01/12/1999 This coal exploration has improved the understanding of the geology of the Indonesian coal deposits. The main economic coal deposits are of Eocene and Miocene to Pliocene age, which mainly occur in Kalimantan and Sumatra and were formed from peat deposits in an equatorial paleoclimate similar to that prevailing today. Some of these peats were domed peats, which grew

31/01/2009 The South Sumatra coal basin is one of the most important coal mining regions in Indonesia (Thomas, 2005). This basin is tectonically active and the coal in some parts has been affected by igneous activity. The basin formed in the Early Paleogene as a back-arc basin northeast of the Barisan Mountains.

The South Sumatra basin is among the most important coal producing basins in Indonesia. Results of an organic petrography study on coals from Tanjung Enim, South Sumatra Basin are reported. The studied low rank coals have a mean random huminite reflectance between 0.35% and 0.46% and are dominated by huminite (34.6–94.6 vol.%). Less abundant are liptinite (4.0–61.4 vol.%) and inertinite (0.2–43.9

Indonesian coal production has risen dramatically over the last 10 to 15 years, and Indonesia has emerged as one of the world’s largest exporters of coal, and the largest exporter of steam coal. This expansion has been at least partly triggered by a chaotic growth in licensing of new coal mines, following the roll-out of Indonesia’s decentralization agenda. This rapid and unstructured ...
