Temperature effects on stress–strain behavior of underground openings in permafrost zone
Abstract The authors describe the research results on the temperature effects on the stress–strain behavior of rock mass around single openings driven in permafrost beyond the influence zone of stoping. The variation patterns of stresses and displacements in rock mass and at the boundary of an under...
