• Description:
  The U.S. Bureau of Mines conducted a study to assess the impact of a directional water spray system on a unique single-inlet dust scrubber on a low-profile mining machine. Tests were conducted in a full-scale model mine using a continuous mining machine. Tracer gas was introduced at the face and concentrations of the tracer gas were monitored at the face and in the return. Various parameters tested included mining position, depth of cut, brattice setback, and combinations of scrubber, and directional or symmetrical sprays. Results indicated that either water spray configuration improved the ventilation effectiveness of the scrubber by a factor of 2 to 3. Average face ventilation effectiveness (fve) values for all testing of the scrubber and directional sprays were 0.95, Versus 0.37 For a standard 20-ft blowing curtain without sprays. No fve values were less than the standard 20-ft blowing results. [Description provided by NIOSH]
