摘　　要：BARA煤矿位于苏门答腊岛西北部,属印度尼西亚的亚齐特别行政区NAGAN RAYA县。在构造上属印尼五大沉积盆地之一的西亚齐盆地,该盆地构造较简单,发育宽缓的褶皱,断层不发育。盆地内煤炭资源丰富,含煤地层为新生界新近系上新世Tutut(都独)组,聚煤期发育河控-浅水三角洲沉积体系。区内工程地质、水文地质条件简单,适合露天开采。主要可采煤层为C1、D1煤层,属特低灰至中灰、特低至中硫、特低有害成分,高热值的优质褐煤。BARA Coal Mine is located in the northwest Sumatra which belongs to NAGAN RAYA county, Aceh Special District, Indonesia. It is one of the five big sedimentary basins in Indonesia, called Westen Qiya basin with simple structure. It is rich in coal resources and the Coal - bearing strata being Cenozoic Neogene Pliocene Tutut group. The river controlled delta deposifional system was developed in in shallow sea in coalforming period. It is suitable for open pit mining because the engineering geology, hydrogeological conditions is very simple. In BARA Coal Mine, the main mining coal seam is the C1 and D1 seams, which are high- quality lignite with low to medium ash content, low to medium sulfur content low harmful components content and high calorific value.
