: Continuous operation of bulk mining is dependent on the stability of the fill that provides proper support of the ground. Cement stabilized fills with proper mixture can provide the required ground control necessary to mine the massive ore. When recovering are adjacent to existing mined-out space (i.e. stope), the stability of the ground for long-hole stoping will be governed by the stability of free standing vertical fill as well as the width/height ratio of that fill. The width/height ratio of the fill becomes too small with inadequate fill strength, and the stability of the free standing vertical fill may fail, causing delay of a mining operation and risking human life. The objective of this study was to evaluate the stability of the freestanding vertical face of fill.
