Coal can be stored in large quantities because of some necessities. Although stacking is generally done in open areas, there are also covered stack areas or completely closed coal silos. Produced coal is generally loaded in trucks or wagons by excavators and loaders to be transported to the storage areas.

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit area ( kg/ha).
