What is Through-the-earth mine communications?

The through-the-earth mine communications is an innovative tool of communications that we use to connect the people who work in mines and keep them connected to the surface. This way, miners can be aware of what is happening around them, not to be caught unawares when emergencies arise. 

By tracking, relaying, and monitoring situations in real-time through radio or satellite communication systems, people working at ground level can manage potential accidents before any harm is done. 

This technology is currently being used in South Africa for mining and oil industries. It is also used in the military, law enforcement, and security industries. 

When a mine accident happens, the first thing that rescuers will do is stop any traffic from entering or leaving the mine immediately. Any vehicles on site are then evacuated to a secure area not to be harmed during rescue operations. The people who work at ground level are then notified of the situation to take appropriate action.

How does Through-the-earth mine communications work?

Communication is made possible through an extensive array of underground antennas that are placed strategically at different levels. These antennas receive and transmit information from the mine so that authorities know what is happening inside. This way, rescuers can accurately locate people and vehicles down below.

Through-the-earth mine communications use both Radio and Satellite technology to transmit signals from the mine to the surface. The transmitter sends out information while the antenna receives it so that people at ground level are kept informed about what is going on below. The signals are encrypted to ensure that no one down below can eavesdrop on the transmissions.

Through-the-earth mine communications are best used in situations where there is a risk of a collapse or cave-in. An example of this is the case of Deepwater Horizon, which occurred on April 20, 2010, when an oil rig exploded and sank, causing an oil spill. The rescue operations were carried out using Through-the-earth mine communications since it was impossible to carry out a rescue without knowing what exactly was at ground level. 

The Deepwater Horizon oil rig was manned by 126 people, most of whom were brought to safety in lifeboats. The remaining 11 missing workers, however, were trapped down below at the bottom of the sea. Before a rescue operation could proceed, the exact position of those trapped had to be determined. This was when Through-the-earth mine communications came into play as they were used to send a tight-beam signal down through the Earth’s core and locate a worker who had managed to get out of his cabin before it exploded.

Becker Communication’s Through-the-earth mine communications

Through-the-earth communication is a solution for mine communication problems that the Becker Communication Company has well researched. It works in conjunction with a universal translation service to allow people in mines to communicate with the outside world. The firm has also made progress in providing solutions and improvements to its existing service.

Their recent research and development includes “a new, more efficient way to transmit information through a radio to be transmitted from coal seam sensor tags placed into mine workings.”


Communication is an integral part of being able to escape from a mine disaster. However, the techniques that rescue workers use to communicate with each other and the miners depend on their location. Through-the-earth communication and other radio and satellite methods relay messages from rescue workers through the Earth’s crust. The distance between each location can vary depending on how deep in the ground they are, however. 

The most important part of any rescue operation is accurately knowing where all the workers are located. If a worker is found and saved quickly, then it will save more lives and be more effective as an overall rescue operation. It has also been shown that having a tight-beam radio system can make rescuers even safer as it will provide them with clearer communication with other members of their teams.

What is a VHF Leaky Feeder System

What is a VHF Leaky Feeder System

In the 1940s, American scientist Sidney Darlington had the idea of a VHF leaky feeder communication system. This is one of the most popular communications systems used by ham radio operators all over the world today. VHF leaky feeders are mainly used for long-distance communication, typically between base stations and mobile transceivers; they don’t offer any features like data or transactional capability.

VHF leaky feeder systems are a type of analog modulation technique used for communication between transmitter and receiver. A VHF leaky feeder is a communications system that uses amplitude modulation (AM) processes to link radio stations, base stations, repeaters, and mobile units using modulated carrier wave transmission signals. 

This technique transmits a continuous stream of information from one location to another. The individual bits of information are sampled every 20 microseconds. The information is encoded as audio tone frequencies, which vary in a highly narrow range.

How does the VHF Leaky Feeder System work?

A continuous stream of bits (or digital data) is modulated onto the carrier radio wave using an analog modulation technique. 

A modulator receives the digital information and converts it into an audio tone. The audio tones are then transmitted at the desired frequency (1.8 MHz in this case). Once the receiver detects the transmitted tone, it extracts the information and displays them on its screen. 

Because the frequency of the transmitted tone is constant, any receiver can detect it regardless of its distance from the transmitting station. Thus, a VHF Variable Frequency Modulated (VFm) system consists of a transmitter and a receiver linked together using a leaky feeder circuit. 

VHF leaky feeders work with amplitude modulation (AM). The information to be transmitted is converted into variation in the amplitude of an electrical signal. In the case of VHF variable frequency modulated systems, the information is encoded into the audio frequencies. The AM signal is then transmitted through a leaky feeder that takes time to reach the receiver site. 

When it reaches the receiver, the tone frequency is picked and separated from other noise frequencies before finally displaying it on the screen in bits. This process is known as detection. 

The VHF variable frequency system consists of three parts- transmitter, receiver, and a leaky feeder transmission line that connects both stations. 

The transmitter section consists of the modulator, control, and audio stages. The modulated signal is converted into an audio signal using modulation techniques. The output of the modulator is coupled to the antenna input of the transmitter through a low pass filter and modulator amplifier. The VHF leaky feeder system sends information at varying audio frequencies picked up by an FM detector in the receiver. 

This then scans through menu files or incoming traffic. The FM detector scans the incoming signal and displays transmitted information on the screen. 

The VHF leaky feeder circuit works by sending audio tone frequency (as above). The number of bits in a character or word is sent as a reference frequency picked up by an FM detector. The tuned circuit scans through all frequencies to find the right one once it detects the tone frequency. A bandpass filter separates the frequency from other noise—the extracted bits of information display on the screen. 

These are not used for communications only, but several applications such as code division multiple access (CDMA). CDMA networks work similarly to a VHF system. Like a VHF system, they are much shorter than their analog counterparts since they use digital information instead of audio tone signals.

Becker Varis VHF Leaky Feeder System

The VHF Leaky Feeder System from Becker Communication Company is a type of antenna system that consists of two orthogonal VHF antennas called Spillikins. It operates at frequencies between 150 – 170 MHz (TV) and 175 – 221 MHz (FM). This antenna system is designed for high efficiency in the installation and maintenance stages.

It is possible to point or rotate the two antennas in any direction, thus providing an omnidirectional radiation pattern while still achieving a maximum gain. The system has no main reflector surface, which avoids potential wind loading problems with dishes in high wind areas susceptible to icing or vandalism problems. It also includes a weatherproof case for corrosion protection and easy transportation.


The VHF system is a simple yet effective way of sending data. It is used to send encrypted digital data or any message such as weather forecast, shipping alerts, etc. It works similar to short wave radios, except it uses less frequency bandwidth, and more data can be sent over a shorter distance. This enables smaller transmitters and receivers to be used as compared to the conventional analog systems. If you would like to learn more then contact us today!

Benefits of Mine Radio Systems

Mine Radio systems are a wireless communication system used in mines to transmit data between the various mine equipment such as semaphore, lighting, first aid, and location. It is also used to transmit information to other mining regions through wired or radio line transmissions. 

The use of these systems has become widespread among the mining community due to their reliability and ease of installation. Mine radio systems can be found in nearly any size mining operation, from small coal mines to massive gold mining operations like Barrick.

Advantages of Mine Radio systems

There are several features of mine radio systems that make them a great fit for any mining operation:

  • They are a safe, dependable, and reliable communication system that does not rely on the physical connectivity of wires like other similar systems.
  • The simple installation is often accomplished in only a few hours and requires little technical experience or training.
  • Mine radio systems communicate information to and from any area within a specified radius. They do not require the use of mains electricity or the installation of costly cables into mines.
  • They are flexible in the amount of information available for information purposes.
  • Mine radio systems are a cost-effective communication solution. They often provide greater functionality than wired alternatives that do not offer many of these same advantages.
  • They can be used in an emergency as a backup communication system.

How do the Mine Radio systems work?

As you can see in the above diagram, a transmitter sends a signal to the receiver. The receiver then decodes the signal and displays it on the screen. If your transmitter and receiver are correctly functioning, you will be able to see all of the information that they are receiving from your system. Information sent by these systems can include text information displayed along with graphics like analog clocks or simple designs. 

These radio systems are typically found in smaller operations where people do not have access to computer technology for their operations. Mine radio systems are also very cost-effective as they can be installed in multiple locations within a mine. For example, a mine operator might have a mine radio system installed in the office where employees can communicate with one another or to the control room.

As the demand for these systems increases, so does the size of these mining operations. It is common for many large mining operations to have three or more individual separate installations, each having different functionality and data coming into the system. Many of the larger mines do not even have a system in the office; instead, they use mains power to communicate. 

As you can see, these systems are an effective solution for many different situations in mining operations. As more and more mines begin to implement mine radio systems, it is important for people to understand how they work and their benefits.
