The Hole-Saver cones are used to reduce the number of lost blastholes as a result of collar collapses, water ingress and debris blockages.
With the cones:
The Hole-Saver Cones are used throughout blast block preparation. Once blastholes are drilled, the cones are inserted into the holes to maintain hole collar integrity and to keep debris out.
Before priming and charging, the blasthole-saving cone is removed temporarily, and re-inserted once priming and charging has been completed.
The cone is then left in the hole, preventing any debris or collar collapses before stemming takes place. When the blast team is ready to stem, the cones are removed and stored for future use.
