Ventilating air to a continuous mining section, whether blowing or exhausting, is the primary means of protecting workers from overexposure to respirable dust. Proper application of water spray systems, ventilation, and mechanical equipment (scrubbers) provides the best overall means of .

    Continuous Mining Machine Conveyor System Sound Power Levels In order to reduce operator overexposure, noise generated by the continuous mining machine conveyor system must be abated. Noise produced by this system is due to the. Effect of water sprays for respirable dust suppression with a research continuous-mining machine.

Causes of water spray nozzle clogging on coal mine face machines were investigated and determined. This led to the design, development, and subsequent successful field testing and demonstration of a non-clogging water spray system.

The non-clogging system was installed on three different continuous-mining southlakes-cottages.com: H.E. Harris, R.E. Segien. CONTINUOUS MINER SPRAY CONSIDERATIONS FOR OPTIMIZING SCRUBBER PERFORMANCE IN EXHAUST VENTILATION SYSTEMS John Organiscak, National Institute for Occupational Safety and Health, Pittsburgh, PA.

Timothy Beck, National Institute for Occupational Safety and Health, Pittsburgh, PA. Abstract. A majority of continuous mining machines employ a water. A majority of continuous mining machines employ a water spray system and a machine mounted flooded-bed scrubber to suppress and capture dust during coal mining.

These machine mounted dust control systems must be designed to function within the localized face ventilation system at the mining section to control both dust and methane.
