This paper presents a theoretical approach to the problem of heat and moisture pick-up of ventilation airalong wet roadways.
Firstly, the variation of temperature and humidity of ventilation air with distance along a uniformly wetroadway is analysed for different degrees of wetness; the wetness being expressed by a wetness fraction (f). Theresults show that the variation of both temperature and humidity are remarkably influenced by the degree of wetness. Under somecondition, it is possible that the air temperature (dry-bulb temperature) decreases with distance, whereas the relativehumidity increases.
Secondly, variation of the temperature and humidity along a partially wet roadway is calculated and thetemperature profile in the rock around the roadway is presented. By using a newly introduced value e and the resultsfor the uniformly wet roadway, a new method is proposed for calculating the temperature and humidity for a partially wet roadway.
