Mechanical and Aerospace Engineering Faculty Research & Creative Works

A simple analytical procedure that applies classical beam-column theory for evaluating passive rock bolt roof reinforcement is presented in this paper. The analytical model is derived from first principles and is capable modelling any number of reinforcing bolts. Each rock bolt is modelled as a linear spring and the model allows for non-uniform bolt spacing. In this study the rock beam is assumed to be isotropic and linearly elastic for the sake of simplicity. However, the analytical model can be extended to include anisotropic rock mass as well as inelastic material behavior. The solution to the couped set of governing …
