摘要
在利用非均匀孔隙介质稳定流动微分方程来揭示采场气体流动状态中,孔隙介质渗透性系数的估计是非常困难的,并且精确的估计也是无意义的。提出模糊渗透系数和模糊限定微分方程的概念,建立了模糊渗流方程,并利用模糊结构元的方法得到了模糊渗流方程的近似解法。利用模糊渗流问题的求解,可以相应得到采空区内影响自然发火的各种因素区域,这为利用模糊预测技术预测采空区自然发火趋势与位置提供了非常有用的分析工具。
Applying the differential equation of steady flow of non-uniform pore medium to disclose the flowage of stope gas, it is very difficult to estimate the penetrability coefficient of pore medium, and it is insignificant to estimate accurately. The concepts of the fuzzy penetrability coefficient and the fuzzy qualified differential equation are put forward The problem of the fuzzy gas permeating flow on stope may be prescribed by a fuzzy qualified differential equation. At the same time, the approximate numerical solution of fuzzy permeating flow equation is relevantly discussed using the fuzzy structuring element method. It is very useful analyzing tool to forecast the tendency and position of goaf spontaneous combustion by applying the fuzzy forecasting technique.
