The Estimation of Greenhouse Gas Emissions from South African Surface and Abandoned Coal Mines
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.
by A.P. Cook and P.J.D. Lloyd | December 2012
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.

Nine bituminous coals from the Witbank, Waterberg and Soutpansberg coalfields all formed compacts without a binder, and the process worked better with coking coals. Reactive maceral content, free swelling index and Hardgrove grindability index governed briquette strength, with ash and kaolinite contents also contributing to bonding. Briquetting pressure, feed moisture and particle size distribution controlled the outcome.
