西太平洋拉蒙特平顶海山富钴结壳矿区圈定与资源量估算

摘要

In order to define reasonable and preferable mine area for oceanic Co-rich crust mine application,a new method of man-machine interactive mining delineation is put forward based on the model of mining selection which was proposed through the International Seabed Authority(ISBA),as well as the crusts distribution of Pacific sea-mount and the parameter index of mine delineation.Besides,the prospective areas of Lamont Guyot crusts re-sources and 51 crust blocks which meet regulations about blocks required by ISBA are delineated based on the sur-veying data of Co-rich crust resources on Lamont Guyot by means of dredge hauling ,the amount of Co-rich crust and metal are estimated.Finally,by analyzing the location of areas 51 blocks in this guyot applied by Japan in 2013,it is indicated that the results of the man-machine interactive mining delineation method is more unanimous with the goal of mining delineation of crusts resource.It provides a new method for oceanic crust cobalt-rich mine application.%为能科学合理、快速量化地圈定出大洋海山钴结壳优质矿区，本文基于国际海底管理局提出的矿区选取模型，利用我国西太平洋海山钴结壳资源调查的拖网采样资料，结合西太平洋海山钴结壳分布特征，提出人机交互式的矿区圈定方法，对西太平洋马尔库斯－威克海山区拉蒙特平顶海山圈定出钴结壳资源远景区和符合国际海底管理局规章要求的51个钴结壳矿块，估算出拉蒙特平顶海山和51个矿块的钴结壳资源量及金属量，同时通过对拉蒙特平顶海山日本申请矿区的结壳资源分布特征分析，表明采用人机交互式的矿区圈定方法得出的结果，不仅能快速定量地圈定出钴结壳资源前景较好的矿区，也为大洋海山钴结壳矿区圈定和资源量估算提供了新方法。
