Project 8.3.3 – Framework to Guide Mine-related Land Use Planning Towards Optimisation of the Coal Mining Rehabilitated Landscape
Masters research combining a review of rehabilitation guidance with South African industry interviews, for mine planners and regulators deciding what post mining land should become after closure.
A framework for planning land use on rehabilitated coal mining land, built from a review of international and national regulatory and corporate guidance and from interviews with industry practitioners. The review found that existing guidance requires land to be returned as close as possible to its pre mining condition, while community needs are pushing rehabilitation towards alternative land uses that can sustain livelihoods.

Compaction on rehabilitated opencast land restricts effective rooting depth so severely that only a small proportion of arable and grazing areas reach their stated capability. The review sets out the causes and symptoms, argues that symptoms are usually treated without addressing the cause, and recommends site specific, resource based management, mechanisation choices weighed against compaction, and land capability standards aligned with international codes.

Dense medium cyclones on the fine coal fraction lifted product yield well above the spiral circuit they were compared against and gave closer control of product quality. Cut point density control proved the hardest part of running the plant, medium properties being critical. Magnetic separator capacity had to match the duty, and a basement was needed to contain and recover medium spillage.
