When our guide came we climbed the rest of the stairs and waited for the elevator to take us down into the mine. As we got off the elevator we seen coal bins full of coal. The bins were dumping the coal onto a conveyor belt that took the coal up to the surface.
We learned about how they use to use canaries to detect methane. Today they use a davy lamps (which have a flame) or computerized monitors to detect methane. Most of the world still use davy lamps because it's cheaper then the computerized monitors.
Using a device such as a davy lamp increase the chances of a fire starting. If you catch on fire while IN a coal mine you MUST NOT stop, drop, and roll. Doing so will start the whole place on fire, because it's a coal mine. The coal miner explained that if a miner does catch on fire that they have to "take it like a man" and walk up to 2 miles or more to the nearest water pit and jump in!
After the coal miner explained how these things worked he told us to plug our ears! After our ears were plugged the machines were turned on! They were loud!! The coal miner explained that because of the noise levels of these machines many miner end up deaf in a few short years. I believe it after hearing those machines go!
There was a door way that said Miner Only! We wanted to go back in there and see what the miners where up too, because we could hear them talking. However we were not allowed in because we were not miners!
The coal miner explained how this machine works before turning it on. It was NOT as loud as the previous machines, but I don't think it is healthy to be near that much noise all the time. I was amazed to learn that once it got to the end they would just leave it and go get a new machine. New machines are not cheap! They cost MILLIONS of dollars!
