Abstract

The paper presents a solution to the problem on the non-stationary heat exchange between ventilating air and rocks. The integral relationships for calculating temperatures of air and surrounding rocks are obtained by using the Laplace transforms. Also, their convergence is tested on the example of emergency under reversal of main ventilating facility in a winter period. It is shown that the short-duration heat exchange phenomena should be calculated on the approximation of small times.
