MUCK CLEANUP AT STEEPLY-DIPPING DEPOSITS Russian patent published in 2014 - IPC E21C41/22

Abstract RU 2520986 C1

FIELD: mining.

SUBSTANCE: proposed method comprises laying of perforated pipes to be advanced as ore is broken, filling said pipes with substance generating the power for broken ore cleanup and broken ore cleanup. Explosive is used as power generating substance. Explosive is fitted in said pipe and initiated while ore cleanup is performed by blast shock wave. Pipe perforations are located so that hole axes are parallel with laying side plane which allows pipe breaking in line of said holes and directing major part of blast air wave to lying side.

EFFECT: higher quality of laying side cleanup of broken ore.
