摘要: 三维矿床建模技术是数字矿山的核心技术之一。结合三维矿体建模理论,建立阿舍勒铜矿矿体的实体模型,利用普通克里金方法进行品位分布与赋存资源储量估算。获得了矿体品位的普通克里金估值球状模型,并建立了三维品位模型。结果表明,建立的模型准确反映矿体的空间形态与品位分布,为后期进一步资源开发提供了数学模型。

Abstract: 3D ore deposit modeling is one of the core techniques for digital mine. Combining with the theory of the 3D ore-body modeling,an ore-body solid model on Ashele copper deposit is established,and then the ordinary kriging method is applied to estimate the reserves and grade distribution of ore-body.Finally,the spherical model for ordinary kriging estimation is obtained and 3D grade model of ore-body is established.The results indicated that the established model can accurately reflect the spatial and grade distribution of ore-body.It gives a mathematics model for further exploitation of mineral resources.
