There is now an escalating demand for temperature prediction simulations applicable to under ground environments. But It is troublesome to analyze the heat transfer across the wall of airways taking the heat conduction in the rock mass in which hot spring flow into consideration. Then first, authors investgated it by the energy balance analysis based on the meteorological observation at a drift under development in Toyoha mine. Secondly, authors exercise pre-calculation of the rate of flow, temperature and humidity of air current in a tunnel model using the investigated result.
