Description
The study assessed the feasibility of establishing a 500 kW thermal Circulating Fluidised Bed (CFB) combustion test facility to evaluate the technology under South African conditions. It found that the proposed facility is technically feasible, with Eskom Rosherville identified as the preferred site, and provides a foundation for progressing to the next phase of detailed engineering, procurement, construction and commissioning.

Mapping abandoned, inaccessible bord and pillar workings comes down to two options: borehole deployed laser or sonar scanning, or sensors carried in by unmanned vehicles. Drone mounted laser scanning for air filled voids and sonar carried by small submersibles for flooded workings were judged the most promising, but intrinsic safety, deployment and the risk of losing equipment still favour borehole methods for occasional use.

R1500,00
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.
