Tabang / Pakar Mine
The Tabang / Pakar mines are located approximately 180 kilometres Northwest of Samarinda and are located in the Kutai Kartanegara Regency of East Kalimantan. The resource consists of 12 Mining License Permits (Izin Usaha Pertambangan) that contain a significant deposit of low-ash low sulphur sub-bituminous coal. The mine has significantly ramped up in recent years is the largest in this regency with plans to increase production to approximately 50 million tonnes per annum in coming years.
- Mining Operations
Overburden removal is performed at the Tabang mine using a combination of hydraulic excavators/off-highway dump trucks and the dozer push mining methodologies. Bayan is the first coal mining company in Indonesia to employ dozer push on a commercial scale. The deposit contains a number of seams, with the main seams typically thick (averaging 14-15 metres and up to 34 metres) and gently dipping (< 5 degrees). Coal is mined using fleets of hydraulic excavators/off-highway dump trucks and hauled to either the Intermediate Crushing Facility or a coal pad. The Tabang Project employs a number of Indonesia’s leading contractors including Petrosea, Bukit Makmur, the Mandiri Group and the Karunia Group.
- Intermediate Crushing Facility
The Intermediate Crushing Facility (ICF) is owned and operated by the Bayan Group and is located near to the mining locations of the PT. Fajar Sakti Prima and PT. Bara Tabang concessions. The ICF has two crushing and screening lines with capacity of 500 tonnes per hour and 1,500 tonnes per hour, respectively, and a total stockpile capacity of 720,000 tonnes.
- Coalpad 2
Coal Pad 2 is owned and operated by the Bayan Group and is located near to the mining location of the PT. Bara Tabang concession. Coal is transported from the mining pit in 100 tonne class off-highway dump trucks to this location and deposited in Run of Mine (ROM) stockpiles. The ROM coal is then crushed in one of two crushers with a combined capacity of 3,000 tonnes per hour before being deposited in one of twenty truck loading hoppers that are capable of loading up to ten trucks at a time. Dual-trailer coal haulage trucks in the range of 200 – 220 tonnes are then loaded from the hopper with loading times of typically less than 20 seconds.
- Gunung Sari Barge Loading Facility
The Gunung Sari jetty is owned and operated by the Bayan Group and located near the village of Gunung Sari on the Belayan River in the Kutai Kartanegara regency, East Kalimantan. The jetty consists of approximately 700,000 tonnes of total stockpile capacity and a barge loader with a capacity of 2,000 tonnes per hour. Barges of 3,000 metric tonne capacity (230 feet) are able to be loaded at this facility.

The Senyiur jetty is owned and operated by the Bayan Group and is located near the village of Senyiur on the Kedang Kepala River in the Kutai Timur regency, East Kalimantan. The jetty consists of 3,000 tonnes per hour of crushing capacity, approximately 1,000,000 tonnes of total stockpile capacity and three separate barge loaders with a combined capacity of 12,000 tonnes per hour. Barges of 7,500 metric tonne capacity (300 feet) are able to be loaded at this facility.
