Abstract
The mathematical methods of forecasting microclimate conditions in an arbitrary layout network of excavations are developed based on analysis of formation of thermal environment in mines. The mathematical models allow calculation of heat distribution in excavations, considering hydrostatic compression-expansion of air in vertical and inclined workings, presence of heat liberation (absorption) and moisture transitions.
