Physical and mechanical properties of overburden rocks of the Tikhvin bauxite deposit

Abstract

During open-pit mining of bauxite deposits at a number of mines in the Tikhvin bauxite-bearing region, deformations of pit sides and overburden dumps are observed. Deformations manifest themselves mainly in the form of landslides and slumps. The extent and dynamics of landslide phenomena at different mines vary. In some cases, landslides significantly complicate mining operations and increase the cost of minerals.
