摘　　要：为准确预测矿井高温工作面气候条件,有必要对工作面通风系统进风井筒及巷道的风流温度进行计算。根据进风井筒及巷道的热湿交换特点,运用有限差分方法,分别建立了进风井筒及巷道的风温迭代计算数学模型;运用VB 6.0语言,编制了高温矿井进风井筒及进风巷道风温预测程序;应用于新巨龙矿井现场,计算得到了其进风井筒及巷道的风流温度。计算和实测所得风温误差较小,预测方法和计算程序是可靠的。To forecast the climate conditions of the mining face with high temperature accurately,the calculation of the air temperature of the intake air shaft and airway is necessary. According to the heat and moisture exchange in the intake air shaft and airway,the iterative computation model of the air temperature was set up by the finite difference method. Then the air temperature prediction procedures of the intake air shaft and the intake airway were developed with VB 6. 0. The air temperature of the intake air shaft and airway of the mine ventilation system was obtained after applying the procedures to field trial in Xinjulong Mine. The errors of the calculated and actual measurement air temperature are relatively small,which indicates that the prediction method and calculation procedure are reliable.
