I used to work full time for a well trained rescue organisation, that included confined space rescue. (Not the fire brigade)
Mbasko and Goldierocks have done you all a service with this info. Old mines are deadly. All of the gases mentioned exist in most old mine workings, with the concentrations varying, Pockets of gas can move around the mine with the changes in temperature and slight air movement. So as in some caves one spot that was ok may not be ok the next time entered. Many gases are not detectable by smell, and within 30 secs you could be unconscious. Ground movement can make the old workings unstable, earthquakes, and pressure changes over the years takes its toll on the original tunnelling. I have seen posted on forums pictures of people risking their lives with little to no equipment, standing on 100 year old beams with a pit underneath them. May as well play Russian roulette with a loaded gun. If there was still a lot of gold in these mines, do you think the old timers would have left it? Is your life worth more than a few ounces of gold? Unless you might be a few yards from the entrance with fully equipped backup personal standing by if something goes wrong, it may not be a rescue, but a body recovery. I have had to do a few of those over the years, in industrial and domestic situations.
