摘要:
我国自20世纪50年代就开始了近海的地质调查及区域填图工作,80年代起在近岸水域进行了针对重砂矿的相关调查研究,90年代中后期,随着区域经济的迅速发展,近岸建筑用海砂矿产的勘查工作迅速兴起,形成了遍布我国海岸线的几十个矿区。自2004年起,在我国近海海域根据资源分布状况圈定了9个潜力区块,实施近海海砂及相关资源潜力调查。分析我国近海海砂勘查评价与开发现状及面临的主要问题,提出了我国近海海域建筑用海砂开发利用亟待解决的基础性工作及建议,以对我国近海建筑用海砂矿产调查、评价及开发有所裨益。
Abstract:
In China offshore, the geological survey of marine sediments started in 1950s, and henceforth refined the degree of survey gradually. In 1980s, the solid mineral resources, mainly heavy minerals, were investigated in some parts of China sea areas. From late 1990s, the survey of marine sand for construction commenced rapidly. The marine sand resources greatly support the development of local construction. Meanwhile, owing to the lack of rules and standards related to the exploration and exploitation of marine sand, we discussed the present situation of the lacking and gave some advice to the exploration and exploitation of marine sand.
