Title An improved method of predicting underground climate
Bibliographic information Feb. 1982, Vol.19, No.1, p.31-38. Illus. 20 ref.
Abstract Proposal of a more accurate method of precalculation that takes into account the observation that the temperature of the airway wall at which water vaporisation occurs is lower than the temperature in case of no vaporisation. Geothermal heat flow from dry rock therefore increases, and temperature and humidity of air current are affected. To perform the calculation by this method, the authors present a new method for determining the wetness factor. Applicability and accuracy of this method were examined by comparing the calculated results with the measured results. The comparison showed that the new method gives temperature and especially humidity predictions with improved accuracy. Improved prediction of underground climate can be expected from simultaneous calculation of rate of flow, temperature and humidity in the underground network.
