Australian Survey Study

Australian Survey Study: Drill set up process, not rig type, the primary cause of poor drilling.
Down-hole surveys were conducted across 17 Australian underground hard rock operations. The results have been analysed
to better understand typical drilling accuracy and the factors that result in blast-hole deviation. The data was further broken down by drill type (Boom, Horse-Shoe).
The findings of the study reveal that there exists a significant opportunity for a step-change improvement in drilling accuracy and stope performance – by reducing alignment error.
