COMPLEX TO MINE IRON-MANGANESE CONCRETIONS IN WORLD OCEAN OFFSHORE ZONE Russian patent published in 2010 - IPC E21C50/00 

Abstract RU 2405110 C1

FIELD: mining.

SUBSTANCE: proposed complex comprises base ship articulated with mining plant that comprises rolling gripping device mounted on skis, and transport device that joints mining plant with base ship. Rolling gripping device is made up of vaned drum running on horizontal axle articulated with the drive. Drum vanes are arranged with minimum clearance with respect to cylindrical casing inner surface. Casing perforated surface holes feature diametre smaller than minimum crosswise size of mined concretion. Forked vanes have deflections. Said casing communicates via intake chute of narrowing cross section with ground pump suction branch pipe. Said pump is arranged in skis crosswise girders on the side of casing, opposite the mining plant travel direction. Ground pump delivery branch pipe communicates with perforated pipeline arranged on the casing and secured thereto, that can be connected with flexible delivery pipeline. Said delivery pipeline is arranged coaxially with ground pump pressure branch pipe and directed along casing lengthwise axis of symmetry.

EFFECT: higher efficiency, simplified design, reduced costs.
