Publish date: 17 April 2025

Driving down costs & impact with efficient underground ventilation

The mining industry is evolving rapidly, and forward-thinking operators are already capitalising on energy-efficient innovation.

Underground ventilation alone can account for 42 – 49% of a mine’s total energy spend. With rising energy prices, growing ESG (Environmental, Social, and Governance) pressures, and the global demand for more sustainable operations, mining leaders are being pushed to challenge the status quo.

Minetek Air is meeting this challenge head-on. Our underground ventilation solutions, incorporating technologies like Ventilation on Demand (VoD), high-output axial fans, and Performance on Demand (POD) are engineered to reduce energy consumption, cut operational costs, and align with evolving ESG expectations.

This article explores how our systems are transforming ventilation from a cost centre into a competitive advantage for modern mining operations.

The evolution of underground ventilation

Underground mining has always been a battle against the elements. From confined working conditions to toxic gases and extreme heat. Effective ventilation is critical to safety and productivity, clearing hazards such as methane, diesel particulates, and dust.

In the early days, systems were rudimentary, relying on natural airflow or simple fans. As mines grew deeper and regulations tightened, ventilation systems became more sophisticated. By the mid-20th century, electric fans were standard, but many were inefficient, oversized, and operated continuously, significantly inflating energy usage.

The turning point: Sustainability and efficiency take the lead

As energy costs surged in the 21st century, the mining industry faced a critical turning point. At the same time, ESG pressures mounted—PwC’s 2023 Mine Report revealed 35% of mining CEOs now rank climate risks among their top concerns. This convergence of environmental and economic demands ignited a wave of innovation. Minetek Air responded with underground ventilation solutions that go beyond simply moving air—they optimise it. Today, technologies like VoD and high-output axial fans are reshaping industry standards, proving that performance and sustainability can thrive together underground.

This convergence of environmental and economic pressure sparked a new wave of innovation. Minetek Air responded by engineering smart ventilation solutions designed not just to move air, but to optimise it.

Technologies like VoD and high-output axial fans are now transforming how ventilation is managed, proving that performance and sustainability can thrive together underground.

Minetek Air’s four pillars of impact

1. Energy-efficient mining solutions: Cutting costs at the core

Mining energy consumption is a beast, but Minetek tames it with precision. Traditional ventilation systems run at full tilt 24/7, wasting power in areas where no one’s working. Minetek energy-efficient mining solutions flip that script. Our high output axial fans, paired with the Mine Air Control (MAC) system, deliver airflow only when and where it’s needed, slashing power usage by up to 50%. A 2024 Straits Research report projects the mine ventilation market to hit $1.86 billion by 2032, driven by demand for such technologies. For a typical underground mine, where ventilation eats up nearly half the energy budget, this translates to millions in savings annually – money that can be reinvested into operations or ESG initiatives. It’s not just cost-cutting; it’s strategic resource management.

2. Ventilation on Demand (VoD): Smart airflow, smarter savings

Ventilation on Demand (VoD) is the brain behind Minetek Air’s brawn. Integrated with mine communication systems, VoD uses RFID trackers to monitor worker and vehicle locations, adjusting airflow in real time. No more blasting air into idle tunnels – Minetek’s systems sync with schedules and activity, reducing energy waste. The Canadian Mining Journal reported in 2023 that VoD can cut energy intensity by 20-50%, with payback periods as short as two years. At a Gold Mine in Western Australia, Minetek’s VoD-enabled primary fans (1,100kW, 280-350 m³/sec) met production needs while slashing power costs. This isn’t just about efficiency; it’s about giving mine managers control to optimise underground mine ventilation without compromising safety or output.

3. High Output Axial Fans and POD technology: Power meets precision

Minetek’s high output axial fans are engineering marvels – compact, yet packing double the pressure of standard fans, with a steel impeller built for harsh conditions. Coupled with Performance on Demand (POD) technology, these underground ventilation fans adapt airflow without pricey variable speed drives (VSDs). Need to clear blast gases fast? Surge past the duty point. Idle time? Dial it down. A 2024 Minetek case study showed these fans cut re-entry times at development ends, boosting productivity while trimming energy use. Unlike traditional setups requiring multiple units, Minetek’s design – 40% shorter, 10% lighter – reduces capital costs and installation headaches. It’s a one-two punch: high performance, low footprint.

4. Mining ESG solutions: Sustainability without sacrifice

ESG isn’t a buzzword – it’s a mandate. Minetek’s mining ESG solutions align with this shift, reducing environmental impacts while keeping operations profitable. Ventilation accounts for a hefty chunk of a mine’s carbon footprint, but Minetek’s systems shrink it. By halving fan numbers and power draw, they lower emissions – critical as 70% of U.S. metal mines adopted advanced ventilation controls in 2024, per the Mine Safety and Health Administration. Public opinion on LinkedIn echoes this: a 2023 poll by Mining Technology showed 82% of industry pros prioritise sustainability in vendor choices. Minetek delivers, helping mines like Agnew Gold hit net-zero targets without gutting budgets. It’s proof that reducing mining energy costs and environmental harm can go hand in hand.

A smarter, leaner future for mining

Minetek’s underground ventilation technologies represent more than innovation, they’re a new standard for efficient, ESG-aligned mining. With VoD, POD, and high-output axial fans, operations can slash energy costs by up to 50%, enhance safety, and meet the demands of a sustainable future.

Now is the time to rethink ventilation, not just as a necessity, but as a strategic advantage.

Water | Freshet surge: The critical risks mining can’t ignore

Publish date: 31 March 2025

The growing challenge of climate change in mining

The mining industry is no stranger to extreme environmental conditions. However, rising global temperatures are intensifying the challenges posed by seasonal changes.

Freshets, which occur during spring thaws, lead to rapid snow and ice melts that significantly increase groundwater levels. These events, when combined with heavy rainfall or excessive snowfall, create severe risks for mine sites. Infrastructure, roads, Tailings Storage Facilities (TSF), and waste dumps are particularly vulnerable, with failures potentially leading to environmental disasters and operational shutdowns.

Understanding the risks: freshet snowmelts and their impact

Mines located in northern climates, such as Canada and the United States, must be prepared for the unique challenges posed by heavy snowfall and freshet conditions. As snow and ice accumulated within the tailings footprint begin to melt, the resulting water must either be contained within the TSF or discharged appropriately. During these high-intensity periods, water inflows can surpass a mine’s discharge capacity, leading to rising water levels in TSFs.

When tailings and water storage facilities reach their maximum allowable water levels, the risk of dam failure becomes a serious threat. Without proper water management strategies in place, mines may be forced to halt production, leading to costly operational disruptions and potential environmental consequences. If water levels exceed capacity, toxic acid water can be released into the surrounding environment, causing long-term ecological damage.

Real-world examples of freshet impacts

Several mining operations have experienced devastating impacts due to freshets:

Sibanye-Stillwater’s Uranium and Gold Mines in Montana faced a catastrophic flood event in 2022, triggered by rapid snow and ice melts. The situation was worsened by excessive rainfall, leading to widespread damage and months of lost revenue.

Minto Gold Mine in Yukon, Canada, suffered a severe freshet event in Q2 of 2022, with snowfall levels 150%-400% higher than normal. Operations were suspended for over four weeks, costing millions. The mine recorded a $9.5 million CAD loss over three months due to the unexpected water inflow.

These cases highlight the urgent need for mining operations to establish effective water management strategies to mitigate freshet-related risks.

Proactive water management: How mines can prepare

Mining operations across Canada and the U.S. must prioritise emergency response planning for freshet seasons. Key strategies include:

Implementing a Comprehensive Water Management Plan – Mines must have a proactive approach to managing excess water during freshet periods. This includes monitoring environmental conditions and having emergency response procedures in place.
Regularly Assessing TSF and Water Storage Capacities – Ensuring that tailings dams and water storage facilities can handle seasonal water inflows is crucial to avoiding failures.
Deploying Advanced Water Evaporation Systems – One of the most effective ways to manage excess water is through mechanical water evaporation systems that safely and efficiently remove surplus water.

Air | Engineering the future of mine ventilation

Publish date: 27 March 2025

In the early days of mining, operations were relatively simple, and ventilation systems were primarily designed to deliver large volumes of air to underground workers. Ventilation shafts and fans were standard, operating in a straightforward manner to provide fresh air while removing hazardous gases. However, these early systems lacked flexibility—they couldn’t easily adapt to changes in mine layouts or activities, leading to inefficiencies.

As mining technology progressed, so did the complexity of operations. Mines became deeper and more intricate, with multiple levels and extensive tunnel networks. This increased depth introduced new challenges, including rising temperatures, higher concentrations of hazardous gases, and the need for more advanced ventilation to reach remote and complex areas of the mine. What was once a simple task of pushing air underground evolved into a highly demanding operation, requiring strategic planning and real-time airflow adjustments to ensure both safety and efficiency.

With these growing demands, ventilation systems had to evolve. Mines required not only greater air supply but also systems capable of actively controlling where and when air was delivered. Modern ventilation solutions needed to respond dynamically to shifts in mining activity, adapt to temperature fluctuations, and effectively manage emissions from machinery and blasting operations.

The shift toward real-time ventilation control

This transition toward more sophisticated ventilation systems wasn’t just a technological advancement—it became a necessity for ensuring the safety of underground workers. The ability to rapidly respond to changing conditions, such as sudden spikes in harmful gases or drops in oxygen levels, provides a level of security that earlier systems simply could not offer. This reflects the industry’s unwavering commitment to worker safety.

However, progress has come with its own set of challenges. Today’s mines must carefully balance providing adequate airflow to maintain worker safety while managing energy consumption. Modern mining environments are vast, featuring both active and inactive zones, each requiring different levels of ventilation at different times. Beyond supplying fresh air, ventilation systems must also manage exhaust gases from diesel-powered machinery, control heat generated by both equipment and surrounding rock, and minimise dust distribution.

This balancing act is further complicated by ventilation being one of the most energy-intensive aspects of mining operations. In deep mining, ventilation can account for an astonishing 42% to 49% of total energy consumption. With rising energy costs, mining companies face mounting pressure to reduce their energy footprint without compromising safety.

Stricter regulations and the push for sustainability

Mining companies are also subject to increasingly stringent regulations, with governments and industry bodies enforcing stricter occupational exposure limits for gases, dust, and noise. Allowable concentrations of hazardous gases have been significantly reduced, while noise levels must remain below designated thresholds to protect workers’ hearing. While worker health and safety have always been a top priority, today’s regulations demand even greater precision in monitoring and controlling underground conditions. As a result, ventilation systems must be not only powerful but also highly adaptable and precise.

Simultaneously, the mining industry faces growing public and investor scrutiny, driving the adoption of more sustainable and environmentally friendly practices. Rather than resisting this shift, the industry has embraced innovation. Mining operations are expected to cut carbon emissions, lower energy consumption, and operate with a reduced environmental footprint. This demand has fueled significant advancements in ventilation technology, leading to the development of more energy-efficient and intelligent solutions. The industry’s proactive approach to sustainability is a positive indicator of the future of mining.

One of the most promising innovations in this space is Ventilation on Demand (VOD). This advanced system is revolutionising airflow management in underground mines. Unlike traditional ventilation setups that deliver a constant airflow across the entire mine, VOD leverages sensors to detect where and when fresh air is needed, adjusting airflow accordingly. This optimised approach not only enhances energy efficiency but also provides a safer and more comfortable working environment for miners.

How Minetek Air is redefining industry standards

A prime example of VOD in action is Minetek’s Mine Air Control (MAC) technology. MAC utilises advanced sensors and RFID tracking to monitor the movement of personnel and machinery throughout a mine. Based on this real-time data, the system automatically adjusts ventilation to ensure fresh air is directed exactly where it’s needed, eliminating the need for manual intervention. This intelligent airflow management not only ensures optimal ventilation in critical areas but also enhances productivity by allowing miners to focus on essential tasks.

By continuously responding to underground conditions, MAC and similar systems enable a more adaptive and efficient approach to mine ventilation. For instance, if a particular zone is unoccupied or inactive, the system can reduce airflow to that area, conserving energy and extending the lifespan of ventilation equipment. This on-demand approach significantly reduces operational costs while improving overall worker safety.

One of Minetek’s most groundbreaking innovations is its Performance on Demand (POD) technology. Traditionally, mine ventilation systems relied on Variable Speed Drives (VSDs) to adjust fan speeds, offering some level of flexibility but also presenting limitations. Minetek’s POD technology eliminates the need for VSD controls altogether, enabling direct airflow adjustments without relying on intermediary speed controls.

This next-generation approach ensures that airflow is precisely regulated—delivering exactly what is required, no more and no less—resulting in an ultra-efficient system. The precision of POD technology allows mines to maintain safe and effective ventilation while significantly reducing energy consumption. In fact, this method can achieve energy savings of up to 50%, offering substantial cost reductions while supporting environmental sustainability goals. By aligning with the broader movement toward greener mining practices, POD technology underscores the economic viability of sustainability in the industry.

With advancements like MAC and POD, Minetek Air is setting a new benchmark for efficiency, safety, and sustainability in underground ventilation. These technologies not only address the industry’s most pressing challenges but also pave the way for a more innovative, cost-effective, and environmentally responsible future in mining.

Flooded mines, lost millions: why heavy rainfall could shut down your mine

Publish date: 18 February 2025

Heavy rainfall events are becoming more frequent and intense globally. Dr. Andrew Dowdy, an associate professor at the University of Melbourne and an expert on extreme rainfall trends, highlights, “Many lines of scientific evidence show that sub-daily rainfall extremes have already increased in intensity compared to previous decades due to the human-caused global warming that has already occurred.” This surge in extreme weather is not isolated to specific regions; Europe, North America, and many other parts of the world have experienced historic rainfall events, leading to widespread flooding and destruction.

The Impact of Heavy Rainfall on Mining Operations

Mining operations are particularly vulnerable to the challenges posed by heavy rainfall. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) warns, “As climate changes, extreme weather events are growing in frequency and will inevitably lead to productivity, safety, and environmental challenges for mines.”

Open-Pit Mines: Excessive rainfall can cause water accumulation, requiring costly drainage systems and operational downtime while water is pumped out.

Underground Mines: Flooding risks are amplified, as water infiltration can compromise tunnel integrity, posing severe safety hazards to workers.

The degree of impact varies based on mine type, size, and location. Tropical regions face increased downtime due to persistent rainfall, while previously arid areas struggle to adapt to sudden weather extremes. Flooding often leads to operational halts, project delays, and significant financial losses, alongside heightened safety risks such as infrastructure destabilisation, landslides, and hazardous working conditions.

The Consequences of Inadequate Water Management

A striking example of the consequences of poor water management occurred in March of last year when a Copper Mine in Queensland faced severe flooding. Water levels reached seven metres, causing significant damage to supporting infrastructure and prolonged operational downtime, resulting in lost revenue and increased repair costs.

One of the most critical challenges is the impact on Tailings Storage Facilities (TSF). Excessive rainfall can destabilise these structures, increasing the risk of catastrophic dam breaches, releasing hazardous materials into the environment.

Case Study: Brumadinho Dam Disaster (Brazil): The collapse of the tailings dam at the Córrego do Feijão iron ore mine tragically claimed 272 lives, highlighting the devastating human and environmental toll such failures can have.

2024 has come to an end and it’s time to look ahead. The mining and industrial sectors continue to face a dynamic environment marked by evolving challenges and demands—a pattern that will persist into 2025. However, these shifts also create opportunities for companies ready to innovate, adapt, and lead.

Building Resilience Through Purpose

Integrating purpose into the core of mining operations is vital for fostering resilience and responsibility. Over the past decade, the industry has advanced significantly in environmental stewardship and community engagement. Both crucial for regulatory compliance and maintaining a social licence to operate. This commitment to purpose-driven practices will continue to deepen as sustainability becomes a central focus.

In early 2024, leading mining corporations pledged to support a nature-positive future by 2030. This initiative focuses on enhancing biodiversity, protecting ecosystems, and restoring habitats, reflecting the industry’s growing awareness of its environmental footprint. A report from Accenture shows that seven of the top ten mining companies are targeting net-zero emissions by 2050, addressing both direct operations and purchased energy. For 2025, expect increased investments in renewable energy sources such as solar, wind, and hydropower, alongside innovative carbon reduction strategies – initiatives that support global climate goals and long-term operational sustainability.

Adapting to Regulatory Changes

The regulatory landscape is rapidly evolving. Governments worldwide are introducing stricter environmental and sustainability standards, requiring mining companies to adapt. Beyond emissions targets, new regulations will demand comprehensive biodiversity assessments, habitat restoration plans, and strategies to enhance ecosystem resilience. Mining companies must proactively integrate these requirements into their operations to stay compliant and competitive.

Water management is also under increased scrutiny. As water scarcity becomes a pressing global issue, tighter regulations on water usage, monitoring, and wastewater discharge are expected. Mining operations must adopt sustainable water management practices, including technologies that reduce consumption and improve efficiency. By staying ahead of these regulatory developments, companies can mitigate risks and capitalise on emerging opportunities, ensuring long-term success.

Embracing Technological Innovation

Technological advancements are reshaping the mining industry. Over the past few decades, digital transformation has introduced data analytics, drone technology, and autonomous equipment, revolutionising operations, safety, and sustainability.

Automation is a standout innovation. Autonomous trucks, drills, and loaders enhance efficiency, reduce human exposure to hazardous conditions, and optimise production cycles. Further investments in R&D will drive the development of advanced technologies tailored to mining. Companies embracing these innovations will not only boost operational efficiency but also achieve sustainability goals through reduced waste, improved energy management, and optimised resource utilisation.

Breathing in danger: How poor underground air quality is suffocating your site operations

Publish date: 17 February 2025

Underground mining is essential for resource extraction, but it comes with unique challenges—air quality being one of the most critical. The confined nature of underground spaces, combined with restricted natural airflow, makes them prone to the buildup of toxic gases such as methane and carbon monoxide. Diesel exhaust from machinery only worsens these risks. Without effective ventilation, these hazards can accumulate quickly, transforming a mine into a dangerous, even life-threatening, environment.

The Hidden Dangers of Poor Air Quality

One of the most severe threats in underground mining is the accumulation of flammable gases like methane. At high concentrations, methane can ignite, causing catastrophic explosions. Equally hazardous is carbon monoxide—an invisible, odourless gas that silently endangers lives. Even small doses can hinder oxygen delivery in the bloodstream, leading to poisoning and potentially fatal consequences.

Inhalation of fine dust particles, particularly in coal mining, can also lead to pneumoconiosis (black lung disease), causing long-term respiratory damage and irreversible lung conditions. This underscores the critical need for advanced ventilation systems to protect workers’ health.

The Crucial Role of Ventilation in Temperature Control

Air quality management extends beyond gas and dust—it’s also about temperature regulation. Depending on a mine’s depth and location, underground conditions can swing from dangerously hot to freezing cold. In deep mines, geothermal heat can cause extreme temperatures, raising the risk of heat exhaustion or heatstroke. Conversely, in colder regions, poor ventilation can result in hypothermia. Effective ventilation systems help regulate temperatures, creating safer, more productive work environments.

Meeting Legal and Regulatory Standards

Proper ventilation isn’t just best practice—it’s a legal requirement in many mining jurisdictions. For example, regulations in Western Australia mandate detailed ventilation plans tailored to each mine’s unique conditions. These plans factor in mine depth, mineral type, and equipment used, all to disperse harmful gases, control temperatures, and maintain airflow that protects worker health and safety.

Minetek: Pioneering the Future of Mining Ventilation

For nearly four decades, Minetek has been a global leader in developing innovative, efficient, and cost-effective ventilation systems for underground mining. Our commitment to advancing technology and delivering customised solutions has helped mining companies worldwide optimise ventilation strategies, meet regulatory standards, and prioritise worker safety.

Revolutionising Airflow with Performance On Demand (POD) Technology

One of Minetek’s most revolutionary innovations is our Performance On Demand (POD) technology. Unlike traditional systems that rely on Variable Speed Drive (VSD) controls requiring constant monitoring and manual adjustments, our POD system uses single-speed fans that automatically regulate airflow based on real-time conditions. These intelligent fans adjust dynamically to provide the exact amount of air needed, enhancing safety through consistent circulation and effective dispersion of toxic gases and heat.

Maximising Energy Efficiency and Reducing Costs

Minetek’s ventilation solutions are designed with energy efficiency at their core. By eliminating the need for continuous high-speed fan operation, our systems can cut energy consumption by up to 50%. This not only reduces operational costs but also supports sustainability goals, delivering a strong return on investment while advancing environmental, social, and governance (ESG) objectives.

Engineered for the Toughest Conditions

Our ventilation fans are built to endure the harshest underground environments. With steel-fabricated impellers, they achieve pressure levels once thought impossible for underground operations. This rugged construction ensures exceptional durability, reduces maintenance needs, and minimises operational downtime—crucial for maintaining productivity in demanding mining conditions.
