Background
AMC Coal Mines are operated by Adaro Energy Indonesia's PT Adaro Minerals Indonesia Tbk, in Lampunut, Murung Raya Regency, Central Kalimantan Province, Indonesia.[11][12]
The company has long proposed to increase production through the IndoMet Coal Project. AMC Coal Mines include five coal concessions, including PT Lahai Coal (LC), PT Maruwai Coal (MC), PT Sumber Barito Coal (SBC), PT Kalteng Coal (KC) and PT Juloi Coal (JC).
The concession areas are located in the Central Kalimantan and East Kalimantan province with a total area of 146,579 hectares.
As of 31 December 2022, two out of five subsidiaries, i.e. PT Lahai Coal (LC) and PT Maruwai Coal (MC) have been operational, while PT Sumber Barito Coal (SBC), PT Kalteng Coal (KC) and PT Juloi Coal (JC) were still in Operation Production phase. [13] While the mine was previously owned and operated by Adaro Metcoal Companies (AMC), in 2022, Adaro moved its metallurgical coal assets under PT Adaro Minerals Indonesia Tbk.[12]
As of December 2023, AMC's total coal reserves is 173.0 million tonnes and total coal resources is 975.6 million tonnes.[14]
A 2025 study published in Wahana Teknik Sipil: Jurnal Pengembangan Teknik Sipil examined haul road maintenance at PT Maruwai Coal's Lampunut site. The study found that in April 2023, dump truck cycle rates fell to 1.58 cycles per shift against a target of 2 cycles per shift, resulting in an estimated production loss of 26%, or 91,280 tons, attributed to declining haul road quality. Following the application of geocell and geopoll materials on a segment of haul road, researchers recorded an increase in the Coal Hauling Road Index from 83% to 91.23%, along with increases in average vehicle speed and monthly coal production.[15]

Coal Mine Boundaries and Methane Sources
Global Energy Monitor researchers have identified coal mine boundary/boundaries and potential sources of coal mine methane (CMM) for this mine. These research results can be used to drive CMM attribution and mitigation efforts, particularly when combined with remotely sensed methane plume locations and mine ownership data. Explore the results with the embedded map at the top of this page by clicking on the mine boundary polygon or the CMM placemarkers to reveal more details. A detailed description of this research can be found in Coal Mine Boundaries and Methane Sources. This data is also available as a downloadable companion dataset to the Global Coal Mine Tracker and the Global Methane Emitters Tracker.
