摘　　要：Kotabara井田位于南加里曼丹省南部,属于古近系盆地之一的Asam-Asam盆地的一部分。井田构造简单,主体为单斜构造。井田内揭露地层由老至新为新生界古近系(E)、新近系(N)和第四系。其中古近系始新统丹戎组(Tanjung)中段(T_(2))为含煤层段,地层中含有丰富的煤炭资源,SL1、SL2、SL3U、SL3/4为主要煤层。主要可采煤层具有埋藏较浅、夹矸少、发热量高、稳定性好、开采条件好等特点。The Kotabara mine field is located in the south of South Kalimantan Province,it is a part of the Asam-Asam basin which belongs to one of the Paleogene basins.The geological structure in the mine field is simple,its main body is monocline structure.The strata uncovered in the mine field are Cenozoic Paleogene(E),Neogene(N) and Quaternary from old to new.Thereinto the middle part of Tanjung Formation(T_(2)) of Eocene in Paleogene is a coal-bearing strata,there are rich deposits of coal in the strata,SL1,SL2,SL3U and SL3/4 are the main coal-seams.The main minable coal seam has the characteristics of shallow burial,less gangue,high calorific value,good stability and good mining conditions.
