The miners stranded some 2,300 feet (700 meters) underground in Chile will need to keep to a routine and rely on each other to help their chances of survival, experts have said.
Rescuers are racing to reach the 33 men trapped in the north of the country after their copper and gold mine caved in nearly three weeks ago. Officials warn it may take up to four months to dig a rescue shaft and bring the men to the surface.
In the meantime, messages, flashlights, medicine and food will be passed underground to ensure their survival.
How are the men likely to be coping?
