The Optimum Methodology for Conducting High Resolution, Shallow Reflection Seismic Surveys on South African Collieries
Field procedure standards for high resolution seismic work over seams 30 to 100 m deep, trialled at two Mpumalanga collieries, with a cost comparison against exploration drilling.
by Marianne J. Maccelari | December 2001
Shallow reflection seismic surveys failed on South African collieries mainly because too little preliminary data, from vertical seismic profiles and noise spreads, was gathered before the surveys were designed. Following the field procedures set out here produces usable data for mine planning. For target depths under about 150 m, exploration drilling stays cheaper, because shot holes must be drilled below the weathered layer.

The separator handled fine coal and produced a 28 MJ/kg product, but its measured separation efficiency was lower than that of conventional dense medium cyclones and it was harder to operate. Two efficiency tests produced no evidence that the unit outperforms cyclones on fine coal, so cyclones were recommended when the plant was rebuilt at its next site.

Conventional rehabilitation relies on lime, fertiliser and compost to build fertility and select adaptive species, which produces short term cover but rarely a self sustaining ecosystem. The work argues for treating soil microbes as part of the system, since bacteria drive nutrient cycling, organic matter breakdown and soil aggregation, and proposes conditioning plants with adapted rhizosphere bacteria on coal waste substrates.
