SAN JOSE MINE, Chile (AP) – A new video of 33 men trapped in a mine under Chile's Atacama Desert shows them sending greetings to their families, talking about how they are doing better since receiving food and breaking into tears as they talk about loved ones.

In the video released Sunday, the men are shirtless because of the heat in the mine and wearing what look like white surgical pants, special clothing sent down to help keep them dry.
Most are upbeat, expressing gratitude to their families and the rescuers for the support they are receiving via handwritten notes sent to them through three small bore holes. Authorities also send food, water, medicine and other goods to them through the three holes.
After drilling three small bore holes in recent weeks to create lines of communication with the miners and deliver basic food and medicine, Chile's state-owned Codelco mining company will begin boring a rescue hole Monday afternoon that will be wide enough to pull the men up through 2,300 feet (700 meters) of earth.
The first step will be to drill a “pilot hole” similar in size to the other three. Then much larger machine cutters will slowly grind through that hole, forcing crushed rock to fall down into the mine shaft area near the trapped men.
Failure to keep the bottom clear of debris could quickly plug the hole, delaying a rescue that officials say could take three to four months.
In all, the trapped miners will have to clear between 3,000 and 4,000 tons of rock, work that will require crews of about a half-dozen men working in shifts 24 hours a day.
The men have basic clearing equipment, such as wheel barrows and industrial-sized battery-powered sweepers, Sougarret said. The hole will likely end up several hundred yards (meters) from their living area in the mine's shelter, giving the men room to maneuver and store the rocks, he added.
Sougarret declined to estimate how long the work would take, saying it would depend on how each step went.
Once drilling begins, the team will have to decide whether to fit the wider hole with metal casing, often used to seal a hole and prevent collapses in the walls.
“We may not have to use it in this case because the rock is really high quality, really strong,” he said.
The latest video, in contrast to the first 45-minute video released by the government on Thursday, shows little of the men's surroundings. Instead, it appears meant as a video postcard for loved ones, as each of the 12 men who speak to the camera are given about 30 seconds to talk.
At one point, the camera pans to a larger group of men, and several animated, joking voices can be heard throughout the tape.
One unidentified man, who squints in the light shone on his face as do most of the miners, said he is thankful “for all your efforts out there.”
Another man shown says he is doing much better because of the food and water the miners have received.
The miners will have to aid in their own escape by clearing thousands of tons of rock that will fall as a rescue hole is drilled toward them.
“The miners are going to have to take out all that material as it falls,” Andres Sougarret, Codelco's head engineer on the operation, told The Associated Press Sunday in a phone interview.
