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.

R1500,00
Shallow coal suitable for small scale opencast working was mapped in the northern Witbank and Highveld coalfields, using a limit of 30 m from surface to the top of the first seam. Most outcrop areas examined proved already mined out, and depth to the top seam increases southwards, though some ground remains available. Obtaining resource data was the main obstacle.
