| 摘 要： | 大竹坝井田位于呈北东向展布的松坎复式向斜南东翼之次级褶皱-乐坪背斜南东翼,含煤地层为上二叠统龙潭组(P3l),厚45.61~71.53m,平均厚61.10m,含煤层(线)2~6层,全区可采煤层一层(C3),局部可采煤层二层(C2、C4)。C3煤层具有低挥发份、中灰、中高硫、高固定碳、高熔灰分、高热值的特点。可作工业用煤、动力用煤、气化用煤和化工用煤以及民用等。井田以含煤地层相对较薄,可采煤层少,煤层厚度小,含煤率低为其特征。

| Abstract: | Dazhuba coal filed is located on the southeastern margin of a secondary fold,that is the Leping anticline,in the southeastern rim of the Songkan synclinorium that extends a NE direction,the coal-bearing beds belong to the Permian Longtan Formation in thickness of 45.61 to 71.53m,averaging 61.10m,there occur 2 to 6 coal-bearing layers and lines,in which one layer(C3) of minable coal layer exist in total area and two layers(C2,C4) of mineable layers exist locally.The C3 coal bed is characterized by low volatile,moderate ash,moderate-high sulphur,high fixed carbonate,high volatile,high heating value.The coal may be used to industry,power,gas produce,chemical industry and domestic.This coal filed is characterized by thin coal-bearing strata,few minable coal beds,thin thickness of coal beds and low coal-bearing ratio. |
