Application of Thermocouple Thermometry and Bundle Tube Monitoring in Fire Prevention and Extinguishing in Coal Mine

Spontaneous combustion occurred many times in the goaf of E12606 Fully Mechanized Working Face of Cuijiazai Coal Mine. For reinforcing fire prevention and extinguishing management, thermocouple thermometry and bundle tube monitoring system had been laid in the goaf of E12606 working face. Through analyzing the measurement result (temperature and oxygen change rule), distribution regularities of three zones of spontaneous combustion and working-face propulsion speed had been determined for the goaf. This research provides technical support for Cuijiazai Coal Mine to prevent spontaneous combustion and arrange production rationally.
