Current practices of protection against coal dust explosions propagating through mines are examined and found to be basically methods of cooling flames below the temperature limits for flame propagation. Such is the case with rock (stone) dusting and with passive barriers (extinguishant dispersed by the explosion) using rock dust or water. Chemical fire extinguishants, such as sodium and potassium compounds used in recent research seeking to develop triggered barriers (extinguishant dispersed by a contained energy source on signal from a flame detector), do not appear to have a great advantage over thermal quenching agents.
