Abstract: In view of the goaf spontaneous combustion laws and causes analysis for Shaanxi Jianxin Coal Mine close distance coal seams spontaneous combustion and the study about hidden high temperature area identification difficulty and the harm, the high temperature point fire detection technology is used to judge coal spontaneous combustion and high temperature zone．By detecting the hole collecting gas analysis and validation, the fast control technology polymer-based colloidal is obtained, which successfully controls close distance seam group fire source high-temperature region under condition of complex air leakage．
