Depends which drill. Obviously when there's a bottom to the hole it needs to come up.

covers the various means quite well.
On the hole where they'd managed a pilot, the stuff fell out of the bottom and was moved by the miners - they still had a lot of space to play with, and I think possibly even machinery.
I understand that they had drilled several probe holes until they were discovered on the 17th day.
Presumably the mine managers knew which faces were active and would have known where the possible refuges were. As it is, one of the fortunate factors seems to be that the collapse occurred while the shift were on a meal break, so the team was all together in the same place.
Very quickly as I had this happen after a series of scans last year. On one of them the machine seemed like it was coming off its mountings and I thought summatt was wrong so we hit the switch!. As it happened it was alright, just hadn't had that particular type of scan before;!..
Mind you I suspect that if you wanted to get out quick you'd manage one way or the other;!..
Still fascinating to see a fMRI showing which bits of you brain are active whilst doing various things in an MRI machine, 'tho it makes me wonder seeing the bore size of these how they managed to do these tests;)...
Yes rather .. I have to have these from time to time and once I thought I'd be brave and dispense with the ear plugs;!..
Not a wise idea at all!...
Back to the original topic the MRI bore is about a bit bigger then that tunnel but by the time you've got them coils etc around your head then it does feel rather claustrophobic in there .. still when you see what these machines can do its all worthwhile:)...
I could have had a copy in the same way, but what I meant was that the doctor did not show it to me at the time, as happened with the MRI scan and angiogram.
