Deposit Type

  • Sedimentary

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

Summary:

Mining conditions over the area are favourable for open-pit extraction with soft overburden and relatively low stripping ratios. Overburden is removed using a dragline, hydraulic backhoes and rear dump trucks.
