    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.

    However in coal mines, coals spoken of as being liable to spontaneous combustion are those coals which will develop to an open fire under specific conditions. Many seams will not reach this point. When spontaneous combustion occurs, there is an initial stage where the temperature is rising but no burning in the normal sense is taking place.
