[0002] Coalfield fire is one of the disasters faced by coal mining countries in the world. Coalfield fire areas not only burn a large amount of coal resources and make a large amount of coal resources unavailable for mining, but also produce a large amount of toxic and harmful gases such as CO, CO2, SO2 and harmful chemicals such as mercury and selenium that pollute soil and water resources, causing serious damage to the fragile ecological environment in the west. Coalfield fire areas have large combustion volumes and high temperatures, and there is a huge amount of heat in the fire areas. According to statistics, about 1 billion tons of coal are burned by underground coal fires every year in the world, generating about 1000GW of energy, which is equivalent to 2.5 times the total energy produced by 500 nuclear power plants in the world, and exceeds the energy produced by hydropower generation by nearly 100GW. If the heat extraction and treatment of coalfield fire areas are combined, that is, the purpose of "green" treatment of fire areas is achieved by extracting and utilizing the heat in the fire areas, the organic unity of fire treatment, energy utilization and environmental protection can be achieved. The methods of heat energy extraction in coalfield fire areas mainly include the use of heat conduction pipes, heat convection of heat media, temperature difference power generation technology, and distributed coalfield fire area heat energy extraction new power generation technology.
