The Estimation of Greenhouse Gas Emissions from South African Surface and Abandoned Coal Mines
2012
Direct sampling across burning, burnt out and rehabilitated dumps at surface mines covering just over half of national surface production, scaled to a national emissions estimate.
What this report foundGas sampling on coal mine dumps found rehabilitation very effective at cutting emissions.
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.
Application of Earth ion Exchange Technology to Convert Acid Mine Drainage from Kilbarchan Colliery into Saleable Products
2010
Pilot scale ion exchange trial on acid drainage pumped from a closed colliery in KwaZulu-Natal, for mine water managers weighing alternatives to reverse osmosis.

Ion exchange treatment of acid mine drainage from a closed KwaZulu-Natal colliery was piloted and shown to give effluent free processing, converting the salts into saleable products rather than sludge and brine. Reverse osmosis had previously produced water of discharge standard but left both. Combined flow from the two mine compartments averaged 4.6 megalitres a day.
A diatom based index for pans impacted by acid mine drainage
2021
Wet and dry season sampling of epiphytic diatoms from reed, salt and grass pans on the Mpumalanga Highveld, validating a biomonitoring index for mine affected depressional wetlands.

Level of acid mine drainage disturbance explained more of the variation in diatom communities than any other factor, with pan type second and season not significant. Sulphate and calcium concentrations and sulphate to chloride ratios were higher in disturbed pans of every type. Pan type specific indices were tested against established riverine indices.
