Best Practice Guidelines for the Management of Spontaneous Combustion in Opencast Coal

G Stenzel

Guidelines drawn from site testing at opencast coal operations, including trials of gypsum and fly ash sprays applied with a hydro seeder. For pit supervisors and mine safety staff.


By Gerhard Johann Stenzel | 2024

What this report found

Practical guidance for opencast operations covers early detection with low cost thermal cameras, prevention, and the treatment methods in current use: water sprays and cannons, sand cladding of highwalls and stockpiles, removal of burning coal by dragline, tipping into water ponds and the treatment of sinkhole areas. A three month full scale trial of sprayed fly ash as an antioxidant is reported.

M van Schoor

What this report found

No surface geophysical method can map individual bords and pillars at the depths typical of the Witbank coalfield, a limit the review attributed to physics rather than to technology, since the targets are small relative to their depth and conductive layers often lie above the seam. Borehole laser scanning remains the workable option, with sonar suited to flooded workings.

What this report found

A framework for planning land use on rehabilitated coal mining land, built from a review of international and national regulatory and corporate guidance and from interviews with industry practitioners. The review found that existing guidance requires land to be returned as close as possible to its pre mining condition, while community needs are pushing rehabilitation towards alternative land uses that can sustain livelihoods.

What this report found

Ion exchange converted reverse osmosis brine from a power station treating colliery water and cooling tower blowdown into fertiliser and explosives salts, with no liquid effluent left to dispose of. Part of the water rejected by the reverse osmosis stage was also recovered as potable water. Brine is currently used for dust suppression and stored underground.
