| 摘 要： | 三马林达含煤区位于东加里曼丹省的东南部,在构造上属于加里曼丹面积最大的第三纪沉积库泰(Kutai)盆地。三马林达含煤区构造较简单,主要为宽缓的褶皱,褶皱轴向为北北东向。含煤区出露的地层自老到新有:第三纪中新世Tomp组、Tmpb组、Tmbp组、上新世Tpkb组和第四纪表土层Qa,其中中新世Tmpb组、Tmbp组和Tomp组地层中含有丰富的煤炭资源,这些地层中的煤层具有煤层多、埋藏浅、夹矸少、发热量大、稳定性好、开采条件好等特点。

| Abstract: | The Samarinda coal-bearing area,located in the southeast of East Kalimantan Province,belongs to the largest sedimentary basin in Kalimantan called Kutai Basin in structure.The Samarinda coal-bearing area’s structure is relatively simple,mainly formed by wide and gentle folds which the fold axis is NNE.The coal-bearing strata exposed ranging from old to new are: Miocene Tomp formation,Tmpb formation,Tmbp formation,Pliocene Tpkb formation and Quaternary alluvium Qa.Tmpb formation,Tmbp formation and Tomp formation are rich in coal resources,in which the coal seams have many seams and are shallow buried,little dirt band,large calorific value,high stability,good mining conditions and so on. |
