中国大洋矿区采矿环境研究

STUDY ON MINING ENVIRONMENT IN CHINA'S OCEAN MINING AREA

深海采矿面对的是5000m左右水深的海底复杂环境和条件，把赋存于海底表层的多金属结核采集起来，并将其输送至海面采矿船上，需要考虑海水压力、腐蚀、海流冲击、海底地形、地质、矿床位置、海洋气象及海况等因素。本文从采矿工程角度对中国大洋矿区采矿环境进行分析研究。

Ocean mining at a depth of 5000 m faces complicated seabed environment and conditions. Inorder to collect the polymetallic nodules deposited on t he seabed and transport them to the mining vessel onthe water surface, many factors should be taken into account, including seawater pressure, corrosion, cur-rent impact, seabed topography and geology, deposit location, ocean meteorology, oceanic condition, etc.From the viewpoint of mining engineering, this paper deals with the mining environment in China's oceanmining area.
