Paper Abstract

Open-cast mining, involving severe disturbance, of shallow coal deposits has taken place in Mpumalanga, South Africa for some time with little control until recently. Current legislation requires soil investigations. The soils are agriculturally productive and merit effective rehabilitation, but several problems in this process can occur, leading to drastically reduced agricultural productivity. GPR investigation of these mine soils can help with the mapping of the depth to spoil after rehabilitation, on a significantly more cost-effective basis than traditional point observations. A field trial was carried out as part of a research project at Kleinkopje Colliery where it was shown that, despite wet conditions due to irrigation, GPR was able to map spoil depth around six times faster than augering. There is substantial scope in South Africa for GPR to make a significant contribution in this field.
