Tailings dam & slope stability monitoring
Solutions for effective risk management.
Ground Motion Monitoring
Ground motion monitoring provides complementary insights into the impacts of natural or anthropogenic activities on a dam's foundation and surrounding terrain. This technique involves the use of sensors to detect even subtle ground movements, such as those induced by seismic events, blasts, machinery or nearby vibrations from other sources. In the context of tailings dams, ground motion monitoring, often coupled with interferometric techniques, enables the early detection and alerting of notable impacts to the dam that may warrant further inspection or action.
Interferometric Structural Integrity Monitoring
Ambient noise interferometry is a powerful tool that goes beyond traditional seismic monitoring. By analyzing ambient noise signals traveling between sensors, it unveils variations in velocity within the structure itself. This method provides a unique view into the structural changes and velocity perturbations, allowing for early detection and proactive monitoring. It enables a more comprehensive understanding of the health and integrity of various earth structures, making it an invaluable asset for long-term, ongoing, and short-term monitoring projects.
Tilt Monitoring
Tiltmeters are a valuable tool used in the monitoring of tailings dams. They can be strategically placed on key points of the dam or containment structure to continuously measure and record any changes in tilt. This real-time data can help in early detection of potential problems, allowing for timely intervention and preventive measures. As tailings are complex structures, effective monitoring often involves integration of a variety of sensors. Nanometrics SiteAlert platform provides a unified platform for data visualization and alerting such that monitoring can be done proactively ensuring the safety and stability of tailings storage facilities and minimizing the risk of environmental disasters.
