Description
Soil Covers for Backfilled Surface Coal Mine Pits and Coal Discard Facilities to Mitigate Acid Rock Drainage and Seepage Impacts Technical guideline The study focussed on soil covers that can provide a simple, cost-effective and passive source-directed measure to reduce high volumes of excess pit water and to mitigate acid generation and related seepage impacts from backfilled surface coal mine pits through land rehabilitation. This can result in cost savings to the mine on water treatment for a rehabilitated pit and during concurrent rehabilitation, while reducing the mine’s residual risk on seepage impacts and potential decanting of excess pit water.

The financial benefit of bees to a rehabilitating site could not be modelled with confidence, and a field trial to show direct benefit is hard to configure because so many variables affect rehabilitation. Apiaries suit sites where bee friendly plants are established, the return coming through honey yield rather than measured gains in biodiversity or ground cover, at low establishment cost.

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.
