TL;DR: In this paper, the authors used combinations of support systems such as rockbolts, shotcrete, forepoles and yielding steel sets to control the stability of excavations in very weak rock associated with faults and shear zones.
Abstract: Controlling the stability of excavations in very weak rock associated with faults and shear zones requires the innovative use of combinations of support systems such as rockbolts, shotcrete, forepoles and, in some cases, yielding steel sets. Drainage and the sequence of excavation play critical roles in reducing the potential for failure. These approaches are illustrated by means of practical examples.
