New Sasol Mines:
THE NEW MINES
The proposed Thubelisha replace- ment mine will have a capacity to produce between 9,5-million tons and 10,5-million tons a year. In the north-east of the Secunda complex, Thubelisha will supply both the export market and to Sasol Synfuels. The first portion of the mine is due to come on stream in 2012 and will ramp up to full production over a three-year period. A 17-km-long overland conveyor will transport coal to the beneficiation plant. It is a project with a value of some R3,3-billion and the main components are three shafts that are in the process of being sunk, at a capital investment of some R500-millon. The materials handling component of the mine – the overland conveyor, the bunkers and asso- ciated infrastructure – will require an investment of R850-million and the remaining investment will be on surface infrastructure, including power provision and roadworks. Construction on Thubelisha, which is being built on a greenfield farm site, began in June. The proposed Impumulelo replacement mine will be situated at the south-western portion of the Secunda complex and have a 28-km overland conveyor. Impumulelo, at a depth of about 190 m, will have a capacity to produce 10-million tons a year of coal. The first production from the mine will be needed in 2014 and the entire mine will come into full operation over a four-year period. The interesting aspect at Impumulelo is that two coal seams may be mined simultaneously, which lifts the capital investment to R5-billion. The first coal seam of about 3 m is roughly 190 m below the surface and 30 m below the first seam is the
second seam. Should the twin-seam option be taken, a vertical shaft would be sunk to the deepest seam and an incline shaft built under-ground to the lower seam. Coal will be transported through bunkers to the lower seam from where it will be conveyed through an incline to a surface bunker. The two-seam mine, if approved, would present water- management challenges, for which a sound watermanagement strategy is being put in place.
