Paper presented at the 12th ISRM Congress, October 16–21, 2011
Paper Number: ISRM-12CONGRESS-2011-220
... the rock dilates, the smooth bar sections between anchors elongate plastically to accommodate the rock deformation and thus absorb deformation energies. The dynamic performance of the bolt was studied through laboratory drop tests. The tests were carried out by applying impact load to a bolt section...

... ABSTRACT The only feasible method for dealing with extremely squeezing ground is providing sufficient space for accomodating rock deformations and installing a so-called yielding support, i.e. a support which can deform considerably without damage. This paper provides a critical overview...

... in the roof and walls. Figure 2 shows a shear failure in the wall of a deeply- located opening. Shear failure in weak rock more than often leads to large rock deformations in the near field of the open- ing, Figure 3. It is not unusual that the convergence of a 6- m wide tunnel reaches 0.1 0.3 m. For the case...
