Ventilation Control of Coal Dust in Mines 1980 MSHA

This 1980 MSHA film clip demonstrates various ventilation techniques to control dust including the use of proper face ventilation to effectively remove airborne dust. Over the years, some consensus has emerged on the best dust control practices. The NIOSH Publication, Handbook for Dust Control in Mining summarizes those practices and is available at http://www.cdc.gov/niosh/mining/pubs/... . This handbook describes effective methods for the control of mineral dusts in mines and tunnels for different kinds of mines and mining equipment. This includes underground coal and hard-rock mines, as well as surface mines, stone mines, and hard-rock tunnels. Dust control methods described are practical and cost-effective for most mine operators. This is clipped from the 1980 Mine Safety and Health Administration (MSHA) film, Coal Dust: Hazards and Controls.
