Abstract: 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.
Key words: fully mechanized caving face; monitoring and early warning system; spontaneous combustion
