8 . After more than 2 months trapped in a collapsed copper (铜) and gold mine in the desert, all of 33 Chilean miners (矿工) were rescued Wednesday. With ingenuity and cutting-edge technology, the men have survived for 69 days, some 700 meters underground fending off hunger, anxiety and illness in a record-setting feat of survival. How did they survive the ordeal? Have a close look.

Before the miners were reached, they survived for 17 days on food already stored in the emergency shelter. They rationed themselves to 2 spoonfuls of tuna, half a cookie and a half-full glass of milk every 48 hours. Then a 6-inch diameter bore hole allowed food and water supplies to be sent down to the mine. Doctors then put the men on a solid diet of meat and rice, with a strict 2,200-calorie limit to keep them slim enough to fit in the evacuation shaft, which is just 66cm in diameter.

Yonny Barrios Rojas, 50, used knowledge gained on a nursing course he attended to administer medicine to the group and perform daily health checks.

“I was with God and I was with the devil. They fought and God won,” Mario Sepulveda, the second to be rescued, told CNN. He said he grabbed God’s hand and never doubted that he would be rescued.
