Zusammenfassung:	The paper presents the methods for the numerical modeling of complex air-gas-heat dynamic processes that take place in underground mines. It is shown that modeling the condensate moisture migration, air movement due natural draft as well as heat and smoke propagation during fire may be based upon the earlier developed conjugate model of heat exchange between mine air and a rock mass. The qualitative and quantitative analysis of the effect exerted by thermal compressions of air in shafts on the air movement in mines is performed.
