Integration of Instrumentation and Computer Modelling to Understand and therefore Better Design and Represent the Rock bolt Support Behaviour
MetadataShow full item record
A safe and efficient ground control system is one of the most vital components of an underground mine’s operations. Current rockbolt ground reinforcement design methods do not consider the actual in-situ behaviour of the rockbolt. Instrumented rock bolts can be used to understand the actual rockbolt response under different loading conditions. Work done in this thesis aims to integrate the actual in-situ response of rockbolt with improved numerical modelling procedures for designing better ground support.

Reinforcement selection for deep and high-stress tunnels at preliminary design stages using ground demand and support capacity approachMasoudi, R.; Sharifzadeh, Mostafa (2018)Underground mining is going to be deeper gradually because near surface resources are going to be depleted. Therefore, risk of seismic events in underground mines is escalating. Additionally, existence of the large ratio ...
