TECHNOLOGY, DETAILS

High technology without doubt has played a very important role during the two-month-plus rescue process. The rescuers have used heavy excavators to dig out a tunnel, a special "capsule" to lift out the miners, and a projector to provide entertainment and a distraction to their ordeal, and even passed bacterium-free copper fiber socks to the miners to prevent dermatophytosis, a fungal infection of the feet.

The rescuers also designed out a 12.7 cm-long hollow column, which was loaded with food and medicine and passed to the cavern in which the miners were trapped through a vent-pipe.

The rescuers paid close attention to detail throughout the rescue process. For example, they invited U.S. nutritionists to work out a special diet to ensure each miner would take in less than 2,200-calories every day.

When lifted out the shaft, the miners, who have been in darkness for a long time, were each given a pair of sunglasses worth 450 U.S. dollars to protect them from the sudden exposure to the sun.
