• Description:
  A literature search was conducted to identify current light-control technology and hardware that may be applicable on underground lighting systems to minimize disability and discomfort glare. No research dealing specifically with mine lighting was found, but abstracts on research considered potentially applicable are included in the report. Information on several commercial light-control products for use in controlling glare are also included. Vision tests conducted on 137 mine personnel to determine their discomfort and disability glare sensitivity indicate their sensitivity to disability glare is about the same as the general population. Miners' sensitivity to discomfort glare is 40% greater coming off- shift than when going on-shift. Tests on currently available mine lighting hardware showed none were satisfactory with respect to glare potential. Reflectivity measurements showed the average reflectivity of mine surfaces were 4.2% For coal, 8.3% For the roof, and 4.0% For the floor. [Description provided by NIOSH]
