Abstract

RONDON, O.. On localizing uniform conditioning estimates. J. S. Afr. Inst. Min. Metall. [online]. 2014, vol.114, n.8, pp. 639-645. ISSN 2411-9717.

SYNOPSIS Localized uniform conditioning is a technique developed to spatially locate selective mining unit grades that have been derived using uniform conditioning for the assessment of recoverable resources. The technique has the advantage of producing selective mining unit estimates conforming to the uniform conditioning panel-specific grade-tonnage curve while introducing spatial information at the scale of the selective mining units. This paper describes an alternative technique to localized uniform conditioning which does not explicitly require the uniform conditioning panel-specific grade-tonnage curve to localize the selective mining unit estimates. The technique can therefore be implemented in mining software where uniform conditioning is not available.

Keywords : uniform conditioning; recoverable resources; change of support; localized UC; Gaussian distribution.
