OPEN STOPING

Open stoping can be simulated down to ring scale excavations steps, incorporating stope scale discontinuities. When this is done in a non-linear, large strain model, there is an opportunity to compare the model to the measurements of stope performance that matter for productivity and
recovery.

BE specialises in application of advanced, multi-scale, discontinuum modelling tools  to simulate open stope over break, access conditions, filling and induced seismicity. We are the only provider of probabilistic simulation for  stope overbreak  potential.

3D non-linear mine-scale submodel of open stoping simulation

Our open stoping tools incorporate:

• Large numbers of discontinuities as well as strain softening, dilatant rock behaviour
• Multi-scale representations of the rock and mining processes: the coupling of length scales from stope to  mine scale can be simulated
• Direct calibration: measured deformation and energy are directly compared to deformation and energy in the model
• Quantitative estimates of error and resolution—essential when making long term forecasts
• Rapid response to design changes, allowing integration into the mine planning process at every stage

The intent of BEs approach is to capture the mechanisms of stope problems  with the highest possible confidence, to enable a genuine Simulation Aided Engineering process for Open Stoping.
