摘要
海底矿产资源技术经济评价研究是当前我国国际海底资源开发工作中必不可少的重要内容。本文针对海底矿产资源及其开发利用技术现状,基于折现现金流量法,建立了适合我国的海底矿产资源开发技术经济评价模型。并利用该评价模型针对具体项目进行了实例评价分析,结果表明海底矿产资源开发项目具有投资大、收益高、高回报率的特点。进一步的敏感性分析表明:对经济效益影响最大的因素依次为矿石产量、矿石品位和金属价格。
The technical and economic evaluation of seabed mineral resources is an important part for exploitation of seabed mineral resources in China. Considering the present seabed mineral resources exploitation and utilization technology, in this paper a technical and economic evaluation model of seabed mineral resources exploitation is established based on discounted cash flow method. An example of the evaluation is given, the results show that lhe seabed mineral resources exploitation project has the characteristics of large investment,high income and high rate of return. Sensitivity analysis shows that the major impact factors on the economic benefit are as follows ： annual mine output,ore grade and ore price.
