Abstract: Based on a large number of literature, from the mechanism of burning coal seam, the principle and experimental research of Underground Coal Gasification, analogy to explore the feasibility of enhanced coal-bed methane recovery burning coal, and analyzed the technology in comparison of enhanced coal-bed methane recovery. The study found that burning coal technology which uses the combustion of coal seam gas, such as heat and CO2, can achieve the purpose of enhanced coal-bed methane recovery, is a new technology of enhanced coal-bed methane recovery. the development trend of the future should be carried out as soon as possible the fire simulation experiments of coal seam to improve coal-bed methane recovery, and it is necessary to do further research in the technology of mechanism and key control of burning coal.
