Shaft Boring Roadheader (SBR)

Quick and safe construction of blind shafts down to a depth of 1,000 meters.
The Shaft Boring Roadheader (SBR) was developed for the mechanized sinking of blind shafts in soft to medium-hard rock with up to 120 MPa. For the efficient excavation of the rock, the SBR has been equipped with a roadheader boom and a rotating cutting drum. This allows the creation of variable shaft diameters between 7 and 12 meters.

A lot different from when I worked on the Yorkshire Selby project! We spent most of our time on the shaft bottom drilling and firing and mucking out. We also used ready-mixed concrete instead of a gunnite process.

Still lots of that going on this is soft rock on these potash projects in Saskatchewan. If they were in Northern Manitoba, Ontario, or heaven forbid Quebec then its all hard rock likely granite.

As anex coal miner, brilliant

Amazing💯

[@willowitsapololife3674]

is it dangerous working in there?

[@HerrenknechtAG]

Thanks for your question. The Shaft Boring Roadheader (SBR) is safely controlled from higher working decks. In contrast to conventional shaft excavation, there are no personnel at the bottom of the shaft during mechanized excavation with the SBR. Overall, the SBR design sets new standards in safety for personnel. Best regards. Herrenknecht AG

BUCKET !!! In Canada we call 'the round things' we put the muck in, "THE BUCKET". Kibble is what we feed our dogs. Google it.
