贵州煤中氟的分布及赋存规律研究

Research on the distribution of fluorine in coal and the occurrence regularity

基于燃煤型大气氟污染的危害性及燃煤氟污染控制研究中存在的问题,结合贵州煤中氟含量分布特征以及六盘水、遵义等勘探区域的煤矿煤层样品与其对应煤矸石中氟的测定结果对比分析,对煤的变质程度与氟的关系、煤中氟与灰分的关系、煤中氟与碱金属的关系、煤中氟与氯等其它有害元素的关系等进行相关研究,探寻贵州煤中氟的赋存形态及其赋存规律,指出贵州省煤含氟量主要分布在50μg/g^180μg/g(平均含氟量135.6μg/g),贵州煤中氟主要以无机矿物形态赋存于煤中。

Based on the harmfulness of atmospheric fluorine pollution from coal combustion and the existing problems in fluorine pollution control research, and combining with the distribution of fluorine in Guizhou coal and the comparison analysis of fluorine in coal seam sample and corresponding fluorine in gangue in Liupanshui and Zunyi exploration area, the relationship between metamorphism degree of coal and the fluorine, the relationship between fluorine in coal and the ash content, the relationship between fluorine in coal and alkali metal, the relationship between fluorine and chlorine in coal and other harmful elements were researched, the occurrence form and occurrence law of fluorine in Guizhou coal were investigated, it was indicated that the fluorine in Guizhou coal is mainly in the range of 50 μg/g- 180 μg/g （average value： 135. 6 μg/g）, the fluorine is mainly existed as inorganic minerals state.
