I believe he meant pragmatic.
DarkspARKS,
While you have put together a post using words that compel one to believe it is coming from one of a fine formal education, it is obvious that such verbiage is awkward for you. In other words, I am unimpressed with fancy words when they do not fit the facts. Do not get me wrong, I believe in the proper choice of words when they give added detail or clarity, but not when used to only impress with no added benefit as to understanding. Personally I felt upon reading your post that you were trying to obfuscate the lack of facts in your opinion in order to defend your position.
Getting to the point. You can take whatever risks you want personally, that is your right. But when you post on this forum a procedure or process recommending it for others to follow, you will find that if others here feel you have erred in judgment we will give our opinions to the contrary. My previous comments as to your procedure were to not only to look out for “your” safety, but to caution others that may choose to follow in your footsteps.
Let us get back to what you said.

Honestly, I did not consider that very important factor in planning for this venture, which as someone who is OSHA 30 certified you would have thought would have remembered that! I mean really: just because I'm delving lower than the SULFIDE layer doesn't mean that sometime in that 100 year time frame water didn't seep in and create a hydrogen sulfide chamber - right?! :shock: Carbon Dioxide pit? :shock: Carbon Monoxide tomb? :shock:
Hydrogen sulfide http://en.wikipedia.org/wiki/Hydrogen_sulfide “Hydrogen sulfide is slightly heavier than air; a mixture of H2S and air is explosive”.
Carbon dioxide, http://en.wikipedia.org/wiki/Carbon_dioxide not a serious risk unless you wish to breath O2. But you may wish to consider its mining use “In enhanced coal bed methane recovery, carbon dioxide is pumped into the coal seam to displace methane”.
Carbon monoxide, http://en.wikipedia.org/wiki/Carbon_monoxide is slightly heavier than air (still air in a cave anyone) “During World War II, a gas mixture including carbon monoxide was used to keep motor vehicles running in parts of the world where gasoline and diesel fuel was scarce”. That sounds like it could possibly detonate.

1. Flammable gas is naturally heavier than air, and as such any flare up originating from that lower level would stay on that level.
Not true. You may get "just" a flare, but you may also get a detonation. Not a good thing even under normal circumstances, let alone in an old mine with you standing over the hole holding a rope. How many tons of rock do you think were over your head?
You had also mentioned a LPG gas explosion in your past (damn glad it did not kill or cripple you), since you were in the petrochemical refining industry you should obviously know where propane comes from. Propane itself in a refined state is heavier than air and very explosive. Some of its raw constituents are heavier than air as well, and very explosive.
Again, take whatever risks you wish. But if you put your methods forward on this forum as the best way to proceed, expect others to hold you to task if they disagree with your risk assessments.
My “personal” #1 priority here is to keep people safe. Helping people recover precious metals is secondary.
As always I welcome constructive criticism. I would also ask for your indulgence if I have been less than articulate in my reply due to my lack of a formal education.
