Description of Operations
From mine to millThe Ok Tedi mine is an open-cut operation in which about 78,000 tonnes of ore and 80,000 tonnes of overburden (waste rock) are mined each day from a pit covering about 2.6 square kilometres. The mine and mill operate 24 hours per day, 365 days per year. The mine's equipment fleet includes:
- 23 Caterpillar 789 haul trucks (170 tonne capacity)
- 3 Caterpillar 777D haul trucks (100 tonne capacity)
- 3 RH 200 O&K hydraulic shovels
- 3 Hitachi hydraulic excavators
- 3 Atlas Copco Pit Viper drill rigs and 1 Tamrock drill rig
- 10 Caterpillar D11 dozers
- 2 Caterpillar 992 loaders
- 3 Caterpillar 16H graders
- 2 Caterpillar 834B rubber-tyred dozers.
The Mine Plan is used to formally document and control the overall mining operations. The planning involves detailed processes to ensure optimal ore recovery, as the Mt Fubilan ore body is very complex.
Rock is drilled, blasted and excavated along 15 metre-high "benches" around the pit. The blasted material is excavated and loaded onto haul trucks using large shovels. Waste rock is transported to one of two waste rock dumps and released.
Ore is transported to large gyratory crushers that reduce it to a size of less than 200 millimetres. This crushed ore is conveyed to a primary stockpile at the mill.
