Catastrophe revisited disastrous flow failures of mine
Abstract. Catastrophic flow failures have occurred with alarming frequency in mine tailings dams and dumps of discards and other mine waste. In recent years, catastrophic flow failures have also occurred in dumps of municipal solid waste and even in what were intended to be carefully controlled and well-engineered landfills.
May 13, 2019 · Up until a few years ago, the mining industry in South Africa took a reactive approach to environmental impacts caused by mining activities. Unfortunately, tailings-related impacts are severe and can result in loss of life, long-term damage to the environment and ground water pollution.
Evolution of tailings dams. To look back briefly on the evolution of tailings dam engineering in South Africa, dams were initially very small when mining first started in the 1870s, reflecting the limited scale of the mining itself. Essentially, the tailings disposal practice was uncontrolled, with tailings just pumped into rivers, streams, and lakes.
