Spontaneous combustion in coal mines and coal stacks is recognized as the major hazard in terms of safety and economy. Due to increasing demand of coals, it is becoming obvious to go for mining of thin coals lying under difficult geo-mining conditions which further aggravates the above problem. It is therefore essential to study the spontaneous heating characteristics of coals considering the coal chemistry and also the geology of coal. Till date, researchers have made attempts to identify the genesis as well as for finding cost-effective remedial measures but no concrete solutions have been established.. In most parts of a mine,  coal oxidation takes place, the air flow is sufficient to remove the heat produced and prevent development of  heating. The danger lies in areas where there is sufficient air flow to provide supply of oxygen but insufficient to provide enough cooling to prevent heating. Such locations may be in areas of fractured coal with a pressure differential across them in piles of cut or broken coal placed in unventilated locations and particularly in goaves.

The present course will focus on assessing the spontaneous heating liability of coals using different experimental methods, updating research and development activities being carried out in India and abroad on prediction of sponcom as well as deal with scientific approaches for prevention and control of mine fires.
