Abstract

The invention discloses a method and a device for extracting volcanogenic massive sulphide ore deposit on seabed, which comprise the following steps that: (1) a seabed mining vehicle, a seabed conveyor system, a seabed collecting system and a seabed excavating mechanism are placed on the seabed from a new-moon pool in the middle of a surface workboat; (2) the seabed mining vehicle is started to move to an working face, then a cutting head drive device of the excavating mechanism arranged on the seabed mining vehicle is started and controlled to carry out excavation and cutting operation, and under the excavation and cutting action of the cutting head, sulfide ore is crushed and the crushed sulfide ore falls into an ore chute; (3) the collecting system is started to convey the sulfide ore in the ore chute to an intermediate bin; and (4) the conveyor system is started to convey the sulfide ore in the intermediate bin to the surface workboat. The invention also comprises a corresponding device. The method is low in extraction cost, high in efficiency, simple in equipment, convenient in operation, and suitable for large-scale extraction of volcanogenic massive sulfide ore deposit on seabed.

Description

technical field [0001] The invention relates to a mining method and device for sulfide ore, in particular to a mining method and device for seabed hydrothermal sulfide ore. Background technique [0002] Seabed hydrothermal deposits, as a strategic seabed polymetallic mineral resource, are rich in iron, copper, lead, zinc and silver, gold, cobalt, nickel, platinum and other metals. With the deepening of understanding of seabed hydrothermal deposits, the gradual understanding and mastery of deep sea mining technology, and the upward trend of metal prices and other favorable factors, many international mining giants are actively conducting research on seabed hydrothermal deposit mining technology explore. The article "Current Status of Seabed Hydrothermal Sulfide Mine Development" published on pages 1-4 of Issue 5 of 2008 in "Mining Research and Development" introduced the seabed sulfide mine mining system proposed by Neptune International Mining Company. The system consists o...
