Nowadays, amount of reserves of shallow lied and easily accessible minerals becomes smaller. That's why, for the purpose of support and increasing of extraction capacity, mining enterprises have to start the development of more hardly accessible and deep lied deposits with simultaneous increasing of intensity of mine operations. Increasing of depth increases the temperature of environment rock massif, and reinforces the influence of anthropogenic sources of heat emission on formation of unfavorable microclimatic conditions. This article gives the modern approaches to development of technical solutions on controlling of thermal mode of mining enterprises on the basis of use of software and hardware complexes of different level, corresponding to criteria, providing the minimum of total capital and exploitation costs. There are given the methods of modeling of aerothermodynamic processes in excavations of deep mines, which make possible to realize the offered approaches to development of engineering operations on regulation of thermal mode. According to this, on the first stage, on the basis of experimental data for existing and project data, the thermal model of mine (site) is developed for prospective excavations. This model can include both one excavation or several excavations within a site; and tens, hundreds and thousands of excavations. Designed thermal model makes possible to realize the multi-method modeling of application of mine-technical and thermal-technical measures of development of thermal mode and estimation of their efficiency, including economical calculations of capital and exploitation costs. There was defined, that methods of distributed supply of cooled air in underground working areas are most preferable. This article shows the examples, which describe the fact, that application of offered approach on the basis of application modern software and hardware complexes makes possible to solve problems of controlling of thermal mode of various underground mines and make a reasoned decisions on normalization of microclimatic conditions in excavations, taking into account individual peculiarities of mines.
