APPENDIX I
The underground haulage system described on page 324, Vol. I, is be­ing superseded by two other systems. In De Beers and Kimberley Mines, where the blue ground has not to be trammed very far before it is dumped into the passes, side tipping trucks, holding 20 cubic feet of ground and drawn by an endless wire rope, are used. The trucks are drawn up an incline as they get near to the shaft and are then detached from the rope and run by gravitation to the shaft, where they are both tipped and righted again automatically.
In Dutoitspan, Bultfontein, and Premier Mines, where the distances to tram in the mines themselves are much greater, the 20-cubic-feet trucks will be drawn by electric locomotives, which will be installed under the trolley system. The tipping into the chutes at the shafts will be done automatically, as described above.
