It is established that the geothermal field of a massif around underground structures located above the neutral layer is non-stationary because of the influence of solar radiation. Below the above marked layer, the formation of the geothermal field of the subsoil is due to the process of depths and is stationary. The definition of these fields is necessary for the performance of the thermal physical calculation of the ventilation and the specification of the air consumption of the underground facilities of the metro by the thermal factor. The paper gives formulas, tables and graphs with the help of which it is possible to reliably determine the sought-for geothermal fields
