Abstract
ENG: Based on the analysis of solutions to the classical problems of soil mechanics and geomechanics on determining the
critical height and angle of the slope, as well as active and passive pressure on the enclosing structures, to identify the
optimal strength criteria and the limits of their application, which allow predicting the destruction of ideally free-flowing,
ideally plastic rocks, as well as rocks characterized by internal friction and specific cohesion, which is necessary for
calculating the strength and stability of underground and open mine workings in the supercritical region - after the destruction
of the near-contour region.
The areas of application of some criteria for the strength of soils and rocks are outlined and substantiated. It is shown that,
in contrast to the known strength criteria of Z.T. Benyavsky, Hoek - Brown and A.N. Shashenko Coulomb - Mohr strength
criterion and our proposed modification of the strength criterion of A.N. Shashenko allow predicting the destruction of
ideally - free flowing, ideally - plastic rocks, as well as rocks characterized by internal friction and specific cohesion.
