the south China sea water area contains abundant metal and nonmetal minerals, however, the minerals are mostly distributed in the deep sea seabed of the sea area with the water depth of over 5000 meters, and the large-water-depth operation also becomes a great challenge for deep-sea mining. Current deep sea mining systems typically include a mining assist vessel at the sea surface, a subsea mining vehicle, and a vertical transport system connecting the two. Traditionally, subsea mining vehicles collect ore from the seabed, which is then crushed and pumped into a vertical transport system. The vertical transport system typically contains risers through which the collected ore and seawater mixture is transported vertically from the seafloor to a mining auxiliary vessel at the surface. Conventional lift systems are typically hydraulic or gas-lift. In the hydraulic lifting system, a plurality of booster stations adopting centrifugal lifting pumps are arranged along different depths of the vertical pipe so as to maintain the internal pressure of the vertical pipe. In gas lift systems, compressed gas is injected to an intermediate depth, and ore solids can thus be lifted by a gas/liquid/solid three-phase mixture.
To date, there is no deep sea mining operation on a full scale. Especially the low efficiency and high cost of conventional vertical transportation systems, and with increasing water depth and increasing complexity, it is not known whether they can work effectively after water depths exceeding 6000 meters. Therefore, there is a need to develop a more efficient, stable, and economical vertical transportation system that can transport deep sea ore to the sea surface. Therefore, an efficient and energy-saving deep-sea mining system which is simple in structure, low in cost and suitable for large-water-depth operation is needed. Meanwhile, the pollution condition of the deep sea mining system to the environment is considered, and the energy-saving and environment-friendly deep sea mining system is provided.

With the research of researchers on deep sea water areas with water depths of 6000-11000 m, the technology of underwater vehicles and manned vehicles is gradually developed. The equipment adopts buoyancy materials and counter weights for ballasting, and realizes the sinking and floating of the deep submergence device through unpowered floating technology. The technology is used for continuously lifting the deep-sea mining operation so as to overcome the limitations of the traditional deep-sea mining lifting system.
