April 2019 www.coalage.com 33 highwall management continued viding knowledge of the full history of potential instabilities in sectors where geotechnical information was not available. In addition, the ease of installing the system at different lo- cations met the mine's expectation of being able to use the I-Site XR3 laser scanner for other survey applications. Maptek said the implementation at Shougang took place in a staged sequence, starting with delivery of equipment and accessory require- ments for optimal installation of the system, through to completion of the training. • Day 1 of the implementation required Shougang to provide accreditation passes, a safety in- duction, the equipment check- list, and installation of the Sentry system at the monitoring point. • On the following day, Maptek gave a Sentry presentation to Shougang personnel, and as- sisted in setting up the areas of interest, the Wi-Fi network con- nection for remote monitoring, and a test run definition of alert parameters. • The final day included checking remote access, theoretical train- ing for Shougang personel, prac- tice using the Sentry System, and wrap-up of the implementation. New Software Brings Faster Data Analysis In September, IDS GeoRadar an- nounced it was partnering with Roc- science to integrate deformation monitoring data from IDS's slope monitoring radars into slope stabili- ty numerical models in Rocscience's Slide3 and RS3 software. This integra- tion, according to IDS GeoRadar, is a first in the industry and a step for- ward toward intelligent slope design. IDS GeoRadar, an Italian company, is part of the Hexagon group. The company said the next releas- es of Slide3 and RS3 will allow users to overlap radar maps onto numerical model results using the georeferenc- ing data imported from IDS GeoRa- dar interferometric radars. The latest ArcSAR technology now makes it pos- sible to capture deformations every minute on the entire slope. IDS GeoRadar said its ArcSAR is the first and only radar in the mining industry to provide 360° pit coverage from a single equipment unit. The system offers long-range capabilities (5,000 m) along with short scan time (360° in 40s; 180° in 20s) and built-in GNSS for auto-geocoding. According to IDS GeoRadar, these advances will lead to faster geotech- nical analysis. The radar data will be integrated through a streamlined workflow that will allow geotechnical engineers to focus on modeling and slope analysis rather than waste time importing and converting files. The company also announced a new implementation of its ArcSAR technology, the HYDRA-X, a high-res- olution, high-accuracy, quick-de- ployment monitoring radar system. It is claimed to provide spatial reso- lution two times finer than any other slope-monitoring radar. IDS GeoRa- dar said that by close monitoring of hanging benches over working areas or elements at-risk, HYDRA-X can measure sub-bench scale instabilities. With a maximum scan range of 800 m, at-risk areas can be safely monitored even for the smallest rock movement. HYDRA-X features on-site pro- cessing and alarming, an optical HD camera with visual imagery linked to radar data and refreshed scans every 30 seconds. Information is available for quick reaction, even in the case of sudden accelerations, and people are immediately alerted in the field. Its design allows convenient travel requiring only a light vehicle, and sin- gle-person operation. HYDRA-X can be supplied with a combination of solar panels and fuel cells, providing 60 days of full autonomy with almost zero maintenance. The company said HYDRA-X represents the "perfect solution" for monitoring smaller mining opera- tions where radar monitoring can contribute to the optimization of slope design and extraction planning by improving overall risk manage- ment. Its versatility is well-suited for focused monitoring of tailing em- bankments and working sectors in strip coal mines. Listening In Radar, LiDAR and total station/re- flective prism systems are designed IDS GeoRadar's HYDRA-X features an optical HD camera with visual imagery linked to radar data and refreshed scans every 30 seconds. Maximum scan range is 800 m (2,625 ft).
