贵州安龙县青龙台板燕煤矿煤质特征分析研究

ANALYSIS AND RESEARCH ON COAL QUALITY CHARACTERISTICS OF QINGLONGTAI BANYAN COAL MINE IN ANLONG COUNTY,GUIZHOU PROVINCE

基于青龙台板燕煤矿勘探成果资料,分析了井田内可采煤层的煤质特征及其变化规律,并对井田内煤的工业用途进行探讨。结果表明:宏观煤岩层以半暗-半亮型煤,有机组分为镜质组与惰质组,惰质组以氧化丝质体为主,其次为半丝质体,偶见火焚丝质体;可采煤层总体属中灰煤,高硫,特低挥发分,较低软化温度,低磷,四级含砷,特低氯,高氟,中至中高发热量煤层。

Based on the data of exploration results of Banyan Coal Mine in Qinglongtai,the coal quality characteristics and variation rules of mineable coal seams in the mine field were analyzed,and the industrial use of coal in the mine field was discussed.The results show that the macroscopic coal strata are semi-dark to semi-bright coal,and the organic groups are divided into vitrinite and inertinite.The inertinite is mainly oxidized fusinite,followed by semi-fusinite,and occasional fire burning fusinite.The recoverable coal seam belongs to medium ash coal,high sulfur,ultra-low volatile matter,low softening temperature,low phosphorus,four grade arsenic,ultra-low chlorine,high fluorine,medium to medium and high calorific value coal seam.
