DEVICE FOR DISCHARGING MATERIAL EXCAVATED IN UNDERGROUND WORKINGS Russian patent published in 2018 - IPC E21F13/08 B65G21/14 

FIELD: mining.

SUBSTANCE: invention relates to mine transport. Disclosed is a device for transferring a material excavated in underground workings in a mine road stretch, comprising a belt conveyor system, which comprises endless conveyor belt (17), and comprising a conveyor section which is continually extendible along a conveyor stretch in step with the rate of advance. Belt conveyor comprises in the conveyor stretch at least one first support device (7), movable in the longitudinal direction of the conveyor stretch, for endless conveyor belt (17) and a plurality of inter- coupled conveyor belt vehicles (9, 15), movable in the longitudinal direction of the conveyor stretch, which in each case carry support elements for endless conveyor belt (17). Arranged between first support device (7) and plurality of conveyor belt vehicles (9, 15) is second movable support device (8) for endless conveyor belt (17), which is coupled to first support device (7), comprising guide means for the introduction of conveyor belt vehicles (9, 15) into the conveyor stretch from a position arranged next to the conveyor stretch. At least one part quantity of conveyor belt vehicles (9, 15) arranged in the conveyor stretch are guided in inter-coupled movable guide frame elements (10) in the longitudinal direction of the conveyor stretch.

EFFECT: proposed device provides continuous movement during the elongation of the conveyor stretch, as well as during retraction of the elongation.
