SLOPE STABILITY station. The RIEGL monitoring workflow allows the system to be removed temporarily for other jobs and later reinstalled, with automatic re alignment compensating for offsets and orientation changes.”
That preserves consistency in the monitoring time series while giving operations more flexibility in asset utilisation. Instead of locking equipment into a singlepurpose function, the scanner remains adaptable to changing mine requirements. This ability to preserve the monitoring series after temporary interruption is important for real mine operations. Equipment may need to be inspected, maintained, moved for priority survey tasks, or re-installed after site changes. Automatic re-alignment reduces the risk that such operational realities break the continuity of the monitoring record.
For mining companies under constant pressure to improve productivity and reduce exposure, RIEGL says these three operating modes form a practical bridge between conventional surveying and digital operations. Static surveys provide precise reference models. Mobile mapping captures broad areas efficiently. Permanent installations deliver the temporal density required for geotechnical surveillance.
“ Because all three modes rely on the same underlying sensor logic, mines can combine them into a coherent monitoring concept rather than a collection of disconnected measurement campaigns.”
But Gaisecker says the real transformation begins when LiDAR data acquisition is linked with autonomous processing and operational decision support.“ In that context, the Monitor + App is not just an add-on for the scanner. It is the software environment that turns the instrument into an autonomous monitoring platform. Developed for the VZ-i series, it combines monitoring, design comparison, slope analysis, and prism observation within one application environment and allows the complete workflow to run directly on the scanner.”
A particularly distinctive element of the Monitor + App is the way it handles data internally. Instead of relying on the repeated transfer and comparison of full point clouds in an external office workflow, the scanner transforms the measured data into an imagebased representation of the 3D scene. The distance information is encoded with millimetre resolution in the RGB channels of an image, while the local surface normal is stored in the alpha channel. This creates a compact but information-rich model of each monitoring epoch.
Reutech Mining and two decades of a complete radar monitoring approach
In 2026, Reutech Mining is celebrating 20 years of developing geotechnical monitoring solutions for the global mining industry. The
company told IM that its work has been shaped by one constant: trust built over time, in real conditions, alongside clients and partners.
“ Mining does not allow for shortcuts and decisions carry weight, as conditions change. Pressure is real and in this environment, trust is not given upfront. It is built through consistency, presence and performance over the long term. For Reutech Mining, that journey has unfolded site by site, slope by slope and decision by decision. Every system deployed, every challenge addressed and every improvement made has contributed to a shared journey with the clients and partners who rely on its technology in demanding mining environments.”
It says this two decade journey has shaped what Reutech Mining offers today.“ Not simply three radars or individual pieces of technology operating in isolation. But a complete custom radar monitoring solution, bringing together different radar technologies, intuitive software, visual monitoring, flexible deployment options and expert support around the specific requirements of each mine. From detection to interpretation and response, Reutech Mining brings radar, visual monitoring, software and expert support together in one connected approach.”
The company also says that different mine slopes present different monitoring
