Description

Technical Field

[0001] The present invention relates to the technical field of deep sea mining, and in particular to a deep sea mining plume suppression technology using an AUV to add a flocculant. Background Art

[0002] Deep-sea polymetallic nodules contain rich strategic metal resources such as manganese, cobalt, and nickel, and have immeasurable commercial and strategic value. Polymetallic nodule mining often uses seabed ore collection vehicles for jet collection. The jet process will destroy the original structure of deep-sea sparse and soft sediments and stimulate the suspension of particles to form plumes. Once formed, the plume can spread for tens of kilometers on the seabed and remain suspended for several months, posing a huge threat to the survival of deep-sea organisms. Turbid plumes can also interfere with the use of optical equipment on deep-sea mining vehicles and affect normal mining operations.

[0003] The use of flocculants can accelerate the flocculation of plume particles and promote the rapid sedimentation of plumes. However, due to the relatively closed deep-sea environment, it is difficult for mining vehicles equipped with flocculants to meet long-term operation needs. Autonomous underwater vehicles (AUVs), as an intelligent and efficient underwater operation platform, provide a new solution. By using AUVs to accurately add flocculants to deep-sea mining vehicles, the aggregation and sedimentation of suspended particles can be effectively promoted, and the formation and diffusion of plumes can be suppressed from the source.
