摘　　要：地瓜二井田位于贵州省普安县城南,含煤地层位于龙潭组中段上部。17_(-2)号煤层厚度0.47~13.98 m,平均3.58 m,全区可采,宏观煤岩类型为半亮型,微观煤岩类型为微镜惰煤。煤质特征为中灰,低挥发份、中高固定碳、中高硫、低磷、特低级砷、低氟、高热值的三号无烟煤,可作为民用、化工等用煤。17_(-2)号煤层是资源量最大的主要可采煤层,分析研究其煤质特征及工业用途,对矿井的建设以及煤炭开发利用具有重要的意义。Digua No.2 Minefield is located in the south of Pu＇an County, Guizhou Province. The coal-bearing strata are located in the middle of the middle section of Longtan Formation. 17-2 coal seam thickness of 0.47 ～ 13.98 m, an average of 3.58 m, the region can be adopted, the macro-coal type for the semi-bright type, micro-coal type for the micro-mirror lime. The coal is characterized by gray, low volatile, medium and high fixed carbon, medium and high sulfur, low phosphorus, special low arsenic, low fluoride, high calorific value of anthracite, can be used as civilian, chemical and other coal. The coal seam of No.17-2 is the main recoverable coal seam with the largest amount of resources. It is of great significance to analyze and study its coal quality and industrial use, and it is of great significance to mine construction and coal development and utilization.
