Abstract

This paper substantiates application of pit conveyors at the stages of pit rework and underground mining beyond-edge reserves. Heavy pit lift transport is not efficient under conditions of the low enterprise output capacity. Thus, variants of further increasing its efficiency shall be stipulated. The paper considers the methods to increase efficiency of pit conveyors depending on the type of the electric drive and exploitation mining conditions. It provides calculation of electric power costs dependent on adjustability of the electric drive, presence of the pit to accommodate a stock dump at the site and replace electric motors. It is found that it is reasonable to replace electric motors of the conveyor with those of a higher energy efficiency class at the stage of the pit rework during underground mining beyond-edge reserves at the operation of the inclined conveyor.
