The pipe roof support method is one of the pre-support concepts that nowadays is much used in conventional tunneling and has even been included in TBM support systems. This method of supporting potentially unstable ground ahead of the face provides a high degree of flexibility and can be easily adapted to the encountered conditions.Cited by 9Publish Year 2006Author Günther M.
