1 Introduction It is generally accepted that during hard rock tunnel boring machine (TBM) excavation, a cutter first creates a crushed zone at the cutterrock interface and the stresses from the thrust of the cutter are transmitted through this crushed zone into the adjacent undamaged rock (Snowdon et al, 1982, Bruland, 1998, Cigla et al, 2001, Zhang, 2001, Rostami et al, 2002)Tunnel Boring Machines [TBMs] are used for large bore, rapid tunnel excavation TBMs typically have a circular cross section between 1 m and 8 m and can bore through a variety of soil and rock strata The cutter head typically rotates at between 1 and 15 rpm, depending on the TBM diameter and the rockTunnel Boring Machine [TBM] technology in hard rock mining

Tunnel Wikipedia
A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal1 Introduction Ever since Tunnel Boring Machines (TBM) were introduced in 1950s, design engineers and contractors have been preoccupied with the question of accurately estimating machine performance for a given project settingPerformance prediction of hard rock Tunnel Boring Machines
