Abstract: In order to tackle the problem relating to sluggish sales of the clean coal product of the Central Coal Preparation Plant, work is made on the product structure optimization schemes based on the actual production data recorded in 2015-2017. Comparison of alternative schemes shows that under prerequisite that an identical economic performance can be achieved, to appropriately improve the quality of metallurgical clean coal product can not only increase the calorific value of middling′s product but also be possible to cater to the marked needs for metallurgical clean coal, much facilitating therefore sales promotion.
