Keith McCord ReportingWe want to take you back to when the mine disaster happened.

As you may recall, a mine collapse at 2:48 a.m. Monday, August 6, trapped six miners in the Crandall Canyon Mine.

  • The following day, another bump temporarily shut down rescue efforts. Crews began drilling the first bore hole.
  • On Wednesday, August 8, rescue crews began adding wood and steel supports to the interior of the mine and a second, larger drill hole was begun.
  • The first drill hole two and a half inches in diameter reached the mine on August 9. There was no response to a listening device sent down the hole. And oxygen readings were low.
  • Two days later, the second drill hole reached the mine. Over the next two days, crews lowered a camera three times, finding survivable space, but no sign of the miners.
  • On Monday, August 13, a third drill hole was started into a different area of the mine.
  • That drill reached the mine on Wednesday, finding breathable air, but again, no sign of the miners. Vibrations were also detected inside the mine
  • That brings us to yesterday, when a fourth drill hole was begun over the area where that sound came from. Then, at 6:35 last night, a seismic "bump" caused a second mine collapse.

Nine miners were injured, and three died from those injuries.
