On March 9, 2018 a “limited breach” of the tailings dam at the North Tailings Facility of the Cadia Mine tailings impoundment occurred in New South Wales, Australia. The area of the failure is approximately 270 m across, with a back-scarp of about 100 m. The runout was about 370 m. All things considered, it could have been worse. The mine owner, Newcrest Mining Limited, has ceased mining operations while they deal with the issue, and has begun radar monitoring. No additional movement had been detected as of last week. More information can be found in the briefing given to shareholders, and in the initial press release. Image: Newcrest Mining Limited
On September 30, 1935, President Franklin D. Roosevelt dedicated the Hoover Dam, telling the 10,000 people gathered at the ceremony that it was a “great feat of mankind” destined to reshape “the geography of a whole region.” The American Society of Civil Engineers calls it one of the “Seven Modern Civil Engineering Wonders.” In honor of this significant milestone for this fantastic structure, I’ve collected some facts and figures, news articles, information on the bypass bridge, and some concerning news about the future of the dam’s ability to supply power.
