Abstract

Research in this article presents development of model of strata interaction with roof support installed in bauxite. The main task of this research is modelling of rock degradation over the surface of underground roadway and its impact on the loading of rockbolts. Results of such analysis can be used for planning appropriate measures for the prevention of rock degradation or installation of additional support. The numerical model is based on the finite element method, using Phase2 software.

Keywords: rock properties, roadways, rockbolting structure, roof support
