The choice of support design for mine excavations driven beyond the influence zone of stoping in the conditions of permafrost is governed by the service life of the excavations, geomechanical behavior of surrounding rock mass and by working temperature range of ventilation. The research findings on influence exerted by temperature on stress state of rock mass around a single tunnel are presented. Based on solution of quasistatic thermo-elastic problems, the mechanisms of change in the stresses and displacements at...
