Is there any technology on the market that would allow coal miners that are up to 1,800 ft below the surface to communicate with persons above ground? 1800 feet = 0.3409091 miles.

Jessica, I'm so very sorry about your dad. My prayers are with the men trapped in the Utah mine.
I was hoping that for safety reasons, coal miners would be required to carry with them a communications device so that they could talk with people above ground if there was an emergency. But I don't know if there is a 2-way radio that would transmit from deep in a mine to above the ground. I saw the phones in a mine on the news, but when there is a collapse or other problems, the men can't always reach a phone. I just think there needs to be something other than a phone to communicate with.
