摘　　要：借鉴石油天然气在孔隙裂隙二重介质中的渗流理论,依据相关的实验研究,结合煤层瓦斯流动的特点,建立了煤层瓦斯扩散与渗流的物理数学模型,并分析了其特点及今后的研究方向。establishes the physical and mathematical model of gas diffusion and permeation in coal seams,using the oil and natural gas permeation theory in material of pores and fissuers for reference,according to the relerant experimental study,inte-gating it self with the gas flow in coal seams,and analyzes it's character and the direction of study in the future.
