摘要
任何固体矿产只有经过系统的勘查、严谨的资源储量估算才能被认可。估算方法选择是否切合实际、相关参数选择是否合理严重影响勘查报告的编制质量和对矿产资源的如实评价。该文以柴家沟大型斑岩型钼矿勘探报告为例,将资源储量估算方法和参数选择的经验与从业者交流分享。对工业指标、方法选择及依据、主要估算参数确定等内容进行了阐述,强调了单矿层平均品位、厚度的计算过程,细化了特高品位确定和处理方法,为同类型矿床资源储量估算提供借鉴。
Only through systematic exploration and rigorous resource reserve estimation can any solid mineral be recognized by the world. Whether the selection of estimation methods is practical and whether the selection of relevant parameters is reasonable seriously affects the quality of exploration report and the true evaluation of ore resources.Taking the exploration report of Chaijiagou large porphyry molybdenum mine as an example,this paper shares the experience of resource reserve estimation method and parameter selection with practitioners.This paper expounds the industrial index,method selection and basis,determination of main estimation parameters,etc.Emphasizes the calculation process of average grade and thickness of single ore bed,specifies the determination and treatment method of ultra-high grade,so as to provide reference for resource reserve estimation of the same type of deposit.
