Development of a methodology for determining the economic efficiency of cyclic-flow technology schemes for rock mining using mobile crushing and reloading-conveyor complexes

The article describes the methodology for calculating energy consumption when transporting overburdened rocks to the inner dump at Angren section using belt conveyors and dump trucks. By results of research, it is defined that at working off overburden benches using motor transport-specific power inputs for loading and transportation to internal dump are on 21 % higher than at use of mobile crushing-overloading-conveyor complexes.
