Abstract
Wedge-shaped deformations in the rock masses occur along the sliding surfaces formed by several diagonal fracture systems, which may have different genesis and, accordingly, different shear characteristics along them. The method of backward calculations makes it possible to differentially determine the shear characteristics for each fracture system by analyzing a set of actual wedge-shaped in-rushes recorded and geometrically defined in the benches of open-pit mines. This is done by formulating a system of transcendental equations based on the equation of rock wedge safety factor and solving it sequentially using the least square method for all the recorded wedge-shaped deformations. A practical validation of this method was performed and the shear properties of the fracture surfaces were found for the Eldorado open pit mine, which eventually provided a basis for increasing production of the mining operations.
