• Description:
  This testimony contains additional comments from NIOSH concerning the use of air coursed through the belt entry in terms of the impact of this modification on the design and development of mine ventilation systems. NIOSH indicated that, if two intake entries and two return entries are needed for adequate ventilation and escape, the mine will require five entries (two for intakes, two for returns, and one for the conveyor belt). NIOSH is not aware of any studies that indicate reducing the number of entries by placing the conveyor belt in either the return or the intake will consistently result in safer and more healthful conditions for the miners located underground. NIOSH does suggest that there are cases in specific mines where conditions may exist or develop that require modification of safety standards to provide the maximum protection to the miner and that these situations are best handled on a case by case basis using variances. Specific topics discussed include atmospheric monitoring systems, air velocity in belt entries, and respirable dust data (individual mine profiles, data inconsistencies, grouping by belt entry ventilation status, alternate dust data grouping, and respirable dust).
