A regional monitoring programme was found to be viable and is proposed as a public private partnership covering air emissions, air quality and energy efficiency on the Mpumalanga Highveld. The assessment concluded that the worst health impacts fall on residential areas, driven by inefficient coal burning for heating and by housing sited close to large industry.
Guideline for Mine Closure Relinquishment Criteria
2023
Review of closure and relinquishment law in Australia, Canada and South Africa, with four mechanisms for reaching agreement compared. For closure planners and regulators.
What this report foundRelinquishment criteria follow from the agreed post-mining land use. The land use is the goal and the criteria measure whether it has been reached.

Relinquishment criteria follow from the agreed post-mining land use. The land use is the goal and the criteria measure whether it has been reached. The guideline sets out a framework for approving those criteria at each mining phase, from the initial environmental management plan through to decommissioning, and compares South African practice with Australian, Canadian and international guidance.
Flammability, corrosion resistance and environment by V Mhlawakhe.pdf
Laboratory work turning high ash coal fines into moulded building composites, comparing coal tar pitch against a silicone binder, with strength, burning, corrosion and leaching tests. For product developers.
What this report foundAir blowing converted coal tar into a pitch with 11.27% volatile matter and 87.68% fixed carbon, which bound high ash coal fines into structural composites.

Air blowing converted coal tar into a pitch with 11.27% volatile matter and 87.68% fixed carbon, which bound high ash coal fines into structural composites. Compressive strengths ran from 106.58 to 344.71 MPa and flexural strengths from 48.75 to 159.30 MPa. Flammability was low across all composites and corrosion rates stayed below those of some commercial ceramic tiles.
