A procedure by finite difference method is described for calculating the temperature of mine air as it passes through a dry roadway. The accuracy of the calculation by this method is discussed, using the values of the exact solution by van Heerden. For an example, the calculation of air temperature is carried out when the temperature and volume of intakesairchange after one year from the start of ventilation.
