A coal mine is a facility where coal, a fossil fuel, is extracted from the ground. Coal is formed from ancient plant material that has been subjected to heat and pressure over millions of years. Mining can be done through various methods, including surface mining and underground mining, depending on the location and depth of the coal deposits. Coal is primarily used for electricity generation and in industrial processes. It plays a significant role in the energy sector, but its extraction and use can have environmental impacts, such as air pollution and greenhouse gas emissions. Efforts are ongoing to transition to cleaner energy sources, reducing reliance on coal and other fossil fuels.
