They just need to pump water from a local brook into an aqueduct that outlets into the hole.

That's what I did to cap an open magma pipe in one of my forts.

I believe the massive fire is actually the result of an attempt to turn nuclear weapons into economically useful tools, either by fracturing rock trapping in natural gas, or attempting to extinguish a runaway well fire.

[Sarvesh Mossbeard]

The massive fire was done intentionally to burn away the methane.

I have actually read about that hole in some magazine and as I have quoted Sarvesh, it IS because of this.

[HAMMERMILL]

Yeah, methane is poisonous and a highly potent greenhouse gas, its also very clean burning.

So in some weird way, having a massive fire that never stops burning is ecologically better then the alternative.

Wait, so we could solve that greenhouse gas problem by sending it all to the Russians? sounds simple.

We send aerosol cans of CO₂ to Russia, then record the effects of ten thousand at a time being dumped on the fire, posting on YouTube.

And gygas.

Methaneīs about as toxic as nitrogen. At body temperature it will do absolutely nothing whatsoever. Itīs the explosive nature that makes it dangerous.

Methane by itself indeed is innocous, but I think that the mine gas probably has other components alongside. Sulphuric and nitrous stuff maybe? And even mercury.

Damp (mining)
From Wikipedia, the free encyclopediaJump to:navigation, search
Historically, gases (other than breathable air) in coal mines in Britain were collectively known as "damps". This comes from the Middle Low German word dampf (meaning "vapour"), and was in use by 1480 [1].

Damps included:

After damp, a mixture of gases (carbon monoxide, carbon dioxide, nitrogen and others) produced following explosions of firedamp or coal dust
Black damp, stythe or choke damp, a suffocating mixture of nitrogen and carbon dioxide[2]
Fire damp, any mixture of flammable gases, principally methane
Stink damp, usually hydrogen sulfide; toxic and explosive, but easily detectable by the smell
White damp, carbon monoxide, highly dangerous due to being both toxic and explosive

Carbon monoxide is explosive?  Although that's wikipedia, no one can ever be sure..

Read that line again, carefully.

I'm talking about that white damp line. Unless I'm terrbly confused

MSDS for Carbon Monoxide. Note that it has 4 out of 4 points for flammability. I'd say that if you get this in a decent mix with oxygen, then you'd better not have an ignition source nearby or you're in trouble. Explosion limits are usually quoted as "high" (one source quoted between 12.5vol% and 75vol% for the explosion limits), which means it won't reach explosion limits before you're dead. However, it could form an explosive mixture nearby, without you having real trouble with it and then go boom...
