Novel hybrid tunnel boring methods, systems, and apparatuses are described. Example hybrid methods integrate (a) thermal processing, e.g., preconditioning and / or thermal spallation (which may be used as pre-treatment), and (b) mechanical processing while boring tunnels in rock and other formations.
