Abstract
The article proposes mathematical model of heat exchange between open pitwall rocks and atmosphere for forecasting temperature field in permafrost strata, daily change in radiative balance, slope angle and surface orientation, and influence of contiguous benches. In terms of Udachny Open Pit Mine, time dependence of pitwall sloughing layer thickness is estimated under cyclic effect of freezing-defrostation in rocks having different freeze resistance.
