CANADIAN SURVEY STUDY:
CUBEX
Down-hole surveys were conducted across 10 Canadian underground hard rock operations. The results have been analyzed 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, Buggy, Cubex).
In this case study, we will be focusing on the results from the Cubex drill rigs.
Ryan Stimpson, Head of Engineering, Minnovare: “Average deviation at the toe across all 4 sites using the ‘Cubex’ type drill was 7.4% (2.6ft over a 36ft hole).
61% of the error at the toe was due to alignment error – indicating current drill setup processes are not only inaccurate, they are also highly inconsistent (9.4% Standard Dev.)”
