Essay

The thesis is dedicated to substantiation of rational parameters of explosive charges with gas-forming components, which ensure increasing a receipting the standard factions at the open-pit mines rock. Ascertain that location gas-forming substances in the manner of separate sections reduces a formation superfluous-broken factions in zones of array, verging to this sections, ensures interference interaction of stress waves, generated by adjacent explosive contain sections. This to redistributed an energy of blast from shatter zone in transition zone that reduces a receipt the oversize factions. For the first time ascertained that distance between radial rifts depends on tensile strengths variation and velocity of increasing a pressure. Designed method of calculation of parameters of composite charges, which ensure of receipting maximum of the standard factions in volume of rock blasted. Economic effect from introducing recommendations has formed 19 thousand grn.
