ABSTRACT: Following a brief review on the currently widely used numerical approaches in mining geomechanics study, rock mass parameters along with stress characters that significantly affect modelling results are analysed through examples using different numerical methods. The sensitivity of mining geomechanics modelling results to input parameters and applied rock mass failure criteria are tested through different numerical approaches both 2D and 3D. A comparison is also made of numerical modelling between using rock mass parameters as input with empirical failure criteria in continuum modelling methods and discontinuum modelling methods that mimics the behaviour of both intact rock and rock mass discontinuities. Some cautions are raised in order to correctly use and interpret mining geomechanics modelling results in mining practice.
