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

Publish date: 17 Februari 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.

A key development is the creation of an interagency working group by the Department of the Interior. This group is focused on overhauling hardrock mining laws, regulations, and permitting policies to support President Biden’s goals for better environmental protection, sustainable resource management, and responsible mining practices.

Made up of experts in mine permitting and environmental law, this group will review current laws and processes to suggest improvements that prioritise environmental, community, and Tribal engagement standards at every stage of mine development.

The newly released Fundamental Principles for Domestic Mining Reform by the Biden-Harris Administration is central to this effort. These principles prioritise environmental protection, community involvement, and fiscal responsibility, aiming to strike a balance between economic growth and environmental conservation.

These initiatives represent a watershed moment for the U.S. mining industry, which is confronting the need for modernisation and adaptation.

In today’s article, we will discuss the emerging trends in the mining industry and examine their implications for companies operating in America.

The impact of regulatory changes on the U.S. mining industry

We are seeing a significant shift towards sustainability worldwide, with more than 140 countries setting net-zero targets and covering about 88% of global emissions. Among them, the United States, historically one of the largest contributors to global emissions, is taking bold strides towards sustainability.

In line with the “Investing in America” agenda, the U.S. Department of Energy (DOE) has allocated up to $475 million to fund five projects across Arizona, Kentucky, Nevada, Pennsylvania, and West Virginia. These projects, situated on both current and former mine lands, represent a radical effort to accelerate the deployment of clean energy technologies in regions historically reliant on fossil fuel extraction. This substantial funding injection underscores the federal government’s commitment to promoting clean energy innovation and revitalising communities grappling with the decline of traditional mining industries.

The United States is taking a leading role in the clean energy revolution, striving for a future that’s more sustainable and resilient for generations to come. Yet, amidst these proactive steps, American mining operations are facing a changing regulatory environment, both locally and globally. As governments worldwide step up efforts to address climate change and promote environmental sustainability, mining companies are grappling with a complex array of regulations aimed at minimising their environmental footprint.

Within the U.S., initiatives like the Clean Air Act, Clean Water Act, and National Environmental Policy Act enforce strict environmental standards on mining activities. These standards require companies to implement pollution control measures, conduct thorough environmental assessments, and engage in transparent consultation processes with stakeholders. There is growing support for updating the 1872 Mining Law to promote clean energy initiatives.

In light of these trends, American mining firms are urged to embrace sustainable practices and embrace clean technologies. Moving ahead, it’s crucial to uphold regulatory compliance while fostering responsible resource management. By addressing environmental issues and embracing sustainability, mining companies can manage regulatory risks and foster long-term value in an increasingly environmentally conscious world.

Innovations in ventilation systems

Ventilation systems are critical to maintaining safe working conditions for miners, providing fresh cool air to underground miners, and diluting flammable and machine exhaust gas. Yet their energy consumption accounts for a significant portion—often 40% or more—of a mine’s total energy usage. This places a substantial financial burden on mining operations and underscores the imperative to minimise energy consumption while maximising efficiency.

To tackle this challenge, mines are increasingly focusing on adopting energy-efficient ventilation techniques. This means embracing advanced technologies like automated airflow controls, and optimised ventilation designs. The aim is to reduce energy consumption while ensuring safety and maintaining air quality standards.

3 key trends driving underground ventilation

Publish date: 21 Juni 2024

From the moment mankind began the pursuit of mining the earth for valuable commodities, there has been one unchanged constant. The need for a safe, reliable and efficient supply of air to those underground. This can be achieved through adequate underground ventilation & air solutions.

Since the beginning of civilisation, man has toiled to extract stone, ceramics and later precious minerals to subsist, to improve his way of life and in time, to prosper. Following the onset of the industrial age, this pursuit has expanded on a vast scale and the need to supply air sustainably and in volume to underground operations has grown.

Today, however, while the pace at which mining is undertaken throughout the world has increased, the imperatives are changing. While the core responsibility of global miners is to provide sustainable operations, the need to constantly adapt and generate new efficiencies is ever-present. On top of the need for quality air supply, the industrial narrative is expanding with miners now charged with the mandate of achieving increased safety, profitability and environmental outcomes.

As the pace and scale at which mining continues into the future, there are three key enablers that are guiding this new era of mining & underground ventilation;

Flexibility
Technology
Agility

1. Ventilation flexibility

The ability to adapt to change is vital in any industry and being able to tailor processes to meet operating conditions is key. In underground mining, the ability to target air supply in line with production requirements is one of the main challenges for operators. To meet this challenge, the concept of underground Ventilation On Demand (VOD) has been prevalent in recent years with systems designed to deliver airflow to workings based on scheduling and people movements.

However, the contemporary approach to delivering on-demand air supply in recent times has been to regulate airflow through complex and expensive infrastructure. The solution has been the application of Variable Speed Drives (VSD), Variable Frequency Drives (VFD) or Variable Voltage Variable Frequency Drives (VVCFD) – which control power to the underground ventilation system enabling airflow to be ramped up or down based on demand.

It is a given that high air velocities require high-pressure gradients and maintaining this pressure across a mining network comes at a high cost. In the post-2007 Global Financial Crisis (GFC) era and the subsequent mining downturn of 2013, the use of VSDs was seen as the logical way to tailor the supply of airflow based on demand, with the primary benefit being a reduction in power consumption costs. For an underground mine, has been estimated that ventilation systems can contribute to as much as 50% of power consumption needs. While there has been a heightened focus on driving down costs to enable economically sustainable operations, VSDs still present somewhat of a conundrum.

By nature, VSDs are a costly solution in themselves, with infrastructure and supporting control software ranging in the tens to hundreds of thousands of dollars. As expensive as they are, they are equally fragile, requiring dedicated, air-conditioned rooms and custom cabling for operation. While the benefits of Ventilation On Demand via the use of VSDs seem apparent, their use now almost seems illogical in the harshest of underground environments.

If only there was another way…

Enter Australian business Minetek, with a new approach to optimising airflow underground called Performance On Demand (POD). Minetek has developed an innovative approach to optimising air circuits enabling a shift away from requiring costly VSDs. This is certainly a watershed moment in underground ventilation. Able to be manually or autonomously controlled, the mechanically driven solution delivers the required flexibility for operators by tuning the dynamics of the airflow over the system’s innovative impellers.

By mechanically controlling the flow of air over the impellers – not the supply of power to the fan – power consumption is optimised and can be maintained at a significantly lower level. Minetek has been able to deliver up to a 50% reduction in power consumption costs, all while enabling operators to maintain flexibility in line with production and scheduling requirements. From a broader perspective, POD considers the new imperatives faced by miners – by actually driving down operational costs and in turn yielding improvements in environmental outcomes.

This new underground ventilation approach delivers true flexibility whilst improving profitability and the long-term viability of underground operations.

2. Underground ventilation technology

They say necessity is the mother of all invention and underground mining has a rich history of reflecting this expression. Driven by necessity, the mining sector has been constantly innovating to deliver safe, reliable and efficient operations underground.

Technology in mining has evolved with mankind. From the ancient use of tools to extract precious metals, to the use of black powder explosives to break apart large rocks in the late middle ages, mining has been a proving ground for new technologies for millennia.

Given the severity of underground conditions, the appetite for the development of enabling technology has maintained pace if not exceeded that of life above ground. Driven by the need to ensure safety, improve operational efficiencies and focus on reducing environmental impacts, mining has been an eager, albeit cautious adopter of new technologies.

Over the past two decades, in particular, the shape of technology in mining has moved towards new underground ventilation themes. Automation, optimisation, digitisation and even electrification are the new focus for underground miners, as organisations explore new and integrated ways to meet their safety, profitability and environmental objectives.

Underground ventilation is a tremendous lever in achieving progress against all three objectives and the application of new technologies can have a significant impact. Now, the key drivers in underground ventilation are very much about the interoperability of disparate systems within the operating layer and automating processes to maximise performance.

For years the requirement for ventilation has fundamentally been to meet a minimum volume and pressure requirement; however, the evolved mine now recognises the need to optimise assets and processes – like every other aspect of production – to extract maximum efficiency, drive down operating costs and increase profitability.

Minetek has at its core a focus on innovation and is relishing the opportunity to challenge the status quo in the design, implementation and operation of an underground ventilation system. Outside of MINETEK’s radical approach to the design of fan systems, the focus is squarely on integrating with mine systems to enable autonomous operation. Performance On-Demand is an excellent example of applied technology and Minetek are moving beyond the focus on reducing power consumption to explore truly responsive operation. While Radio Frequency Identification (RFID) technology has been around since the mid-1940s, its application in the industrial world is now connecting opportunities to improve processes in mining.

Minetek has developed an innovative new approach to optimising air circuits by integrating RFID technology to trigger its Performance On-Demand ventilation system and target air delivery based on vehicle movements. The approach is a game-changer in enabling operators to effectively reduce airflow to parts of the mine with no scheduled activity, maintaining airbag inflation levels at a minimum and reducing power consumption costs exponentially.

By automating triggered airflow and removing the need for human intervention, both safety and operating performance can be optimised. Connecting modern ventilation technologies to leverage data and driving predictive processes is the path forward to achieving true operational efficiency.

3. Ventilation agility

Agility is defined as being able to move quickly and easily. Being nimble, lithe and spry. In recent years the term agile has been adopted in the project management field, characterising the approach to dividing tasks into short phases with a frequent reassessment of plans and priorities.

Although coined within software development circles, where the pace of change is rapid, this definition of agility is certainly apt for the continuously changing environment in which underground mining occurs. By definition, a mine is constantly changing. It is required to undergo a systematic change in its shape and size as ore body is extracted from the earth.

While the initial design of an underground mine provides operators with a road map of how their infrastructure will evolve, it is an agile project management and the understanding of how to apply resources over time that is required to continually adapt and optimise.

Agility requires a combination of technology and flexibility.

At Minetek, we have recognised the need to be agile and have partnered with leading mines the world over to apply the latest thinking in mine ventilation, which is enabling miners to meet and exceed their objectives. For example, Minetek’s innovative fan technology is giving operators flexibility through Performance On Demand. POD enables operators to quickly ramp up or down air delivery by directing the flow of air through innovative control vane design.

This approach removes the need for VSD intervention which offers a distinct performance improvement. By removing the need for VSD, mines can use all available power without the risk of fan stalling or creating harmonic imbalance. This flexibility in control and application offers true agility, by lowering power consumption and costs and also allows faster re-entries following blasting activity.

To be agile requires a lean approach.

Minetek’s robust designed single-speed fans, with blades virtually impervious to wear, have been proven to reduce power consumption costs by up to 50%. Also, by stripping away bulk, the compact fan design is enabling miners to achieve agility by enabling them to be safely and efficiently deployed across the network with ease.

Compared to traditional larger fans, Minetek’s compact units have the capability to outperform larger alternatives and then be redeployed quickly and easily to other locations as the mine workings evolve. By virtue of their smaller size, Minetek fans can be easily installed in a range of orientations and tight underground locations. This agility and responsiveness enable operators to adapt to changing conditions while reducing the potential for manual handling safety impacts.

To be truly agile requires confidence.

Minetek has built deep domain experience in the design, manufacturing, testing and installation of the most advanced fan systems in the world and is backed by a large team of aeronautical, mechanical and electrical engineers. From initial decline modelling and consultancy through to post-implementation support, our team has the combined capability to help deliver an agile approach to your next ventilation project.
