Theoretical and experimental bases of forecasting the thermal regime of mines of the North
Abstract
The physical model of thermal processes in mine workings and frozen, thawing and freezing rock mass at the modern level of research can be formulated as follows: the temperature of mine air varies along the length of workings g and in time t as a result of its heat and mass exchange with the rock massif, minerals transported along the workings and ice (water) in the workings, as well as under the influence of “absolute” heat emissions and fluctuations in temperature t0 and relative humidity ф0 at the beginning of the ventilation path. In this case, only the intensity of “absolute” heat emissions can be considered constant in time ...
