Mining Methods
- Truck & Shovel / Loader
- Dragline
- Bord-and-pillar
Summary:
The Coal Resources have the potential to be extracted via both opencast truck and shovel or dragline, and underground bord and pillar mining methods.
The Tweefontein Opencast Operation had a slight decrease in the Coal Reserve footprint of the Klipplaat and Makoupan pits (-0.4Mt). Mining rights for Tweefontein North expired on 27 March 2020, and an application for a renewal was lodged in March 2020.
Tweefontein South: Tweefontein South Complex is contained in the iMpunzi new order mining right and in the Klippoortjie old order mining authorisation.
No mining was conducted in 2020 and the No. 5 Seam Addcar Coal Reserves remain available for future extraction. Mining rights for Tweefontein South expire on 28 March 2029.
