Tunnel Construction Rocks with Boring Machines -

2020-10-13  The hard rock TBMs use mounted disc cutters that function by fracturing the rocks and chipping them off the tunnel. The resulting muck is then moved through the cutter head openings on the machine’s conveyors, subsequently removing them from the tunnel. Two types of hard rock TBMs are the shielded or open-type machines.
