Ok Tedi Mining Limited (Ok Tedi) has announced the successful deployment and commissioning of the ArcSAR Neo slope stability monitoring radar system, becoming the first company in the world to acquire and deploy two units of this next-generation radar technology.
In a statement issued by Ok Tedi, the company said the successful deployment of the ArcSAR Neo slope monitoring radar system provides a clear view of ground conditions, allowing monitoring to continue during network interruptions, and can automatically adjust its position after being moved for blasting activities. Given these features and the present ongoing challenges with the pit operations been narrow and deep, the new system is particularly valuable in Ok Tedi’s complex mining environment.
The ArcSAR Neo was developed by IDS Geo Radar, a Hexagon company, and is designed to be most advanced in monitoring and detecting ground movements at an early stage. Its introduction demonstrates Ok Tedi’s ongoing commitment to improve safety, embrace innovative technology, and promote continuous improvement in geotechnical risk management.
According to the statement, the system since its commissioning has demonstrated significant improvements in data quality, reliability, and confidence in decision-making.
Equipped with advanced processing technology and sophisticated monitoring software, the ArcSAR Neo substantially reduces common sources of interference, including atmospheric conditions and signal distortions. This has resulted in fewer false alarms and more eligible slope stability assessments.
The radar's enhanced resolution has enabled the detection of very small ground movements at an earlier stage, allowing potential risks to be identified early and managed proactively. This capability strengthens Ok Tedi's ability to maintain safe, productive, and efficient mining operations while effectively managing geo-technical hazards.
The technology is said to be designed to perform in challenging environments; the ArcSAR Neo incorporates durability improvements that address historical issues such as water ingress, ensuring reliable operations in Ok Tedi’s high rainfall conditions.
The new radar systems are being supported by trained and certified Ok Tedi technicians, with additional technical support from IDS GeoRadar specialists.
While previous ArcSAR systems have delivered dependable service for many years, the ArcSAR Neo introduces a new level of precision, reliability and operational value.
Ok Tedi will continue to assess the long-term performance of the technology under site-specific conditions and progressively integrate its outputs into the company’s broader strategy.
The combined training and development of its technical personnel will help maximise the benefits of this strategic investment.
The successful acquisition and deployment of the ArcSAR Neo radar system is Ok Tedi's commitment to leveraging innovative technology while improving safety outcomes, strengthening operational performance and supporting sustainable mining practices for the future.
