Abstract The paper considers an important problem of assessing the stability and strength of various elements of underground structures. The work complements the general scientific and methodological base of such concepts as “stability and strength of elements of underground structures” and forms the principles of selection the criteria of “stability and strength of elements of underground structures”. The proposed approaches and technologies are demonstrated on the examples of solving applied problems of geomechanics. The first of the problems considered is the problem of the strength of a multilayer rock massif during mining operations. The strength of the massif is evaluated based on various criteria. Some recommendations on the choice of strength criteria for this type of problem are given. The second problem is the problem of assessing the long-term stability of the underground structures of a large cross-section. The long-term stability of an underground structure of non-standard geometry is considered taking into account the rheological effects occurring in the rock massif.
Keywords
