Located around 160km west of Mackay in the Bowen Basin, Queensland is the Eaglefield mine which produces high-quality hard coking coal for export markets.
The open cut mine was acquired by Peabody in 2004 and is a shared site with North Goonvella (another Peabody operation).
Due to this arrangement, Eaglefield’s coal is supplied to the North Goonvella coal washery.
Eaglefield yields about 1.5 and 2.5 million tonnes per annum of coking and thermal coal, with associated waste material mined at a rate of between 15 and 25 million bank cubic metres per annum.
The mine has recently incorporated the cast blast and dozer push techniques in the mine. This technique involves increasing the amount of explosive in a blast and utilising the additional energy of a blast to throw material across the pit, avoiding the need for truck and shovel operations to move the material. Following the blast, carry dozers transport remaining material.
Macmahon currently operates the site, including the mining, overburden and interburden of coal, all drill blast operations and the run-of-mine (ROM) coal feed. It is also responsible for the complete pit design, waste dump design, drill and blast design and full scheduling.
Peabody is currently looking at expanding the Eaglefield mining operation within the existing mining lease.
