Developing a Mechanised Cleaning System – for Cleaning Under and Around Moving Conveyors
2013
Follow on review of mechanised conveyor cleaning equipment close to being usable underground, flameproof and not, written to help the coal industry agree which options to develop.
What this report foundNo flameproof mechanised system for cleaning under and around moving conveyors was found to exist anywhere.

No flameproof mechanised system for cleaning under and around moving conveyors was found to exist anywhere. Of more than 200 mini machinery manufacturers identified worldwide, few build for mining, and only one or two products were near ready for surface use. Manufacturer interest in mining applications has since risen, but the industry has not settled on which technology to back.
Coal Mine Acid Mine Drainage Treatment and Sludge Processing

R1500,00
A modified alkaline barium calcium process was tested on coal mine acid drainage, using calcium hydroxide neutralisation, hydrogen sulphide metal removal and barium carbonate sulphate removal. Gypsum formation during water treatment fell by 80 per cent, cutting the sludge sent to costly downstream processing to a fifth. Temperature, reaction time, reagent ratios and feed particle size affected thermal treatment of the sludge.
