基于前期的实验研究成果，得出考虑吸附作用影响的瓦斯渗流方程，在此基础上，建立了钻孔稳定流动状态下的瓦斯渗流模型，并采用数学物理的方法推导出钻孔单向稳定流状态下的解析解，获得了基于考虑吸附作用影响的含瓦斯煤渗透特性分析方法，为研究钻孔瓦斯涌出规律提供了技术支撑。%A gas seepage equation with considering the adsorption effect was obtained according to the earlier experimental results, on this basis a gas seepage model under stable hole flow state was established, the analytical solution under the condition of the hole unidirectional stable flow was derived by the method of mathematical physics, and based on considering the adsorption effect, the analysis method for the permeability characteristics of gas-filled coal was obtained, all of these provided technical support for the research on gas emission law of boreholes.
