Application of Comprehensive Monitoring and Early Warning System for Spontaneous Combustion in Fully Mechanized Caving Face
Suitable natural ignition indicator gas and its critical value were proposed to address the potential danger of coal spontaneous combustion during coal seam mining.A comprehensive monitoring and early warning system for spontaneous combustion was designed,including an underground bundle tube monitoring system,a ground monitoring system and a chromatographic gas analyzer.The application results show that the system can play a warning role for the possible occurrence of coal spontaneous combustion during the recovery of easily combustible coal seams,providing technical support for safe and efficient recovery of easily combustible coal seams.
