Description
The Carbon Farming Model for Rehabilitated Coal Mine Land assessed the potential to transform rehabilitated coal mine land into productive landscapes that support biomass production, renewable energy generation, soil regeneration, carbon sequestration and community enterprise development. The project demonstrated that rehabilitated mine land can successfully support high-biomass species, particularly when supported by organic amendments such as biochar and digestate. It provides a practical and scalable approach for turning post-mining land from a rehabilitation liability into an environmental, economic and social asset.

Audit and Diagnostic Assessment of Productivity in Continuous Miner Sections
2003
Mine level study of the human and social influences on continuous miner section output, using interviews, focus groups, observation and work study at participating collieries, for mine managers.
What this report foundSection performance was limited by the will and motivation of the workforce, not by equipment, layout or technical competence, all of which were found sound.

Section performance was limited by the will and motivation of the workforce, not by equipment, layout or technical competence, all of which were found sound. Team based bonus payments were the strongest motivator and reinforced cooperation across shifts and functions, but dependence on bonus income to meet monthly expenses turned it into a source of stress. Recognition in front of colleagues and family motivated strongly.
Treatment of Sulphate Rich Effluents with the Combined Electrolytic/Biological Process
2003
Laboratory work on producing hydrogen by electrolysis as the energy source for sulphate reducing bacteria, aimed at cutting the running cost of treating sulphate rich mine water.
What this report foundHydrogen for biological sulphate removal can be generated on site by electrolysis more cheaply than it can be bought.
R1500,00
Hydrogen for biological sulphate removal can be generated on site by electrolysis more cheaply than it can be bought. Stainless steel electrodes in acid mine drainage gave hydrogen at about a third of the bought in price while oxidising ferrous iron to ferric, which helps downstream treatment. Iron and zinc electrodes dissolved too quickly to be viable.
