    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

  • Effects of pyrite on the spontaneous combustion of coal

    Effects of pyrite on the spontaneous combustion of coal

    Sep 28, 2015 Pyrite has a significant effect on the spontaneous combustion of coal. The presence of pyrite can change the propensity of coal towards spontaneous combustion. The influences of various pyrite contents on the parameters of spontaneous combustion, such as index gases, temperature and released heat etc., were investigated in this study. Coal samples with different pyrite contents (0 %, 3
