• Description:
  The canopy air curtain device is designed to reduce the level of respirable dust exposure to a continuous mining machine operator in an underground coal mine while having a minimum effect on the operator safety, mobility, and comfort and being compatible with mining equipment. Various concepts were evaluated by means of laboratory tests. One 200-cfm device was selected and tested on various mining machines at underground sites. The percent reductions over the ambient dust concentrations were from 30 to 70 percent, depending on the amount of time the operator spent under the air curtain. [Description provided by NIOSH]
