Stemming plugs create a tight seal in the blasthole, helping explosives work more efficiently. They can, combined with stemming, improve energy retention in the borehole, reduce airblast, and reduce stemming ejection so crews get safer, more consistent blast outcomes.

They help stabilize the stemming column, control gas release, and deliver more predictable fragmentation. This improves blast quality across open pit, underground, and quarry environments.

• Improve stemming retention/confinement
• Reduce airblast
• Support consistent fragmentation
• Help stabilize stemming in variable geology
• Increase safety across mining and quarry operations
• Can be used to create air decks in smaller diameter holes

Select a plug based on your borehole diameter, geology, and blasting objectives. This collection provides options suited for underground, open pit, construction blasting, and quarry operations — allowing your team to match the plug to your specific needs.

In open pit applications, ROCKRIVETS™ are typically used. In underground operations, ROCKRIVETS™ are typically used unless you don't need to support a lot of weight, then the MITIPLUG™ (Pilgrim Hat) can be used.

They are ideal for production blasting, perimeter control, presplit work, and general shot optimization. They help achieve cleaner benches, better wall control, and improved fragmentation.

Yes. These stemming plugs perform reliably in hard rock, soft rock, and mixed geology. They maintain a secure seal so your blast pattern remains consistent even in challenging ground.
