Abstract: In this study, a computation model of temperature and humidity for single airways has been designed based on the prediction and control of underground coalmine climate environment. By comparing the actual data measured in airways of different usages and years with the simulation results of temperature and humidity, the paper intends to verify the accuracy of the calculation model and application feasibility on ventilation network. The results of various airways by calculated and measured are basically coincidence, which can reflect that theoretical computation formula of simple single tunnels is suitable for prediction calculation of air temperature and humidity in ventilation networks; The temperature and humidity of airflow in partly wet roadway can be calculated by the uniform model.
