SnapshotAnglo American’s steelmaking coal assets, located in Queensland, include the Moranbah and Grosvenor mines. The mines are underground longwall operations and produce premium quality hard coking coal.

The next longwall moves scheduled at Moranbah and Grosvenor are both in the third quarter of 2024.

On June 30, 2024, Anglo American suspended production at its Grosvenor steelmaking coal mine in Queensland, Australia, following an underground coal gas ignition incident on 29 June 2024.

The mine team is working with specialist teams from the Queensland Mines Rescue Service and the regulatory authorities to extinguish the underground fire, prior to being able to assess the steps towards a safe re-entry into the mine. These procedures are expected to take several months as a result of the likely damage underground.

Deposit type

  • Sedimentary

Summary:

The sedimentary strata of Grosvenor, Moranbah North and Moranbah South were deposited on the tectonically stable Collinsville Shelf on the north western flank of the basin. Basalt flows that follow structures associated with the Permo-Carboniferous strike slip system partially overlie Grosvenor, Moranbah North and Moranbah South.

Underground coal mining targets coal seams at various depths. Grosvenor’s target seam is the Goonyella Middle (GM) seam. The depth of cover of the GM seam across the Grosvenor site varies from 100 to 500 metres, with depth increasing toward the north-north-east of the mine plan. The thickness of the GM seam varies from four to six metres. 21 The seam gas composition is predominantly methane (more than 95%).

The GM seam is located within the Moranbah Coal Measures, the thickness of which ranges from 250 to 300 metres in the Grosvenor area.The Moranbah Coal Measures comprise nine coal seams and their associated splits. They are, in ascending order, the Goonyella Lower, Dysart Rider, Harrow Creek Lower, GM, P, Goonyella Rider, Goonyella Upper, QB and QA seams. The Moranbah Coal Measures also contain a tuffaceous marker bed known as the P-Tuff between the GM and P seams.

Above the Moranbah Coal Measures lies the Fort Cooper Coal Measures, the base of which is the Fairhill seam. Sediments overlying the Fort Cooper Coal Measures are predominantly comprised of sandstone, claystone, basalt, gravel and clays.
