Characterization of Spontaneous Combustion Emissions
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.
by Dr Luanne Otter, Dr Stuart Piketh, Ms Thabile Dlamini and Mr Roelof Burger | February 2005
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.

No operating full scale frictional ignition test facility was found anywhere in the world, and building one was judged expensive, impractical and unlikely to justify its cost against laboratory scale testing. Effort should instead go to small scale laboratory equipment using South African rocks, and to expanding geological data such as silica distribution and petrographic analysis.
