Canadian Survey Study – Buggy
CANADIAN SURVEY STUDY:
BUGGY
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 Buggy drill rigs.
Ryan Stimpson, Minnovare, Head of Engineering:“Average deviation at the toe across all 4 sites using the ‘Buggy’ type drill was 7.3% (1.2ft over a 16.6ft hole).
72% 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. (5.3% Standard Dev.)”
