Our partnership with FeichunTM is a testament to our commitment to continuous improvement in safety and operational standards.” - Mr Independent Non-executive Director ROSEBERY, TASMANIA, AUSTRALIA, August 9, 2024 /EINPresswire / -- In a strategic move aimed at bolstering safety and enhancing operational efficiency, Australia's MMG Group has successfully upgraded the electrical infrastructure at its Rosebery Mine by installing the latest generation of FeichunTM trailing cable mining . This significant enhancement forms part of MMG's ongoing commitment to maintaining the highest safety standards in the mining industry, particularly in its high-demand operations.

Enhancing Safety and Efficiency in Mining Operations
The mining industry, by its very nature, operates in environments where the safety and reliability of electrical systems are paramount. Mining trailing cables are a critical component in these environments, tasked with supplying power to a variety of heavy-duty, mobile equipment, including miners, draglines, shovels, drills, bucket wheels, and conveyors. These cables must endure the harsh conditions typical of mining sites, including extreme mechanical stress, exposure to chemicals, and fluctuating environmental conditions.

The newly installed FeichunTM mining trailing cables at Rosebery Mine are specifically designed to meet these challenges. These cables are engineered to handle high voltages ranging from 5kV to 72kV, which are necessary for powering the large machinery used in mining operations. Additionally, they are capable of carrying significant current, translating to the delivery of substantial energy in megawatts and horsepower. This power capacity is crucial for the effective operation of mining equipment but also presents significant safety risks if the cables are not properly designed and maintained.

Advanced Cable Design for Maximum Safety
Each conductor within the FeichunTM trailing cable is surrounded by a grounded metallic sheath, which acts as a protective barrier. This sheath helps contain any electrical faults that might occur, preventing them from spreading and causing more significant issues. In some cases, the cables also include an additional outer shield around all the conductors, which is also grounded. This additional layer of protection further reduces the likelihood of electrical failures posing a danger to personnel or equipment.

In the event of an insulation failure, the design of the FeichunTM cables ensures that any blast of current from the phase conductor to its shield is immediately detected by the mine's protection systems. These systems, typically involving protective relays, are designed to monitor ground faults or any phase-to-phase faults continuously. Upon detecting such a fault, the relays automatically trip the circuit breaker supplying the affected cable, thereby isolating the fault and preventing potential accidents.

Integrated Safety Systems
To complement the robust cable design, FeichunTM trailing cables are equipped with a pilot wire, also known as a ground check. This wire runs parallel to the main conductors within the cable and is monitored in series with the system. If a break occurs in the pilot wire, the monitoring system assumes that the cable has been damaged or separated, triggering an automatic system shutdown. This proactive approach ensures that any physical damage to the cable is immediately addressed before it can result in a more severe incident.

Another critical safety feature integrated into the FeichunTM cables is high-impedance grounding. This technique is employed to limit fault currents and reduce voltage-to-ground during electrical contacts, bringing the levels down to a range that is more likely to be survivable in the event of an accidental contact. High-impedance grounding is particularly important in mining environments, where the potential for high-energy faults is significant due to the extensive power demands of the equipment.

Operational Benefits and Industry Standards
The benefits of upgrading to FeichunTM trailing cables extend beyond enhanced safety. These cables are also designed to improve the overall operational efficiency of the Rosebery Mine. The high flexibility of the cables allows them to handle continuous bending and flexing without degrading, which is crucial in mining operations where cables must follow mobile equipment as it moves around the site. This flexibility reduces the strain on the cables, leading to fewer instances of wear and tear, and consequently, lower maintenance requirements.

Moreover, the durability of the FeichunTM cables ensures a longer service life, even under the harshest conditions. The outer sheath of the cables is constructed from materials that are highly resistant to abrasion, chemicals, and extreme temperatures. This durability not only enhances the reliability of the power supply to critical mining equipment but also reduces the frequency of cable replacements, leading to significant cost savings over time.

The FeichunTM mining trailing cables installed at Rosebery Mine fully comply with international safety and performance standards, including AS/NZS 2802 , which governs the construction and use of reeling and trailing cables in mining and general industrial applications. Compliance with these standards is crucial for ensuring that the cables can withstand the mechanical, electrical, and environmental stresses typical of mining operations. By adhering to these stringent standards, MMG Group demonstrates its commitment to maintaining a safe working environment while achieving high operational efficiency.

Strategic Importance and Future Implications
The decision to upgrade to FeichunTM mining trailing cables is a strategic move that aligns with MMG Group's broader objectives of enhancing safety, sustainability, and operational excellence across its mining operations. The Rosebery Mine, located on Tasmania's West Coast, is one of the key assets in MMG's portfolio, producing zinc, lead, copper, and precious metals. As such, ensuring the mine's operational efficiency and safety is critical to the company's overall success.

The integration of cutting-edge technology, such as FeichunTM trailing cable mining, positions Rosebery Mine as a leader in the adoption of advanced safety systems within the mining industry. This upgrade not only improves the immediate safety and reliability of the mine's electrical systems but also sets a benchmark for best practices that can be applied across other mining sites within MMG's operations and beyond.

"Our partnership with FeichunTM is a testament to our commitment to continuous improvement in safety and operational standards," said an MMG Group spokesperson. "By investing in the latest generation of mining trailing cables, we are ensuring that our operations at Rosebery Mine remain at the forefront of technological innovation and safety compliance."

The successful implementation of FeichunTM mining trailing cables at Rosebery Mine marks a significant milestone in MMG Group's efforts to enhance safety and efficiency.
