Abstract
Methods for suppressing dust from the surface of dust-producing bulk materials such as coal are disclosed including preparing an aqueous suspension of cellulosic fibers dispersed in water and applying the aqueous suspension to the surface of the dust-producing bulk materials in order to suppress dust formation from that surface. The method can comprise use of the cellulosic fiber suspensions as a residual dust suppressant, as a dust suppressant coating for stockpiles of these bulk materials, or as an additive with other encrusting formulations such as latex.
