摘要
Abstract
In order to accurately depict the 3D shape of ore body in a stope of sandstone type uranium mine and estimate the amount of resources,a 3D model of uranium body in the stope was constructed,and the amount of uranium resources was estimated by geostatistics method.Based on the drilling data of a sandstone-type uranium ore,Micromine software was used to build a drilling database by data statistical analysis,verification and correction.According to the specifications for sandstone type uranium deposits,a three-dimensional model of an in-situ leachable uranium deposit in a certain mining site was delineated with sample length combination,specific value processing,and square meter uranium quantity calculation,and presented the orebody with three-dimensional visualization.By setting relevant parameters,a variation function model was established,and ordinary Kriging method was used to interpolate uranium grade and estimate uranium resources.This study can clearly display the variation characteristics of ore body morphology,scale,grade,thickness and other parameters in three-dimensional space,which overcomes the shortcomings of traditional resource estimation methods and provides data support for digital mining well construction.关键词
