Studies on Pressure Impulse Dynamics When Operating a Modular Solid-Fuel Shock Wave Generator

Abstract

Increasing the efficiency of using explosion energy to destroy a rock massif when operating solid-fuel shock wave generators, which include an explosion-reactive system, depends, to a considerable extent on the parameters of the pressure impulse, on the physical and mechanical properties of the rocks, and on the mining and geological conditions. Simulation results for the parameters of an explosion impulse during the operation of an explosion-reactive system are presented, and pressure impulse amplitudes under different pulse duration modes are studied. A rational mode of operation of the explosive system is determined for the development of rocks with strength coefficient f = 5–20 according to Profesor Protod’yakonov’s scale has been determined.
