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.

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.

Worlds Largest Miners Pledge Net Zero Carbon Emissions By 2050

admin Mining
Worlds largest miners pledge net zero carbon emissions by 2050:

The world’s top mining companies are committing to a goal of reaching a net zero carbon emissions by 2050 or sooner. Under the International council on mining and metals, a group of members have made a new commitment to reach a net-zero scope of greenhouse gas emissions by 2050. The year could mark a pivotal step in the industry as over 28 mining companies will be taking on initiatives to significantly scale back their greenhouse gas production. 

The announcement comes as a reaction to the UN climate gathering that will be achieving a more ambitious climate action plan. Over 200 countries signed into the 2015 Paris agreement and miners have established a plan to get on board with what their national government has agreed to. 

Miners that include the Anglo American company, Rio Tinto, BHP, and others are working with environmental activists as well as their shareholders to commit to new net-zero carbon emissions plans for 2050. The commitment represents a chance to cut emissions by up to one-third in the global metals and mining industry. The 28 companies that are a part of the initiative have sites in 50 countries and over 650 locations. The goal is to continue to report annually and progress the process of decarbonizing in an annual sense too. 

Mining is set to take place under a challenge to decarbonize and there are many companies that are producing metals like nickel and copper that are going to be crucial to the future of this industry. Indirect and direct emissions are going to be lowered first by using more electric vehicles, renewable energy, and a reduction in equipment that relies on diesel. 

The targets are going to look first into industries like the iron ore and steel industry which require carbon to produce. Carbon-free steel has not been proven but further research into this technology could lead to a revolution in manufacturing while reducing carbon emissions. 

If these companies are able to continually run their mines and also stay committed to reducing their carbon emissions, we will see a vast reduction in carbon emissions from the industry. The mining industry has faced considerable pressure from investors and governments because it is responsible for around 4-7% of the total greenhouse gas emissions on a global scale. Around 1% of the total methane emissions occur from coal mining and a significant share of carbon emissions occur from this industry as a result of heavy use of diesel. 

To stay on track, mining companies will need to reduce their greenhouse gas emissions by up to 30% by the year 2030 to follow the agreement of the Paris goals. Further scaling efforts to reach a net-zero will need to drop significantly in the 2 decades left to the deadline. 

The shifting demand for minerals in electronics and green technology are causing many companies to prioritize their efforts into mining sites that include mining for cobalt, nickel, lithium, copper, and rare earth elements for the production of more electric vehicles, equipment, and greenhouse gas reducing electronic substitutes. 

If your company is interested in signing into this agreement or you would like to learn more about technology that you could be used to reduce your greenhouse gas emissions, contact us today.

A gas monitoring device is designed to measure the level of gasses inside and outside a building. These dynamic monitoring systems are installed on-site by safety managers or contractors and the goal is to ensure that there is a minimal degree of gas leakage that occurs from the surrounding environment. These systems are common in construction and mining sites and the ongoing monitoring is responsible for keeping miners safe and ensuring the equipment can be kept safe as well. These systems can monitor for a wide range of gas types including:

Methane

Volatile Organic Compounds

Carbon Dioxide 

And more

Gas leaks in a construction site are often seen as a signal towards poor health and they can often cause ongoing complications. Ongoing exposure to gas will lead to the chance of fatalities and chronic sickness and disease. Gas leaks in a construction site need monitoring and having a gas monitoring Device will ensure that the risk of a gas leak does not occur. 

Gas leaks in mining sites can be poor for your health and it can even lead to the chance for a fatality. Gas monitoring systems will be a useful system for allowing work to continue without issues and with ongoing assurances to the workers. 

Gas Monitoring System Technology

Gas monitoring Devices are used quite widely in many industries and they are often a focus in food production, manufacturing, mining, and more. Gas monitoring is also quite popular to include in constructions for schools and hospitals. Detectors are often hooked into a central computer which is responsible for sending readings to a control center to determine if there is a form of gas or pollutant in the air. If the computer system determines that there is a gas present, it will sound an alarm to alert the people in the area and to ensure that an evacuation plan can occur until the gas has a chance to dissipate.

Alarms for monitoring will ensure that within seconds of an unsafe presence of gas, an alarm can sound to alert employees to put on masks or to use the structured evacuation plan that they have created. The use of a gas monitoring alarm is a crucial step to ensuring that people can properly monitor their chemical gas exposure and take themselves out of a situation where their health could be at risk.

What is a Leaky Feeder Cable?

admin Mining Communication
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!

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!
