Kids football team could be stuck in cave for months

[Jarnhamar]

Pretty intense story.

12 boys and their coach decided to go exploring a cave in Thailand.  A flash rainstorm hit and blocked off the path out of the cave and it remains under water.

They were found after 9 days later by divers, stuck 3 kilometers inside the cave system (and 1km below the surface) on a little dirt mound.  Because of the high water lever and narrow passages, they may be stuck on that dirt mound for 4 months.

Get stuck or learn to scuba.I think the scuba option may be best.

A 2.5 kilometer swim in cramped space moving a meter every 5 mins or so is what they've been saying.  So about an 8 hour dive and none of these kids can swim.  There is no best option.

How was the 3mm/sec swim rate determined?  Is there a strong current flowing into the cave?

Not sure. Probably an estimate from the experts on the ground.

This article shows some of the challenges.  Experienced cave divers take three hours to get there.  Now add the fact that they might have to be tethered.  That might be the reason and I could see how it could significantly slow them down considering they can't swim or know how to dive at all.

Here's a local to Thailand site that gives a reasonable running description of the search operation with some interesting graphics of the cave system.  http://www.chiangmaicitylife.com/news/live-updates-teenager-football-team-trapped-thai-cave/

One option is to widen some of the tight spots with hydraulic chisels. Right now they have the kids and a method to resupply. Time to slow down and think the next stage through and consider a variety of options. I suspect many countries are offering up specialty equipment, resource and personal.

Dewatering is making another option possible- walking out. The rescuers claim to have pumped out 40% of the water.Maybe they could lower the water to use small boats ?

 

[Pusser]

I gather they're having difficulty pumping out the water fast enough and they're expecting massive amounts of rain, which will fill the caves up again.

One article that I read stated that the tunnel is so cramped in at least one area that tanks cannot be worn. That severely limits options.

Attempting to "widen", which would have to be both vertically and horizontally, has difficulties and risks - chiselling in such cramped quarters would be difficult to impossible, chiselled-off stone would have to be cleared out to have any benefit, and a cave-in would be lethal to rescuers and rescues.

Being stuck for a few months appears to be the least-sucky option, so far.

Bring in a mine rescue team.  That option should be examined, they may be able to drill a rescue shaft to them.

Read this on Wikipedia

Shaft sinking is one of the most difficult of all development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable.[2]

Historically mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve of mining contractors called sinkers.[3] Today shaft sinking contractors are concentrated in Canada, Germany and South Africa.

4 months on that little mound I'm guessing air would be a problem as well as sanitation.

Maybe Wainwright can send them all their shitter bags and we can shut down MR18 or MR19, you know to do our part.

 

[tomahawk6]

Air is being pumped to them today.

Having been in some gold mines you be surprised how little room there is when they are following a vein in a drift. As for the mucking out, labour is cheap there. You be amazed how fast they can tunnel. Other Miners would be following right along to brace the wider opening.

Thai's are very resourceful.

Like the quirky British volunteers who helped find them!

Like the quirky British volunteers who helped find them by taking just not enough rope...!

The boys seemed in pretty good spirits all things told!

But can they do it under water, which I understand is somewhat muddy, in the dark, while wearing breathing apparatus?

If they were chubby, basement dwelling, entitled, first world nation millennials then no... not a chance

I guess the rescuers are looking for a back way into the cave system.
