[00:20.51]Six men have been trapped in a mine for seventeen hours. [00:26.70]If they are not brought to the surface soon they may lose their lives. [00:32.41]However, rescue operations are proving difficult. [00:36.78]If explosives are used, vibrations will cause the roof of the mine to collapse. [00:44.14]Rescue workers are therefore drilling a hole on the north side of the mine. [00:50.92]They intend to bring the men up in a special capsule. [00:56.43]If there had not been a hard layer of rock beneath the soil, [01:00.96]they would have completed the job in a few hours. [01:05.00]As it is, they have been drilling for 16 hours and they still have a long way to go. [01:12.85]Meanwhile, a microphone, which was lowered into the mine two hours ago, [01:18.99]has enabled the men to keep in touch with their closest relatives. [01:24.13]Though they are running out of food and drink, [01:27.36]the men are cheerful and confident that they will get out soon. [01:32.25]They have been told that rescue operations are progressing smoothly. [01:37.62]If they knew how difficult it was to drill through the hard rock, they would lose heart.
