THE EFFECT OF ROCK MASS STRESSED-DEFORMED STATE ON THE STABILITY OF PIT EDGES AREAS

Abstract

According to the results of geotechnical studies
using information on the rock mass stresseddeformed state and jointing, the surfaces of
weakening, as well as rock mass structural
elements bedding, the assessment of stability of the
pit edge part is given, that has shown that the
stability of near-edge rock mass part in the
presence of steep and flat falling fracture systems
depends not only on physical and mechanical
properties of these fracture systems, but also on the
parameters of the tectonic stress field.
