Non-Contact Monitoring for Tailings Dams and Surrounding Slopes
Remote Deformation Monitoring. Continuous Data Tracking. Enhanced Operational Safety.
Tailings Storage Facilities (TSFs) require continuous monitoring to assess the structural condition of tailings dams, embankments, and surrounding slopes. Detecting abnormal displacement and deformation trends at an early stage is essential for supporting operational safety and effective risk management.
Hu Entropy Tech provides an integrated structural health monitoring solution combining the Online Visual Tracking System, passive optical targets, data acquisition and transmission equipment, and a cloud-based monitoring platform.
Using advanced Digital Image Correlation (DIC) technology, the system enables non-contact, multi-point displacement monitoring of selected areas across tailings dams and surrounding slopes. Measurement data can be transmitted to the cloud platform for real-time visualization, historical trend analysis, and configurable alarm notifications.
The solution can also integrate with geotechnical monitoring sensors, including vibrating wire instruments and other compatible data acquisition devices, to support a more comprehensive monitoring network.
Key Monitoring Parameters
- Dam Displacement – Tracks horizontal and vertical displacement at selected monitoring points across the dam structure.
- Settlement – Monitors vertical movement of selected dam and surrounding structural areas.
- Slope Deformation – Tracks displacement and deformation trends across surrounding slopes and potentially unstable areas.
- Crack Opening – Monitors changes in crack width using appropriately arranged visual targets or dedicated measurement configurations.
- Deformation Rate – Analyzes displacement changes over time to identify accelerating deformation trends.
Key Features
1. Non-Contact Visual Monitoring
Uses optical measurement and passive targets to monitor selected locations without installing displacement sensors directly at every measurement point.
2. Multi-Point Deformation Tracking
Tracks multiple targets within the camera’s field of view, supporting simultaneous monitoring of selected areas across dams and slopes.
3. Remote Monitoring and Data Transmission
Supports remote data transmission and centralized monitoring, helping reduce the need for frequent manual site inspections.
4. Continuous Deformation Analysis
Records displacement data over time, allowing engineers to review historical trends and assess changes in structural behavior.
5. Intelligent Alarm Notifications
Configurable alarm thresholds help identify abnormal displacement or deformation trends and provide timely notifications.
6. Integrated Monitoring Architecture
Can work alongside vibrating wire data acquisition instruments, industrial RTUs, and other compatible monitoring sensors to consolidate different types of engineering data.
7. Cloud-Based Data Management
Provides centralized access to monitoring data, visualization, historical records, and alarm information through a remote platform.
Typical Applications
- Tailings Dam Deformation Monitoring
- Embankment Displacement Monitoring
- Surrounding Slope Stability Monitoring
- Tailings Storage Facility Settlement Monitoring
