1前言在过去的30年间，国际上已开发和试验了多种采矿系统。目前国际上公认最有实用价值的是流体提升采矿系统。其原理是通过一根垂直提升管道借助流体上升动力将海底集矿机采集的结核矿石提升到海面采矿船上。该系统可配用自行式遥控集矿机，它具有较好的灵活性，能达到较高的 1 Introduction In the past 30 years, a variety of mining systems have been developed and tested internationally. At present, internationally recognized as the most practical value is fluid upgrading mining system. The principle is to raise the nodule ores collected by the subsea concentrator to the surface mining vessel by means of a fluid rising power through a vertical lifting pipe. The system can be equipped with self-propelled remote collectors, it has better flexibility, to achieve higher
