For over 30 years R Duncan Pty Ltd has been manufacturing cylindrical clay stemming plugs using high quality inert clay. The clay used allows the plug to remain in it true form, but is also pliable making them easy and efficient to use. The plugs are widely used in underground mines to stem blastholes.
The plug requires no additional support materials when used and will in turn minimise damage to cords. The use of clay stemming gives maximum compaction and containment of fly rock. We supply our clay stemming plugs to underground mines throughout Australia
Our clay stemming comes in two standard sizes:
- 29mm x 200mm; and
- 32mm x 200mm
We can also produce 25mm x 200mm on request.
