Coal analysis can accurately determine from the microscopic to the case of coal and mixed coal ratio, through the blending reflectance, Coal analysis can accurately determine from the microscopic to the case of coal and mixed coal ratio, through the blending reflectance, maceral content and the percentage ratio of measured to guide coking production, coke porosity prediction by measuring the quality of coke. According to the results of coal analysis to guide the rational into the pile of coal plants, coal for the coal fields of information and resources to provide guidance to procurement management.
