The geological setting of Indonesian coal deposits ...

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

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

Contemporary coal dynamics in Indonesia - SEI

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 ...
