The subject is a basic geotechnical subject synthesizing the previously acquired knowledge in the field of rock dismantling, technology of stamping and reinforcing of underground works and other disciplines. In addition to the design of basic parameters, buildings (size and shape) deals mainly with the issue of tunnel and cave tunneling methods. There are presented classic tunneling procedures for tunnel excavation as well as model tunneling methods. Part of the subject is also the way of tunnel ventilation and isolation. Considerable attention is paid to machine tunneling in difficult natural conditions (shielding, extrusion, microtuneling, etc.).
