Exploration of Illumination Concepts for Underground Coal Mines.
NTIS: PB/212-070 Available for Reference At Bureau Libraries :313 pages
The lack of adequate area lighting in the working places of underground coal mines has been a contributing factor to mine accidents involving damage to equipment and serious injury to personnel. This report describes two prototype lighting systems to demonstrate the feasibility of interim lighting equipment and recommends long-term solutions for working place lighting in underground coal mines. Lighting requirements for high and low coal seams were evaluated and found to be similar, eliminating the necessity for unique lighting systems based on coal seam height. A prototype man-portable area lighting system was developed to meet the operational requirements of conventional mining. A prototype machine-mounted lighting system was developed to meet the operational requirements of mechanized mining. An illumination system concept using portable area lights for entry lighting and roof-support mounted lights for face lighting was recommended to meet the operational requirements of longwall mining. Unusual operational conditions would require both machine-mounted and portable luminaires.
