DATE:  23 April 2015
VENUE:  Glen Hove Conferencing,

COST: R2 451.75 + VAT


With the advent of many new or smaller coal mines, and increased requirements for Eskom, export and local industries, the need arises to produce larger quantities of coals for the market place by combining together products from different sources, in one form or another.  This can be successful or disastrous.  This course seeks to outline the fundamental issues, potentials, and principles and practices of successful mixing and/or blending for the market place. 


•    To outline the in depth nature of coals

•    To understand issues with different seams

•    To consider the difference in blending or mixing

•    To understand the impacts thereof - the good and the bad...

•    To establish what component is compatible and what is not.

·         To define additive and non-additive coal qualities and parameters and link that to the properties /characteristics of a mixed coal and its behavior during utilisation.

•              The behavior of Coal Blends/Homogenised Coal/Mixed Coal

•              Question and Answer Session

Session 4

•              Tests proving compatibility of blends – or not

•              Reports from users

Gerhard Esterhuizen graduated from the University of the Free State with a B.Sc. (Geology) and B.Sc. (Hon. Energy Studies) from the University of Johannesburg and has spent some 28 years with Sasol Mining in the Geology Department and Strategic Capacity Management Department.  He was responsible for the management of Coal Exploration Programmes, new business development and the training and development of geological personnel and has written many technical training manuals.  During 2002 he entered the private sector as an Independent Consulting Geologist and has managed various Exploration Programmes on behalf of local and international Exploration and Mining Companies and State Enterprises in southern Africa.  He is a coal specialist and advises companies on the development of Exploration Business Plans, management of the Exploration Programmes, potential utilisation of the coal products and risk analyses.  Quality assurance and quality control procedures and techniques to apply are not always well-understood by many dealing with coal and Gerhard has assisted many companies to employ Best Practice and to perform work to set standards.  He has represented companies as a Technical Expert in a court of law to resolve disputes and is a guest or visiting lecturer at the University of the Witwatersrand since 1992.  Gerhard has also presented many national and international papers at conferences on various topics.  He is currently writing a text book aimed at the southern African coal geologist to facilitate a better understanding of the Coal Exploration Business and the integration with sound Mining-Geological Practices.
