✦ Synopsis

When fresh coal is exposed to air it undergoes exothermic chemisorption of oxygen which is followed by formation of surface oxides and to some extent oxidation of the coal, resulting also in emission of various gases (the most prominent of which being CO,, H,O and CO). Large bituminous coals stockpiles that are stored for long periods may develop hot spots due to autogenous heating. In extreme cases spontaneous
