Designing cost-effective lighting system for surface mine projects

Abstract

The objective of lighting in mines is to provide good illumination, which improves the safe and efficient working environment. The artificial lighting is very much essential for the sustained production, to meet the ever-growing demand of the mineral industry. Haul roads within the pit are one of the critical areas in surface mines where lighting installations are not permanent due to regular movement of faces. Though the initial investment for the lighting is very less compared to total project cost, the annual cost is considerably high against the running cost of the project. The proper selection of lamps, reflectors, mountings etc., for particular type of work is very important for energy efficient lighting system, without compromising with the quality of light. A computer model has been developed to evolve a cost effective lighting system for surface mine projects. This model helps in assessing viability of various light sources, so as to achieve energy effective solutions. Properly designed lighting system can prove to be a very cost effective investment for the mine owner.
