Summary:
Bituminous coal is mined from the Permian Moranbah and Rangal Coal measures. Products range from premium quality, low volatile, high vitrinite, hard coking coal to medium volatile hard coking coal, to weak coking coal, some pulverised coal injection (PCI) coal and medium ash thermal coal as a secondary product.
Resources occur in the Rangal Coal Measures of Late Permian age, in a graben-like structurally deforme basin. Dips in the coal measures are variable and range from 5–30°. Two seams are present: Leichhardt — 5.1m average thickness; Vermont — 2.8m average thickness.
