Coal blending can be performed at the mine site, on stockpiles, and in bins, bunkers, and silos (Arnold and Smith, 1994). There are a number of techniques that enhance the blending process, such as different ways of storage (circular stockpiles, longitudinal stockpiles), different procedures for stacking, and different processes of reclaiming.
