Abstract

The paper investigates the influence of the block structure of the rock mass on cohesion, internal friction angle, and deformation modulus of rocks. The dependence of these characteristics on the geological strength index (GSI) of the rock mass, which reflects the degree of its disturbance, has been established. The results of recalculating the strength and deformation properties of granodiorites depending on the depth of the quarry wall and the quality of the rock mass near the quarry wall are presented.
