“The world’s largest man-made excavation – a US copper mine – has been shut down by an enormous landslide that smashed roads and buildings and left two-thirds of the pit base buried. Nobody was hurt in the collapse at the massive open-cast Bingham Canyon Mine, run by Rio Tinto-owned Kennecott Utah Copper – largely because workers had been evacuated amid several weeks of warning signs the ground was going to shift. Kennecott is the second largest copper producer in the US, supplying about a quarter of the country’s copper, the company’s website states.”
