Abstract

Crushed rock shear tests are carried out to determine stability of a tailings pond dam. The tests allow finding the rock strength at different grain composition and density of rocks, as well as at different shear ring diameters and normal pressures. It is found that the internal friction angle and cohesion range as 35–40° and 0.0256–0.0293 MPa, respectively, in compacted rocks, and as 25–30° and 0.0163–0.0184 MPa, respectively, in uncompacted rocks.
