摘要
本文以菲克定律为基础,考虑到受采动应力影响的煤层变渗透性,建立了煤层瓦斯流动的数学模型,探讨其数值解,并通过实测结果说明该数学模型是可行的。
Based on Frick Law and taking into accout the altering osmotic coefficient due to mining stresses, a mathematic model of methane flow from coal walls is proposed, aod its mathematic solution through computer simulation is discussed. The model is proved by measurements on the spot to be plausible
