Effect of Tunnel Shape and Support System SpringerLinkPrinciples of rockbolting design ScienceDirect

Stability level of tunnels that exist in an underground mine has a great influence on the safety production and economic performance of the mine Ensuring of stability for soft rock tunnels is an 1 Introduction Rockbolt is the most widely used support element in support systems in underground mines and civil tunnels Rockbolting design is indeed mainly based on experience and it appears that rockbolting design is simply a business of selection of rockbolt types and the determination of bolt length and spacing but one essentially
