The third miner has come up, the capsule has gone down for the 4th miner. I am watching from CNN on the TV.
I just wonder if these sort of rescue shafts can be incorporated into mines as a sort of escape hatch or would these shafts compromise the structure of the mine?
I also heard the mine where these miners are trapped has been mined for about 130 years and has been horribly over-mined and there is structural problems within the mine in which walls and ceilings can collapse at any moment. That's a scary thought. I hope the Chilean government sees this and moves to have the mine shut down permanently and sealed off for good.
