Movable distributive continuous exploitation method for deep sea mineral resources

Abstract

The movable deep sea mineral resource exploiting system consists of under water positioning base point in the marine mining area, movable distributing mining vehicle, movable ore bin matching the exploitation amount, initial separating and crushing unit capable of inhibiting depletion rate and matching mineral granularity, conveyer to the ore raising unit, movable ore raising unit with driving plant and pipeline, movable underwater power distributing station, movable main control station, surface exploitation ship, transportation ship, etc. The present invention is adaptable to the exploitation of deep sea mineral resources, especially base rock mineral resources and deposit mineral resources, and has high production rate, high collecting rate, low exploitation cost, high reliability, and less marine environmental pollution.

Description

Technical field: [0001] The invention relates to a mining mode of marine mineral resources, in particular to a method for continuous mining of movable and distributed deep-sea mineral resources of deep-sea bedrock deposits and sediment deposits. technical background: [0002] In recent years, with the increase of the world's population and the sharp increase in the use of mineral resources by humans, land resources have become increasingly scarce and exhausted. Although there are huge reserves of marine mineral resources, they have not yet been developed and utilized. Therefore, countries, especially developed countries, have turned their attention to the ocean, and have taken the development and utilization of ocean resources as a basic national policy. Many famous politicians and economists have predicted that the 21st century will be a "marine economy era". [0003] Japan invented a continuous linebucket mining method (Continuous linebucket system), referred to as the CL...

Problems solved by technology

The disadvantage of this method is: it is still a kind of intermittent mining form in essence, and it is difficult to control the trajectory and collection path of the tow bucket in the deep sea, which makes it difficult to improve the collection efficiency of mineral resources; It is difficult to control the movement posture and mechanical properties of the drag bucket, which increases the dilution rate of mining; the mineral resources will spread during the lifting process of the drag bucket, causing damage to the marine environment including marine organisms

Their disadvantages are: for the pipeline lifting type, its underwater devices are integrated, and each underwater device requires a set of lifting pipelines, which is difficult to form an economical mining method; in order to achieve a certain output, its underwater devices It must be made very large, it is difficult to meet the requirements of adapting to the micro-topography of the seabed, and the collection rate is reduced; the equipment is huge, it is difficult to maintain, and the reliability is reduced; collecting and lifting a large amount of seabed sediments will pollute the marine environment

For the submersible mining method, it shuttles between the sea surface and the seabed, which makes it difficult to increase productivity and increase production costs; it has high requirements on the reliability and safety of equipment and lacks practicability
