摘　　要：为扩大特殊煤种和稀缺煤种的利用途径,以树皮煤、太西煤和小发路煤为试验煤样,通过工业分析、元素分析和显微组分分析等研究了3种煤样的宏观煤岩特征和煤属性性质,并对煤炭质量进行分级。结合煤样基本性质和工艺性能等提出3种煤的合理利用途径。结果表明,树皮煤属于高~特高挥发分、低灰和中高~高硫煤,太西煤属于特低挥发分、特低灰和特低硫煤,而小发路煤属于特低挥发分和特低灰煤。太西煤可用于生产超低灰纯煤,制备炭石墨复合材料、活性炭、优质铸造型焦等;小发路煤具有良好的加工利用前景,可用于生产活性炭、炭素、碳化硅、阴极炭块和高炉喷吹等;树皮煤应做到综合利用,加氢液化是一条可行之路。In order to expand utilization ways of typical and scarce coal,the coal macro petrological characteristics and properties of Bark coal,Taixi coal and Xiaofalu coal were investigated by proximate analysis,ultimate analysis and maceral determinate,etc. Furthermore,these coals were graded according to the relatively national standards. The results showed that the Bark coal was characterized by superhigh and high volatile matter,low and medium- low ash,medium- high and high sulfur. The Taixi coal was featured by ultra- low volatile matter,super-low ash,ultra-low sulfur and the Xiaofalu coal was ultra-low volatile matter and ultra-low ash.The Taixi coal was able to be used in the production of ultra-low clean coal,carbon- graphite compound materials,activated carbon and high quality foundry coke,the Xiaofa coal could be used in the production of activated coke,carbon,silicon carbide,cathode carbon block and blast furnace PCI coal.The Bark coal should be utilized comprehensively and liquefaction was a good choice.
