Anglo American’s Capcoal complex comprises Capcoal Open Cut Mine (Lake Lindsay and Oak Park), Grasstree Mine, Aquila Mine, the Coal Handling and Preparation Plant and associated infrastructure.

An underground longwall operation at Grasstree is replaced by Aquila.

Lake Lindsay, Grasstree and the Aquila Project are owned by the Capcoal Joint Venture and Oak Park is owned by the Roper Creek Joint Venture. Due to the differing ownership structure, the attributable shareholding of Capcoal OC (Lake Lindsay and Oak Park) is determined annually using the proportion of the Saleable tonnes in the individual pits. The calculated ownership percentage therefore varies each year due to differing production schedules.

Deposit Type

  • Sedimentary


Summary:

The Capcoal complex consists of the Capcoal Open Cut and Grasstree, Aquila underground mines, near Middlemount, in Bowen Basin. The majority of coal of Capcoal (OC) is mined from the German Creek Formation, which contains five coal seam intervals known as the German Creek, Corvus, Tieri, Aquila and Pleiades seams. The Aquila is planning to extract reserves from the Aquila and Aquila Lower seams, which occur in the upper part of the German Creek formation. The project is located on the north-western flank of the Bowen Basin, a sedimentary basin comprising Permian to Triassic age geology. The Triassic strata sub-crop at least 5 km east of the project longwall mining area and are not present within the project longwall mining area or its surrounds. A veneer of more recent Tertiary and Quaternary age sediments typically overlie the Bowen Basin strata. The relevant geology in the vicinity of the project longwall mining area includes: -Quaternary alluvium associated with German Creek and Little Parrot Creek; -A veneer of Tertiary sediments of the Duaringa Formation; -Permian coal measures including the target German Creek Seam (GC seam). Alluvium is absent from the project longwall mining area. Regionally, the distribution of alluvium is limited to localised deposits associated with ephemeral creeks. The German Creek alluvium is located to the south of the project longwall mining area and the Little Parrot Creek alluvium is located approximately 1.6 km north-east of the proje ........

Summary:

Capcoal comprises opencast operations at Lake Lindsay and Oak Park, with an underground longwall operation at Grasstree and Aquila. Aquila The Aquila comprises a single longwall underground mine and supporting infrastructure. The operation will target two seams, the Aquila and Aquila Lower coal seams. The depth of the Aquila seams from the surface varies from approximately 70 metres up to 280 metres with a nominal seam height ranging from 1.8 metres to 2.2 metres. The longwall will be supported by two continuous miner development units with ROM coal transferred from the underground development and longwall mining units via a new underground conveyor belt system to a new surface conveyor and onto an expanded ROM stockpile. Grasstree A longwall is a complex system of mining equipment that incorporates hydraulic roof supports (called ‘chocks’ or ‘shields’), coal cutting and coal transport equipment. Longwall mining involves extracting rectangular panels of coal, typically around 150 m to 400 m wide, up to 7 km long and 2 m to 5 m thick. Longwall panels are defined by access roadways that are constructed around the perimeter of each longwall panel. These roadways provide access for the installation of the longwall mining equipment, mine workers, and equipment and services. Longwall mining involves a coal shearer travelling back and forth across the width of the longwall panel, starting from the furthest point progressively removing the coal from the panel back to the main ........
