摘要
根据多孔介质中饱和流动的微分方程和两平行板间窄缝隙内粘性液体流动的微分方程之间存在的相似性，利用缝隙模型，研究了采场气体流动规律并通过模型试验，提出了矿井在无煤柱开采过程中采空区瓦斯的流动方向问题。
This paper is based on the similarity of differential equation between saturated flowing in porous media and viscous flowing in milro fissures between two parallel panels.It studied the regularity of air flowing in stope by fissures model.Through tests,it displayed the problem of the gas flowing direction in the goaf in the no coal column extraction
