heal.abstract	Numerical modeling is widely used to perform numerical experiments, providing a quick and low-cost answer to many engineering problems. Therefore, numerical model setup and validation of the results with experimental data is of the utmost importance in providing such simulations with the required credibility. In this research, simulation of laboratory tested bolted rock beams is performed using two widely used joint failure criteria; Mohr-Coulomb and Barton-Bandis. The experiments that are simulated were performed in a centrifuge to study the mechanism of reinforcing bedded mine roof with pretensioned bolts. The dinstinct element method, in combination to the finite differences method is used to perform the numerical experiments. A good approximation of the experimental data is achieved, the best results having been provided by the Barton-Bandis joint simulation through calculation of instant cohesion and friction parameters. © 2012 Taylor & Francis Group, London.	en
