[00:10.10]Why is the rescue taking so long? [00:15.18]Six men have been trapped in a mine for seventeen hours. [00:21.12]If they are not brought to the surface soon they may lose their lives. [00:26.79]However, rescue operations are proving difficult. [00:31.65]If explosives are used, vibrations will cause the roof of the mine to collapse. [00:38.73]Rescue workers are therefore drilling a hole on the north side of the mine. [00:45.14]They intend to bring the men up in a special capsule. [00:50.09]If there had not been a hard layer of rock beneath the soil, [00:55.15]they would have completed the job in a few hours. [00:59.64]As it is, they have been drilling for 16 hours and they still have a long way to go. [01:08.62]Meanwhile, a microphone, which was lowered into the mine two hours ago, [01:15.18]has enabled the men to keep in touch with their closest relatives. [01:20.74]Though they are running out of food and drink, [01:24.18]the men are cheerful and confident that they will get out soon. [01:29.90]They have been told that rescue operations are progressing smoothly. [01:35.41]If they knew how difficult it was to drill through the hard rock, they would lose heart.
