Economic Coal Resources of the Highveld, Ermelo, South Rand and Sasolburg-vereeniging Coalfields
Comparative ranking of coalfields inside and outside South Africa on exploration level, resource size and infrastructure, for companies deciding where to explore next.
by Grant van Heerden | August 2004
A rating and ranking system was applied to South African coalfields and, separately, to the coal bearing countries elsewhere in the Southern African Development Community. The Waterberg ranked highest in South Africa and is the coalfield most worth detailed investigation as Witbank output declines. Botswana ranked highest among the other member states on contained resources and exploitation potential.

Monitoring and geochemical modelling at five pilot sites, on undisturbed soils and on opencast spoils, showed that most soils held a large share of the applied salt in the upper unsaturated zone and that salinity built up slowly. Leachate volumes, leachate quality and aquifer mixing ratios were quantified. Irrigation is recommended on alternating pivots and for no longer than ten years in one area.
