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.

Catalytic combustion of coal mine ventilation air methane

Underground coal mining is by far the most important source of fugitive mine methane, and approximately 70% of all coal mining related emissions are from underground ventilation air. Hence, research and development on mine methane capture, mitigation and utilisation should focus on methane emitted in ventilation air.

Coal waste Global Energy Monitor

Coal mining and coal combustion in power plants produce several types of wastes: The mining process itself produces waste coal or solid mining refuse, which is a mixture of coal and rock.; The mining process also produces liquid coal waste, which is then stored in impoundments.; Pollution control equipment used for coal combustion produces coal ash or fly ash, as well as flue-gas

Coal and Air Pollution Union of Concerned Scientists

Jul 28, 2008 CO 2 is also the main byproduct of coal combustion: nearly 4 grams of CO2 are produced for every gram of carbon burnt (depending on its type, coal can contain as much as 60 to 80 percent carbon). Methane (CH4) often occurs in the same areas that coal is formed, and is released during mining activities.
