Presentation on Kriging

Exploratory Data Analysis

Modern Sampling Theory and Methods

The Geostatistical Association of Southern Africa in conjunction with The School of Mining Engineering – University of the Witwatersrand is pleased to announce a 5 day short course on Modern Sampling Theory and Methods presented by Dr D.François-Bongarçon from 3 – 7 October 2011 at the  University of the Witwatersrand, Johannesburg

ABOUT THE COURSE

The objective of the course is to reach a modern understanding of the theory of sampling of particulate materials (such as crushed drill core and reverse circulation samples) and the practice, scope, limitations and appropriate applications of sampling.

The theory and practice of sampling of mineral particulate material have been the focus of continuous attention on part of the mining industry for more than a century. This is due to its paramount importance at all the stages of a mining project, from exploration to production.   Widely acclaimed and admirable works by Pierre Gy (from 1968 to 1982) have paradoxically met with limited success in low-grade types of mineralization, due to difficulties in the proper implementation of its variance prediction formula.  These difficulties have been addressed by the course instructor who has developed simple and effective tools for the practical implementation of Gy’s theory.

The course is accompanied with practical application exercises, and series of practical recommendations on equipment and methods, as well as practical implementation of techniques for the numerical control of sampling procedures.

†Group Consultant:  Geostatistics and Evaluation, Gold Fields Limited, Perth, Australia

A tribute to Professor D. G. Krige first appeared in the Proceedings of the APCOM 2003, but has been modified and updated to acknowledge the award for his distinguished contributions to engineering, by the United States National Academy of Engineering (NAE) Section 11, Earth Resources Engineering, in February 2010.

In recognition of Danie Krige’s distinguished contributions to engineering, he was elected a Foreign Associate of the United States National Academy of Engineering (NAE) Section 11, Earth Resources Engineering, in February 2010. The Induction Ceremony for the NAE Class of 2010 is to be held Sunday afternoon, 3 October, during the NAE Annual Meeting in Washington, DC. The Ceremony is the formal inauguration of the new Members and Foreign Associates into the Academy, and comes with an invitation to attend the Induction Ceremony and the public sessions of the Annual Meeting. Danie is the first South African to ever receive this award from the NAE.
