Coal gasification is the process of producing syngas (CO, H2, CO2, CH4 and H2O) from coal and water, air and/or oxygen. This can be used for electricity generation, converting syngas to gasoline and diesel, converting methane to LNG, etc. Mining in India has been very inefficient as mainly open cast mining is done.
Rat hole mining poses significant safety and environmental hazards. The mines are typically unregulated, lacking safety measures such as proper ventilation, structural support, or safety gear for the workers. Additionally, the mining process can cause land degradation, deforestation, and water pollution.

Coal Gasification is the process of converting coal into synthetic gas (syngas) which is a mixture of hydrogen (H2), Carbon Monoxide (CO), and Carbon dioxide (CO2). It is an in situ process in which oxygen is injected into the seam along with water and ignited at a high temperature, which causes the coal to partially oxidize into hydrogen ...
Process: Coal gasification is a process in which coal is partially oxidised with air, oxygen, steam or carbon dioxide to form a fuel gas. This gas is then used instead of piped natural gas, methane and others for deriving energy. Insitu gasification of coal or Underground Coal Gasification (UCG) is the technique of converting coal into ...
