综放面采空区温度场动态数学模化及应用

Dynamic Computer Simulation of Temperature Field in Goaf Areas of Fully Mechanized Roof Coal Caving Face

根据采空区浮煤氧化自燃过程的主要影响因素，建立了采空区温度分布的数学模型，计算分析了采空区浮煤温度分布随工作面推进速度的变化规律，确定了工作面的最小推进速度．并用ＦＯＲＴＲＡＮ语言编程。

Based on main factors of coal spontaneous combustion, a mathematical model for the dynamic process of coal self heating in mine goaf is put forward. This model has been applied to coal face 8916 in Xinzhouyao Coal Mine, Datong Mining Bureau, to predict the probability of spontaneous combustion.
