Kestrel Prefeasibility Study

Back to case studies

The existing Kestrel coal handling and preparation plant (CHPP), located 50 km north east of Emerald in central Queensland, is expanding its underground mining and intending to process additional capacity through its existing facilities.

The project required assessment and definition of the necessary changes covering longwall, overland conveyors, materials handling, processing, rail loading and infrastructure to increase capacity from existing 1 000 t/h to 1 600 t/h.

Ausenco’s assessments encompassed the area of raw coal receival from the overland conveyor through to product stockpiling.

The investigation identified the scope of the various coal handling and preparation plant modifications, required over a number of different operating scenarios. Step changes in both capital and operating costs were determined.

Major consideration was given to the surge/stockpiling requirements given the operating logistics of the longwall and processing interface.

Final recommendations were to reduce the total increase of capacity from 1 600 t/h to 1 400 t/h and associated CHPP modifications.
