基于三维矿床模型的湖南某铅锌矿储量动态管理研究

Study on the reserves dynamic management of a lead-zinc mine in Hunan based on three-dimension deposit model

基于DIMINE2012数字矿山软件,本文介绍了某铅锌矿的三维矿体模型的建立过程,并在此基础上创建块段模型,采用距离幂次反比法进行品位空间插值,同时赋以该矿区的地质属性,最后形成该矿的资源模型。通过该模型,本文快速定位出了在165~173勘探线之间,埋深介于-110^-310m中段为该矿区铅锌矿的主要富集空间,在-190m中段矿石平均品位达到最高值,其结果准确地反映了矿床品位空间分布情况及其规律。因此,综合考虑当前市场产品价格,成产成本等因素,求取矿床工业品位,并设置对应的条件约束资源模型,即可快速地统计当前条件下的矿床储量,从而实现储量动态管理。

Basing on the DIMINE2012 software,this paper introduces the 3Dore model building process of some lead-zincmine,the empty block model was built base on the method,whose properties were filled using IDW for grade and directly write for others.Finally all of this data constructs the resource model.In this paper,the lead-zinc mine enrichment areas would be located quickly according to the model that those enrichment areas locate at prospecting line from 165to 173,and bury at level from-110mto-310m,the average grade reaches the maximum values at-190mlevel,the result reflected the grade spatial distribution principle.So considering price,cost and other factors to calculate industrial grade,then setting relevant prerequisites to constraint resource model,thus it can calculate the reserve of ore-body fleetly to achieve the actual supervision of minerals reserve.
