摘要
利用三维地质体建模软件Minexplorer建立了西藏甲玛铜多金属矿床I-1-1夕卡岩矿体的三维模型并对其进行储量计算。利用矿山勘探过程中积累的钻孔数据,建立地质数据库,生成三维钻孔,通过剖面定义、单工程矿体圈定、剖面编辑、曲面连接、封装成体建立了I-1-1矿体的三维模型。分别使用普通克立格、距离倒数法、块段法和截面法对矿体的储量进行了计算并与生产所得储量数据进行对比。I-1-1矿体为第一勘查类型,采用截面法计算所得结果与之更为接近。
This paper builds the three dimensional model of I-1-1 skarn type ore body of the Jiama copper-polymetallic deposit and calculates the reserve of the deposit by Minexplorer software which is a three dimensional model building software.First,it builds the geological database using the drill data and demonstrates the drill holes in 3-D view.Then,after the process of profile definition,delineation of ore body in a single drill hole,edition of profiles,connection of surfaces,encapsulation of surfaces,it builds the ore body in three dimensions.It calculates the reserve of I-1-1 ore body by different methods,such as ordinary Kriging,ore block,inverse distance weighting and section.The results are compared with the real reserve produced by the production of the mine.Since this ore body belongs to the first exploration type,the result of the section method is close to the reserve of the ore body provided by the mine.
