This thesis explores the possibility of using both miniature reflection (MSR-IE) and Ultrasonic (PUNDIT) techniques for the appraisal of paste backfill. / The use of paste backfill is gaining popularity, however various technical, environmental and regulatory constraints complexify the study of its behaviour. There are various laboratory experiments available for the appraisal of this material; however the results do not necessarily correspond to its in-situ response. The main objective of this experimentation is to evaluate the quality of the fill by the study of its P-wave velocity, hence establish a relationship between the curing-time, strength and P-wave velocity of the material. This preliminary analysis in the field of mining demonstrates the possibility of finding an easy, reliable and cost effective in-situ method of appraising paste backfill. / Given the complexity of the research project, the work focuses on correlating the quality of the paste fill, with the MSR-IE and PUNDIT systems, in a laboratory environment. The results demonstrate the potential of the MSR-IE investigation on Paste backfill and the near future possibility of in-situ testing with this method.
