Prevent blast holes from becoming blocked by casing them with Slotted Poly immediately after they are drilled. Avoid wasting valuable time and resources cleaning out blocked holes.
- Currently used with great success at a number of underground mines in Australia.
- Proven to reduce hole clean-outs during stope prepping
- Slotted design allows emulsion to expand through the slots during gassing, minimizing the de-coupling of the explosive
- Can be installed and secured in the backs from ground level immediately after drilling with the aid of a ‘POLY SPIDER’
