I understand. I just wanted to make the point that it's not always so simple as it sounds - it could be something so expensive or slow to install as to make mining unprofitable and eliminate all the jobs, or some such. Or it could be sufficiently fragile that any mine disaster that it was useful in would also destroy the wireless installations (I'm assuming that the only way to make wireless work in the mines is basically to put in every few hundred feet a mini-wireless tower).
We'll see what the companies and gov't can come up with, hopefully there is a solution. It'd save a lot of rescuers lives if they could know for sure when people are alive and when they are not, when to take a risk and when not to and what the conditions are at the other end (at one mine disaster 11 rescuers were killed when they went in too fast).
I hope there's a solution, but it's never so easy as it seems - if it was easy, the mining companies would probably have implemented it in at least some mines, just for the cost savings in insurance and payouts to injured miners. The question is, is it merely difficult, or is it downright impossible (given profit margins, equipment effectiveness and durability).
