Influence of tectonic stresses on deep open-pit slope stability. Development of a concept of geomechanical substantiation of rational angles of slopes in tectonically stressed rock massifs
The paper studies influence of tectonic stresses on deep open-pit slope stability. Aspects of geomechanical substantiated rational constructions for open-pit walls in tectonically stresses rock mass have been shown. Results of stress distribution at the vicinity of large open-pits are presented. A methodical approach has been proposed for assessing pit wall stability which considers hierarchically-blocked structure and natural field of gravity-tectonic stresses.
