乌达矿区主采煤层煤相特征与煤的可选性

CHARACTERISTICS OF COAL FACIES AND WASHABILITY OF THE MAIN MINABLE COAL SEAMIN WUDA COAL MINING AREA

    摘要
  • 摘要: 对内蒙古乌达矿区主采煤层9煤层的煤岩学特征和煤相进行了分析,用煤样密度组成的煤岩学方法讨论不同煤相煤的可选性。研究表明,相同煤相不同煤的可选性相似,聚煤环境决定了煤中矿物的含量和赋存状态,同时也决定了煤的可选性。高位泥炭沼泽形成的煤可选性好,而低位泥炭沼泽形成的煤可选性差。

     

    Abstract: The characteristics of coal petrology and coal facies of the main minable coal seam No.9 areanalyzed. The washability of coal in different coal facies is discussed using the density distribution of coal samples from Wuda coal mining area, Inner Mongulia. The research results indicated that the washabilities of coal in same coal facies are similar, the sedimentary environment controlled the quantity and distrbution of minerals, and thus controlled the coal washability. The washability of coal deposited in high peat bogs is better than that deposited in low peat moors.
