This paper presents a 2D modelling study of a cemented paste backfill in an underground stope. A sensitivity study was undertaken to identify how the model behaved as different input parameters were changed over time. The paper chronicles the adjustments that were made to the input parameters in order to match situ pressure measurements from 1 set of instruments in the stope. The input parameters from the 2D model that best matched the measured results were then used in a 3D model. These model results were then compared to the other stope instrumentation results to check how useful the parameter modification was.
