Project Profile: Wilpinjong Mine

Project Start Date: 2nd Quarter 2005 (Q4 FY 2005)

Project Finish Date: 4th Quarter 2007 (Q2 FY 2008)

Sedgman initially undertook resource evaluation, definitive feasibility study and cost estimation of a 1,600 t/h coal handling and preparation plant (CHPP). Sedgman was subsequently engaged to undertake the detailed engineering design, procurement and commissioning. The combination of a modular bay plant design and ‘pancake’ construction method minimised working from heights and resulted in a much safer workplace. Construction costs were reduced by 10% with the plant was erected two weeks faster than could have been achieved through conventional methods.

Plant features include:

  • ROM coal receival and sizing system with 350 t ROM dump hopper, feeder breaker, sizers and a roller screen to a raw coal radial stacker discharging on to a 2,000 t raw coal stockpile
  • 800 t/h single-stage 1,300 mm DMC, spirals CPP with conventional coarse coal/fine coal centrifuge dewatering
  • Rejects disposal via conventional coarse reject conveyor and thickener tailings pumping
