May 12, 2020 In China, the connection between coal utilization and environmental pollution has been increasingly evident due to the rapid growth in energy consumption. Clean coal technology CCT is one of the effective methods to address coal-associated pollution. However, CCT needs the practical and theoretical support of clean coal geology CCG. In this paper, a new definition of CCG is proposed,

Knowledge about coal must be obtained from coal geology and coal geochemistry two important fields in coal science. In this short article, the origin of coal, coal geology, coal classification, coal exploration and mining, coal geochemistry, and coal mineralogy are introduced.
Dec 01, 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.
