龙山燃煤煤质特征及原煤可选性研究

Characteristics and Floatability of Longshan fuel coal in southwest Guizhou province

    摘要
  • 摘要: 对龙山燃煤进行了宏观鉴定、镜下鉴定、工业分析、筛分试验及浮沉试验。结果表明, 龙山燃煤煤岩类型属于光亮煤, 大多数燃煤为硫分、灰分都较高的气肥煤, 原煤可选性为中等可选煤。

     

    Abstract: The Longshan fuel coal is studied through macroscopic examination,microscopic identification,proximate analysis,screening test,floating and sinking tests.The results show that the lithotype of the fuel coal ranges to bright coal and gas-fat coal in rank;the coal is characterized by high sulfur and ash contents.The floatability of raw coal is in the middle degree.
