IMPROVEMENT IN PERFORMANCE OF MAIN VENTILATION FAN FOR MINE
Main ventilation fans are used in all the mines and they run continuously 24 hours a day and 365 days in a year. Any improvement in their performance can lead to considerable power saving. The basic principle for selection, operations, and related measures are discussed in brief in the paper. The contribution of different elements of mine fan on its performance is discussed in brief. The means to improve efficiency of a running fan is also discussed and the importance of saving even 1 kwh is elaborated. It is found that the cost of the energy saved may even permit a replacement fan to be procured in a few years time.
