Abstract
This paper describes of three things. First, the Kriging estimation on gold grade which
is distributed in the vein. The empirical variogram method based on Matheron classical
and robust of Cressie-Hawkins. The two empirical fitting on variogram theory of
spherical and exponential equations of weighted least squares and ordinary least
squares used. The predictions of six sizes block-Kriging respectively, 15×15, 25×25,
35×35, 50×50, 75×75 and 100×100 based on four variographic models. Second,
determine the priority of 24 prediction combinations based on TOPSIS method. Finally,
the multiple criterion decision making method namely, 15×15 block Kriging based on
a robust empirical variogram of exponential weighted least squares model represents
as the best result.
