The mining sector’s sustainability is contingent upon operational efficiency improvements. This has resulted in significant improvements in industrial energy efficiency, resulting in reduced emissions and resource waste. Indian mine ventilation fans were discovered to be energy guzzlers, paving the way for more efficient driving techniques. A thorough investigation of cost savings, energy savings, and pollution reductions associated with different airflow scenarios utilizing Tandsi underground coal mine ventilation networks were conducted. Two applications of ventilation-on-demand were investigated: dynamic and steady-speed reduction. Economic feasibility suggests that variable speed drives operating at medium voltage (3.3 kV) may be utilized in ventilation-on-demand systems. With the adoption of ventilation-on-demand solutions, a total yearly electrical energy savings of 1070618 kWh might be accomplished. The estimated cost savings are 119588 US $\$ $ , with a payback period of seven months on average. Emissions of greenhouse gases have been reduced by around 37% annually. A variable speed drive operating at medium voltage (3.3 kV) may be placed on the Tandsi mine ventilation fan to improve efficiency and decrease emissions. These audits identify underutilized resources that may be used to increase mining sustainability and profitability.
