One puzzle about the Chilean rescue

I asked my wife for a Chilean miner last night. She said, what's that? and i said, go down to the bottom of my shaft and stay there til christmas

Wrong!!


But funny

I don't understand why the miners are being hailed as "national heroes"? What exactly is heroic about sitting around underground for 69 days until someone else digs you out?

Not sure I would like to be trapped underground for 17 days without any contact from above, and assuming I was going to die for each and every hour that I was down there for that length of time. Just think about it..

Truly awful.

Magnificent achievement to get them out - truly uplifting.

Why was the hole on a slight incline?

Reduce the weight on the cable/pulley?

[The Hypno-Toad]

Thatcher sick + large deep hole in the ground going free = coincidence????

Why did they drill a shaft when all the graphics on The Sun Newspapers show that all they needed to do was tootle down the ziz-zag mines and just remove the spoil of the cave in! Simples

Who was that on the grassy knoll???

[Saddle bum]

If they were all in a prepared rescue shelter designed for use in case their escape was blocked, why wasn't a shaft already drilled down to it in the first place?

Would have saved a lot of overtime.

Chile has had a hard time recently, With the earthquake and other thing's so this is at least something for them to celebrate .They are national hero's for bringing the country together ,whilst surviving the most horrible situation of being the only Humans to ever spend that much time recorded underground.

fk.

you know whats going to happen now?

that david blaine fker is going to try and beat that.

and its all going to be live on e4.

with 1 hr daily updates of how he's sat down on bbc/itv

700,000 tons of spoil so probably not quite so simples

Speed up the rescue - like when you fold the back seats down?

Ah, a miner detail

excellent. I'll lean over next time I get on the scales then.

Pop him down the hole. Pull the mic and camera feed and shove a recording to him on a loop. "They are loving it David, keep going" and plug the hole with reinforced concrete.

Split the forces into their components - force of gravity acts towards the centre of the earth. Put the capsule on a slope, there will be less force acting on the cable, with a component acting on the side of the shaft. This is fundamental physics.

You may lean all you like on the scales and if you are a fat bd, you will still be a fat bd. However, your post makes you appear a bit dumb to me! No offence meant.

oh dear.

only the top section of the shaft is inclined - roughly 100m. from then on in it is vertical so the winch sheave takes all the weight anyway. plus the incline is only 11degrees off vertical which would make fk all difference.

additionally, the capsule only weighs 450kg, the rope alone will weigh more than that which will be solely supported by the sheave. all up weight will prob only be a couple of ton, whereas a mining hopper in a vertical shaft will be 100t. where is the logic for an inclined shaft with such a tiny weight and a 700hp winch?

vertical inclined shafts are just a method of drilling. there may have been geological instabilities they wanted to avoid. i'd be more concerned about the rope condition after 24hrs of rubbing at the point it turned vertical.

this is fundamental engineering. no offence, but i think i know a bit more about it than you do chunky

I note the escape capsule was built by the Chilean navy. Would it by any chance be similar to what they use for poking about inside the torpedo tubes of submarines?

Hey - lean all you like on your scales - it'll make f all difference to your weight (unless you are leaning on SOMETHING).

Was only putiing forward a reason why the shaft was inclined - and it certainly was at the bottom (see the angle of the capsule).

There may have been geological reasons for the route the capsule took - however, this was not what you were discussing in you post, which was an irrelevance.



Anyhoo - happy that you are convinced tht you are right with all of your engineering know how and what not - I'll just bow to your superior knowledge. Be happy - I can't be arsed myself!

p.s. You're still wrong about the scales crap.

anyone hear a whoosh?

Not hearing any whoosh - and its been a long time since I went to school - and in fact university - you condescending tosser.

If you wanted to make a meaningful contribution to the thread, you should have imparted your immense knowledge of the drilling techniques and geological impedements which faced those carrying out the extraction of the miners, rather then making an off the cuff remark regarding weighing yourself!

I'll not descend any further in this thread - its really become rather ridiculous.

my remark was a play on the inclined seats gag. the reduction in weight would have been minimal at that incline, and nil at maximum payout of the rope.

don't take everything so seriously.
