The paper describes estimates developed for the change in the loosening coefficient of the rock mass depending on the mass of the emulsion explosive charge and the grid of wells. The parameters of blasting in a clamped medium have been determined. A formula for calculating the height of the retaining wall during the explosion of borehole charges using emulsion explosives has been developed. It includes the main parameters and determines the physical and mechanical properties of rocks, the parameters of the blasted block and the mass of the emulsion explosive charge.
