dc.description.abstract The aim of this project was to determine whether the introduction of short bolts into a stope hangingwall would increase the stability of the hangingwall beam. A simple physical 1/10th hangingwall model was constructed out of concrete, with properties scaled accordingly. The analytical theory behind the scaling procedure is outlined in this report. The hangingwall model was supported at either end, confined laterally, and loaded to destruction vertically. Simulated rockbolts were installed and a significant increase in the strength (4.6 times), stiffness (7.7 times) and energy absorbing capacity (2.5 times) was observed. The modelling procedure, setup and interpretation of results are discussed. en
