This is only when specialized miners will be able to get off. in a metal cage to operate the connection with the well where the boy is.
This task may take "up to 24 hours", warned the engineer Ángel García Vidal, who heads the technical team.
This tunnel "will be done manually, with the help of the pick, if the ground is soft."
In addition to the tunnel boring machine, engineers and miners, there is also a team of explosive technicians from the Civil Guard urgently occupies, said a spokesman for the armed institute.
However, the advance was delayed because of the great hardness of the terrain. On Sunday, the teams discovered a five-meter layer of granite. And although the predictions for digging the parallel tunnel are 15 hours, they already have more than 40.
