Could someone please explain to me why there is no communication method for communicating with the men without drilling a hole? Surely there must be some technology.....
Its that solid rock. Just too dense to let anything through. I think every deep mine should have a couple of communication holes drilled every so often. Just awide enough for a wire.
Watching the ISS this week, I’ve wondered the same thing. We can communicate with spacecraft and vessels beneath the ocean, so why not for miners?
You would think-------!!
Yeah, there probably is - but it would cost money.
My understanding is that this mine owner had been cited for over 300 violations of safety codes in the last couple of inspections, and had made little to no effort to fix the problems (I have no idea if the safety problems in the citations is related in any way to the current emergency). But obviously, the owner isn't too concerned with safety or spending money on some sort of communication technology for such an emergency...
I’ve thought about this and have concluded its just very hard to communicate underground.
In cave-ins wires get severed. Radio doesn’t work well under ground, light beacons don’t penetrate rock.
On the surface, under water, or in space there are lots of options. Not so easy down below.
Yes....why don't they have GPS systems on them when they enter these caves???
Actually there is undergound radio
