>>2123261Please learn some basic safety info on underground mines. Stay out of coal mines in general, their death traps more than any other mine due to toxic atmosphere replacing gases and poor ground stability.
Next, in general watch for mines with poor or no air flow coming out of the portal, this means that air inside is likely stagnant. Watch for stagnant water as well, gases can be trapped in mud under the water and cause you to pass out later when you come back out. Watch for false floors over cavities or stopes, look out for failed supports etc.
In general just stay the fuck out of mines unless your trained to do it or work in them.
