Dimine软件在金川矿区24^(#)主矿体生产探矿中的应用

Application of Dimine Software in Production and Prospecting of 24^(#)Main Orebody in Jinchuan Mining Area

金川铜镍矿区富矿资源面临枯竭,导致贫矿产量扩大、矿石综合品位逐渐降低,亟需寻找富矿、特富矿资源。采用小型钻探工程对金川铜镍硫化物矿床24^(#)主矿体东延深边部富矿体的规模及形态进行控制,并利用Dimine矿业软件建立三维矿体模型,通过距离幂次反比法进行储量估算。结果表明,24^(#)主矿体东延探矿区段矿石资源量约4.7万t,镍综合品位1.06%,铜综合品位0.68%,镍、铜金属量分别为504、325 t。Dimine矿业软件实现了地质勘探数据库的集成化、可视化,为现代化矿山生产探矿提供了新的思路。

With the depletion of rich mineral resources in the Jinchuan copper-nickel mining area,the expansion of poor ore production,and the gradual decline of the comprehensive grade of ore,it is urgent to find rich ore and extra-rich mineral resources.The scale and morphology of the rich ore body in the eastern extension of the Jinchuan copper-nickel sulphide deposit 24^(#)were controlled by small-scale drilling engineering,and the three-dimensional ore body model was established by Dimine mining software,and the reserves were estimated by the inverse distance weighting method.The results show that the ore resources of the east extension exploration section of the main orebody of 24^(#)are about 47,000 t,the comprehensive grade of nickel is 1.06%,the comprehensive grade of copper is 0.68%,and the nickel and copper metal contents are 504 t and 325 t respectively.Dimine mining software realizes the integration and visualization of geological exploration database,providing new ideas for modern mine production prospecting.
