Abstract

The article presents the results of theoretical studies describing the process of crack growth during the processing of rocks in mills. The mathematical apparatus of the theory of oscillation of round plates is used to determine the energy parameters of the crack propagation process. An expression is found for identifying the energy of deformation of the crack wall as a result of impact. The parameters of the shock pulse acting on the crack wall are determined. The value of the impact energy necessary for the destruction of the rock has been established.
