Deep-sea seabed multi-metal nodule low-disturbance mining system

Abstract

The invention discloses a deep-sea seabed multi-metal nodule low-disturbance mining system. The deep-sea seabed multi-metal nodule low-disturbance mining system comprises a mother ship, an ore concentration station, an ore lifting system and mining devices; the mother ship is located on the sea surface, the ore concentration station and the mining devices are located on the seabed, the mother ship is connected with the ore concentration station, the ore lifting system and the mining devices through umbilical cables, and power supply and communication of the ore concentration station, the ore lifting system and the mining devices are achieved; the ore concentration station is connected with the mining devices through communication power supply cables; and the mining devices are used for collecting ore along the seabed and then pouring the ore into the ore concentration station, the ore concentration station is provided with a container for containing the ore, and the container can be lifted to the mother ship on the sea surface through the ore lifting system. The multiple mining devices are arranged, can work in a designated area in parallel, do not interfere with one another and are high in mining efficiency. The mining devices are small in size, posture control is conducted through propellers, disturbance to the seabed environment is small, and damage to the seabed environment is small.

Description

technical field [0001] The invention belongs to the technical field of marine mining engineering, and in particular relates to a low-disturbance mining system for polymetallic nodule deposits on the deep seabed. Background technique [0002] In recent years, with the increase of human demand for metal resources and the acceleration of the consumption of terrestrial mineral resources, people have focused their attention on the underdeveloped seabed mineral resources. Since the resources of the high seas belong to all human beings, according to the provisions of the United Nations Convention on the Law of the Sea, "the right to develop resources usually follows the principle of whoever develops first." Countries all over the world attach great importance to the sustainable and green development of seabed mineral resources. The polymetallic nodules located on the seabed are precious ores that look like potatoes, and their diameters are usually between 5 and 10 cm, most of which...

Problems solved by technology

[0004] Some marine experts and scholars mentioned that the above-mentioned existing technologies not only agitated the sediments on a large scale during the process of collecting minerals, but also transferred the marine organisms living on the polymetallic nodule ores, destroying the habitats they created for hundreds of years , causing great and irreparable damage to the seabed ecosystem
