Spontaneous Coal Combustion Part 1: A Burning Mystery ...

India has the largest concentration of coal fires, and it is estimated that 80% of those fires started due to spontaneous combustion. Indian coal fires were first documented in coal fields located in Raniganj back in 1865. In addition, mines in Jharia, Jharkhand are famous for their rich coal resources, but records show nearly 70 fires have been burning for over 100 years dating back to 1916.

how to protect coal from spontaneous combustion

Spontaneous combustion results from self-heating which is caused mainly by the oxidation of coal and other carbonaceous materials. If the heat generated by this reaction is trapped, such as in a spoil pile, the temperature of the material will begin to rise and if unchecked may ultimately ignite; i.e.
