Mathematical model describing the process of oxygen transporting in loose coal was derived in the case of considering some simplified conditions, such as ignoring Soret effect, regarding loose coal as isotropous and well proportioned media and so on. 在忽略Soret效应、假定煤体为各向同性的均匀多孔介质等简化条件下,推导出氧气在煤矿井下松散煤体中输运过程的数学模型。
