The Hunan Province in Central China has made notable strides in the development of crucial equipment and technology for deep-sea mineral resource exploration. Through a major scientific project, the province has successfully bridged international gaps in this field. A standout accomplishment is the creation of the world’s first intelligent electric deep-sea heavy-duty mining vehicle platform, as detailed in media reports on Tuesday.
The research team focused on exploring mineral resources at depths ranging from 3,000 to 6,000 meters. They have achieved significant progress in two essential equipment technologies: deep-sea mineral resources exploration equipment and equipment for collection and transportation. These advancements were made possible with the support of three common technologies: digital simulation, all-electric drive, and intelligent control, according to the Xinhua News Agency.
The project has also led to the development of a range of innovative equipment, including multi-point mobile drilling and sampling equipment. These advancements represent breakthroughs in 14 new technologies, with a total of 94 patents applied for, of which 45 have already been approved.
Lack of key equipment technologies has hindered deep-sea mining. Strict environmental protection standards and the unsuitability of existing mature land-based mining equipment have presented significant challenges. Additionally, the high pressure and salinity of deep-sea water, along with complex ocean currents, have rendered mineral exploration, mining, collection, and transportation operations extremely challenging.
The first phase of the project focused on key technology research and system prototype development, as well as field testing of some prototypes. The second phase involved integration testing and demonstration of various systems and equipment for deep-sea mining, as well as field testing of the entire system. The ultimate goal is to establish a complete chain of products for deep-sea exploration, mining, collection, and transmission, ultimately leading to the commercial exploitation of deep-sea mineral resources.
Reports indicate that an expert group responsible for review and quality control has affirmed that the project’s results have elevated the scientific and technological status of Hunan in the field of deep-sea mineral resources development. This achievement is expected to play a crucial role in advancing the industry in China. The project was jointly spearheaded by Hunan University and the Changsha Research Institute of Mining and Metallurgy, under the leadership of Ding Rongjun, an academician of the Chinese Academy of Engineering.
These breakthroughs in deep-sea mineral exploration represent a significant milestone for China’s technological advancements, emphasizing the country’s commitment to innovation and scientific progress. The achievements in Hunan Province pave the way for the responsible and sustainable exploitation of deep-sea mineral resources, which will undoubtedly have far-reaching implications for the global mining industry.
