INFLUENCE OF OVERSIZE YIELD FOR THE PRODUCTIVITY OF LOADERS

Abstract

Industrial observations were carried out to determine the actual output of oversized mines at underground mines (excluding nonmetallic ones) of the Norilsk Nickel. The research methodology provided for measuring the actual output of oversized after borehole breaking of ore massifs of chambers at the underground mines "Oktyabrsky", "Taimyrsky", "Komso-molsky", "Zapolyarny" and "Mayak" of the ZF Norilsk Nickel. A decrease in the productivity of loading and transport vehicles for the shipment of rock mass from the chambers through a re-duction factor associated with the percentage of oversized cargo is determined.
