Identify Remnant Coal Deposits for Potential Exploitation by Small Business Developments
Screening of near surface remnant coal for small scale miners in Mpumalanga, with a map of candidate areas and of ground already worked out.
by Deborah S Xaba & Lesley S Jeffrey | March 2002
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.

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.
