Abstract: With the increasing depletion of global land resources, deep-sea polymetallic nodules, as a potential and abundant mineral resource, have attracted widespread international attention. This paper systematically elaborates on the operational process and equipment composition of deep-sea polymetallic nodule mining, reviews the progress of domestic and foreign experimental activities in the field of deep-sea polymetallic nodule mining, and focuses on sorting out the key equipment and technologies applied or developed globally in aspects such as deep-sea mining platforms, underwater collection systems, mineral lifting systems, and environmental monitoring systems. After analyzing the gap in the development of domestic equipment technology, this paper puts forward targeted suggestions, aiming to promote the development of China’s deep-sea polymetallic nodule mining equipment technology, in order to realize the development and utilization of deep-sea mineral resources.

Key words: deep-sea mining, polymetallic nodules, mining sea trial, mining equipment, technological development
