Collinsville was recognised as a potential coalfield as early as 1866. The mine moved from underground to open cut operations progressively from the 1950s with large-scale open cut operations occurring in 1983 and the last underground mine completing operations in 1997. |

Summary:
Along the structurally disturbed north-eastern edge of the Bowen Basin, the coals range in rank from anthracite to low volatile bituminous, and deposits tend to exhibit a complex structure. Coals in the central part of the basin are medium to high volatile bituminous and include the best coking coals. Structural deformation in these deposits is generally relatively mild.
Coal-bearing horizons have been preserved at many stratigraphic levels throughout the Bowen Basin, but deposits of economic importance are restricted to four groups.
Group II coal measures, also of Early Permian age, occur as several unconnected deposits located around the northern and western margins of the basin. These include the Collinsville Coal Measures in the north.
Group III coals of Late Permian age were deposited on the Collinsville Shelf, under conditions which varied from a marine- influenced deltaic environment in the German Creek Formation, to dominantly fluvial flood plain environments in the Moranbah Coal Measures. These formations contain most of the high-grade coking coal deposits mined in Queensland.
Collinsville Coal Measures of Early Permian age, containing up to nine coal seams; extensive faulting and igneous intrusions have affected all seams to varying extents, with five seams currently worked; average thicknesses of these are: Garrick — 2.6m; Scott — 1.8m; Denison — 2.8m; Bowen — 6.5m; and Blake — 10m.
Mining Methods
- Truck & Shovel / Loader
- Dragline
Summary:
The Collinsville operations comprise the Collinsville open-cut mine, and the small Pipeline mine about 15km to the south-east. The mining method for both mines is truck and shovel for overburden removal, as well as a dragline at Collinsville open-cut. A contractor operates the mining, coal handling, and preparation plant operations.
An additional dragline (BE 1370) was relocated from Newlands Mine in 2004.
Current fleet / Equipment:
- 2 Draglines
- 3 Excavators
- Fleet of 777 and 793 trucks
- Ancillary equipment to support plant (eg. 2 water trucks, graders, dozers).
Processing Technologies
- Wash plant
- Dense media separation
Summary:
Preparation plant - Dense medium and classifying cyclones (capacity 400tph).
