Rooiberg D Mine
Vellefontein 517 KQ farm.
Vellefontein Mine also known as 'D' mine in the Rooiberg group.
At Vellefontein (D Mine), the mineralization is in the form of flatly dipping bedded lodes. These lodes dip at approximately 10 degrees and are mined by updip scraper cleaning methods at stope widths of around 1,0 m.
Values on the lodes are limited by payshoots and faulting. Individual stope panels are served by dip gulleys at 18 m centres. A line of 3,0 by 3,0 m pillars at 6,0 m centres is left on one side of the gulley, giving a face width of approximately 13,5 m.
Support on the face is confined to minepoles at 1,8 m centres on dip and strike. Cleaning is done by scraper winches down the dip gulley, either into Cousin Jack boxes or via Chinaman chutes into cars in the lode drive.
The in situ pillars are a very successful form of support, and no problems are encountered with hanging wall control either at Vellefontein or at C Mine. Main levels are situated 25 m apart and at Vellefontein are equipped with 600 mm gauge tracks. The lowest level at Vellefontein is at 203 m below surface.
The mine is served with a surface incline and a subincline for rock hoisting and a chairlift. Ore is transported approximately 10 km by road to the concentrator at A Mine.
Cassiterite can be found on the dumps predominantly as crusts of small lustrous crystals from 0.5mm to 3mm covering joint surfaces in a red arkosite rock matrix.
