Tailings Dam Safety Specialists
When it comes to safety around tailings storage facilities (TSF), it is imperative to have an effective monitoring program in place. According to Klohn Crippen Berger (KCB) associate and senior geotechnical engineer James Penman, the starting point for dam safety monitoring and management is understanding the critical failure modes for the structure. “Dam safety failure modes are ways in which the dam fails, to the point that containment is lost and tailings and/or water flow out,” he said. Catastrophic dam failures typically happen through the three major failure modes of overtopping, instability and internal erosion (or piping). “Slope instability has been the most prominent failure mode in recent times, namely the Samarco and Brumadinho dam failures in Brazil. “Overtopping is less prominent in tailings…
