Abstract
A rock dusting composition composed of rock dust, e.g., limestone or other mineral dust, water, pumping aid, and polymer, e.g., acrylamide homopolymers, acrylamide copolymers, and combinations thereof, and a method for applying the composition to the surface of a mine. The composition has a water content and a polymer content sufficient to allow the polymer to (i) disperse water molecules within the composition and, upon drying of the composition, (ii) dissipate forming void spaces in the dried composition. The composition is useful for suppressing propagation of a flame and/or fire caused by ignition of coal dust and/or gas within a coal mine.
