摘要
对抽放巷道煤壁瓦斯渗流规律进行了研究 ,运用达西定律 (DarcyLaw)、朗格缪尔方程 (LangmuirEquation)、理想气体状态方程以及气体流动的连续性方程 ,建立了煤层瓦斯单向渗流的动力学模型 ,通过对动力学模型的求解 ,推导出煤壁瓦斯渗流速度的表达式。
This paper studies on the principle of gas seepage in the wall of drainage roadway.On the base of Darcy Law,Langmuir Equation ,the equations of the gas flow continuity and state,a dynamics model of gas seepage in the seam is founded.By solving the model,the calculating formula of the velocity of gas seepage in the wall is worked out.
