Description

Technical Field

[0001] The present invention relates to a test system in the technical field of deep - sea mining engineering and its usage method, in particular to a deep - sea mining full - process pilot test system capable of carrying out full - process tests of a pipeline - lifting mining system and its usage method. Background Art

[0002] The vast ocean floor is rich in mineral resources, which are the most important alternative resources for land - based metal minerals in the 21st century. With the substantial increase in the demand for critical minerals in the global energy transition, the supply of land - based mineral resources is tightening, and the global mineral supply chain is showing an unstable trend due to geopolitics, transportation, etc. Against this background, deep - sea mining has become the focus of attention of various countries, and many countries are increasing investment in research and development to make technical reserves for the arrival of the "ocean economy era". The proven deep - sea mineral resources with development prospects include polymetallic nodules, cobalt - rich crusts, polymetallic sulfides, etc. Most of them are located at depths of several thousand meters, and the ocean depths and seabed topographic environmental conditions of different mineral resources vary greatly, which poses extremely high requirements for the development of marine mineral resources.

[0003] Deep - sea mining systems have gone through four main technical forms: drag - bucket type, continuous line - bucket type, ocean - shuttle type, and pipeline - lifting type. Among them, the pipeline - lifting mining system has become the most promising commercial deep - sea mineral exploitation system due to its advantages such as continuous operation, relatively low cost, and high mining efficiency. The pipeline - lifting mining system mainly consists of multiple subsystems such as a seabed mining vehicle, a vertical lifting system, a surface support system, and an in - situ ore sorting system. As Figure 1 shown, the mining process requires collecting ore from the seabed at a maximum depth of 6000m and vertically lifting it to the water surface for sorting. The structure of the whole system is complex, with numerous influencing factors. Moreover, due to the extremely complex deep - sea environment, the stability, safety, and efficiency of the pipeline - lifting mining system require a high degree of coordination among various subsystems. This not only requires research on the equipment and key technologies of each subsystem, but also research on the full process of the deep - sea mining system. The cost of sea trials for deep - sea mining is huge, with numerous uncertainties and extremely high trial - and - error risks. At present, there is a lack of a mature and complete sea - trial platform and theoretical guidance for the system. Existing research basically stays at the research on the key technologies and equipment of each subsystem, and there has been no experimental research on the full process of deep - sea mining.
