Description

Conducted under the Coaltech Research Organisation (2022–2025), the research evaluated differently aged, rehabilitated coal-mined lands (4–30 years post-rehabilitation) across threeMpumalanga mines, focusing on soil recovery, pasture performance, forage quality, and theeconomic feasibility of integrating livestock within rehabilitated systems. Complementaryfield trials tested integrated cropping, zero grazing and grazing pressure effects on soil,vegetation, and forage dynamics under controlled conditions.

What this report found

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.

What this report found

Recharge factors of 23.5 per cent and 12.9 per cent were calculated at the two rehabilitated pits with complete data. The higher value reflected surface drainage towards the pit centre and eroded topsoil; the lower one, a deep pit floor with well compacted spoil and intact cover. The rates are site specific and no generic formula could be derived.
