West Virginia coal is ranked as a bituminous coal whose bulk density varies between
42 and 57 lb/ft

. The bulk density of broken coal varies according to the specific grav-
ity, size, distribution, and moisture content of the coal. The amount of settling when
the coal is piled also affects the bulk density. A support bracket for the hydraulic lift
on a dump truck was made of mild steel angle with nomina ...
