MITIPLUG
MITIPLUG™ is a mechanical plugging device used in underground mining to prevent emulsions and ANFO from slumping or falling out from up holes. The device is made from a semi rigid polymer. The product is resistant to the chemicals in emulsions and ANFO. This plug was recently improved and now features a higher holding capacity, improved downline protection as well as a better seating mechanism for the ANFO hose.

Why MITIPLUG
Blocks emulsions, ANFO
Holds back both emulsion and ANFO in upholes and angled holes.
Why it matters: One plug type handles both explosive products. Simpler inventory, no product-specific plugs.
Chemical-resistant polymer
Made from polymer that won't degrade on contact with explosive chemicals.
Why it matters: Maintains its seal and strength throughout the sleep time. No softening or failure from chemical attack.
High holding capacity
Deep fin design provides exceptional grip force against the hole wall.
Why it matters: Holds heavy explosive columns in steep upholes without slipping.
Improved downline protection
Fin arrangement shields detonating cord and shock tube from damage during loading.
Why it matters: Your initiation system stays intact. No crushed or severed lines at the plug point.
Flexible fin design
Fins flex to accommodate slight variations in hole diameter.
Why it matters: Works in holes that aren't perfectly round. Real-world drill holes, real-world performance.
Enhanced seating mechanism
Tapered entry guides the plug into position and locks it at depth.
Why it matters: Seats cleanly the first time. No re-insertions, no adjustments needed.
Built for the bench.
Drop it in. It holds.
Flexible fins fold back going in, snap open at depth. The plug stays where you placed it.
Chemical-resistant polymer
Built for direct contact with emulsions and ANFO. Won't degrade in the loading environment.
Improved downline protection
Updated seating mechanism protects the detonator downline during loading and right up to firing.
Built for every condition.
Underground upholes
Prevents emulsion or ANFO slumping out of upholes. Hold the collar height where you set it.
Voids and breakthroughs
Bridges voids in the column and seals breakthroughs that would otherwise waste explosive.
Cost-sensitive headings
Cheap insurance against wasted emulsion. Pays for itself in unblown product.

Pick BLASTBAG™ SOLO when you're running surface benches and want the most-used aerosol gas bag on the market. Self-contained, single-operator deploy, no extra gear — ~30 seconds per hole. Two-speed actuator lets you inflate slow or fast depending on the situation. Sizes from 4.5" to 12.25" (114 – 311 mm) cover every standard production hole. Class 9 DG — stores and ships under aerosol rules.
Pick BLASTBAG™ EVO when you want aerosol convenience without the SKU sprawl. Two sizes — Hawk (4" – 6") and Eagle (6" – 9⅞") — cover most surface holes, so you stock less and make one decision on the bench instead of four. Single bladder seals against the hole wall; pressure sleeve controls inflation speed. Class 9 DG.
Pick BLASTBAG™ ACE II when storage or transport rules make aerosol products a hassle, or when you're running metal-detector conveyors that throw false trips. Chemical reaction inflation — no aerosol, no metal components, non-DG. Same air-deck performance as SOLO and EVO, just delivered through a controlled chemical reaction instead of pressurized gas. Sizes 3" through 10⅝" (76 – 270 mm).
Pick BLASTBAG™ AERO when you're underground with service air lines available. Compressed-air operated, dual-bladder construction, snap-on coupling for fast connect/disconnect. Works in any direction — up holes, down holes, even underwater. Sizes 2.5" through 12.25" (64 – 311 mm). Best-seller in underground and the cleanest install when air is already on site. Non-DG.
Pick BLASTBALL™ when the hole is wet or you've got breakthroughs and cracks to seal. The only inflatable in this collection rated for wet-hole deployment — lower it through water on a drop line, then inflate with compressed air. Reinforced rubber bladder with nylon webbing handles -58°F to 185°F (-50°C to 85°C). Sizes 2.5" to 8" (64 – 203 mm). Underground development specialist.
Pick MITIPLUG™ when you're loading emulsion or ANFO into underground upholes and need a mechanical plug that creates an air deck AND retains the column. Flexible pilgrim-hat fins fold back on insertion, then lock in place — and the fins let gas through. Revised design includes downline protection. Fits 2.5" to 4" (64 – 102 mm). The most popular plug for underground emulsion upholes.
Pick ROCKRIVET™ when you need to create a controlled air deck on a trim or pre-split row, or hold the charge column with maximum retention and downline pass-through. Collet-style fins bite the hole wall and don't walk, twist, or shift. Iron ore case study: 38% smaller P80 fragment size with ROCKRIVETS installed. Sizes 3" to 9" (76 – 230 mm), rigid for heavier loads, semi-rigid for tighter holes.
Pick SLUMPSTOPPA™ when you're loading emulsion in underground upholes and need a gas-permeable retention device to hold the column without compromising the gassing reaction. Polymer bristles with a stainless steel spine hold the column while letting emulsion gas through. Fits 2.5" to 4.5" (64 – 115 mm). The dedicated emulsion-slump solution for underground upholes.
