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 in excess of 60 million tonnes per annum in coming years.
Overburden removal is performed at the Tabang mine using a combination of hydraulic excavators/off-highway dump trucks. 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. We currently operate excavators of up to 300 tonnes with bucket capacity to 17.5m3 which have advanced features to drive productivity and efficiency. The coal is transported from the Intermediate Crushing Facility or Coal Pads with some of the largest hauling trucks in Indonesia with capacity up to 250 MT. The Tabang Project employs a number of Indonesia’s leading mining and hauling contractors including 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.
At Tabang project, coal is hauled from mining pits to temporarily located coal pads using off-highway dump trucks (typically 100 MT). From the coal pads, coal is loaded onto long-haul trucks used to transport coal to the Senyiur barge loading facility or the Muara Pahu barge loading facility.
Coal Haul Roads
Each mine has coal hauling roads with varied lengths to transport coal from the mine pit(s) to an ICF, coal pad and/or ports by using trucks with payload capacities ranging from 30 MT to 250 MT. The long haul road to our Senyiur barge loading facility has been asphalted to improve the operational efficiency and work safety. While the rest of the coal haul roads are covered with crushed stones to withstand all weather conditions.
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.
Senyiur Barge Loading 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 10,000 tonnes per hour of crushing capacity, approximately 1,500,000 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) can be loaded at this facility.
