Pink Collar-
Saver Cones

The Pink Collar-Saver Cones are used primarily to protect hole collars from collapsing, effectively resulting in a reduction of lost blastholes that require re-drills.

With the cones:

  • Holes are kept free from debris
  • Hole collars are kept intact
  • Downlines are secured
The Pink Collar-Saver Cones are available for blasthole diameters ranging between 3.5 inch (89mm) to 10 inch (251mm).

How does it work?

The Pink Collar-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.
Priming and charging is done through the installed cones. Once primed, the cones allow for the downline to be secured to prevent the possibility of falling into the hole. When the blast team is ready to stem, the cones are removed and stored for future use.

What are the benefits?

  • Keeps blasthole collars intact
  • Prevents blasthole collars from collapsing and blocking holes
  • Re-usable – cost of cones are amortized over a certain time period (take better care of the cones and they will last longer, reducing the total cost impact)
  • Reduces the number of re-drills as a result of collapsed hole collars, resulting in an improved blasting outcome and less costs on red-drills
  • Downlines are secured (no need to tie downlines to bags/sticks/rocks)

What started as an idea on our whiteboard towards the end of last year has grown into a range of products (pink ones!) as a result of the positive reception and value-add shown in the market.

Today we welcomed samples at the office from our first production on two new sizes (127mm and 203mm diameter).

So what do these bright and slightly funny-looking things do?

They give love and attention to blastholes by helping to protect the integrity of hole collars (the top part of a hole) to reduce the number of holes that need to be re-drilled as a result of collar collapses.

Treating drilled holes like short-term assets pays incredible rewards over the long-term. Taking care of holes results in the gap between design and actual becoming significantly less, which ultimately leads to improved blast outcomes and mining productivity.

Holes that have been drilled are generally seen as an expense. Giving them lots of love and attention and treating them like assets yields incredible returns.

Take care of your holes, and they will take care of you. These are our pink collar-saving cones that we developed to address the expensive challenge of collar collapses on blastholes. Less re-drills, less costs, better blasting outcomes!

Priming is the process of connecting the detonator to the booster and lowering it down into the blast hole.

Once holes have been primed, explosives can be pumped into the blast holes.

The combination of the detonator and booster serves the purpose of producing a mechanical shock that is sufficient to allow for the explosives to detonate.
