DIMINE软件在云南鹤庆北衙金多金属矿山的应用

APPLICATION OF DIMINE SOFTWARE IN BEIYA GOLD POLYMETALLIC MINE IN HEQING,YUNNAN

本文以鹤庆北衙金矿区为例,利用DIMINE软件建立矿区地质数据库、地形三维模型、矿区相关地质体模型、矿体模型和块段模型。依据前人成矿规律及矿床类型总结,充分考虑历年剥采矿体实际形态、探采对比、近期成矿规律新认识的基础上,建立了五种类型矿体实体模型:残坡积型、产于富碱斑岩与碳酸盐接触带矽卡岩型、构造破碎带型、硅钙面型、脉型。块体模型建模思路:空块段模型建立-样品数据处理-品位估值-块段赋值。实现了地质体及矿体的可视化及资源的快速估算,为矿山开采规划建立了数据平台,进一步精准指导采矿,较好的服务指导生产。

Taking the Beiya Gold Mine in Heqing as an example,the DIMINE software was used to establish the geological database,the three-dimensional terrain model,the relevant geological body model,the ore body model and the block modelof the mining area in this paper.Based on the summary of ore-forming regularities and ore deposit types,and taking full account of the actual shape and comparison of exploration and mining of ore bodies stripped over the years,as well as the new understanding ofmetallogenic regularity,models of five types ore bodies have been established,includingeluvial-deluvial type,skarn type occurring in the contact zone between alkali-rich porphyry and carbonate,structural fracture zone type,silicon-calcium surface type,and vein type.The block model modeling method is empty block model establishment-sample data processing-grade estimation-block assignment.The research results enable therealization of visualization of geological body and ore body and the rapid estimation of resources,andprovide a data platform for mining planning,which is helpful forfurther precise miningguidance and production.
