    the roof support design. Moreover, the decision to rely solely on the permanent rock bolts as the primary support for a 100-year design life meant that the rock bolt design could not be undertaken using rudimentary modelling or empirical design approaches. Over 1000 modelling runs were conducted using various state-of-the-arts modelling ...
