Application Of Solid Buoyancy Materials In Marine Mining Systems

Deep-sea mining technology is the core of the development of deep-sea metal mineral resources, including the collection of deep-sea minerals, subsea hose conveying systems, subsea mineral preparation and loading, transmission and distribution, lifting of minerals from the deep sea to the sea surface, sea surface support, and dynamic positioning of mining ships And monitoring and control of mining and transportation processes. Deep-sea mining is a multi-link series system project. It operates in an environment that is thousands of meters deep, under the influence of ocean currents, wind and waves, and seawater corrosion. Moreover, polymetallic nodules are produced in extremely low-strength soft mud, and cobalt-rich crusts are produced In the seamounts and ridges, the working conditions are harsh and the mining technology is very difficult, which puts forward high requirements and a long period of time for the development of technology. The research and development cycle of deep-sea mining technology needs 15-20 years to achieve the goal of the deep-sea pre-mining intermediate test. The mining system in my country's industrial mining consists of five major parts: mining and lifting subsystem, monitoring subsystem, mining ship, and transportation support subsystem. The mining process is that the mining machine carries the collecting head to collect the polymetallic nodules spread on the seabed, and after being broken, it is sucked up to the sea surface ore ship through the hose, the intermediate storage (buffer) and the ore lifting hard pipe. Mining and lifting are the core technology and key components of the marine mining system. Solid buoyancy materials play an important role in the mining and lifting of the seabed mining system.
