摘要
Provided is an anti-oxidation agent that can be coated on the surface layer of a coal deposit (coal pile) to suppress further the amount of oxygen permeating to the interior of the deposit. This coal anti-oxidation agent contains an oil-in-water type resin emulsion, wherein the mean particle diameter of the emulsion particles is between 0.3 μm and 1.0 μm inclusive. Preferably, this anti-oxidation agent further contains a surfactant. An operator sprays the anti-oxidation agent over a coal deposit thereby forming a cemented layer with a high oxygen permeation suppressing effect on the coal deposit surface. Therefore, the oxygen in the atmospheric air is blocked from permeating to the interior of the coal deposit, enabling the prevention of coal oxidation.
