Becker Tunnel Communication System

A tunnel communication system has become an essential piece of tunneling through mountains and mining sites in a coordinated effort. Tunnel communication systems are a unique solution for managing the problem of solving communications issues in mining. Mining environments require extensive communication and this is not always easy in construction sites where projects can extend kilometers underground. The environments make it difficult to implement various elements of construction and make sure that all of the teams are coordinated and effectively communicating. As vehicles can travel extremely efficiently it’s not easy to make sure that workers and vehicles are out of harm’s way without some form of deep real-time communication.

A tunnel communication system is a module that uses a high frequency radio system with a two-way level of communication without a traditional radio or landline telephone system. TCS systems are made with a wireless repeater system that allows voice communication outside of the tunnel and it worked as an excellent alternative to traditional telephone or radio communications that would otherwise be effective in a tunneling site. TCS systems offer a series of features that can improve the construction processing tunnel and mining sites and it can also reduce the risk of injuries on mining sites as well.

Using advanced wireless communication systems can make sure that safety is improved at every level of the mining site. Heavy construction vehicles and equipment require ongoing communication and the radio repeaters will allow for communication outside of the tunnel as well as the deep end of the tunnel system. These types of communications are instrumental in remote locations and times where vehicles are going to require communication in the tunnels. TCS frequencies are considerably lower than most radio systems and there’s no need for a direct installation or landline. TCS  frequencies can also continue to work in smaller size mines as well as large-scale industrial sites where power supplies are not always reliable. These systems work well in remote locations and they can use a cellular-based system that’s suitable for any mining site. 

The tunnel communication system can be placed on board a tunneling vehicle or it can be run through a series of modules throughout the tunnel system. Providing continuous two-way communication between these supervisors, excavators, operators and managers is important and with these tools, you can make sure that every level of communication and coordination takes place amongst your staff.

What Is The Purpose of A Leaky Feeder?

Leaky feeder communication systems are underground mining solutions using tunnel environments. These systems are used by cabling professionals and manufacturers to provide a system designed for optimal communications. Coaxial cable is not generally designed to provide quality communications but a leaky feeder system can provide a cable run along with a series of titles that receives radio waves and functions like an antenna. The cable is leaky as it has slots and gaps along the outer conductor which allows for the radio signal to leak out or leak into the cable along the length. The entire cable can become somewhat of an antenna for radio signal and provide a simple system of communications reportable transceivers carried by personnel. Transmissions from the receivers are picked up by the feeder and carried to other parts of the tunnel along with two-way communication and throughout the entire radiating line. Signal loss along the feeder does occur but this is usually at frequencies under 1 GHz. Installing a series of repeaters throughout the network line retains a clear signal and ensures that signals of almost any type can be transmitted along the lines in perfect clarity. Various antennas are often included in the system to provide a higher frequency band of communication. Here we talk about the purpose of a leaky feeder system!

Leaky feeder communications are quite common in the mining industry and they are used as a tool for wireless communication between miners. The system is used for primary communication where the transceiver is small enough to be comfortably worn by each minor throughout an entire shift. These systems of communication can often include headset communication or a small walkie-talkie which is easy for communicating through daily use in the tunnel and even in industrial communications as well. Leaky feeder communications are often delivered in up to 4G coverage and they provide a distributed system of communication that can work for everything from industrial buildings to mining sites. With coordination in antennas and repeaters signals can be booted even in some of the most hostile environments on Earth. 

Leaky feeders today have been more like to include piddling communications for an underground network that is in New York subways or the London tunnel system. Features have also been modified with metallic strips and radiofrequency identifying data, this can help with monitoring and repairing the network as well as with the process of inventorying various tools used in mining and industrial sites. These types of improvements to Leaky feeder systems represent revolutionary new ways that companies are working to improve efficiency and the quality of communication throughout industrial sites worldwide.

If you’d like to learn more about the purpose of leaky feeder systems for your business or you’re curious about how these systems could be integrated into your industrial site, contact us today to learn more. We have been establishing leaky feeder communication systems and radio communication systems that work for major industrial sites for decades. We are ready to introduce new systems that could improve the safety of your mining site.

The Importance of Radio Communication In Tunnels

admin Mining Communication
The Importance of Radio Communication In Tunnels

Radio communication in tunnels is a requirement for mining sites. Electronic communications have taken over for mining sites in emergencies, from radio support, and more. Walkie-talkies or cell phones have been rendered as an inefficient manner for many mining sites to communicate. With the majority of mining sites turning to a low-frequency radio or wifi emergency signal in tunnels, we are seeing changes to the nature of mining communications worldwide.

Low frequency radio communication in tunnel sites keeps work safer and it ensures that miners can maintain communications even through extensive rocks and deep mining sites. Enabling communication can ensure that emergency personnel can be reached, that workers are able to reach people in the tunnels and that ongoing communication and productivity are maintained. 

Radio communication needs to be maintained for safety, as well as for visibility in any mining site. Communication can be difficult in mining sites with a wealth of equipment as well as with many areas that could be hidden from view. Heavy traffic throughout a busy mining site will require communication and radio communication provides a sense of security for many workers throughout a tunnel. If there is an emergency in a tunnel or a type of evacuation that may be required, a radio could serve as a lifeline for a group of people in a tunnel setting. 

People will need to stay informed in a tunnel and radio will help direct the evacuation. Radios can ensure that all workers can follow the appropriate directions for their equipment and be directed throughout the process.

For traffic flow, radios are also important. Whether you are going to be moving material from deep in the mine site or bringing new equipment down, sometimes heavy equipment will need to be directed and areas need to be kept clear. Having reliable communications for these times can ensure that there is no difficulty with traffic jams and ensure that everyone can be well managed in a mining site.

Seamless Communication In Mining Tunnels

The communication process for mining tunnels is as seamless as picking up a cell phone in most cases. Tunnel workers are able to pick up devices and speak with clarity. The base station or communications hub will have access to all the information that is needed instantly and the teams can communicate effectively through the devices provided. Radio communications are bolstered by antennas on the ground or throughout the mining site to boost the low frequency radio, there could also be a series of wifi hubs for communication backup and data transfer. 

If you are interested in learning more about mining communications and tunnel radios, contact us today. We can assess your business for mining communications support and tunnel radios to outfit your company. 

What is a Leaky Feeder Cable?

What is a Leaky Feeder Cable?

A leaky feeder is an electrical cable that transmits and delivers electricity. This cable allows liquid to lubricate inner conductors and prevents electrolysis corrosion. Leaky feeders can be used in applications where it is impossible or impractical for them to remain dry. Here we explain what a leaky feeder cable is exactly.

There are many types of cables that can transmit electricity. An electrician or an electrical engineer must make the right choice when choosing the best type of cable to transmit electricity.

Let’s say you want to install a high-definition TV in your living room. You may choose to use speaker wire to connect your TV. It is available in lengths of up to 100 feet, and has two copper conductors within each jacketed sheath. You will need to use 24 gauge wire to get 720p resolution.

This wire is not thick enough to be a 2-conductor-cable. This same-sized cable is also not suitable for carrying current to certain devices such as speakers or electric drills.

Wiring that is extra-heavy-duty requires a cable with four copper conductors in each jacketed sheath. This cable is often used in large industrial settings such as hospitals and large factories that use many types of current-carrying equipment.

A thinner jacket is used to prevent a leaky feeder cable from being tampered with by code. To make the cable waterproof, a special coating is applied inside. It becomes saturated with water and an electric charge forms between the copper conductors.

Varis Smartcom(r.150IS) Leaky Feeder Cables are ideal for anyone who needs to provide power to an AV device. With its durability and quality, this cable will be a reliable companion. This cable is ideal for people who don’t want cables to break while they are in use, or anyone who is always on the move!

Becker Communications has been a leader in the development of more advanced electrical mining communication systems for over 15 years. They expanded their reach into surface mining, railways, tunneling, and added wireless communication systems, handheld radios and tagging and tracking systems as well as gas monitoring.

Wireless Radio Networks Save Miners Every Day

Wireless Radio Networks Save Miners Every Day

Leaky Feeder Communication

The most advanced solution for mining communications was until recently, a leaky feeder. Leaky feeders can transmit wireless radio network frequencies that save miners! They are similar to coaxial cables, which transmit a signal from one point to the next. Coaxial cables are usually protected by a copper sheath around the cable to stop the signal from leaking throughout its length. You might not be capable of detecting signals with a radio from the other endpoint if the network has a long cable, unlike a wireless radio network.

Leaky feeders can be very different. Leaky feeders have small gaps in their shielding that allow the signal to pass instead of being covered with a copper shield. These gaps create a restricted wireless radio network environment. To compensate for the loss of signal, line amplifiers and repeaters increase the signal at regular intervals on the cable. Leaky feeders can be interfaced with wireless devices. They can transmit and receive radio signals over the cable. Data can include voice, video, and computer data. You can control stationary equipment such as water pumps with radio receivers by using signals from the leaky feeder for a wireless radio network. To receive and transmit signals, you must still be within 300 feet (91.4m) of the cable.

A leaky feeder cable has one advantage: it can be laid down while you excavate a mine. Splitters can be used to send different lengths of cable along different routes. Flexible cable makes it easy to move the network around corners and curves. If necessary, you can feed cable directly down a hole. Leaky feeder systems have a few downsides. Communications will stop if the cable is cut. Multiple leaky feeder cables can cause interference in the system. Leaky feeder radio frequencies are more common in the high-end spectrum. These frequencies can’t penetrate rock very well.

Four leaky feeder systems have been approved by the Mine Safety and Health Administration (MSHA), which is the US government agency responsible for overseeing safety concerns in miner safety.

Mesh Networks

Mesh networks can be used in place of leaky feeders. A mesh network does not require a cable as a leaky feeder system. Let’s look closer at how wireless mesh networks can make mining safer. A mesh network transmits a wireless signal using a system called nodes. A node is basically a wireless router. The node is equipped with special software that allows it to communicate and collaborate with other nodes. Dynamic routing is used by the nodes to determine the best route for data transfers. The node location, data traffic, and other environmental factors can all influence the best route. Some nodes are mobile, most importantly.

Nodes

A minimum of one node must be in a fixed location. This node acts as a bridge between the mesh and larger networks like the Internet. A radio tower connected to the Internet could serve as the main fixed point for a mine. Multiple fixed nodes are a common feature in mines to provide a strong foundation for the mesh network. Wireless mesh networks operate on one of two wireless radio network frequencies, 2.4 gigahertz for the IEEE 802.11 protocol or 900 megahertz for the IEEE 802.15 protocol. Both have issues broadcasting signals around corners so it may be necessary for the network to have a node at every corner. These protocols did not interfere with any other communication systems in mines, according to the MSHA.

The nodes do not have to be large. Many are approximately the same size as a typical wireless router. This makes it simple for miners to attach nodes on heavy equipment. Nodes can be used even when in motion, but at a slower bit speed. This means that many mining vehicles can transport the nodes. To monitor the mine conditions, you can also wire nodes to sensors. The node can transmit signals to the rest of the network if danger is averted. You can also build electronic badges that communicate with the mesh network. This allows the network to track individual miners’ locations. Different nodes will detect the badge of the miner as the miner moves through it. The mining company can determine if a section of the mine is hazardous and then evacuate it. To communicate with the surface, miners can use personal radios and voice-over-Internet protocol ( VOIP) phones.

While mesh networks can be used to prevent accidents, what happens if a part of the tunnel collapses? Unfortunately, mesh networks’ wireless protocols aren’t very efficient at reaching the earth. You need a system that works on extremely low frequencies to achieve this. A through-the-earth system (TTE), was tested by the Mine Safety and Health Administration (MSHA). It could penetrate rock up to 270 feet (82.3 meters). Data transfer was slow at 20-30 characters per minute, with an accuracy of 80 percent at depths up to 630 feet (192 meters). A TTE system could be capable of broadcasting further through solid ground. The downside is the slow data transfer speed. However, the MSHA discovered that TTE systems can interfere with other communication systems in mines.

To get back to the surface, miners use a wireless radio network. A reliable communication network can make the difference between life or death, considering how hazardous their job is. Contact us today for more information!

 

 

Underground Mine Communications: A Brief History

admin Mining Communication
Underground Mine Communications: A Brief History

A reliable and efficient communication system is essential for creating a safe, productive, and efficient mine. The history of materials extraction technology dates back many centuries. However, the era of underground mine communications systems can be traced back to the last century.

Just as above ground, the invention of the telephone triggered the mining communication revolution. Prior to the invention of the telephone, mine shaft communication was primarily based on bells and whistle signaling systems. Mines started to use ruggedized telephones that were connected via cables strung through the mines in the early 20th Century. Although the phones were the same as the ones above ground, they were enclosed in cast iron housings to protect them from the extreme temperatures, humidity, dust, or corrosive environments that can be found in a mine. Most phone systems were either based on a magneto (crank-ringer) format. These systems are still widely used today. They use a party-line format with one telephone per section and additional phones at key locations above or below ground. These systems are easy to set up and maintain due to their hard-wired design. However, miners will often have to stop working in order to use them.

The introduction of hoist-rope and trolley-carrier-based communication systems was made possible by the increased automation of mining in the 20th century. These carrier current systems use electrical connections to drive electric haulage systems. Because they are piggy-back systems, both systems are simple to install and provide strong mechanical strength. They are dependent on carrier frequency.

Radio made underground mine communications possible. Nicola Tesla investigated the possibility of using extremely low frequency (ELF), and naturally occurring minerals in mine structures, as a means of TTE (through-the Earth) communication. In the 1940s, South African gold mines were home to the first successful TTE system. In-mine research of ultra-high frequency and very high-frequency communications (VHF/UHF), began in the 1970s. Wave propagation in mine environments is difficult because of the complex topography, dynamic nature of mining operations, and the elements of the mine structures. Radio signals behave differently underground than in above-ground mines.

The “leaky feeder” mining communication system is a hybrid system, which was developed in the 1970s. The system combines both wired and wireless communication to ensure robust and flexible communication even in difficult mine environments. The backbone of the system is the leaky feeder cable. This is a coaxial cable with sections of the outer shielding that are shaved off during manufacture to allow RF signals to “leak out” (or leak in). It functions as an antenna and provides a communication path for radio transmissions within the mine. A repeater is connected to a leaky feeder cable. This cable is then extended into the mine with line amplifiers and repeaters to compensate the signal loss. Mining communications technology has advanced just as much in the last century as mineral extraction technology. We now have wireless communication systems which allow people on the surface to communicate with equipment and people miles below them, increasing safety and efficiency, as well as safety.

Mining Safety Starts With Communication Devices

Mining Safety Starts With Communication Devices

Good communication devices will help you avoid accidents in the mining industry.

If you work in the mining industry, it’s your responsibility to stay safe and be aware of dangers. Good communication devices, such as radios or personal alert systems can help make this possible.

Security personnel in the mining industry use hand signals to communicate. A signal is a special movement that lets others know what’s going on. You can use special hand signals to help avoid accidents in your mining operation. For example, if you’re operating a transport vehicle, you might point your thumb to the right to let others know you’re turning right.

Some companies require miners who work underground to wear electronic communication devices called personal alert systems (PAS). These devices work like radio beepers and can send a signal to let workers know they need to head surface.

A radio is another device that will help keep miners safe. It’s dangerous when miners work underground, where it’s hard to see each other around equipment and buildings. Radio communications allow miners to stay in contact with the surface, which reduces the risk of underground accidents.

Communication devices help to avoid accidents in mining sites. Workers from above the ground or below the surface are susceptible to fragmentation of rock and rockfall, literally raining down on them from above or blast from below. This is why cave in protection systems, such as rock bolting and cage bolting, are needed. When the ground may collapse beneath you, having a communication device that automatically alerts your colleagues to that fact can help save your life.

Fortunately enough, the mining industry has dramatically improved its safety record over the last century. The use of mining communication devices and PAS systems has become more widespread over time. It has helped reduce hazards in mining operations.

Your company should also have an emergency medical plan for accidents and injuries. Another good safety practice is to train your employees on the safe use of the equipment and how to respond to emergencies. They must also know how to use communication devices such as beepers or personal alert systems.

If you’re ever in a situation where you think someone needs help, don’t hesitate to call for assistance. The person you’re calling may be unable to hear or understand what you’re saying due to hearing loss or impaired vision. However, by using a voice transmitter or telecommunicator, you can relay your message to others and they will call for help.

In most cases, a network of beeper devices is able to recognize an emergency situation without the need for an operator to press the button. For example, miners can go underground using their handheld beepers as they descend if a mine cave-in occurs. One person on the surface can also use this as an opportunity to contact others out on foot who can assist in the rescue effort.

Usually, the beeper signals are composed of a number of different tones that tell someone exactly where on a map your location is. The signal considers the surrounding noise, which makes it easier to locate you. Beepers are also useful in areas where there is no cell phone service. The beeper devices will then work as a distress signal or sign that indicates an emergency situation.

According to many statistics, 75% of an employee’s safety depends on communication between them and their supervisors (Ryan & Laughlin, 2009). Therefore, it is important that supervisors understand how to use communication devices (beepers) and PAS systems in the mining industry. The communication devices that can be used are portable or hands-free.

First and foremost, it is important for supervisors to know that they can always contact their employees using PAS systems or other communication devices such as beepers. It is also important to be aware of the consequences of not following safety guidelines when using communications devices such as beepers and personal alert systems.
