Abstract: 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.
