A mine fire is an underground fire that occurs in coal mines or other types of mines. These fires can start from various sources, such as spontaneous combustion, electrical faults, or human activities. Once ignited, they can burn for long periods, sometimes for years, due to the presence of combustible materials like coal and methane gas. Mine fires pose significant hazards, including the release of toxic gases and the risk of explosions. They can also lead to the collapse of mine structures and threaten the safety of miners. Efforts to control or extinguish these fires can be complex and costly, often requiring specialized techniques and equipment.
