Two methodologies are typically employed in monitoring tailings dams/levees:
- internal deformation, settlement, load, and pore pressure;
- external deformation and leakage.
Both methodologies should be employed. External monitoring is important but internal stability of the structures always provides leading indicators of failure, i.e. it provides more time for mitigation of potential failures.
This webinar will outline several methods for each type of monitoring, and outline their strengths and weaknesses; including Satellite Radar (InSAR), Ground-Based Radar, In-Place Inclinometers, Shape Accelerometer Arrays, Settlement Sensors, Pressure Cells, Piezometers, GPS, Robotic Total Stations, Wire Extensometers, and Weirs.
