Mine monitoring workshop for surveyors

March 27th, 2017, Published in Articles: PositionIT


Aciel Geomatics hosted a GeoMoS Monitoring User Training workshop at the Leriba Hotel in Centurion recently. Delegates from De Beers, Debswana, AngloAmerican, Kumba Iron Ore and Geita Gold attended the workshop, which focused on intermediate and advanced slope stability monitoring for mine surveyors.

The workshop started off with a general overview of Leica’s GeoMoS automatic monitoring solution which celebrates its 20th anniversary this year. The software comprises two main applications, Monitor and Analyzer. Monitor is the online application responsible for sensor control, data collection and event management, while Analyzer is the offline application responsible for analysis, visualisation and data post-processing. In South Africa the GeoMoS system is mainly used to monitor slope stability on mines, but it can also be used to monitor infrastructure such as dams, tunnels, bridges and high-rise buildings.

Michael Rutschmann, Leica’s senior product manager for structural monitoring, outlined the latest enhancements to the system with a particular focus on the integration of terrestrial lidar and interferometric radar. The brand’s total stations, GNSS receivers, and digital levels can be connected to the system which is designed for continuous monitoring.   The system also supports the integration and connection of meteorological and geotechnical sensors to measure environmental effects and conditions. Supplementing geodetic measurements with geotechnical data assists users to determine the causes of detected deformations.

The second day of the workshop focused on GeoMos Now a web-based application that provides total, round-the-clock access, to monitoring project data via any web-based device. Visualisations are provided in real-time enabling users to check-up on the status of projects by using a range of easy-to-interpret maps, graphs, images, tables, automatic reports and deformation scans. Users can also enrich their geodetic and geotechnical monitoring measurements with GIS shape files and raster data.

During the workshop, attendees were able to pose questions to Rutschmann and obtain his expert advice on how to make effective and efficient use of the monitoring system for their particular environments.
