RealTrac Underground Mining - a multipurpose system for enhancing industrial security and overall efficiency of mining operation. The system consists of the following products:



RealTrac Positioning

The product is aimed to detect positioning of miners, mining machinery and other objects on various mine levels, in faces, stopes (mines) using various radio technologies.

Issues to be solved


Monitoring of personnel access levels

Monitoring of personnel access levels

Due to geo zones with various access levels, an operator is always informed if the personnel are trespassing any forbidden zones or not. The reporting system enables to find out the access levels system violations and to prevent such incidents.

Personnel positioning monitoring in underground mine

Personnel positioning monitoring in underground mine

An operator can receive data in real-time not only about the positioning of miners and vehicles, but also about the motion path of the monitored objects within certain period of time. 

Control of work-time and time spent in a geofence

Control of work-time and time spent in a geofence

The RealTrac system enables to register the personnel entry and exit times from a certain geofence. This helps to monitor positioning of personnel in certain zones of a mine and to alert a miner about the need to get to the surface.  The data about events is stored in server up to 10 years. 

Personnel emergency notifications

Personnel emergency notifications

In case of emergency, the system sends notifications about evacuation need to all miners. Also, the system enables to use additional warning devices like: sirens, alarm reporting etc.

Personnel detection and evacuation in cases of emergencies

Operating principle and components

The system provides a situational awareness of the environment around a vehicle; detects presence of vehicles, personnel or objects within the pre-set zones. As soon as any object, vehicle or personnel equipped by RealTrac Collision Avoidance tag enters the pre-set zones, the system emits tangible, audible and visual signals.

Alerts are emitted by:

Audible warning from machinery, activation of sirens or horns

The Vehicle Beacon Unit is installed on a vehicle in amount of 4-6 units depending on vehicle size and configuration and enables to detect personal tags (trackers) or VBUs installed on other machinery. 


Independent operation


The system has embedded software and is completely independent from other systems and data networking. If a feedback channel is implemented, the system can transmit data about the detected cases of dangerous proximity, collisions and other relevant data to RealTrac server. 

This enables to make further analysis of the incidents and to form activity reports.



RealTrac Voice communication

The product provides digital, anti-interference, mobile communication in underground mine enabling communication between operator, underground and surface personnel.

Issues to be solved

The product provides mobile voice communication in two directions:

Portable voice communication miner-miner

The portable voice communication between miners is arranged via one voice channel and all intercoms of a miners’ team are tuned to this channel. Also, all the conversations are recorded.

Portable voice communication miner-control room

The voice communication between miner and mine operator is arranged via the main voice channel (Channel 0). Due to a possibility to integrate the RealTrac Voice Communication with a company’s telephone connection, a mine operator can forward a miner’s call to any other phone of the company or even cell phone and landline. At the same time, all the calls in the main channel are recorded. 


Key benefits

  • Digital radio communication; stable operation within the entire territory of a mine within the radio coverage zone of the nearest access point;

  • Distance range from intercom to access point: up to 500 meters;

  • An intercom is attached to certain employee in a system interface;

  • All conversations are recorded;

  • The RealTrac positioning enables to detect the positioning of personnel that are using the voice communication;

  • In case of emergency, the system can send alarm notifications to intercoms of all personnel 


Operating principle and components
