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