Tunnel Excavation with Electrically Generated Shock Waves
The patent relates to an apparatus and method for excavating tunnels with electrically generated shock waves. The tunneling apparatus is comprised of a rotatable barrel for cutting a peripheral ring about a core and a bit which simultaneously bores a hole in the center of the core. The drive for the rock bit also contains electrodes which are pulsed to produce shock waves in the core to peel off a desired thickness of rock layer.
