Abstract
Wind energy is a reliable renewable source of energy with significant technological advancements. However, recovering wind energy from waste and predictable sources remains untapped. Certain industrial activities emit pollutants while generating wind energy, presenting opportunities for cleaner energy utilization. This study investigates wind energy recovery from an underground mine’s exhaust through experimental research and analysis. It revealed a drop in wind velocity at −2.5162 Hz frequency as distance increased. This frequency predicted a wind speed of 7.67 m/s at 1 m from the exhaust fan in a real mine. Theoretical calculations show significant wind energy potential of 1031.31 kWh over 13 hours, which is equivalent to 79.3 kW. Realistic estimates suggest 55.51 kW wind power can be recovered, yielding 721.63 kWh. Compared with previous studies in the mining industry, recovery potential varies based on site-specific factors. The study shows a recoverable power percentage of 28% theoretically and up to 19.8% realistically, highlighting wind energy’s potential in underground mining. Moreover, the wind energy significantly contributes to the lighting system, enhancing energy efficiency. To optimize recovery, the ventilator fan system is upgraded, multiple fans are used, and optimizing the design is recommended. The study emphasizes continuous research and real-world implementations for energy savings. Utilizing wind energy effectively improves sustainability and reduces reliance on conventional sources, promoting a greener future for mining.
