Description

An environment-friendly submarine mineral resource development device and development method

technical field

The invention relates to the technical field of marine mining engineering, in particular to an environment-friendly seabed mineral resource development device and development method.

Background technique

Minerals are natural minerals and rocks that can be used by human beings and are non-renewable energy sources. With the continuous development of the economy and society, the consumption of minerals is increasing, and the resources on land are increasingly depleted. Public information shows that the seabed contains huge reserves of mineral resources, mainly distributed on the continental shelf. The effective exploitation of seabed mineral resources will help ease the pressure of onshore mineral exploitation and contribute to sustainable economic and social development. At present, companies such as Canada's Nautilus Mining Company and China's Shandong Gold Group Sanshandao Gold Mine have tried to mine seabed minerals. However, the biggest obstacle to the development of seabed mineral resources at present is that mining activities may damage the fragile seabed ecological environment. Under the influence of ocean currents and seabed water currents, the dust and sewage generated during the mining process are carried to dozens of nautical miles away, which not only pollutes the surrounding areas of the mining area. It is serious, and it is likely to spread the pollution of the seabed. More organizations and experts worry that once the dark and high-pressure seabed ecology is destroyed, the recovery period will be very long, and it is likely to cause ecological serial damage. In 2018, the European Parliament called for a ban on seabed mining until the environmental impact and threat to ecosystems of seabed mining activities are fully understood. my country's environmental protection experts also suggested that deep-sea mining should be banned in specific sea areas around the world. Humans cannot ignore the protection of the environment because of petty profits.
