A coal miner is a worker who extracts coal from underground mines or surface mines. Coal is a fossil fuel that is used primarily for electricity generation and steel production. Miners use various tools and machinery to dig and transport coal, often working in challenging and hazardous conditions. Coal miners typically undergo training to ensure safety and efficiency in their work. They may work in teams and are responsible for maintaining equipment and following safety protocols to prevent accidents. The job can be physically demanding, requiring strength and stamina, as well as knowledge of geology and mining techniques.
