How Tunnel Boring Machines Work - Howard Fensterman
2021-3-14 For the TBM, the cutting head is located at the very front of the machine. As the boring machine’s cutter-head rotates, it breaks through the rock and/or soil at a rate of 2.7 revolutions per minute and at a pace of about 50 feet per day. The machine looks like a giant worm, expanding about 272 feet in length.
