【摘要】 对海山富钴结壳的圈矿方法进行了分析和探讨,指出海山富钴结壳圈矿的主要方法和步骤为:(1)挑选富钴结壳发育良好的海山。除大片连续厚层板状分布的结壳发育良好的大型平顶海山是重点调查的目标海山外,规模较小的尖顶海山是近年来新的圈矿目标海山。(2)确定矿块的边界位置。对选定的海山进行深海摄像、电视抓斗、拖网和浅钻等多种手段的调查,通过所取得的综合结果对矿块边界进行判断,确定准确的矿块边界。(3)计算结壳的覆盖率。利用调查所获得的矿块相关的数据和信息对矿块内结壳厚度和结壳覆盖率以及矿区资源量进行评估。更多还原

【Abstract】 Base on the new trends of ISB(International Seabed Bureau) and advance in our investigation of Co-rich crusts(hereafter for short as crusts) in the Northwest Pacific,this article discusses a method for finding the ore block of crusts on seamounts.The authors think that it is important to select the seamount,where the crusts develop well so that we can get twice the result with half the effort,then to determine the positions of the ore blocks, the depths of crusts and its percentage of coverage.Thus the adequate quality ore blocks can be found out on the selected seamount.更多还原
