Abstract
The
problem of determining the stress-strain state in the vicinity of an opening
with an arbitrary shape using the measurements of the Cauchy stress vector and
displacement vector has been solved. The states of elasticity, plasticity, and
overlimiting deformation are considered. The obtained results allow to
determine rapidly the resource capabilities of rock mass resistance to failure
on the contour both in a buried opening and in opencast mining.
