Arnot mine is 43km east of Middelburg in Mpumalanga, South Africa, and was contracted to supply coal to the nearby Eskom Arnot power station until 31 December 2015. |
Summary:
The S1 and S2L are the only coal seams of economic interest in the Arnot mining right area, and these correlate with the typical Witbank coalfield seams. The pre-Karoo basement topography consists of both felsites and diabase intrusives associated with the Transvaal supergroup and Bushveld igneous complex respectively. The Vryheid formation is conformably deposited on top of the reworked glacio-fluvial tillite of the Dwyka group.
Mining Methods
- Truck & Shovel / Loader
- Bord-and-pillar
Summary:
The mine achieved by extracting no 2 seam lower (S2L) from two underground shafts, namely no 8 and no 10 shafts, using mechanised mining equipment (bord-and-pillar extraction) while Mooifontein open-cast used conventional truck-and-shovel, roll-over mining method to extract S2L and no 1 seam (S1).
