摘　　要：瓦斯流动方程是煤层瓦斯流动理论的基石,它反映了煤层内瓦斯流动的机理。本文在达西定律基础上,修正了一类煤层瓦斯流动方程。The gas flow equation,which can objectively describe the correctness or not of themechanism for methane gas flow in coal seams,is the cornerstone for the theory for gas flow in coalseams.Based on Darcy's law,one kind of the equation for gas flow in coal seams has been correctedand reestablished in this paper.
