Coal Mining Process and Transportation
Mining and processing operations are all conducted internally by AKT, while barging & shiploading, and various ancillary mining services are outsourced.
Overburden Removal
Coal Minning
Handling
Hauling
Load to Barge
Barging
Overburden removal
- Stripping away topsoil and overburden to reach underlying coal
- Equipment - large excavators, dump trucks, dozers, graders
Coal minning
- Minning coal and transporting it to the CHPP
- Equipment – smaller excavators and haul trucks
Coal handling & processing plant (CHPP) (3-6 km from coal minning)
- Coal is processed via blending of ROM coal from external seams and crushing to arrive at a consistent product
- Coal quality is tested and monitored by in house and independent quality control personnel
- Stockpile capacity of 600 kt
- Equipment – 900 tpt crusher, stacker, wheel loaders, small excavators, dozers
Coal hauling 36 km from the CHPP
- Coal is transported to owner-operated Muara Tuhup port
- Hauling trucks – 90 x 20t, 13 x 35t haul trucks, and 40 x 30t
Load to barge
- Coal is loaded onto barges
- Stockpile capacity 1,600,000t
- Equipment – conveyor barge loader (2,400tph capacity), excavators, wheel loaders, dozers
Barging (562 km from Load to barge)
- Coal is barged down the Barito River to Taboneo, where it is loaded into ocean going vessels
- Danparan ISP: 350,000t stockpile base, capacity 1,000,000t
- The coal is transhipped from 220' - 230' (4000t) barges to longer 300' - 330' (8000 - 1000 t) barges at Damparan
