Underground mine cooling systems
Effective cooling and ventilation for the below ground operations
With increasingly remote locations being mined and temperatures regularly exceeding 45 degrees Celsius, it’s more important than ever that your below ground operations are effectively cooled and ventilated.
Not doing so doesn’t just pose a serious health risk to your employees but also leaves your equipment vulnerable to malfunction.
Underground mine ventilation systems matched to your unique needs.
The inflexibility of traditional built-in cooling and mine ventilation systems often means they’re unsuitable for varying demands, that’s why we offer an alternative approach.
Aggreko’s short and long term cooling solutions will help overcome the most common concerns that many mine safety engineers have:
1. Mine Safety: Keeping Everyone Cool
The ‘safe zone’ for working temperatures is below 30 degrees Celsius, and you need to trust your plant will achieve this all day, every day. With Aggreko not only can you easily scale your cooling and ventilation plant to match your demand, you also benefit from our expertise to ensure your needs are always met.
2. Affordable Mine Cooling
There are significant cost-savings to be had with a flexible partner like Aggreko, freeing up capital that can be invested elsewhere in your operation.
3. Mining Cooling Systems Maintenance
With Aggreko, you’re not liable for expenses around maintenance or upgrades. As well as reducing overheads, our team will ensure any maintenance is completed quickly to eliminate downtime.
4. Scalable Cooling Solutions for Mining
As mine operations are closely linked to market changes, the ability to scale up and down easily and efficiently is key. This isn’t possible with a built-in cooling and underground mine ventilation plant, but with Aggreko, you can quickly modify your setup at a fraction of the cost of buying a new permanent plant.
What is required for effective underground mine cooling and ventilation?
Generally, this refers to eliminating the risks of heat related injuries such as heatstroke and heat exhaustion, and the use of underground mine ventilation to remove toxic gases which can build up due to mining activity.
To do this effectively, the following mining ventilation equipment is usually required:
Cooling towers for mines
Evaporative cooling towers work by dissipating excess heat via water evaporation. Among the roles our rental towers can fulfill are:
- Supplementing cooling water flows.
- Providing additional cooling for planned system upgrades.
- Helping mines recover from in-built cooling tower failures in emergency situations.
Our rentals can be combined to provide multi-megawatts of cooling to your mine.
Chillers for mines
When you have high volume mines in hot countries, it’s common that you’ll need additional or emergency cooling plants on top of your air conditioning units.
Here you have a choice between water-cooled and air-cooled chillers. While water-cooled options are usually more energy efficient and take up less space, air-cooled are generally quicker to mobilise.
Our experts can help you select which would be better suited to your operation in terms of type and size.
Air conditioners for mines
Heat and humidity are among the most serious health risks facing mining staff and can also cause damage to your operations equipment. As such, standalone air conditioning units are essential for safety and productivity.
Our portable air conditioners are perfectly suited for maintaining safe temperatures in a wide range of different settings.
As well as reducing air temperatures, our packaged air conditioning unit removes moisture, making underground working environments far more comfortable for staff on long shifts. All of our mine air conditioners can be provided with a complete range of ancillary equipment.
Heat exchangers for mines
Instead of cooling or heating a process or fluid through direct contact, sometimes the best method is to use a heat exchanger. A heat exchanger keeps fluids separate while allowing constant energy transfer to take place.
Our skid-mounted rentals are perfect for removing bottlenecks and deploying when built-in alternatives fail. In addition, heat exchangers can be combined with chillers to cool a wide range of process fluids.
General mine ventilation
Underground mine ventilation is particularly important in situations where heavy machinery is in operation, as plants such as drills and long-haul dumps have a huge impact on humidity and temperature. On top of this, extraction can release gases which are harmful to staff working below ground. For example, radon, which is often present in uranium mines, is poisonous if inhaled.
We can help you find the right mine ventilation system that will keep your staff safe, and your equipment in optimal working condition.
Aggreko can also assist with all of your energy storage and power generation requirements so that you will always have a reliable source of power for all your operations. We use the latest technologies that will ensure your site is powered no matter how remote your operations are. This includes reliable power for construction, camps, communications, crushing, ventilation and underground air conditioning so you are providing a safe and compliant work environment for all of your workers in any situation.
