Abstract

Determination of the minimum required strength of backfill is the key design aspect for underground mining with backfill. In this study, a 3D simulation model was developed for predicting the required strength of backfill and displacement contours, yield state, and strength/stress ratios were considered to evaluate the stability and failure mechanism of backfill. The backfill design strength, assessed from numerical modelling, was compared with the previously developed analytical solutions. Further, the developed 3D simulation model was successfully used for backfill strength estimation of a few underground stopes in Eastern and Western India.
