Agricultural Research on Rehabilitated Coal Mined Land (1994-2001) Conducted in Terms of the Kraai Van Niekerk Report
2001
Consolidated review of six field studies on highveld opencast rehabilitation, covering soil profiles, pasture performance, crop potential and soil water, for mine environmental staff and regulators.
What this report foundRehabilitated opencast soils carried pastures and cash crops, but compaction and cover soil depth set the ceiling on what they could produce.

Rehabilitated opencast soils carried pastures and cash crops, but compaction and cover soil depth set the ceiling on what they could produce. Only land with deep cover soils suited maize and sunflower, and deep ripping with regular tillage was needed. Bulk density standards were not met at the trial sites, which the review judged enough to have changed the results.
Characterization of Spontaneous Combustion Emissions
2005
Aircraft and ground monitoring at a working colliery in summer and winter, measuring trace gases and particulates from spontaneous combustion, for air quality management and mine planning.

Aircraft and ground based measurements at Kleinkopje Colliery showed spontaneous combustion to be a significant source of fine particles, with PM2.5 concentrations 91 per cent higher inside a combustion plume than outside it. Sulphur dioxide, nitrogen dioxide and carbon dioxide were also raised in plume, and benzene and toluene were detected. Average particle size was below one micron.
