Coke is one of the important materials of metallurgy,which will not change in the future for a long time.It is of great theoretical value and practical significance to analyze and control the quality of coal that is used as raw materials in coking enterprises.But due to the complexity of the molecular structure of coal,it can not be foreseen to control the quality of coal.Therefore,for the accurate interpretation of coking coal and its relationship with the coke properties,it is important to master the relation between the fluorescence properties of the coal and the quality of coke on coking..This paper makes a detailed analysis and research on the research progress of resources of coking coal,conventional properties of coal and fluorescence properties.Choosing 21 kinds coal of different degree of coalification in topics,this paper makes40 kg coking oven test and crucible coking test to study in coal quality and fluorescent properties of coal,and obtains the relationship between properties of coal and coke quality.This paper discusses the influence of coal's fluorescence on caking index G,plastometer indices Y,Giseeler fluidity log MF,Audiberts arnu dilatation b,Coke optical organization,coke pore structure,Resistance tobreakage M40,wear resistance M10,Reactivity CRI,Strength after reaction CSR,Micro strength MSI and structural strength SSI through the coal three-dimensional fluorescence and fluorescence ofcoal chloroform extract.Under the similar reflectivity and rock components,with the increase of fluorescence intensity,G gradually increased,Y gradually increased,log MF gradually increased,b gradually increased,coarse grained mosaic gradually increased,fine grained mosaic gradually decrease,various homosexual gradually decrease,flow shape gradually decrease,M40 gradually increased,M10 gradually decrease,CRI gradually decrease,CSR gradually increased,MSI gradually increased,SSI gradually increased.
