Tailings dams are used to store byproducts from mining operations. These dams are often constructed using some of the byproduct itself as a structural component and are built to hold more material as needed.
As the materials in a tailings dam are often hazardous to humans and the environment, they are considered a safety hazard and must be checked regularly. Drones are used to quickly get into the air and monitor the tailings dam for any leaks or potential fault points. A drone can also be used to check the level of the tailings dam.
