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 …

The main chemical composition of CG is Al 2 O 3 and SiO 2, and CG can be classified into high Al/Si ratio CG and low Al/Si ratio CG [ 8 ]. Up to now, the CG with high Al/Si ratio is effectively applied on alumina production [ 9, 10, 11 ]. However, the CG with low Al/Si ratio hardly obtains large-scale application.

spontaneous combustion, the outbreak of fire without application of heat from an external source. Spontaneous combustion may occur when combustible matter, such as hay or coal, is stored in bulk. It begins with a slow oxidation process (as bacterial fermentation or atmospheric oxidation) under conditions not permitting ready dissipation of heat—e.g., in the centre of a …
