Non-Contact Monitoring for Tailings Dams and Surrounding Slopes

Haytham’s solution uses the Online Visual Tracking System, passive targets, data transmission, and a cloud platform for continuous deformation monitoring of tailings dams and surrounding areas.

Dam Displacement · Settlement · Slope Deformation · Crack Opening · Deformation Rate

Non-Contact Visual Monitoring

Using oblique optical-axis imaging and sub-pixel tracking, the system remotely measures 2D displacement at multiple points across the dam body and slopes.

Key Features

▪ Long-Distance Monitoring

Remote measurement from stable observation locations

▪ Multi-Point Measurement

One system monitors multiple points simultaneously

▪ Sub-Millimeter Accuracy

High-precision displacement measurement under suitable conditions

▪ Continuous Monitoring

Suitable for long-term unattended operation

▪ Automatic Alerts

Multi-level alerts based on displacement and deformation rate

▪ Sensor Integration

Supports pore water pressure, groundwater level, rainfall, reservoir level, and vibration data

Monitoring System

Visual Sensing → Data Transmission → Cloud Platform → Early Warning

Supports solar/mains power, 4G/5G, Ethernet, and fiber, with real-time dashboards, historical trends, report export, and API integration.

Applications
