Since Tuesday, the technical team in charge of the rescue no longer talks about times. "They are aware that it has been very painful to talk about hours and that deadlines have not been met. Especially for the family, "they explain from the surroundings.
For this reason and because perhaps that final four-meter stretch until reaching Julen "chopped" by hand by the miners is even more complicated to estimate, no one dares to venture when this last phase may begin. The hardness of the land does not add up. «Down there, so down, nobody has touched in millions of years. The particularity of the stone that we are finding is its hardness. There is a lot of phyllite and quartzite. The first one is something more clayey and the second more sandy but both are very hard, "explains one of the geologists involved in the technical advice. The expert assures that they have been speaking for hours with the miners of the Hunosa Mining Rescue Brigade, who would already be checking with different tools «if the rock starts well». It is important to know as much as possible the type of stone that you will find, especially to choose the best tool. The Asturian miners must choose the hammer that "best endure" the hardness of the rock. They will count, if necessary, with those controlled microexplosions that will be carried out by the mountain rescue experts of the Civil Guard. These tasks represent a "titanic" effort for these Asturians. That's why they think they'll go in pairs and take turns every 30 or 40 minutes. Lack of oxygen is another of the difficulties. They wear breathing equipment but, they explain, the same exhalation of the professional "heats up" the scarce space.
