Apparatus and Method for Large Tunnel Excavation in Hard Rock
The patent application relates to a tunneling machine for producing large tunnels in rock by progressive detachment of the tunnel core by thermal melting a boundary kerf into the tunnel face and simultaneously forming an initial tunnel wall support by deflecting the molten materials against the tunnel walls. This provides, when solidified, a continuous linear. The heat required for such operations is supplied by a compact nuclear reactor.
