What this report found

A regional scheme to collect, treat and re-use mine water in the Upper Olifants River Catchment has merit, with the mines best placed to start it through a dedicated mine water company that brings in the water services authorities. Water legislation supports the scheme provided the regulator allocates mine water as a resource. Viability rests on the tariffs mines and water users pay.

What this report found

Sets out good practice for planning, implementing, monitoring and adaptively managing land rehabilitation at surface coal mines, with generic rehabilitation objectives, implementation actions and suggested relinquishment criteria for each component. It updates guidance first issued in 1981 and revised in 2007, reflecting later changes to South African rehabilitation legislation.

What this report found

Conventional rehabilitation relies on lime, fertiliser and compost to build fertility and select adaptive species, which produces short term cover but rarely a self sustaining ecosystem. The work argues for treating soil microbes as part of the system, since bacteria drive nutrient cycling, organic matter breakdown and soil aggregation, and proposes conditioning plants with adapted rhizosphere bacteria on coal waste substrates.
