Liner Pressures using Tendon-Based Support
The ground support functionality in StopeX can be tendon-based or surface support.
For Tendon-based support an equivalent active pressure being applied to excavation boundaries to provide equivalent resisting forces. We propose using the estimates provided by Hoek (attached) for support pressures:
Where:
Capacity_n is the support capacity for bolt system n at failure, yield or slip;
Ring_1 is the ring spacing of tendon system n; and
Bolt_1 is the bolt spacing of tendon system n.
The elastic stiffness is calculated using this equation:
Where:
Liner Pressures using Surface Support
For surface support, the maximum support pressure and elastic stiffness are calculated using these equations:
Where:
