Lighting in underground mines

lighting underground minesA characteristic of underground mining operations is that, as we move from the surface to the interior, the darkness becomes more complete, which is why lighting is a very important and fundamental factor.

Under these conditions, it may be interesting for mining companies to focus on a key aspect of the production equipment, lighting.

In underground mines, it is vital to have safe and efficient lighting. Airfal manufactures high optical performance luminaires adapted to underground mines. These Atex certified light fixtures meet the highest safety standards and are explosion proof.

Explosion hazard in underground mines involves the use of special lighting to avoid possible accidents. In coal mines, firedamp concentration can be high, resulting in explosive atmospheres, An explosion can be caused by mechanical or electrical sparks.

Inside the mine, where the atmosphere is potentially explosive,  electricity has to be used safely. To prevent or minimize the effects of explosions, besides mine ventilation, electrical equipment and lighting has to be specially designed for use in explosive atmospheres.

All electrical equipment and lighting used in the mine must be able to withstand an internal explosion, and prevent any risk of spreading an explosion, which is called explosion-proof.

Lighting standards help ensure the safety of lighting installations in mines. The lighting systems used inside a mine must comply with the ATEX directive, and avoid any risk of explosion or propagation. The ATEX normative (explosive atmosphere) is the result of two European Directives (1994/9/EC and ATEX 137) for equipment intended for use in ATEX zones and 100A ATEX 1999/92/EC or safety of workers).

With many years of experience in technical lighting, Airfal has created the Minex luminaire which has been designed  for use in hazardous areas. With low maintenance cost, easy installation, and maximum security, the luminaire Minex is compliant with Atex. It was created especially for lighting in underground mines. It can also be used in other industrial facilities, both indoors or  outdoors.

Led light fixtures for the mining industry

Effective mining companies must use the latest technologies, including a safe and effective lighting system. The main characteristics of a lighting system for mines are safety, durability, efficiency and long life. Such elements are essential to survive in the harsh environment of the modern mining industry.

LED lighting is extremely popular today in the industry and in particular in mining, because of the many technical advantages of this technology. Increased longevity, efficiency, energy savings, respect for the environment are some of the many benefits that can offer LED light fixtures for mines. Airfal offers a range of lLED light fixtures suitable for mining, light and strong, with an exceptional lighting performance. These luminaires are designed for extreme environments, and can withstand explosions.

Certification of ATEX lighting: interview with Carlos Jiménez

ATEX lighting is very complex and still unrecognized by many industry professionals around the world. In the previous articles, we have analyzed what ATEX lighting is and why it is necessary to distinguish it from flameproof lighting.

Airfal is the only Spanish company certified to manufacture this type of lighting and to understand why it is so complex to certify this type of product, we interviewed Carlos Jiménez, director of Airfal’s R + D + i.

Carlos explains the process that follows an ATEX luminaire from the “first draft”bto its introduction on the market.

ATEX and Explosion-proof luminaires: why they are different

In many cases the terms ATEX and Explosion-proof are confused and according to many, they have the same meaning,  but this is far from being true.  reality. In addition, this error can lead to dangerous situations, and manufacturers and installers have a great responsability, so it is necessary to make the relevant distinctions.

LED lighting fixtures for use in hazardous areas

US system compared to EU Atex ZonesAt the same time that Lima Climate Change Conference is about to start, manufacturers have become increasingly aware of the urgent need to implement more environmentally friendly solutions for the planet. Lighting represents almost 20% of global energy consumption and industrial locations that operate 7 days a week and 24 hours a day consume a great deal of energy to ensure their lighting. To cope with these challenges, LED technology is now gaining widespread use in industrial lighting, as it is especially suitable for use in hazardous locations.
A high risk or hazardous area is where a mixture of air and potentially explosive substances such as gases, vapours, mists or dusts, could spread. Typical examples of hazardous environments are refineries, drilling platforms, chemical and power-generation facilities, mines… In these locations, it is required to ensure safety against occurrence of arcs, sparks and excessive temperature. Currently, lighting for shale gas drilling platforms that are expanding in many countries, requires compliance with a gas facility classified as Zone 1 (ATEX hazardous area) and Zone 2 (standards Class I Div 1 and Class I Div 2 in the USA).
LEDs are full-spectrum light sources and provide excellent color rendering. LED directs the light to where it’s needed with very little scattering or loss. By contrast, conventional lamps cast light in every direction hence the reduction in lumens compared to LEDs. Not only LED lights meet the highest standards of color rendering IRC (70-85), efficiency (up to 160 lumens/watt) and lifetime, but in addition, unlike other sources such as fluorescent tubes, their emissivity is increased in cold environments.
Compared with sodium vapor lamps under high pressure to mercury vapor lamps or incandescent lamps, LED can prevent accidents related to poor visibility thanks to its better color rendering. LED lighting also facilitates better reading of safety instructions for earlier intervention in cases of immediate danger. This helps to lower the risks of accidents and allow faster interventions.
Intelligent lighting control can furthermore provide lighting as needed: LED lighting offers another advantage of being able to vary the light intensity as needed without loss. Coupled to sensors, LED lighting can adapt and increase or decrease the brightness depending on the presence of certain gases, some dust or in case of fire. In addition, a centralized management is now possible to optimize energy savings.
High ceilings in industrial facilities make that the light fixtures can be remote or difficult to access. Maintenance and replacement could be extremely expensive. Sturdy and long running, LED lighting requires very little maintenance, which is essential, due to the vast expense of a shutdown. Containing no gas, LED lights are very safe and recycling is easier, like any other electronic product. With 100,000 hours of life, LED lighting reduces the need for maintenance. Even coupled with an intelligent lighting system, it only lights up when needed and it turns off automatically.
In hazardous areas such as drilling platforms lighting also has to be able to withstand constant shock and vibration. ATEX certified lighting should be stronger than traditional lighting. With a 100% electronic lighting, LED is already more resistant than other materials.
Airfal develops ATEX certified LED lighting solutions (Pyros, Vitra and Secure) that reduce energy consumption without compromising the level of lighting, especially in hazardous locations. Resistant to shock and vibration, they avoid the frequent replacement of lamps. They don’t contain mercury or other hazardous products to make them more ecological. Airfal LED light fixtures are environmentally friendly and offer energy efficiency and light control for difficult and harsh locations.

How to manage lighting for hazardous areas ?

atmosfera explosible

A hazardous area is defined as any place in which an explosive atmosphere may occur. Hazardous areas may exist due to flammable gases or vapours or combustible dust. Explosions can cause loss of life and serious injuries as well as extensive damage. If there is enough quantity of flammable substance (the fuel) mixed with oxygen (the oxidizer), an ignition source (e.g. an electric spark) is sufficient to cause an explosion, in which combustion spreads to the entire mixture yet unburned, and can be caused by unadapted light fixtures.

Where can explosive atmospheres be found?

Many workplaces may develop or have activities that produce explosive or potentially explosive atmospheres. Examples include places where work activities create or release flammable gases or vapours, such as:

– Vehicle paint spraying,

– Metal processing facilities, where explosive metal dusts may form.

– Processing units of raw materials that generate fine organic dusts such as grain flour or wood manufacturing units.

The potential for explosive atmospheres can exist in a range of mainly industrial locations such as mines, factories, agricultural silos, and oil and gas platforms, water and other chemical processing environments.  There is a wide range of products intended for use in such areas, including control equipment and sensors, transformers, fans, pumps, compressors, fork lift trucks, and lighting.
