The problem of building a non-stationary temperature field round the working in the massif with ascending hot water flows is raised. The method of mathematical modelling is shown to be advisable in solving the problem. It is suggested that calculation of heat at the end of the working be done by determining the weighted average temperature of the transfer surface fey substituting the coefficient of heat irradiation a for the coefficient of non- stationary heat exchange K_t in the known calculation dependences.
