Chile mine disaster ended with Chinese crane
proction method:
you can use the command box to make
use the destroy mode of fill
of course, you can also use red stone, which is very troublesome and slow
The Rescue Department mobilized 7 sets of equipment to excavate the collapsed mine and strive to establish contact with the trapped miners.

Chilean mining minister Laurence gobone said that the task of Chilean engineers assembling powerful drilling machines has been completed, and the next step is to excavate escape routes< According to the previous calculation, the vertical depth of the refuge shaft is 702m. The drilling will be carried out in two steps: first, a probe hole with a diameter of 10 cm will be opened, and then the lifesaving passage with a diameter of 66 cm will be expanded. It is estimated that 20 meters of excavation will be carried out every day to reach the 33 miners trapped in the ground through the layers of earth and rock
17 days after the mine disaster, the rescue workers finally received a note confirming the survival of 33 people. However, e to the complex environment of the trapped miners, the rescue operation will take another three or four months, and the trapped miners may not see the light until the end of this year
