As soon as coal is mined and exposed to oxygen, oxidation begins. As long as the heat generated from oxidation is able to dissipate, the temperature of the coal will not rise and spontaneous combustion is not a concern. However, if unable to dissipate, that heat can build until temperatures necessary for ignition are reached. SponSuppress TC2 (Total Coal Control) formulation combines the ability to control sponcom and offer dust control with industry leading freeze conditioning performance.
