They've drawn up a list suggesting which miners should come out first, next and last.
Navy Commander Renato Navarro tells The Associated Press that the list is based on daily examinations of their physical and mental health and strength of character during more than two months of captivity.
Navarro says the first one up should be capable of handling a frightening setback in the narrow shaft.
Next should come those with illnesses.
And the last to surface should be the strongest physically or in terms of their character.
