Special Issue Information

Dear Colleagues,

Deep-sea minerals are major resources that will ensure sustainable industrial development in the future; their exploitation has been one of the most active research areas in natural mineral systems, mineral resources, mining, and mineral processing. The purpose of this Special Issue is to provide a platform for introducing and discussing the most recent development in the exploitation, transportation, and processing of deep-sea mineral resources, as well as the environmental impact and economic analysis of deep-sea mining. The papers published in this journal are open access, which will accelerate the spread of novel ideas among researchers in this community. High-quality papers on both novel methods and practical applications are welcomed. In order to provide a comprehensive insight into the development of this research area, this Special Issue is open to both review and original research papers. Topics for this Special Issue can include, but are not limited to:

  • The application and development of the deep-sea mining system;
  • Excavating and collecting technology for deep-sea minerals;
  • Lifting technology for vertically transporting minerals from the sea floor to the surface;
  • Surface transport technology for deep-sea minerals;
  • Ship-borne dewater system for deep-sea mining;
  • Deep-sea mining operation support system;
  • Environmental impacts of deep-sea mining;
  • Economic and technical considerations for the exploration and exploitation of deep-sea minerals;
  • Metallurgical processing of deep-sea minerals;
  • Sustainable processing of deep-sea minerals.

Seabed soil layer composed of soft sediments, which has a high water content, low bulk density and low shear strength, has great influence on deep-sea engineering devices. Therefore, accurate measurement of the mechanical properties of seabed sediments is a prerequisite for the construction and safe operation of deep-sea projects. In this study, a deep-sea engineering geology in situ test system was developed to measure cone resistance, sleeve friction, pore pressure and shear resistance in seafloor sediments. The system was tested on land, and the feasibility of the system was verified. We conducted sea trials in the South China Sea and acquired datasets from five stations. The data were analyzed using the Eslami–Fellenius soil classification map, and the soil classification of the site was obtained. The obtained values of cone resistance, sleeve friction, pore pressure and shear resistance can provide mechanical data support for deep-sea engineering in this area. Full article

To mine the cobalt-rich crust deposits at the substrate of the slope of the seamount, the mining vehicle needs to walk on the slope and strip the cobalt-rich crust from the substrate. To achieve safety and control, the vehicle needs to stably walk on the slope. In this paper, we propose a modeling method for mining vehicle performance based on slope stability and antislip and antiskid conditions. The specific energy of three types of mining vehicles is compared based on dimensionless parameters. The dual-drum type is determined to be the best choice in terms of energy costs, followed by the down-milling type. The performance of the compact mining vehicle based on different slope angles and two sea trial results in the South China Sea indicate that the slope angle, substrate, and crust have significant effects on the stability. The modeling method proposed in this paper can help designers estimate the structure and power of mining vehicles based on mining stability. Full article

Lifting coarse mineral particles from thousands of meters of seabed to the supportive vessSel is a crucial part of exploitation of deep-sea mineral resources, and the vertical transportation part is a key component of the deep-sea mining system. Three typical vertical transportation schemes are discussed and compared from the aspects of working mechanism, structural scheme, transportation capacity, system efficiency and implementation feasibility in the context of commercial exploitation of deep-sea polymetallic nodules. The conclusion is that the hydraulic pipeline lifting system with a centrifugal pump is a comprehensive scheme. Furthermore, the basic composition and function of the hydraulic lifting system are introduced, and the transportation performance indicators and technical requirements under commercial mining conditions are analyzed. As the key equipment of the lifting system, the structural characteristics, design theory, transportation performance analysis methods and research progress of the lifting pump are described. A 1000 m sea trial was carried out. The lifting system, the tests of the centrifugal pump and the sea trial are introduced. Full article
