The researching results of temperature impact on stress-strain behavior of the solid near single rooms, advanced at ever-frozen soils out of impact zones of actual mining are shown. Regularities of displacement and stress changes in containing solid and on contour of the working are established in dependence on its operation time and ventilating temperature. It is shown that in conditions of Aykhal mine, Alrosa Enterprise, at working depth 350m and its ventilation for 3 year under the temperature 20°С the working convergence in vertical direction is collated with elastic displacements being occurred by drive. The approach allowing to determine the stability category of rock mass based on estimation of predicted displacements of working under its ventilation is proposed. Carried out investigations are aimed for development of methodologic and regulating documents to validate parameters of working support at cryolitic zones.
