Robbins Tunnel Boring Machine Cutter Head at Redpath Deilmann

Full-face tunnel machine, drill head diameter 6 meters, last job: driving on the EBV Westfalen mine
A tunnel boring machine (TBM), also known as a mole, is a machine used to excavate tunnels. It is particularly suitable for hard rock. Such continuously working large machines are also used in tunnel construction in loose rock, which is unsuitable for tunneling using conventional blasting.

Full tunnel boring machine (TVSM) from the renowned Robbins Company from Ohio. This machine is equipped with a relatively small 6 m drill head and was good for domestic coal mining. Incidentally, the Robbins Company built the world's largest hard rock tunnel boring machine with a diameter of 14.4 m for the Robert Moses Niagara power plant? Most recently, this 6 m Robbins was used in the EBV's Westfalen mine in Ahlen. A "Robbins machine" was also used successfully in the 1980s to drive the Min. Stein mine. Today, full tunnel boring machines in hard rock are more in demand than ever. I don't think there is anything more to say about this "Robbins" because the drill head is specific and does not require any further details, especially since it may confuse the community.Personal comments do not constitute a TIP 😉However, I think it is important that if information or texts are taken from other sources, it is imperative to name the relevant sources.Plagiarism is not a minor offense!

Tunnel drill oh man 👎👎This is the head of a VSM.
For laypeople
Full-face machine that was used, among other things, in hard coal mining for driving roads
