As the first contractor in the world to mine hard rock with a 30-foot diameter Tunnel Boring Machine (TBM), Kenny has highly automated the entire tunneling process, reducing tunneling costs. In predominantly urban applications, tunnel boring is a quick, safe and cost-effective alternative to laying surface rails and roads.
Lowering the assembly for the tunnel boring machine (TBM) and the concrete liner that would be placed in the tunnel required some ingenuity, said Niels Kofoed, tunnel manager. "The deepest shaft most of us had been dealing with was maybe 100 or 150 feet for assembling a TBM, so doing the same thing through a 900-foot shaft was certainly one ...

Each machine operates as a self-contained underground factory, which as well as digging the tunnel, will also line it with concrete wall segments and grout them into place as it moves forward at a speed of around 15 metres a day. A crew of 17 people will operate each TBM, working in shifts to keep the machines running 24/7.
A tunnel boring machine (TBM), also known as mole, is employed for the construction of tunnels in hard or soft rock strata. The cutting process utilizes the rotation of the cutterhead (geared with disc cutters) and the blade pressure for excavation on the face of rock. Mostly, gripper and shield TBMs are ideal for tunneling in difficult rock ...
