摘要
由于采空区陷落岩石构成的气体孔隙渗流介质空间是极度复杂和不规则的，并且目前还不存在可行的手段对采空区内部状态进行观测。利用传统的数学物理方程描述的渗流问题的精确解与采空区岩石陷落形成严重不规则介质空间的现实是不相符的。本文提出了采场气体渗流的模糊微分方程，给出了模糊渗透性系数和非均匀孔隙介质采场气体稳定渗流的模糊解概念。
Because the gas porosity permeating flow medium space ,which is caused by the subside of the rock in goaf ,is very complicated and irregular ,and now there is no feasible means that can observe the internal state of goaf. So the accurate solution of the permeating flow problem ,which is described by traditional partial differential equation ,does not match the fact that the irregular medium space is caused by the subside of the rock in goaf. The paper puts forward the fuzzy differential equation of the permeate flow of the gas in stope, gives the concept of fuzzy permeate coefficient ,and gives the fuzzy solution concept of the stable permeating flow of the irregular porosity medium stope gas.
