Raise Boring Rig (RBR)

The Raise Boring Rig (RBR) developed by Herrenknecht is designed for the construction of shafts in rock down to 2,000 meters in depth. Thanks to its compact design, it offers high flexibility even under space constraints and is therefore suitable for various applications in the mining industry. It has proven its worth with its modular design and its efficient center-free drive. Connection shafts for mining or penstocks for pump storage power plants can be constructed quickly and safely.

You guys and gals do awesome work. Kudos.

This is such a cool toy. I want one. I don't need it, but I want it.

Awesome engineering!

Very nice animation, thank you. And that is a VERY nice "bit of kit".

very nice technology

[@misterguts]

Hello, HerrenknechtAG, thank you for this video! Is this technology suitable, without the upward reaming operation, to reach geothermal resources beyond 3 km deep?

[@HerrenknechtAG]

Hello cbmira01yt, RBR is not the right technology for geothermal applications and depths above 2000m. Our Group Brand Herrenknecht Vertical, manufacturer of onshore and offshore drilling rigs and equipment, offers automated drilling technology enabling contractors and operators to explore deep energy deposits safe, fast and cost efficiently to depths of down to 8,000 meters.

WOW!!!

[@lecirconflex]

Out of curiosity: Could you explain the purpose of boring in an upwards direction? Why could the shaft in the video not have been bored from top to bottom? What requirements call for this?

[@secondarycontainment4727]

Thinking about it now - I did see another system that extracted from the surface side. But it used water as a transport sytem. Maybe the idea is that they can't use that because it would flood tunnels at the bottom?

[@michaelkarnerfors9545]

Note: I am just a layman speculating, but... The advantage is the ease in getting the bore waste out of the way. Instead of having to work _against_ gravity, lifting it out of the shaft, with the drill head in the way... you let gravity do the work for you, making the masses fall down onto a conveyor belt and then over to a lift.

[@secondarycontainment4727]

@@michaelkarnerfors9545 Seems right - getting the waste out of the pit seems to be the issue. As I stated before - the other systems I have seen use water to transport the waste up and out - these systems need filters/vortex systems to separate that (aggregate?) out of the water so that the water can be returned and re-used. If you don't have access to a water supply - I can see this and other system details as an issue (even routine maintenance of the filtration system).

​@@secondarycontainment4727 ​ @Michael Karnerfors Thank you for clarifying, this makes a lot of sense.

[@nbtpco.5906]

hello, what is the pulling force for La Croix ascent during the construction of the well in vertical ??? force in KN where Bar 🤔🤔🤔🤔

[@HerrenknechtAG]

Thanks for your question. The pulling force varies between 4,500kN and 22,000kN depending on the machine. Best regards. Herrenknecht AG

А крепление обечайки, всё слишком красиво,да по русски " забыли про овраги", вывозка породы под открытым очистным пространством? Где и как производится крепление обделки ствола

[@JM-ml3ch]

wheres all the mined material?

[@markyes2041]

it drops down on to a splitter shute which allows it to drop into apron feeders which in turn feed it to conveyors which drop it into 6x6 articulated dump trucks which take it to the surface.

[@srfrg9707]

I commented once that a video was boring. Now youtube suggests me that kind of videos. Artificial intelligence they call it... That's artificial stupidity.

[@zyxwvutsrqponmlkh]

Why does everything move so slow?

[@secondarycontainment4727]

Mostly because these things weigh hundreds of tons... quick means you're probably going to break something. Broken equipment costs money... by the second.

[@easternwoods4378]

Short of a missile silo I can't think of an application where you need a shaft that already has an access at he bottom

[@shane9873]

Mining, raise bores are used quite alot in mining, my site has 3 for ventilation and we are planning another 5 in a new project.
