Design and implementation of cemented rockfill at the Ballarat Gold Project
conference contribution
posted on 2014-01-01, 00:00 authored by D Sainsbury, Bre-Anne SainsburyBre-Anne SainsburyCemented rockfill (CRF) has been implemented at the Ballarat Gold Project to allow pillarless recovery of the
narrow vein gold deposit. The stoping extraction strategy requires both vertical and horizontal CRF
exposures to remain stable and prevent excessive dilution.
This paper outlines a program of initial laboratory testing and numerical modelling to ensure safe and
efficient CRF exposure design. A novel numerical modelling approach has been developed to accurately
simulate the particulate nature of CRF material. The stability of CRF exposures have been determined by
conducting a series of three-dimensional numerical models that incorporate extraction, filling and the
exposure sequence of the CRF filled stopes.
