Italian It should go without saying the integral role ventilation systems play in supporting the safety of underground mining operations. Primarily, these systems fulfil three primary functions:
- Supplying fresh air to miners,
- Diluting hazardous and particulate substances, and
- Controlling temperature and humidity levels within the mine.
Yet, as mines expand and age, ventilation becomes more challenging. With deeper tunnels and complex layouts, airflow must be precisely managed and adapted to changes in mining activity and fluctuating gas levels.
To meet these demands, mines rely on large, surface-based fans that continuously push fresh air into various sections. This nonstop operation consumes a significant amount of energy, making ventilation one of the most energy-intensive aspects of mining.
Ventilation on Demand (VOD) has emerged to address these challenges, enabling smarter, more energy-efficient airflow management.
In today’s article, we dive into how VOD works, its benefits for mining operations, and how Minetek Air can support a seamless transition to this innovative system.
What is Ventilation on Demand (VOD)?
Ventilation on Demand (VOD) is a transformative solution for mining ventilation, delivering fresh air to specific areas of a mine only when and where it’s needed. This shift from a static to a dynamic, intelligent air supply makes ventilation more efficient, significantly reducing the total airflow required across the mine.
Traditionally, mine ventilation operated on fixed schedules, often leading to over-ventilation during low-activity periods, wasting energy and reducing air quality. VOD changes this by using real-time data and advanced algorithms to continuously monitor variables like airflow velocity and temperature. This technology enables precise ventilation adjustments, allowing operators to meet each area’s requirements as conditions change.
Benefits of VOD for Mining Operations
Resource Efficiency
VOD’s intelligent air system activates ventilation only where and when it’s needed, avoiding the unnecessary operation of the entire system. This selective approach conserves energy and reduces equipment wear, extending the life of ventilation infrastructure and lowering maintenance costs.
Energy Savings
By reducing the volume of air pumped through the mine, VOD lowers electricity use, one of the largest costs in mining. Optimising airflow cuts energy expenses, leading to substantial financial savings and helping mines meet sustainability goals by reducing their carbon footprint.
Improved Air Quality
Through real-time monitoring and advanced algorithms, VOD delivers precise ventilation, preventing both under-ventilation, which can lead to unsafe conditions, and over-ventilation, which can disrupt the underground atmosphere. This precise control enhances air quality, supporting better health and safety for miners.
Safety and Comfort
VOD enhances the mining work environment by maintaining essential oxygen levels and reducing harmful contaminants. This positively impacts miners’ well-being, helping reduce health-related absences and boosting productivity. Comfortable conditions are vital in high-stress environments like mines, where physical and mental strain can be significant.
Cost Effectiveness
VOD increases ventilation system efficiency, minimising operational costs tied to energy consumption and maintenance. Reduced airflow needs often allow for smaller, more affordable ventilation equipment, cutting both initial setup costs and ongoing expenses.
Ultimately, VOD represents the future of mining ventilation, where technology and necessity come together to create safer, more efficient mining practices.
