The paper describes methods developed to determine the change in the width and height of the collapse of blasted rocks, as well as the width and height of the retaining wall during the explosion of borehole charges using emulsion explosives depending on the parameters that determine the energy characteristics of emulsion explosives. It gives the details of the physical and mechanical properties of rocks and the parameters of the explosive block, a mathematical model describing the action of an explosion of a borehole explosive charge in an array, on the basis of which the kinematic parameters of rock expansion are determined.
