摘要

摘要: 通过对各种矿区圈定数据的分析,运用地理信息系统(GIS)建立了地形、品位、厚度和矿区的多维数据模型,并根据国际海底管理局提出的矿区选取模型对某海山进行了矿区圈定,给出了一种矿区圈定结果,提出了矿区圈定优劣性评价参数并对结果进行了评价.研究结果表明,受数据量的限制,数据模型的效果不是非常理想,有必要结合地球物理数据进一步研究;在相同的勘探条件下,应用小块段模型比应用大块段模型可以获得更优的资源远景区;富钴结壳连续矿区中的斑状空白只有在面积大于一定值时才会对块段的放置和数量产生影响.

Abstract: The ore area delineation is the aim of cobaltrich crustresearch because it is related to the economic benefit of countries. After analyzing all kinds of data about cobaltrich crust, the models of terrain, abundance, thickness and diggings are established using GIS. Orear eas are delineated using the prescriptive models which are brought forward by the International Seabed Authority, and one of the results is stated. Parameter, which can indicates the result is better or not, is also discussed. The results show that the data models are not perfect because of the limitation of data, and more researches should be done comb-i ning the geophysical data. In the same prospecting condition, the small block model is better than the big block model. The spot areas, where there are nocobal-trich crusts or cobaltrich crusts cannot formore, can influence the placement and amount of oreblocks only when their areas are more than some value.
