Summary:

Bituminous coal is mined from the Permian Rangal Coal measures. Produces a range of coking coal and pulverised coal injection (PCI) coal.

Rangal Coal Measures of Late Permian age dipping west at 5–10°; the coal is a high-energy semi- anthracite which occurs in a 9–14m thick seam locally referred to as the Main seam.


Mining Methods

  • Truck & Shovel / Loader
  • Dragline
