LIMITATIONS
The software is intended for the static design of rock reinforcement (cables and rockbolts) against estimated deadweight rock loads. It does not consider ground deformations or more complex loading mechanisms. Also, this design methodology does not consider surface support for the ground between rockbolts. This method was developed through experience in weak rock mass “hard rock” mines, at shallow to moderate depths. In the US it has been successfully implemented at depths less than 4000 ft below ground surface. The applicability of this design methodology outside these conditions has not been assessed. The user should consult available published surface support design methodologies for such guidance.
