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

Publish date: 17 فبراير 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.

How Minetek’s Water Solutions Help Combat the Challenges of Acid Mine Drainage

Publish date: 12 نوفمبر 2024

In metal mines, valuable ores like gold, silver, and copper are often found within sulphide minerals. When these sulphides are exposed to air and water during mining operations, a chemical reaction generates sulfuric acid. This acid can then dissolve and release toxic metals and metalloids, such as arsenic, from the surrounding rock, leading to a dangerous environmental issue known as acid mine drainage (AMD).

Understanding Acid Mine Drainage

Acid mine drainage (AMD) can occur wherever sulphide minerals are exposed, including waste rock piles, tailings (the residue from ore processing), open pits, underground tunnels, and leach pads. A common sign of acid drainage is “yellow boy,” a yellow-orange precipitate that forms when the pH of acidic water rises above 3, causing dissolved iron to solidify and settle. Streams affected by AMD often have dangerously low pH levels—sometimes as low as 4 or lower—making them as acidic as battery acid. These highly acidic conditions severely damage aquatic life, plants, and wildlife dependent on these ecosystems.

A notable example is the Zortman Landusky mine in Montana, where acid and metal runoff has devastated biological life in numerous streams across the Little Rocky Mountains. The long-lasting nature of acid mine drainage makes it particularly destructive—it can continue to occur long after mining activities have ceased. A comprehensive literature review on the subject has noted that no hard rock surface mines have been able to demonstrate the successful cessation of acid mine drainage once it has begun on a large scale. This enduring environmental threat underscores the necessity of stringent laws and regulations to manage and mitigate the impacts of mining operations.

To address this ongoing threat, it is essential that mining operations are held to the highest environmental standards. Preventing AMD requires thorough planning and management of waste rock, tailings, and other mine by-products, along with effective water treatment systems to neutralise acid before it causes lasting damage.

The Importance of Progressive Rehabilitation in Australian Mining

Publish date: 12 نوفمبر 2024

The Importance of Progressive Rehabilitation in Australian Mining

In recent years, the Australian mining industry has made notable progress in meeting social and environmental responsibilities, particularly through the growing emphasis on progressive rehabilitation plans at active mine sites. This shift reflects a positive change, integrating environmental restoration as a continuous part of mining operations rather than a final step.

These sustainable practices represent a sharp contrast to historical mining approaches, which often left behind a legacy of abandoned, environmentally compromised sites. Australia now hosts approximately 80,000 inactive mines, many dating back to the gold rush era of the 1850s—a period of rapid economic growth that helped build cities like Melbourne but left a lasting environmental impact.

Without regulations for mine rehabilitation at the time, many sites were deserted after resource extraction, resulting in persistent environmental issues today. These abandoned mines contribute to dust pollution, soil erosion, and waterway contamination from heavy metals and other pollutants, underscoring the critical importance of current sustainable practices in the industry.

The enduring impact of abandoned mines underscores the critical need for ongoing rehabilitation. In regions impacted by historical mining, state governments continue to address the environmental legacies left behind, undertaking complex and costly remediation projects. These efforts often involve removing toxic materials, stabilising mine tailings, and restoring natural habitats.

Proactive rehabilitation is essential—not only for addressing immediate environmental risks but also for supporting the long-term ecological health of areas surrounding mining sites. The industry’s commitment to reducing its environmental footprint is evident in the mandate for progressive rehabilitation practices at all active mine sites, ensuring responsible land use and sustainability.

Water Management Challenges in Mine Closure

Water-related issues are among the most severe environmental impacts following mine closures, with effects that can persist for decades or even centuries. When mines cease operations, a lack of ongoing management can lead to the build-up and release of contaminated water, posing significant risks to nearby ecosystems and communities. A major concern is acid mine drainage (AMD), a reaction where sulphide minerals in exposed rock surfaces interact with air and water to produce sulphuric acid. This acid then leaches heavy metals from the surrounding rock, creating a toxic mix that can pollute nearby rivers, lakes, and groundwater.

An example highlighting these issues is a 2017 study by Dr. Ian Wright, a prominent Australian water scientist. His research on the Berrima Colliery, an abandoned coal mine in New South Wales under ‘care and maintenance’ since 2013, revealed that the site was releasing roughly 30 litres of heavy metal-laden water per second into the Wingecarribee River—equivalent to an Olympic-sized pool of toxic water discharged each day. This study underscores the ongoing challenges posed by water contamination at closed mine sites.

The water discharged from the Berrima Colliery contains dangerously high concentrations of heavy metals, including zinc, nickel, and manganese—elements known to harm human health and aquatic ecosystems. For example, zinc levels are more than 120 times the normal baseline, posing a serious threat to the river’s ecological balance. These contaminants degrade water quality and accumulate in the river’s sediment and organisms, leading to lasting ecological damage.

The impact of this contamination goes well beyond the immediate environment. As part of Sydney’s drinking water catchment, the Wingecarribee River could affect the health of millions relying on it as a water source. Local fishing communities are also concerned, as heavy metals bioaccumulate in the food chain, affecting fish populations essential for nutrition and livelihood. Contaminated fish present direct health risks to consumers who may unknowingly ingest toxic substances.

This case highlights the potential long-term impact of mining on water resources, underscoring the need for robust water management and treatment in mine closure plans. Without such measures, abandoned mines could continue to threaten public health, ecosystems, and local economies for generations.

The Transformative Power of VOD in Underground Ventilation

Publish date: 12 نوفمبر 2024

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.
