摘　　要：依据图日哥金矿地质勘探资料,借助于3DMine软件,建立了矿区的地质数据库,在此基础上建立了矿体三维地质模型,更加真实的展示了矿体的三维空间形态,依据地质统计学原理,筛选出样品进行特高品位处理、样品组合等,依据组合样品的统计分布特征,建立了矿体走向、倾向、垂向等三个方向的变异函数模型,利用普通克里格法对块体模型进行估值,最终计算出矿区内9条金矿体的储量。结果表明,该方法精度较高,可为矿山在今后的资源动态监测及矿山管理中提供重要的理论依据。According to the geological exploration data of TuRiGe gold deposit,the geological database of mining area is established with the aid of 3DMine software.The 3D geological model of ore body is established,and the 3d spatial shape of ore body is displayed.According to the statistical distribution characteristics of composite samples,the variation function model of ore body direction,tendency and vertical direction is established.the general kriging method is used to estimate the block model,and the reserves of 9 gold orebodies in the mining area are calculated.The results show that the method has high precision and can provide an important theoretical basis for the future resource dynamic monitoring and mine management.
