Development of air leakage in goaf and residual coal self-ignition Characteristics Study on the spontaneous combustion of residual coal in goaf in the early prediction, prevention and control management has very important significance. Based on the mining coal working surface pressure energy distribution and Sign gas detection of Nanzhuang coal mine working face within the airtight air leakage condition and the O2, CO, CO2, C2H6, C2H4, C3H8 and other Sign gas concentration variation, identified 4601, 8808 lane closed walls within Coal body broken belt of spontaneous combustion danger area and its morphology. According to the spontaneous combustion of residual coal in goaf features from strengthening ventilation management, strengthening the gas and temperature detection, perfusion of three-phase foam developed a comprehensive system for the prevention and control of coal spontaneous combustio
