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.
Rangal Coal Measures of Late Permian age, dipping 3-5° to the east. Three major coal seams are present: Top (Aries) - 0.8-1.5m; Middle (Castor) - 2-3.5m; Main Lower (Taurus/Argo) - 5-7m. Complex seam splitting occurs along the 35km strike length of the mine.
