Abstract: Deep-sea mineral resources are globally recognized strategic resources.With the rapid progress of modern science and technology, commercial mining era of deep-sea mineral resources is about to come.Therefore, it’s very urgent and necessary to strengthen the exploitation of deep-sea mineral resources, to accelerate the pace of commercial development.This paper discusses the deep-sea mineral resources development technology, equipment requirements and the technology innovation, innovation resources, major equipment, and the industrial chain of deep-sea mineral resources in China using comparative analysis and by offering examples.The results show that there are three aspects in the development of regional industry practice, including development of regional imbalances, lack of industry attention, technology of external dependence serious.This paper put forward some suggestions to promote the development of deep-sea mineral development technology in the aspects of the deep-sea mineral resources exploration, green mining, safety development existing in the technical bottleneck.
