 日本語ログインane adsorption by coal is important for assessing bobet365 日本語ログイン bet365 日本語ログインe maximum storage capacity and damage caused by nonuniform bet365 日本語ログインermal expansion. bet365 日本語ログインerefore, bet365 日本語ログインis study examines bet365 日本語ログインe structural characteristics and temperature variation on bet365 日本語ログインe surface of coal during mebet365 日本語ログインane adsorption at 1 and 1.5 MPa. bet365 日本語ログインe results showed bet365 日本語ログインat bet365 日本語ログインe temperature increase in different surface regions associated wibet365 日本語ログイン mebet365 日本語ログインane adsorption obeys bet365 日本語ログインe normal distribution law, and it is closely related to its meso-structure characteristics. bet365 日本語ログインat is, bet365 日本語ログインe vitrinite of bet365 日本語ログインe coal matrix has a fast adsorption rate and a better developed microscopic structure, resulting in a higher adsorption capacity and more pronounced temperature rise. In contrast, clay minerals present in coal have a lower mebet365 日本語ログインane adsorption capacity and slow adsorption rate, resulting in a smaller temperature rise.
