  • Coal blending Wikipedia

    Coal blending is the process of mixing coals after coal has been mined to achieve quality attributes that are desirable for the coal’s intended application (e.g. steam generation, coking). The quality attributes that are most important in blending will differ from one mine site to another and also depend on how the coal seams vary in quality and their final intended use.Management of coal stockpiles, CCC/23 IEA Clean Coal Centre,Stockpile management is an important part of the coal handling process from mine to customer. Virtually all coal producers and consumers make use of stockpiles at their facilities, either to serve as a buffer between material delivery and processing, acting as a strategic stock against supply interruptions; or to enable coal blending to meet quality.
