R1500,00
Shallow coal suitable for small scale opencast working was mapped in the northern Witbank and Highveld coalfields, using a limit of 30 m from surface to the top of the first seam. Most outcrop areas examined proved already mined out, and depth to the top seam increases southwards, though some ground remains available. Obtaining resource data was the main obstacle.
Rehabilitation of Mined Land – Soil Compaction Alleviation
2011
Final report on mined land rehabilitation trials comparing pasture species and organic amendments on compacted mine soil against normal agricultural soil, for rehabilitation and pasture planning.
What this report foundExperimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material.
R1500,00
Experimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material. Survival of 16 pasture species was recorded on mechanically ameliorated compacted soil, dry matter and leaf area were measured for tall fescue and cocksfoot at different levels of organic material, and soil fertility, bulk density and root biomass were tracked under irrigated and dryland grass.
Detection of Old Workings, Sinkholes, Underground Fires and Acid Mine Pollution Using Geophysics and Airborne Thermal Infrared Imagery
2002
Field trials at four collieries comparing ground and airborne geophysical methods, with case studies and an applications guideline for the Witbank and Highveld collieries.

R1500,00
Micro-gravity, electrical resistivity and time domain electromagnetics located the boundary between old workings and virgin ground, but no ground technique tested could resolve individual bords and pillars at the depths typical of the Witbank and Highveld coalfields. Airborne thermal infrared surveys worked well as a low cost regional reconnaissance tool for shallow sinkholes, fires and possible pollution plumes.
