Handbook for dust control in mining. Pittsburgh, PA: National Institute for Occupational Safety and Health, 2003 Jun; :83-96
In this chapter: ore pass dust control; drill dust control; blasting dust control; conveyor belt dust control; transfer point and crusher dust control; roadheader dust control and how much ventilation air to use. This chapter discusses respirable dust control in underground hard-rock mines. These mines use a wide variety of extraction methods, but they have many common dust sources and dust control needs. Ore passes, drills, blasting, conveyor belts, transfer points, crushers, and load-haul-dump operations can be major sources of dust. Roadheaders, which are sometimes used in hard-rock mines, produce dust in large quantities. For the most part, dust in hard-rock mines is controlled with ventilation air, water sprays, and dust collectors. It is also important to prevent dust from getting into the air in the first place. Good dust control practices will reduce overall mine ventilation requirements.
