Description
The study assessed the feasibility of establishing a 500 kW thermal Circulating Fluidised Bed (CFB) combustion test facility to evaluate the technology under South African conditions. It found that the proposed facility is technically feasible, with Eskom Rosherville identified as the preferred site, and provides a foundation for progressing to the next phase of detailed engineering, procurement, construction and commissioning.

The Estimation of Greenhouse Gas Emissions from South African Surface and Abandoned Coal Mines

R1500,00
Gas sampling on coal mine dumps found rehabilitation very effective at cutting emissions. Even incomplete rehabilitation held carbon dioxide below about 1 kg per square metre a year, against over 100 on unrehabilitated ground and as much as 7 000 where combustion was active, though burning areas were small. Sulphur oxides, nitrogen oxides, ammonia and methane were low.

R1500,00
A framework for planning land use on rehabilitated coal mining land, built from a review of international and national regulatory and corporate guidance and from interviews with industry practitioners. The review found that existing guidance requires land to be returned as close as possible to its pre mining condition, while community needs are pushing rehabilitation towards alternative land uses that can sustain livelihoods.
Intra-seam Sedimentological Controls on Coal Quality: 2 Seam, Witbank Coalfield

R1500,00
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.
