Open-pit geomechanical monitoring
Measurement of pit-wall movement and soil parameters to assess changes over time.
Discuss your facility
What we monitor
- Pit-wall and slope displacement
- Ground mass condition
- Groundwater level
From on-site measurements to information for staff
Parameters and instrument selection depend on the structure, operating conditions, and existing systems.
On-site monitoring
We select measurement points and instruments for the changes being monitored.
Collection and transmission
We connect measurements to the shared system using the available communication and infrastructure.
Monitoring and events
We set up archives, change visualization, and alerts for responsible staff.
Purpose
The system monitors deformation of open-pit walls and the surrounding ground mass. Continuous measurements help locate unstable areas and assess how slopes change over time.
Monitored parameters
- Horizontal and vertical movement of the ground mass
- Deformation of pit walls, benches and slopes
- Hydrostatic and pore-water pressure within the ground
Monitored assets
- Open-pit mine walls
- Benches and slopes
- Ground and rock mass in the mining area
Possible system components
The following families and instruments are examples. The final selection is defined by the project.
Level sensorsPLLG D01 Water level sensorMeasures groundwater levels in observation boreholes. Transmits readings over RS-485 for long-term monitoring of foundations, hydraulic facilities, and slopes.
Ground extensometersEX-CMG Ground displacement sensorMeasures ground movement relative to a stable point. An Invar wire connects the sensor and anchor; changes in distance are recorded by the monitoring system.
Level sensorsPLLG Pore pressure sensorMeasures water pressure between soil particles. Used to monitor seepage, ground foundations, dams, quarries, and landslide processes.
Level sensorsPLLG Pressure piezometerMeasures water pressure in pressurized boreholes, pipelines, and tanks. Can be incorporated into wired or wireless data acquisition systems.
Level sensorsPLLG-D22 LoRaWAN piezometerBattery-powered piezometer with LoRaWAN measurement transmission. Monitors water level and pressure without a permanent cable connection to the server.
Level sensorsPHG Standpipe piezometerStandpipe piezometer for hydraulic structures. Its sectional design includes a riser pipe, filtered intake, and sump.Let’s discuss your task
