Abstract

About 30 % of the mountain weight extracted on rubble the enterprises, at explode and the subsequent mechanical crushing, the fraction less makes than5 mm(elimination) which practically does not find selling and litters an environment. The output of elimination is influenced essentially with detonation characteristics explosives.
