Experimental study on gas-heat characteristic scales during the entire coal spontaneous combustion-extinction-reignition process in sealed fire zones

Key Points

• Gas-heat characteristics significantly change during the spontaneous combustion process, impacting fire management.
• The study recorded key findings during the extinction and reignition phases of sealed fire zones, highlighting the critical dynamics.
• Using a experimental study design, researchers analyzed combustion behaviors across various sealed fire conditions.
• These findings emphasize the importance of understanding coal spontaneous combustion for improved safety in fire management.
