中国大洋多金属结核集矿技术研究综述

我国大洋多金属结核开采的集矿技术研究始于20世纪90年代，是大洋多金属结核资源开发项目的重点研究课题之一。“八五”期间，在理论研究的基础上，研制出了2台试验集矿模型机，模型机的各项技术指标均达到了设计要求；建成了一座占地4000m^2的深海采矿综合实验室。“九五”期间，进行了扩大实验研究，研制出了中试集矿机，并在150m水深的湖中进行了综合湖试，取得了满意的结果。对我国十年来深海采矿集矿机技术的发展作了回顾，总结了攻关解决的一系列关键技术。

The Review of Development of Ocean Polymetallic Nodule Collecting Technique in China

In China, the research on the collecting technique for mining ocean polymetallic nodules, starting in 1990s, is one of major study subjects of the ocean polymetallic nodule exploration project. During the eighth five-year plan, based on theoretical studies, two model collectors were developed, of which the various technical indices had reached design requirements, and a complex laboratory for deep-sea mining had been constructed which covered a floor space of 4000 square meters. During the ninth five-year plan, the scale-up laboratory study was carried out, a pilot collector was developed, a complex experiment of the collector in the underwater at 150 m from the lake surface was conducted, with satisfactory results. This paper reviews the development of nodule collecting technique in deep-sea mining, and summarizes many key techniques resolved through tackling key problems in China during past ten years.
