Abstract: “The main objective of this study was to assess the illuminance level in mines at different strategic locations as mentioned in statutory circulars by the Directorate General of Mines Safety (DGMS). This paper highlights the detailed field observations for assessment of the existing lighting condition of a mine and to quantify the effect of poor lighting on the safety and productivity of different Heavy Earth Moving Machineries. The second part of the work was to find out inherent problems in the illumination system of mines and design of most suitable illumination system for the haul roads by using DIALux software. The safety and health aspects were also included in this study. There were three mines namely Mine1, Mine2, and Mine3 chosen for field observation. The safety status of different locations inside the mines was examined by comparing illuminance levels at those locations with what was set by DGMS and by various typical issues faced by operators in those mines. The illuminance”
