摘　　要：新疆主要含煤地层为早-中侏罗世的八道湾组和西山窑组,陆相聚煤环境。煤层赋存受地质构造控制,聚煤作用主要发生在构造盆地内部。向斜和单斜为主要的赋煤构造,主要含煤盆地后期构造变形微弱,开采条件优越。以低阶烟煤为主,其次是中、高阶烟煤。煤类主要以长焰煤、不粘煤、弱粘煤为主;宏观煤岩组分以暗煤、丝炭为主,其次是亮煤。宏观煤岩类型依次为暗淡煤、半暗煤、半亮煤,光亮煤较少。煤层具有发热量高、水分含量低、灰分产率低、挥发分产率高、全硫含量低和低磷等特点。Xinjiang is rich in coal resources,and their mainly coal-bearing strata are Badaowan and Xishanyao Formation of Early-Middle Jurassic.To be controlled by geological structure,coal accumulation occurred mainly in the interior of the structural basins.Coal-bearing structures are often syncline and monoclinic instructural basins.Tectonic deformation of main coal-bearing basins is weak,and has a favorable mining conditions.There are mainly low-rank bituminous coals,followed in middle and high-bituminous coal.The coal type are mainly in the long flame coal,non-caking coal,weakly caking coal and so on.Lithotypes are mainly durain and fusain,followed by a bright coal.Macroscopic type mainly consist of dull coal,semi-dull coal and semi-bright coal.Xinjiang posses good quality coal resources with high calorific value,low moisture content,low ash production rate,high volatile matter yield,low total sulfur content,phosphorus content and so on.
