Abstract:

In order to study the properties of coking coal at different grain sizes,Zhaogezhuang fat coal,Hailing 1/3 coking coal,Mucun coking coal and Sangei lean coal are screened by 10mm,5mm,3mm and 1mm screens.Coal quality analysis and coal petrography analysis are carried out for each individual coal at different grain sizes.Influence of coal kind and coal grade to coking coal property is studied,which provides certain theoretical basis for selective crushing process of individual coals.
