Key points
- The annual seminar of the NSFC key project on deep-sea mining system response mechanisms was held at Xiangtan University on December 23.
- The project is led by CRIMM with Minzu University of China and Xiangtan University, chaired by Professor Jin Xing.
- Reports covered deep-sea mining system dynamic behavior and hose transport of metal nodules.
- Participants set objectives, priorities and cooperation directions for follow-up work.
On December 23, the annual seminar of the National Natural Science Foundation of China (NSFC) key project “Research on the Response Mechanisms of Deep-Sea Metal Mineral Resource Mining Systems to Complex Working Environments,” organized under the leadership of Changsha Research Institute of Mining and Metallurgy (CRIMM) and undertaken jointly with Minzu University of China and Xiangtan University, was successfully held at Xiangtan University.
The meeting was hosted by Xiangtan University’s College of Civil Engineering and Mechanics. Attendees included Professor Jin Xing, chief engineer of CRIMM’s Marine Institute and the person responsible for COMRA’s 12th Five-Year Plan ocean projects, an 863 program project, and the NSFC key project; Professor Xia Jianxin of Minzu University of China, a national-level selectee of the New Century Hundred-Thousand-Ten Thousand Talents Program and the principal investigator of the NSFC key project; Associate Professor Maciej of the Institute of Environmental Engineering at Wroclaw University in Poland; Professor Guo Xiaogang of Xiangtan University; and core members of the NSFC key project.
The project leader, Professor Jin Xing, chaired the meeting, which was held in two stages. In the first stage, research progress reports were given around the theme of “system dynamic behavior.” Associate Professor Deng Xuhui, on behalf of the Xiangtan University team, presented a report titled “Research on the Dynamic Behavior of Deep-Sea Mining Systems”; Professor Xia Jianxin presented “Research on the Dynamic Behavior of Hose Transport of Metal Nodules”; and Professor Guo Xiaogang presented “Research Trends on Catenary Lines under Concentrated Forces,” among other reports. In the second stage, the participants held lively discussions on key issues in deep-sea mining. The attending experts reached consensus on the objectives, content, research priorities, and directions of cooperation for the follow-up work, laying a good foundation for advancing the later stages of the project.
The successful holding of this NSFC key project seminar pointed out the direction and priorities for completing the project’s research, and further clarified the entry points for follow-up cooperation and the approaches for solving difficult problems.
