statistics half a century ago. We begin developing change-of-support models in their initial historical setting, which was in mining. 2.1 Classical presentation of change-of-support models Geostatistical change of support models have originally been setup to allow recoverable reserve esti …

Workshops Global Change-of-Support Background. Put simply, change-of-support in mining geostatistics refers to the derivation of the SMU-grade histogram from the sample-grade histogram. SMU stands for Selective Mining Unit and is commonly a small block relative to the drill spacing.

Jan 13, 2019 · With all change of support models, the distribution of SMU grades maintains the same mean while the variance is reduced by the variance correction factor from the average variogram. Historical Change of Support Models. The following change of support models are not recommended due to the strong assumptions required (Rossi & Deutsch, 2013).

Explicit geostatistical change-of-support models are useful to anticipate the deformation of statistical parameters as a function of support in the presence of auto-correlation. The discrete Gaussian model can be applied to data with different, non-point supports (Brown et al. 2008). Non-Gaussian (isofactorial) models are available.

Mar 14, 2008 · As a consequence, post-processing the local point-support grade distributions on the basis of the latter systematically understates the importance of the change of support at the local scale and makes selective mining appear more economically attractive than it really is.Cited by: 6
