摘要
选取申请区块内富钴结壳平均厚度、平均品位、矿区面积、平均坡度、平均水深和申请区块中的有效站位数等6个因素作为申请区块优劣性评判的指标,将申请区块的优劣性分为3级,建立了富钴结壳申请区块优劣性的模糊评判方法,并进行了实例研究。评判结果对于进行富钴结壳申请区块的优选提供基础。根据模糊评判结果与资源量大小排序两种区块保留结果中部分申请区块存在不一致,建议在后期对申请区块放弃工作时同时考虑模糊评判结果和资源量大小。研究结果可以为将来富钴结壳申请区块的放弃工作提供技术储备。
In order to selecting the best applied blocks of cobalt-rich crust,the fuzzy method was used.The average thick,the average percent of cobalt,the ore field area,the average slope,the average water depth and the number of valid stations were selected as the indexes for deciding the quality of the applied blocks of cobalt-rich crust,and the quality of the applied blocks of cobalt-rich crust was divided into three classes,and the fuzzy evaluation model was setting,then an instance was done.The result could be fundamental for selecting the best applied blocks of cobalt-rich crust.The fuzzy evaluation results were inconsistent with the resource quantities for some applied blocks of cobalt-rich crust,so both of them should be considered when the applied blocks of cobalt-rich crust were selected.The result would benefit the selection of the applied blocks of cobalt-rich crust in the future.
