The mine is located in Sabinas in the northern state of Coahuila.

"We are at 97% of water extraction, so we already have all the conditions to go down today," said the national coordinator of Civil Protection, Laura Velázquez.

Although the authorities had tried to carry out the rescue on Wednesday or Thursday, they were faced with a water level problem at the site that caused a landslide on August 3 and flooding occurred, collapsing a wall of the adjoining abandoned mine.

"In order to be able to enter, remove the debris and start the search and rescue, it was necessary to have adequate water levels that would not put the rescuers at risk," said Velázquez in a video conference at the National Palace.

Currently, more than 600 members of the Armed Forces and civilians are in the area of the event and have extracted water with an average of 300 liters per second.

This collapse has sparked controversy in Mexico due to the actions of mining companies in the coal region, where more than 100 deaths of workers in the sector have been recorded.
