"New Mechanical Excavation Systems for Hard Rock Tunneling"


***************************************
Abstract: 
While the tunneling industry has enjoyed the benefit of variety of machines for excavation of soft to medium strength rocks in conventional tunneling with roadheader for over half a century, excavation of hard rock in profiles other than circles that TBMs mine has remained somewhat of a challenge. Tunnel boring machines (TBM) have been successful in cutting hard rock, but they are not suitable for many tunneling applications since they only excavate circular shape tunnels, cannot make sharp angle turns to follow the vein or orebody, cannot cut right angle opening or change direction, and finally have a long trailing gear that follows them. There has been much efforts to develop machines to cut hard rock with non circular openings and this presentation covers these efforts and the recent advances and introduces related machines. These machines can work on variety of projects in tunneling and underground construction such as cross cuts, caverns, or short non-circular tunnels in hard rock for variety of construction needs.
