Status of Sustainability Development of Deep-Sea Mining Activities

With technological improvement such as ore exploration, robotics, and hydrodynamic lifting, deep-sea mining has attracted more attention from governments, companies, and scientific research institutions. Although its research and development has made great progress, there are still many obstacles in its industrial development, such as environmental pollution and sustainability development issues. This article analyses the research status of the sustainable development of deep-sea mining from an overall perspective. Through a literature review, this paper also discusses the application of the full life cycle assessment method to analyze environmental impact during the entire process of deep-sea mining ore application. Overall, this paper summarizes the research gaps that exist in the sustainable development of deep-sea mining, including the lack of sufficient quantitative research, environmental baseline data research, cumulative environmental impact assessment, resource recycling technology, and acceptable environmental impact range analysis. The significance of this article is to point out the most urgent problems to be solved in the research direction of the sustainable development of deep-sea mining in current academic circles. It has far-reaching potential to promote the industrialization process of the entire deep-sea mining industry.
