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

Basing on the DIMINE²⁰¹² software,this paper introduces the 3D ore 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.
