Keller drilling out a large diameter shaft at a mine in Queensland, Australia
#KellerGroup #Geotechnical #Engineering

[@mrman5517]

Likely final purpose: a ventilation shaft (wide diameter lowers air resistance and required air velocity for given volume), and probably a downcast shaft (slab does not seem large enough for fan infrastructure). The concrete piles and excavation shown are to overcome the first 50m of soft weathered ground you find everywhere in QLD (they also provide serious anchorage for vent control devices or blast doors later). Once this preliminary excavation is completed, and the collar is secureed a raisebore can be set up over the hole to complete the shaft to full depth. Normally this type of job would use a small excavator in the hole and a skip to hoist spoils, traditional ground support (shortcrete, bolts & mesh, cablebolts) can then be install by hand as the shaft progressively deepens (ie fast, cheap, and easy). However the OH&S in QLD prevents this kind of approach, so "no-entry" methods (as seen in the video) are used instead.

[@markyes2041]

Yes aussie OH & S is usually great but we still had fatalities in tunnel projects . That safety fence around the hole wouldnt pass muster with us since we had a site event where an 85 year old lady with dementia pushed her way through a security fence and started walking past open excavation pits , D10 Dozers , excavators and haul trucks before we grabbed her and escorted her back to the gate. . .

[@mikemcneil7327]

I've been watching tons of videos on a huge variety of topics, machinery, General things, and this is by far one of the most impressive ones I've seen in a long thine. Great job

[@TheOneWhoMightBe]

Imagine the torque that thing puts out!

[@dranoelarios4788]

TheOneWhoMightBe loaaads

[@CyraxCZ]

How much torque does it puts out?? ALL !

[@josephastier7421]

Then the saw binds up in the hole and the crane starts flying around in circles.

[@toddbaugh4193]

Need this at Oak Island!

[@gregpolachuk]

Saw this comment coming.

[@GetKruked]

They will need a big enough cason, otherwise the hole will collapse from the water.

[@UOttawaScotty]

I was just thinking the same thing

[@frane7588]

Why do you keep putting this same crap for background noise?

[@madeonearth3429]

Das ist weltklasse. Einfach wahnsinn. Solche techniken könnten auch porblemlos auf anderen objekten im all helfen, zB dem Mars.. Jetzt müsst ihr es nur noch umweltneutral zu machen! Lg

[@laughterman805]

That is the very straight, very round, very expensive hole

[@weldersandblaster]

VERY EXPENSIVE.

[@thepostman69]

You guys are way more careful drilling than we are in America. Not sure if it's the soil difference or what but drillers here punch 3-5 meter diameter holes 30 meters deep and just fill them with water and soda ash to hold the shape.

[@chouseification]

I'm not in the trade, but I was wondering the same thing myself - I've seen things along the lines of displacement drilling, filling the cavity with "mud" to hold the wall until the entire bore is filled with mud - then they build a slip wall or drop in some rebar and a form and pour from the top... That soil in QLD must be really really soft or something, since they reinforced that entire wall with the rebar columns before even starting to dig.

[@danotorioust2867]

Notice the Drill bit is constantly changed, they are just drilling pilot holes over and over they seem to hit a snag notice they stop using the large drill bit and use smaller ones to clean up the in side wall it would have been easier to use large bit to bottom,they seem to hit a few hard sections this is why they drill small to start and slowly step up size, also when ground water is filling up a drill hole this can cause collapses so fluid is mixed to increase the thickness of water making cuttings return easier and creating a stable wall inside drill hole, if no water is encountered you can drill if ground is stable like the video Drilling Clay and weathered rock (aged rock) if there were sand and gravel layers then they would require mud to stabilise the hole

[@Engineer9736]

The amount of employees leaning on that fence lol

[@FoxEarGaming]

They are there to make sure nothing goes wrong and to give information the the operator of the drill.. but yes there are allot of them just standing around.

[@bigredc222]

Having been on many construction sites, when there's something interesting happening everyone wants to check it out, I'd guess every person on the site looks in every time they pass by, I know I would.

[@couragewoodworks2843]

NightshadeGaming I think he is saying that because they are putting there weight on that fence directly next to a giant hole and if the fence failed they would fall

[@surveyingengineeringdesigninfo]

Amazing Working

[@timbramsen705]

awesome! Thanks

[@johntrueblue]

So it grinds a hole in the ground but how is it removing the ground soil from within the hole its creating?

[@jx8095]

How deep does the shaft go?

[@pilingdrill]

Good job👍

[@timpratten2258]

Michael Blackledge when you see them change to the smaller size head and move around the hole. It has a bottom on it which picks the dirt up. And ooens when moved awy from the hole.

[@GetKruked]

[@setaripantheon8801]

Is it collecting sand/material in the white pile shaft on the drill.....???

[@Turkentorque]

This was one unusual music video. Very educatianal tho.

[@beautifulsmall]

would love to see this used, couldnt find a vid that shows anything like this working

[@petea2721]

I'm going to dig me a hole, gona put a nerd in it

[@Unmannedair]

Cool technique, but it seems to have some rather severe limitations on how deep and fast the drill can go.

[@dmd8552]

That doesn't really matter as long as it can do the jobs it's hired to do cheaper, better or faster than other equipment.

[@setaripantheon8801]

Agreed I see very many limitations with this... First of all the digging material seems to be in the white pole and not contiusly emptied..

[@tlsigns3370]

This is called bored piers with soldier piles as a retention, the spoil is collected at the toe with the smaller diameter bucket (see the moxy taking spoil away), once depth is reached the remaining spoil is fed by an excavator in a bin with a crane till B.E.L is reached.

[@handlebaraddict]

great footage combined with a bumpin track. please can you tell mw ehat the remix is? Ive foind a few versions of the original but not this one. amazing

[@corsakias]

How many days for main hole?

[@gianniorlati9275]

Clamshell telescopic excavator on top and small excavator inside the shaft may be a cheaper solution, I guess, unless additional technical information on the shaft's features are provided ...

[@MaxwellPSmart]

Those people from down under know a thing about continuing down under

Nobody I probably revealed my age. 😛

[@counterfit5]

Nobody Jimmy Hoffa was the head of the Teamsters union in the US. He disappeared in the 70s and has never been found. Rumors and speculation put him in many places. Mythbusters even scanned a football field with an ultrasound machine to find him.

[@matthewnorman7507]

i could use twelve of these spaced evenly, set up just inside the perimeter of a large circle.... but then i would have to plum all of them to be exactly parallel with each other, compensating for the curvature of the earth and everything else.....

[@matthewnorman7507]

no.. it is a method of creating a space elevator using parallel particle beams as the tether that the platform travels up and down...

[@thedave7760]

Yeah go on Mathew. If that's all you need to build space tether then these guys can do it for you I'm sure. Call Elon I'm sure he will be happy to pay for it once he gets the hyperloop built.

[@Dockhead]

what you been smoking

[@matthewnorman7507]

the tether so to speak, is not really there.. the beams emitted, carrying a compressed magnetic flux, are for the purpose of keeping the platform centered and steady as it travels up or down between the parallel beams. the big holes are to house the beam emitters... if it functions as i have desired to design it, it will be usable at any latitude and not have to be restricted to the equator.

[@thedave7760]

You sound like a real genius, please call Elon.
