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.

Ion exchange treatment of acid mine drainage from a closed KwaZulu-Natal colliery was piloted and shown to give effluent free processing, converting the salts into saleable products rather than sludge and brine. Reverse osmosis had previously produced water of discharge standard but left both. Combined flow from the two mine compartments averaged 4.6 megalitres a day.
Recharge in Rehabilitated Opencast Collieries
2019
Groundwater levels and pumping records from five rehabilitated opencast pits at South African collieries, for hydrogeologists and closure planners estimating post-mining water balances.
What this report foundRecharge factors of 23.5 per cent and 12.9 per cent were calculated at the two rehabilitated pits with complete data.

Recharge factors of 23.5 per cent and 12.9 per cent were calculated at the two rehabilitated pits with complete data. The higher value reflected surface drainage towards the pit centre and eroded topsoil; the lower one, a deep pit floor with well compacted spoil and intact cover. The rates are site specific and no generic formula could be derived.

Ion exchange was assessed as a treatment route for brine arising from mine water cleaning, from a market rather than a plant performance standpoint. World demand for ion exchange resins was expected to pass 535 million dollars by 2015, driven by urbanisation, pollution and shortages of clean water in developing regions.
