In the high-stakes world of mining, reliable communication isn’t just a convenience – it’s a lifeline.
Very high frequency terrestrial trunked radio (VHF TETRA) has emerged as a “game-changer” in the way mining companies approach communication challenges.
Communication challenges and risks in mining
Operating in mining environments presents a host of communication challenges that impact efficiency and safety. The remote locations of many mining sites, coupled with expansive and rugged terrain featuring underground tunnels, deep pits and rocky landscapes, pose significant obstacles to signal transmission.
Mines are inherently hazardous environments due to risks like cave-ins, explosions, dust, and toxic substances. Users often face signal degradation, limited coverage, and connectivity issues, especially in remote or underground areas.
Electromagnetic interference (EMI) from heavy machinery and equipment is a significant issue, disrupting wireless signals.
Multi-path propagation exacerbates communication problems, causing signal distortion and fading as radio waves bounce off surfaces such as walls and machinery, particularly in underground mines with reflective surfaces.
Compliance with safety regulations, such as those set by regulatory bodies like the Mine Safety and Health Administration (MSHA), is essential. These standards govern transmitter power levels, antenna installations, and frequency usage to help mitigate interference and uphold worker safety.
VHF TETRA presents a solution for large-scale mining environments by consolidating multiple networks into a single system that operates above and below ground.
Above ground, VHF signals travel far in open areas, providing a cost-effective and reliable communication solution with clear audio, even in noisy conditions. Below ground, the ability to propagate signals in tunnels via a leaky feeder makes it well suited to complex underground networks.
VHF TETRA is safe, reliable and robust. The system is built to withstand the mining environment, offering interference resistance to explosives, dirt, dust and heavy machinery. Its reliability helps to improve personnel safety, providing prompt alerts for evacuations or coordinated rescue efforts.
VHF TETRA can also be cost-effective. It requires minimal infrastructure and maintenance and can help streamline workflows and boost productivity, making it a more sustainable choice for long-term deployment in mining operations.
Sepura’s VHF TETRA solution for mining
Recognising the unique communication needs of the resources sector, Sepura has developed a suite of TETRA products tailored specifically for mining environments: the SC Series.
“Combining the reliability and security of TETRA with the longer range signal propagation at VHF frequencies plus the powerful audio processing of the SC Series radios sets a new standard for communication excellence in the mining industry,” Sepura said.
According to Sepura, the SC Series allows mining organisations to establish a robust VHF TETRA solution with many benefits:
Enhanced
VHF solutions provide enhanced coverage in expansive outdoor areas, underground tunnels using leaky feeder, and complex terrains.
Streamlined infrastructure
Extended coverage means fewer communication infrastructures are needed, resulting in reduced set-up and maintenance costs, as well as quicker deployment across sites.
GNSS location services
Integrated GNSS (global navigation satellite system) services allows for tracking, triggers and emergency response, improving situational awareness and safety.
Rugged design
Built to endure mining conditions, with magnetic shielding to mitigate metal dust build-up, the radios are equipped with water and dust-resistant technology. Their inherent haptics are designed for use with gloved hands, ensuring performance in all conditions.
Versatile communication modes
Access various communication modes like SMS, SDS, direct (DMO), trunked (TMO), and gateway operation, along with feature-rich applications for enhanced functionality.
Efficiency and safety features
AppSPACE links teams, devices and systems by transmitting operational data across TETRA, Wi-Fi and Bluetooth. This connectivity allows for streamlined workflows and ensures crucial situational awareness information reaches the appropriate individuals quickly.
AppSPACE allows customised applications to be added to radios already in the field without disrupting any critical TETRA communications.
Emergency response capability
Features like Man-Down and Lone Worker help keep workers safe by detecting emergencies, and the SmartView app locates individuals in an emergency.
Streamline processes
The AutoMate app automates tasks, helping mining companies streamline processes, improve worker safety, and protect valuable assets. RadioAsset allows fleet managers to access crucial information such as software versions and battery manufacture dates, providing valuable maintenance information, as well as the ability to run an audit to keep track of the products.
Wireless programming
Over-the-Air Programming allows for secure configuration updates and asset management over approved Wi-Fi networks, simplifying maintenance and upgrades.
“VHF TETRA stands as a game-changer for mining safety, offering unparalleled reliability, coverage and functionality tailored to the unique demands of the industry,” Sepura said.
“With Sepura’s innovative VHF TETRA solutions, mining operations can achieve new levels of efficiency, productivity and, above all, safety.”
