The invention provides a method for identification of underground coal fire center, in order to improve the governance effect of existing technology in coal. The method includes: obtaining the coal surface status information, the surface state including surface cracks, ground subsidence and ground breaking and fire and heat wave; according to the occurrence of coal surface conditions as follows, determine the surface with coal combustion has formed a center: the form of fissure group, most cracks form combustion ventilation system. Ground fire or heat wave, and ground subsidence, the degree of fragmentation is higher than that of the surrounding ground coal.
