CDC - Mining - Rock Dusting Practices - NIOSH

Proper rock dusting practices have proven to be an effective means of preventing coal dust explosions. Rock dust (generally pulverized limestone dust) serves as a heat sink material that prevents or suppresses a propagating coal dust explosion through the absorption of thermal energy from the heated gases and absorption of radiant energy, which reduces the preheating of unburned coal
