Current methods of stabilizing mine backfill involve the introduction of cementing agents, rock fragments or timber into the fill mass. The aim of this study is to examine the applicability of reinforced earth principles in mine backfilling.
Consideration is given to the identification of the functions and requirements of backfill. Various factors affecting the fill strength behaviour are Cited by: 7.
