根据一个矿体的数学模型可以了解到块段的真实品位,所模拟的矿体其样品品位是正态分布的,并具有与球状半变异函数模型相适应的空间相关关系。在该模型矿床上将真值与矿床采样所得到的克瑞吉(Krige)估算值和多边形估算值加以对比,可以证明克瑞吉法要比多边形法更为优越。最后,根据估算值来选择矿床块段的结果表明:如果采用克瑞吉法,所预测的块段大部分是可采出的;而如果采用多边形法,则可能会产生很大的偏差,偏差的大小取决于边界品位的位置。
According to the mathematical model of an ore body, the true grade of the block can be obtained. The sample grade of the simulated ore body is normally distributed, and has the spatial correlation suitable to the spherical semi-variogram model. Comparing the Krige estimate with the polygon estimate from the mineralized deposit on the model deposit can prove that the Creeping method is superior to the polygon method. Finally, the results of selecting block segments based on the estimated values show that most of the predicted block segments are recoverable if using the Kriging method, while the polygon method may produce large deviations and deviations The size depends on the location of the border grade.
