中文摘要：

全面论述了近30年来国内外深海采矿垂直管道水力提升技术的发展和研究现状，对十几个国家深海采矿垂直管道水力提升系统进行了描述和分析，重点介绍了我国深海采矿垂直管道水力提升技术的研究成果。从管道输送安全角度考虑，论述了垂直管道堵塞的关键问题和解决措施，可为我国深海多金属结核、富钴结壳和热液硫化物等金属矿产资源垂直管道水力提升技术的研究提供参考。

英文摘要：

The development of hydraulic lifting technique with vertical pipeline for deep-sea mining in the past nearly 30 years, as well as the status quo was comprehensively discussed. Compared with those hydraulic lifting system with vertical pipeline used for deep-sea mining in several foreign countries, the great achievement China has made in hydraulic lifting technique for deep-sea mining was introduced in details. In view of the safety of pipeline transportation, the concerned blockage problem in vertical pipe and its proper solving measures were all discussed, which can provide reference for the future development in hydraulic lifting technique for the mining of China＇s deep-sea polymetallic nodules, rich cobalt crust and hydrothermal sulfide.
