Micromine软件在某金矿床资源储量估算中的应用

Application of Micromine in resource reserve estimation of a gold deposit

本文以吉林省白山市某金矿床地质勘查资料为基础,通过收集钻孔、测量等数据信息,建立了Micromine地质数据库,根据资料信息利用Micromine软件建立矿体三维实体模型,通过变异函数计算和拟合确定搜索椭球体的最佳计算方向,采用普通克里格法对金矿体进行资源储量估算,并采用距离幂次反比法进行验证,验证结果表明本次资源储量估算采用的方法是合理的,结果是可靠的。

Based on the geological exploration data of a gold deposit in Baishan City,Jilin Province,the Micromine geological database is established by collecting drilling and surveying data.According to the information,the 3D solid model of ore body is established by using Micromine software,and the best calculation direction of searching ellipsoid is determined through the calculation and fitting of variation function,and the common Kriging method is used for the resources reserve estimation of gold ore body,which is verified by the inverse ratio method of distance power.The verification results show that the method used in this resource reserve estimation is reasonable and the results are reliable.
