26/8/2020 Fire in an underground coal mine is hazardous because of the confined space, possible effects on the ventilation system, and limited and long evacuation routes. Mine fires, in conveyor belt entries, can produce smoke and high levels of toxic gases that are carried throughout the mine by the mine ventilation system.
It takes as little as 1.4 kg (3 lbs) of pulverised coal in 28 m3(1,000 ft3) of air to form an explosive mixture. Since a large boiler burns over 40 kg (88 lbs) or more of coal per second, the safe burning of pulverised coal necessitates strict adherence to planned operating procedures.
It is important to remember that a mill fire, whether it be flaming, smoking or smoldering coal inside the mill means a mill explosion could be occur at any time. Any burning or smoldering material inside the mill can evolve into an explosion because they provide an ignition source if the air to fuel (coal) ratio is elevated or higher than desired.
