Abstract: The eastern Inner Mongolia consists of five cities.The lignite resources are rich in the Eastern.The levels of coal spontaneous combustion reach I-II，belonging to the easy spontaneous combustion or spontaneous combustion.Coalfield fires in this area greatly affect the health of humans and results in the pollution of the environment and economic loss.After collecting the reports of the exploration and the papers of geophysics in the different 26 coal fires in Eastern Inner Mongolia，combining with the environment，geology and coals characteristics in this area，and also based on modern prospecting technology，the characteristics in remote sensing and geophysics in the Eastern are summarized.With the use of the exploration data，the boundary lines of coalfield fires are delineated and the model of coalfield fires is set up.Deep drills in each zone provide an accurate basis for the treatment of disaster zone.The experience of fire prospecting in the Eastern supplies a guide for the exploration of other coalfield fires in future.

Key words: Exploration, Coalfield fires, Lignite, Eastern Inner Mongolia
