A New Criterion for Numerical Modelling of Hangingwall ...

2020-7-4  In the case of numerical modelling, some of the available criteria used to evaluate hangingwall overbreak do not include the intermediate principal stress around the stope and/or the rock mass geotechnical characteristics. In this study, a new criterion for numerical modelling is proposed to estimate the hangingwall overbreak in open stopes.

Extending empirical evidence through numerical

2021-5-21  Numerical models, on the other hand, are built upon the mechanics of materials and can be used to conduct experiments in which unknown situations are studied. However, numerical models need to be grounded in reality, which can be achieved only through calibration and vvalidation against empirical evidence. The synergy between empirical and numerical
