METHOD OF SINGLE-FLOW STEPLESS TRANSPORTATION OF ROCK AND MINERAL DEPOSITS FROM MINE DURING ITS CONSTRUCTION AND OPERATION Russian patent published in 2013 - IPC E21F13/00 B65G53/30 

FIELD: mining.

SUBSTANCE: extracted rock is unloaded from a trolley to a bunker, from which it is supplied to a crusher and after that to a sump, in which a hydraulic fluid mixture of the required consistency is formed from crushed hard rock and water, which is pumped out of the sump with a low-pressure soil pump and supplied in turn to each segment of tubular loading device (TLD) arranged in the mine. Besides, pressure water is supplied from the reservoir installed on the surface by means of a pump via the pipeline arranged in the mine shaft to wash out the hydraulic fluid mixture from TLD and transport it via pressure pipeline to the surface to a sludge pond or a concentration plant, and the rest water in the segment after hydraulic fluid mixture washing-out is supplied via drain pipeline to the sump to form hydraulic fluid mixture.

EFFECT: creation of stepless single-flow scheme of hydraulic transportation for any development depth of mineral deposits at construction and operation of mines.
