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.

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.

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!

The leaky feeder system permits the control and monitoring of electrical equipment, such as pumps and fans. The Intrinsically Secure I.S. When used with the Becker I.S., the Leaky Feeder can provide 100% coverage for underground mines. Two-way portable radio.

SYSTEM OPERATION

This system provides seamless two-way communication throughout underground tunnels or mines. Leaky feeder antenna cables are used to achieve this. The radio signals from Head End, which are usually located at the surface, are transmitted underground via the leaky feeder cables. The signal can also be easily retransmitted on the surface and can cover several kilometers.

LEAKY FEDER CABLE 

Coaxial cable was designed to retain as much signal as possible and block external signals. Leaky Feeder cables are designed to leak or radiate radio signals out and allow signals in from remote radio transceivers located within 50-200 meters of the Leaky Feeder Cable. Line Amplifiers or boosters are installed along with the Leaky feeder cable runs, nominally every 350m. They help sustain signal levels over long distances.

SYSTEM DESIGN 

Certified Becker communication engineers design leaky feeder systems in consultation with customers and meet all compliance requirements.

REPAIRS AND EXTENSIONS 

As a mine grows, leaky Feeder cables will need to be repaired and extended. It is important to make quick connections and repairs in order to minimize downtime and ensure reliable operations. These requirements can be met by the Becker splice device. Line splices are used to join two sections together, where signal amplification does not apply, or to repair damaged sections. To properly terminate the system, line terminations are placed at the Leaky Feeder cables.

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!
