Abstract
Three dust control systems for use in noncoal room-and-pillar mining were designed, fabricated, and evaluated. The first system, a hollow cutter bar, was designed to capture dust in the kerf at the cutting zone. The system was marginally effective in reducing dust levels because of the lack of control over other sources. The second system, a machine-mounted exhaust system, was extremely effective in capturing virtually all of the dust generated in the heading. The third system injected foam from an on-board generator through a channel to the cutting zone at the tip of the bar. Results showed that foam was equally effective when compared with the mine's current system.
