BMA is owned 50:50 by BHP and Mitsubishi Development. BMA operates coal mine Peak Downs.
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.
Moranbah Coal Measures of Late Permian age dipping at 2–12° to the east; up to eleven coal seams/major seam splits are present. They are the S, R, Q, P1, P2, Harrow Creek Upper and Lower, DysartK, Dysart Upper 1 and 2, and the Dysart Lower 2 seams. Mining is mainly confined to the Harrow Creek and Dysart seam sequences, which average 4–5m each in thickness.
