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.

What this report found

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.

What this report found

Government and industry aeromagnetic data over the Witbank Coalfield were merged into one set of maps and GIS compatible files, and roughly 1200 dyke traces were interpreted from them. Purchase of a 200 m line spacing government survey removed the need for infill flying. One participating company valued advance knowledge of a single underground dyke at about R15 million.

Development of Junior Management and Supervisory Personnel for the Mining Section of the Future

2004

Interviews, questionnaires and on site observation at three South African collieries, with recommended training content and selection criteria for supervisors and junior managers in mining sections.

What this report foundMines already provide substantial training and their junior managers were found motivated and committed, yet development at this level remains problematic.

What this report found

Mines already provide substantial training and their junior managers were found motivated and committed, yet development at this level remains problematic. Gaps sat in commercial exposure, financial and accounting skills, industrial relations, quality standards, administration and project management. The report sets out the attributes to screen for at appointment and a framework that makes candidates responsible for their own development.
