Abstract: The paper proposes gas analysis and temperature measurement combined method to monitor coal spontaneous combustion characteristics information. According to the coal spontaneous combustion characteristics information in goaf, the paper researches and develops the wireless ad hoc network temperature monitoring system for goaf. Integrated coal spontaneous combustion beam pipe monitoring systems and safety monitoring system, new spontaneous combustion multi-parameter monitoring system in coal mine goaf for monitoring mine goaf different position indicators gas and temperature real-time is established. The paper focuses on monitoring methods, systems integration, the design of key elements and monitoring programs. The study of the system provides a reliable basis for early detection of the floating coal spontaneous combustion risk in mine goaf, determining the degree of spontaneous combustion danger, and determining spontaneous combustion danger zone.
