Evaluation of Three Native Grass Species and a Tree Species for Coal Mine Rehabilitation
Field trials established on prepared topsoil at three Mpumalanga Highveld collieries and measured to 2007, covering survival, cover, biomass and tree growth, for rehabilitation planners.
Cynodon dactylon outperformed Themeda triandra and Hyparrhenia hirta, reaching 100 per cent survival and cover at all three trial sites by 2007 with or without fertiliser. Acacia sieberana reached 97 per cent survival at Kleinkopje Colliery but grew poorly at Optimum and Syferfontein. Planting plugs suits slopes too steep for a planter machine and buffers against pasture grass intrusion.

Electrical and electromagnetic ground surveys were run over a Waterberg profile with borehole logs and three dimensional seismic data as control, to test whether cheaper methods can match seismic reflection for locating coal and faults. Resistivity tomography at two electrode spacings, frequency and time domain electromagnetics, controlled source audio magnetotellurics and magnetics were all acquired. Results are preliminary.

Geophysical logging of boreholes above three Witbank seams identified clay rich matrices, stiffness changes, bedding planes and the principal stress direction, and picked up fractures in 30 to 75 per cent of cases. Core logging found most of the same features faster, so routine use was not recommended unless stiffness and stress direction matter.
