RFID technology is used in various ways in the mining industry to improve efficiency and profits. One way RFID is used is to track the location of equipment. This helps to reduce delays caused by human error, as well as optimize activities for greater profit. Another way RFID is used in the mining industry is to track the status of maintenance and repairs. This allows mining companies to schedule downtime better and avoid costly delays. Finally, RFID is also used to monitor safety conditions in mines to ensure that miners are working in safe conditions and can quickly respond to any potential hazards. Overall, RFID technology is a valuable tool for the mining industry (see also our post about mine productivity).
WHY RFID IN MINING
The mining industry is one of the most dangerous industries to work in. There are many hazards that workers face on a daily basis, including exposure to toxic chemicals, heavy machinery, and falling debris. In recent years, the industry has been looking for ways to improve safety for workers. One way that mining companies are doing this is by implementing RFID technology.
RFID stands for "radio frequency identification." This technology uses radio waves to identify and track objects. RFID tags can be attached to equipment, vehicles, or even people. When an RFID reader scans the tag, it can collect information about the object that it is attached.
Mining companies are using RFID tags to track equipment and vehicles. This helps them to keep track of where their assets are, and it also helps them to prevent theft. In addition, RFID tags can be used to monitor equipment maintenance. By tracking when equipment is due for servicing, mining companies can minimize downtime and keep their operations running smoothly.
RFID technology is still relatively new but has already proven valuable for the mining industry. As this technology continues to evolve, even more uses will likely be found in the mining industry.
RFID IN MINING: USE CASES
Controlling access to mine sites: RFID can control access to mine sites. By tagging employees' ID badges with RFID tags, companies can track which employees are entering and exiting the site. This information can be used to improve safety by ensuring that only authorized personnel are on site.
Logistic distribution of supplies: RFID tags have many benefits over other tracking methods, such as barcodes. For example, they are more durable, can withstand harsh conditions, do not require a line of sight to be read, and can store more data than barcodes. This makes them ideal for tracking products in the mining industry.
RFID tags can provide a wide range of information about the products they are affixed to, making them ideal for tracking in the mining industry. There are two main ways that RFID tags are being used in mining operations:
- Open circuit: The same RFID tag that the supplier uses is reused by the mining operation to track the products inside the mine.
- Closed circuit: The mining company puts new RFID tags on the products distributed in the mine environment. This allows them to track the products easily and prevents mix-ups.
In open circuit supply logistics distribution, the supplies labelled by the provider are received at the general warehouse and will be distributed to areal warehouses from this building. Later on, it is possible to further redistribute the labelled supplies to other surface or underground warehouses. There are many benefits of using RFID in mining supply logistics. For example, it can help improve inventory accuracy and visibility while reducing labour costs. In addition, RFID can also help reduce losses due to theft or damage.
Tracking personnel: RFID tags are used in the mining industry for people localization, as each worker is given an RFID tag. The RFID readers are located at strategic points throughout the mine, such as the main entrance and level entrances. In drifts or ramps of an underground mine, the antennas are located based on readers' range and spacing. The goal is to decrease the personal location uncertainty areas. This allows the rescue and first aid teams to know exactly where everyone is in case of an emergency.

Evacuation and rescue: Safety is of the utmost importance in underground mining. In the event of an accident, every second counts in terms of rescue and recovery. Radio frequency identification (RFID) technology plays an increasingly important role in helping to keep miners safe. It is vital monitoring miners to know each worker's exact location and where the rescue and first aid teams are.
In an accident, RFID can help first responders locate individuals who may be trapped. It is possible to activate alarms immediately and implement evacuation protocols, monitor and guide rescue teams, do the same with workers and conduct them to safe places or operating lifts, stop truck traffic and stop works affected directly or indirectly by accident.
This system has proved to be very effective in ensuring the safety of workers in mines. In one instance, a worker who was injured and unable to move was quickly found and rescued by using this system.
Managing explosives: RFID can also be used to track the location of explosives in a mine. This information can improve safety by ensuring that explosives are only used when and where they are supposed to be.
Detection areas: RFID is used in the mining industry for proximity warning systems. These systems use RFID tags to track the location of workers and equipment and then warn the vehicle driver if someone or something is in his proximity. This helps prevent accidents by ensuring the driver is aware of his surroundings. These systems can also be used to track the location of assets and inventory, which can help improve efficiency and productivity in the mining industry.
To do this, it is necessary to put an RFID tag and an antenna on the vehicle, which will act as a radar system, informing the driver to avoid a collision or unsafe situations. In addition, the RFID reader on the truck warns about the proximity of people and equipment by emitting sound and light.
Boundaries of safety zones can be adjusted using algorithms that evaluate the intensity of the received signal, generating, for example, a growing level sound. The proximity monitor system requires an RFID wireless net and suitable software. This software could use algorithms to adjust the range of detection zones, generally between 10 and 300 m.

Integral safety in underground mining
As companies seek to improve safety and efficiency in their operations, RFID technology plays an increasingly important role in the mining industry. RFID tags are being used to track equipment and personnel underground, helping to ensure that everyone is accounted for in an emergency. The tags can also monitor equipment performance and manage maintenance schedules. In addition, RFID-enabled sensors are being deployed to track environmental conditions underground, providing valuable data that can help improve safety and productivity.
A technology like this can be used to create an integrated safety system constituted of different parts:
- Personnel registry and monitoring
- Security: includes restricted operational areas, shelter locations, explosive caches
- Supplies acquisition and distribution
- Equipment registry and tracking: must consist of equipment in particular restriction areas, nearby authorized workforce etc.
- Equipment collision control and the restricted area administration
- Equipment maintenance scheduling
- Assignment and monitoring emergency team
- Transport and traffic regulation, the traffic lights
TAKEAWAY
RFID technology in mining can provide many benefits, such as improved safety, efficiency, and security. By tracking the location of personnel and equipment, companies can ensure that everyone is where they are supposed to be. Additionally, companies can prevent unauthorized personnel from entering the site by controlling access to mine sites.
RFID technology can be used for various purposes in the mining industry, such as controlling access to mine sites, tracking personnel and equipment, and managing explosives. RFID technology in mining can provide many benefits, such as improved safety, efficiency, and security.
