摘要

FIELD: mining.;SUBSTANCE: bench to model impact of blasting products at tamping of blasting holes includes a high pressure chamber closed with a cover on top with a cut disc, and a measurement complex. The cover is connected with a blast hole imitator made in the form of a pipe with notches in the lower part, simulating cracks in the rock, and slots in the upper part simulating damaged massif of rocks.;EFFECT: modelling of impact of blasting products at tamping of blasting holes.;2 cl, 2 dwg
