METHOD OF OPEN PIT MINING WITH HELP OF WHEEL-TYPE MINERS, SELF-PROPELLED HOPPERS AND DUMP TRUCKS Russian patent published in 2014 - IPC E21C41/26 E21C47/06

Abstract RU 2517262 C1

FIELD: mining.

SUBSTANCE: rock loosened by wheel-type miner is dumped by miner discharge arm belt conveyor onto that of self-propelled two-section hopper turn bar. Then, it is dumped into hopper sections rock from under which, with no outage of hopper and miner displacing in synchronism and in parallel, it is dumped cyclically into dump-trucks. Said dump-trucks move along with said hopper at loading.

EFFECT: higher efficiency of mining due to decreased downtime of miners and dump tricks.
