Design and Development of Optimum Lighting Parameters for Haul Roads in Surface Coal Mines Using MATLAB Software Program - A Case Study

N.Lakshmipathy, Ch.S.N.Murthy, M. Aruna

In surface mines where natural light is not available especially during night hours artificial light is provided for better seeing, which facilitates increased production, reduce workers fatigue, protect their health, eyes and nervous system, and reduce accidents. One major problem in surface mine lighting is continuous changing of task place, including roadways. Because of this reason, it is difficult to provide any kind of long term permanent structure for illumination. Hence, the shifting of lighting installations at regular interval is very much necessary, so as to ensure required light level, as per the lighting standards specified by various regulatory bodies.
