SnapshotAnglo American’s steelmaking coal assets in Queensland include the Moranbah and Grosvenor mines. Grosvenor is an underground longwall operation producing premium low-volatile hard coking coal.

The mine has been inactive since June 30, 2024, when Anglo American suspended production following an underground coal gas ignition incident on June 29, 2024. The steps toward a safe re-entry into the mine are expected to take several months due to likely underground damage.

Before the suspension, Grosvenor’s coal products were transported via an on-site rail loading facility shared with Moranbah North and exported to steelmaking customers via the Dalrymple Bay Coal Terminal.

Grosvenor is a joint operation between Anglo American, represented by Anglo Coal (Grosvenor Management) Pty Ltd and a consortium of Japanese Steel Companies.

On November 25, 2024, Peabody Energy, Inc. announced its agreement to acquire Tier 1 Australian metallurgical coal assets from Anglo American, including the Grosvenor mine. The transaction is expected to close in mid-2025.

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. The Moranbah Coal Measures range in thickness from 250–300 m and contain splits from nine coal seam groups. The target seam is the Goonyella Middle (GM) Seam.

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. 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.
