SLOPE STABILITY MONITORING
FieldHHC combines a powerful , simple GUI with impressive , intuitive features for controlling survey workflow .”
Maptek says better mine conformance using laser scanners can increase highwall and bench safety , with improved wall stability
and conformance reporting using Maptek spatial solutions .
Maptek Sentry 2021 is now on the Maptek Workbench platform , delivering enhanced interoperability for monitoring , analysing and reporting on surface movements . A new ribbon interface in Sentry Office increases the visibility of functions and enhances the user experience . Scans can be easily transferred between Sentry and PointStudio and zones created in one application appear in the other , for easier analysis . Sentry scans can now be coordinated to mine grids in the field , streamlining interoperability . Sentry databases now contain single scenes to improve data management and enhance performance .
Maptek also offers solutions for mine design conformance . “ Accurate , timely data around conformance to design eliminates problems before they escalate and dramatically improves operational safety and productivity . Transforming the volume of data collected on a site into timely decision support information presents a challenge . It is not sufficient to complete mine design compliance checks after excavation has
finished . Understanding what went wrong after the fact does not resolve issues . Feedback about design compliance must happen during excavation .”
Maptek conformance solutions are based on comparing detailed point cloud information captured daily against the short term design . Multiple sections can be created from one scan to precisely define how an as-built wall , bench or drive matches a particular design .
One key advantage of the laser scanning approach is the ability to measure and compare active mining faces from a distance . Reviewing critical data in the field allows teams to act safely and efficiently to keep mining on track . All underground and open pit mines , including quarry and dredging operations can use Maptek
design conformance tools .
Short term design requires constant refining on a daily basis . Timely conformance reporting has implications for key design decisions on parameters like depth to floor or wall angle .
Feedback available at the stages where it can have a positive impact on the quality of the design delivers maximum benefit to the design process . Design conformance creates a robust quality feedback loop around one of the critical production processes in a mine . It reduces variance and provides timely , accurate information about conformance to design along production quality principles .
When functional stakeholders and management can quantify material variability at each stage , confidence is boosted in the business proposition .
Business costs associated with implementing digital conformance systems are relatively low . Workflow processes do not change significantly for stakeholders . Only the tool being used to guide a process changes , offering a result that is much faster and easier , more accessible and accurate .
Planning assumptions are improved by monitoring and optimising the modelling , design and execution of a mine plan . It is no longer necessary to delay milestone reporting . Maptek provides the technology to make this achievable for day to day operational improvement .
Maptek FieldHHC is the latest scan control system for R3 mkII laser scanners . Design conformance on the Maptek FieldHHC supports production goals through an intuitive field process that delivers immediate and accurate conformance data , allowing staff to make informed decisions in the field . Conducting in-field conformance directly from laser scans allows operations to : n Actively monitor conformance without interrupting production n Increase highwall and bench safety , with improved wall stability n Resolve issues quickly without waiting for in-office processing “ The in-field tablet controller FieldHHC has long been the surveyor ’ s trusted field assistant . It follows standard survey set up and scan georeferencing , enabling users of Maptek laser scanning systems to enjoy the most efficient survey experience .
RIEGL VZ-i Series and DMT SAFEGUARD
The open architecture of the RIEGL VZ-400i and the RIEGL VZ-2000i 3D Terrestrial Laser Scanner allows customising the scanner for complex data acquisition and processing tasks by means of Python scripts and Python-based Apps . RIEGL ’ s Online-Waveform-Processing technology ensures high quality data . Plus 24 / 7 fully remote operation is proven . Laser scan data is processed by integrated apps in real time on the scanner , final results are visualised via a web-viewer tool .
Based on the example of DMT SAFEGUARD , it has been shown that the scanners can be integrated in various applications , demonstrating their high degree of flexibility . DMT GmbH & Co KG has integrated the RIEGL laser scanner into its DMT SAFEGUARD monitoring system based on its ability to be part of a user-specific system integration by means of open system architecture meaning it it possible to offer tailored solutions to customers in the mining and infrastructure sectors . The new system provides real-time , exhaustive geospatial information and all decision-relevant parameters such as deformation values on demand from anywhere on the globe . In case of status changes users are notified promptly by a push warning service . DMT SAFEGUARD is a web-based data management and geoinformation system ( IoT platform ) for all types of monitoring tasks in the construction industry , mining and for infrastructure projects , with which geotechnical monitoring data can easily be collected in a
The RIEGL VZ-400i and VZ-2000i 3D terrestrial laser scanners have been integrated into the DMT SAFEGUARD monitoring platform , to offer innovative and tailored monitoring solutions for the mining and infrastructure industry
