Illumination is undoubtedly a vital aspect in mining operations. Properly designed and implemented lightning system would provide the mine workers with improved visibility and contribute to improved safety, productivity, and high level of morale. In this thesis a detailed survey has been carried out for a large-scale opencast coal mine. Survey data revealed that illumination levels at major parts of mine are below recommended levels. Detailed calculation showed that illumination cost is insignificant component of overall production cost. A little increase in production cost would bring the light level of mine up to desired standards. As per DGMS of India the mine lighting should be designed and installed with proper lamps and fixtures regarding height, orientation, spacing and reflectors or other accessories, to secure a uniform distribution of light on the work area for visual comfort and avoiding objectionable shadows, sharp contrasts of intensity, glare, light clutter (excessive groupings of light) and light pollution to prevent strain on the eyes of the workmen, work fatigue and medically defined stress. The following recommendations were proposed for consideration to improve the visual level in the workplaces. • Installation of 250-Watt lamps for the roadways so that the number of poles can be reduced resulting less cost for pole installation and more free areas for movement of vehicles. • Truck mounted illumination system can be used instead of fixed lighting system at the places which are vulnerable to damage caused by blasting. • The cabin lighting of HEMMs can be improved by installing proper luminaries..
