Boundary Analysis and Delineation of Mineral Resource Estimate Domains
摘要
Abstract
Mineral resource estimation is usually carried out in specific estimate domains,and the boundary conditions of these domains have a signifi-cant effect on the evaluation results. The traditional method adopts the hard boundary condition that uses the industrial indicators to delineate ore body and performs subsequent estimation. This traditional way of estimation places emphasis too much on the economy of the deposit but attaches less importance to the geological and geostatistical features of the deposit. This paper introduces the concepts of mineral resource estimate domains and the boundary analysis methods and discusses their application in the estimation of resource through practical cases. On this basis, the basic principle to use three-dimensional software to delineate the estimate domains is proposed. The practices show that the using soft boundary constraints or delineation of mineralization domains for grade estimation may be more in line with the requirements of the estimation of mineral resources in the early exploration stage,thus reducing the valua-tion risk of boundary uncertainty of estimate domains.关键词
