Intra-seam Sedimentological Controls on Coal Quality: 2 Seam, Witbank Coalfield
2003
Sub-seam mapping at an opencast colliery in the Witbank area, setting out a method geologists and resource estimators can apply to other seams.
What this report foundSub-seams within the No 2 Seam were characterised at a single test site using lithology, seam thickness, proximate analysis, petrography and geophysical logs...

Sub-seams within the No 2 Seam were characterised at a single test site using lithology, seam thickness, proximate analysis, petrography and geophysical logs, and a paleoenvironmental model was built from them. Wireline logs separated coal from interburden but could not resolve the individual zones, because the physical differences are too subtle. Better sedimentological models gave better reserve and resource estimates.

A technology to condition plants with adapted Rhizospheric soil/substrate bacterial species to improve vegetation resilience and growth on rehabilitated land
2024
Review and proposed method for using soil microbial communities to establish lasting vegetation on coal waste substrates where topsoil is scarce. For rehabilitation and closure practitioners.

Conventional rehabilitation relies on lime, fertiliser and compost to build fertility and select adaptive species, which produces short term cover but rarely a self sustaining ecosystem. The work argues for treating soil microbes as part of the system, since bacteria drive nutrient cycling, organic matter breakdown and soil aggregation, and proposes conditioning plants with adapted rhizosphere bacteria on coal waste substrates.
Multi-client Aeromagnetic Data Merge & Interpretation – Witbank Coalfield
2005
Merged magnetic coverage and dyke interpretation across most Witbank mining and exploration ground, delivered as maps and GIS files for geologists planning around intrusions.
What this report foundGovernment and industry aeromagnetic data over the Witbank Coalfield were merged into one set of maps and GIS compatible files, and roughly 1200 dyke traces...

Government and industry aeromagnetic data over the Witbank Coalfield were merged into one set of maps and GIS compatible files, and roughly 1200 dyke traces were interpreted from them. Purchase of a 200 m line spacing government survey removed the need for infill flying. One participating company valued advance knowledge of a single underground dyke at about R15 million.
