ABSTRACT:
A method for treating a mass of coal to suppress emanation of coal dust therefrom, the mass of coal having, prior to treatment, an exposed surface from which dust may emanate, comprises applying to the exposed surface an aqueous fluid comprising gelatinized starch to form a layer of the fluid over the surface and drying the layer of the fluid to form a crust over the surface.
