Abstract: Aiming at the possible coal spontaneous combustion problem in goaf by “110 construction method” under “One intake airway and two return airway” ventilation modes. Using buried bundle tube monitoring and on-site measured data, combining software numerical simulation, analyzing the transport law of oxygen in goaf, we got the range of the spontaneous combustion “three zones” in goaf. The results indicated that the oxidized temperate zone in the goaf presents an inverted Inverted boot type distribution, It is necessary to focus on preventing the possibility of spontaneous combustion in the goaf along reserved laneway. The study determines that the minimum safe propulsion speed of the working faces is 1.48 m/d. The research results can provide references for the measures’ eimplementing to the comprehensive fire-prevention under similar conditions.
