Dust Control for a Borer-Type Continuous Miner Using a Venturi Scrubber on a Transfer Car

  • Description:
    The Bureau of Mines, in conjunction with the Goodman Equipment Corp. and the Old Ben Coal Company, designed, built, and tested a transfer car to carry the major components of a ventilation system designed for use with a borer-type continuous miner. Dusty air was pulled through a 6,500-cfm venturi scrubber by a centrifugal fan mounted on the transfer car. The air passed through ducting installed on the miner and through flexible tubing between the miner and the transfer car. Field results indicated that this machine-mounted ventilation system achieved a respirable dust reduction of 66 pct at the miner operator position with the face ventilated using the exhaust mode. Since blowing-tube ventilation is presently practiced in some borer- type mining sections, the addition of a scrubber and machine-mounted fan could bring these sections into compliance with the 2-mg/m3 dust standard required by the Federal Mine Safety and Health Act of 1977. However, use of a transfer car attached to a borer-type miner posed handling problems and decreased productivity. An integral borer- mounted scrubber would avoid these problems.
