摘　　要：通过对煤田勘探的煤心煤样测试数据的统计分析,结合收集到的胜利煤田研究资料,初步探讨了胜利煤田煤中氟的含量特征以及赋存状态,结果表明:胜利煤田主采的5^#、6^#煤中氟含量均高于全国煤及世界煤中氟含量的平均值,属于高氟煤;煤中氟含量与与水分无明显的相关关系,与煤灰分产率具有良好的正相关,且与煤中矿物Al2O3,SiO2,TiO2含量强烈正相关,与Sp,d含量具有明显的相关性,推断氟主要以与含Al、Si、Ti矿物,与黄铁矿结合也是煤中氟可能的赋存方式。Through statistical analysis of coal core sample tested data during coalfield exploration,combined with acquired research data from the Shengli coalfield,initially discussed fluorine content features and hosting state in the coalfield.The result has shown that coal fluorine content in main coal seam Nos.5 and 6 is all higher than average of other Chinese and world coals,belongs to high fluorine coal.Coal fluorine content and moisture without obvious correlativity,but has positive correlation with coal ash yield,and strong positive correlation with content of minerals Al2O3,SiO2 and TiO2 in coal,as well as obvious correlation with coal Sp,d.It is deduced that fluorine mainly combined with minerals containing Al,Si,Ti,and combined with pyrite also is a possible hosting mode of coal fluorine.
