Question

1. In underground mining, a mine drift usually undergoes some deformation, which may cause stability problems to the drift if the ground is not supported properly.

a) What is the main objective of providing ground support for stress induced deformation?

b) Discuss the interaction between the rockmass and ground support in terms of stress and deformation.

c) List the following commonly used ground support systems and their applications: mechanical bolt, grouted bolt, frictional bolt, cable bolt, shotcrete/wire mech. Pay attention to their behavior under in situ loading conditions.
