摘　　要：随着我国加入CRIRSCO的快速推进,未来我国矿产资源项目将会越来越多的直接参与到国际资本市场中,对矿产勘查各环节的定量化研究和评价是必然趋势。矿山岩心样品加工又称为试样制备,是矿产资源项目获取勘查信息的重要环节,其加工质量直接影响化验分析结果。目前我国现行实验室样品加工规范仅列出一般性加工工序,使用切乔特经验公式进行样品加工缩分,存在无法对样品加工流程误差进行定量化评价的缺点。本次研究使用Gy采样理论对某铅锌矿山的样品加工流程进行定量化研究,并据此优化设计矿山岩心样品加工流程。本次对岩心样品加工流程的定量化设计对我国矿产勘查过程中样品加工流程的定量化研究和设计具有重要参考意义。As long as China is pushing forward to become a member of CRISCO,the quantitative analysis of all exploration process is quite necessary.Sample preparation is the key process to get the mineral information of a mineral project,and the quality of sample preparation is highly related to the project risk.In China,most of sample preparation protocols are base on the Qeqott formula,which is recommended by industry specifications.In this paper,we designed a sample preparation protocol for a Zn mine based on Gy’s theory of sampling.This application of Gy’s theory of sampling is a significate example of optimizing the process of sample preparation.
