In the March issue of North American Mining magazine, I asked how underground mines can achieve the best in mine ventilation. Key takeaways 👇 Maintaining consistent airflow and climate is an ever-moving target. As mines advance and work deeper, the system resistance increases, reducing volumetric flow if all other things remain equal. Hazardous gases require continuous monitoring and adjustment of ventilation systems to ensure safe levels and allow prompt re-entry after blasting to minimize downtime. Heat generated by mining equipment and mine depth significantly impact the climate. If a hot mine also struggles to maintain airflow, maintaining proper temperatures will be an uphill battle. Mining operations often do not implement a big enough fan to handle growing requirements as the mine advances. When designing a ventilation system, the design should meet maximum needs - and add some. Other factors to consider in ventilation design include mine size and layout, mining method and machinery, worker safety regulations, and the size and placement of ventilation shafts. Technologies like VFDs and geofencing allow mines to tailor the ventilation system for real-time conditions, cutting operating costs, ensuring a safe and comfortable working environment, and reducing a mine’s carbon footprint.
