The method is mainly applied to the fields of comprehensive dust prevention and fire prevention in coal mining, dust suppression of strip mine pavements, flame retardation of port coal piles, dust suppression and the like. The final result is also a solid spray applied to the above mentioned surfaces that are boring in the field as dust suppressant and flame retardant. The flame-retardant and fireproof effects and effects of the liquid cannot be reflected. The inventors of the present invention have made intensive studies and experiments to further exert the flame-retardant and fireproof effects of the aqueous solutions of calcium chloride and magnesium chloride, and have made the object of the present invention.
