Abstract

The regularities of the temperature regime of boreholes and mine workings, especially in conditions of changes in the aggregate state of the surrounding rocks, are described by extremely complex analytical expressions. The concepts of the coefficient of unsteady heat exchange kτ and the coefficient of heat exchange intensification at the aggregate transition kagr.
