摘　　要：阐述了西岔金矿体的普通克里格法可视化储量计算步骤和计算流程,通过用不同颜色来表示矿体内晶胞的不同品位,直观地展现矿体内部品位分布情况,实现了西岔金矿普通克里格法的三维可视化储量计算。结果表明,预测储量在误差允许的范围之内,预测结果较为理想。The procedures and flow process of visualized reserves computation by using Krige method for the minerals in Xicha Gold Mine are described. Different colors are used to present different grades of crystallites in the minerals. The distribution of their internal grades is visually represented, by which 3D visualized reserves computation is implemented in Xicha Gold Mine by using Krige method. The result shows that the error of predicted reserves is within the allowable range, the predicted result is more ideal.
