Mine Life2037
Borneo Indobara coal mine (BIB) has been divided into five mining blocks: Kusan Girimulya (KG), Batulaki South (BS), Sebamban South (SS), Sebamban North (SN) and Pasopati (PP). Mining has been carried out in four blocks – Kusan (KG), Batulaki South (BS), Sebamban South (SS) and Sebamban North (SN).

KG Block still remains as the main operating block to support BIB’s enhanced production along with some production from SN and BS Blocks.

Deposit Type

  • Sedimentary


Summary:

The coal deposits found within the BIB coal concession area are located within the Asem Asem Basin of South-eastern Kalimantan. The Asem Asem Basin has been previously termed the Pasir or Asem Asem sub-basin to the larger Barito Basin.

The BIB coal concession area has a general inverted U shape which follows both limbs of a synclinal structure with an approximate north-northeast trending synclinal axis. The seams generally display shallow dips of around 20 degrees but dips can increase locally up to around 60 degrees. The entire Pasopati resource area, which is adjacent to obducted basement volcanic and ophiolites, exhibits dips of around 60 degrees. The increased dip in the Pasopati resource area is associated with increased coal rank, as seen from the fact that coals in the Pasopati area have in general higher calorific values compared to coals in the rest of the concession.

Structure within the area is relatively benign, with most of the significant faults in the area consisting of the north-east trending thrust faults that follow the general trend of the fold axes. Normal and block faulting is seen mainly in the basement (Pre-Tertiary) rocks (Panggabean, 1991). However, localised increase in seam dips have been observed in the coal models constructed for resource estimation purposes and this may be due to as yet un-mapped faults.

Kusan Girimulya (KG Block)
The deposit at KG Block contains approximately 54 modelled coal seams of which ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The mining schedule for the BIB concession blocks includes 4 existing open-cut mines, Kusan Girimulya (KG), Batulaki South (BS), Sebamban North (SN) and Sebamban South (SS) and a proposed open-cut mine at Pasopati (PP) with a target combined total coal production of 45 Mtpa from all the pits from the year 2023 onwards.

The mining operation in BIB is an open-pit mine using standard truck and excavator methods which are a common practice in Indonesia. Waste material is mined using hydraulic excavators and loaded into standard rear tipping off-highway trucks and hauled to dumps in close proximity to the pits or to in-pit dumps where possible. For the purpose of this Report, it is proposed that contractors will continue to be used for mining and haulage operations over the life of mine, and the unit costs used for the Reserve estimate reflect this style of mining.

Contractors are currently using truck and excavator combinations of 200-tonne excavator with 100- tonne trucks & 110-tonne excavator with 60-tonne trucks for waste removal whereas coal mining is being carried out by smaller size excavators (PC200-PC400 Komatsu excavators) with 30 tonne trucks. Coal from Kusan Pit is being hauled (about 20 km) to Port Bunati (Seaport owned by GEAR) for export to customers. The mining method can be described as a multi seam, moderate dip, open-cut coal mine using truck and shovel equipment in a combination of strip and haul back operations.
