A surface mine which covers several square kilometers of land and where mining operations are carried out round the clock, systematic artificial lighting is necessary for providing safe and efficient working environment. Major problem in mine lighting is continuous changing of task place and poor surrounding reflectance. This signifies the scientific design of illumination system, which is very important for good vision, so that individuals may work therein with reasonable comfort. Also, advances in lighting technology have shown that there is a tremendous scope for energy conservation in lighting systems. Consequently, cost effective lighting installations have become synonymous with energy efficient lighting systems. Hence, a scientific approach in the illumination design would contribute to efficient lighting without much addition to the total mining project cost. In this book, design of illumination system for mine haul roads is demonstrated based on testing of large number of luminaries, which are very widely used in the mines. The results of the study given in this book provide guidelines for design of lighting system for mine haul roads, for similar operational conditions.
