摘要
运用SD法对几内亚3650号矿区部分矿段铝土矿资源量进行估算,并对其资源量的可靠性进行评价。SD法与地质块段法计算结果对比显示,矿体各主要参数的相对误差均在合理范围内,其差异产生的原因主要有单工程圏矿方式、矿体边界的确定方法、矿体品位厚度计算方式等。
In this paper,the authors estimate part of reserves of orebody in No.3650 bauxite in Guinea by SD method,and evaluate the reliability of SD resource. According to the calculation results of SD method and geological block method,the relative errors of major parameters of orebody vary in a reasonable scope. The differences mainly reason from three aspects of a single engineering confirming orebody,ore boundary determination and the grade and thickness calculation of orebody.
