Abstract:

This paper aims to determine the relationship between coal mine lighting level and work efficiency. On the basis of definition analysis of lighting and efficiency, combined with descriptive study of domestic and foreign institutions on indoor lighting and working efficiency, it finds out the general relationship between lighting level and working efficiency in mining. Meanwhile by experiment with man’s subjective feelings and efficiency changes as measures, it concludes that the increase of lighting levels can effectively improve work efficiency, reduce operation errors and that the reasonable lighting level for drillers is 1400 lx. It has referential value in the setting of coal mine lighting levels and newly-designed headlamp lighting levels.

Key words: Lighting Levels, Efficiency, Drilling Worker, Illumination
