The purpose of research is to study the effect of non-detonating gas-generating energy-active components in the charges on the explosive loading of solid media in near and far from the charge zones. Research methods - assessment of the workability of the charge by the parameters of the camouflage cavity, instrumental determination of physical factors, sieve method for determining the particle size distribution of the destroyed models, statistical processing of the obtained results. The use of non-detonating gas-generating energy-active components in the form of an outer shell of the charge of BP allows to reduce the re-grinding of the medium in the near-charge zone and to increase the intensity of crushing in the middle and far zones, which increases the efficiency of the enterprises that produce non-metallic minerals. Keywords: gas-forming additive, explosive, charge, rock, camouflage cavity, detonation products, brisant action. Product Description popup.authors Bezzubchenkova Maryna V. Dzekun Yurii V.
