Ok Tedi Pit Dewatering Study
Feasibility study, costing and risk analysis for pumped dewatering of the Ok Tedi mine to a depth of 200 metres below the free draining level.
Design was based on up to 1600 litres per second in 8.8 metre rainfall area

Moranbah North Coal Mine
Dewatering system for longwall coal mine.
For operational reasons, dewatering bores were selected
Duty was 200 litres per second against 400 metre head.
|
Kestrel Coal Mine
Design and construction of 300 metre deep mine dewatering system including underground silt and waste trap and rising pipe.
The rising pipe was fitted with specially designed high pressure flanges which protected the MV power cable and control cable whilst maximising the size of the rising pipe which could be installed in the bore hole
The rising pipe design minimised maintenance costs by enabling a conventional crane (rather than drill rigs) to be used for installation and removal of the pump and pipeline
