Coal-mine explosions occur most often during the colder
months, October through March. MSHA’s annual winter
alert campaign draws attention to the hazards of cold weather. This year’s
campaign asks mine operators to “Knock Out the Risk” that winter weather brings
by taking specific actions to avoid workplace hazards. In underground coal
mines, mine operators are encouraged to ensure that there is adequate
ventilation in the mine, apply liberal amounts of rock dust, conduct frequent
and thorough examinations, and be familiar with emergency procedures that
prevent coal-mine ignitions and explosions.
