由中国五矿集团公司所属长沙矿冶研究院承担的国家“863”计划项目“深海多金属结核和富钴结壳采掘与输运关键技术及装备”的深海扬矿泵管输送系统海上试验,于近日在南海海域成功进行,并顺利通过海试专家组验收。这是我国首次开展深海采矿单体工程技术的海试,标志着我国深海矿物输送技术跻身世界一流水平。该项目自2012年实施以来,针对我国深海采矿系统中的关键技术研制出无堵塞多级离心泵 China Minmetals Corporation, a subsidiary of Changsha Research Institute of Mining and Metallurgy, undertakes the national “863” project and “deep sea pumped mine pipe transportation for deep sea polymetallic nodules and key technologies and equipment for mining and transporting cobalt-rich crusts” System marine test, successfully conducted in the South China Sea waters recently, and passed the acceptance test by the expert group of sea trial. This is the first time that China has conducted a sea trial of deep-sea mining monomer engineering technology, marking China’s deep-sea mineral transportation technology among the best in the world. Since its implementation in 2012, the project has developed a clog-free multistage centrifugal pump for key technologies in deep-sea mining systems in China
