SLUMPSTOPPA™ is a bottle brush–style uphole retention device used in emulsion blasting to control slumping during loading.

In underground operations, emulsion can slump back in upholes while charging. That wastes product, creates mess, and makes collar height inconsistent. SLUMPSTOPPA™ is inserted into the blasthole during loading to help retain the emulsion column where it belongs.

On site, many blasters call it a bottle brush. And visually, it looks similar. But its job isn’t cleaning. It’s charge control.

The polymer bristles fold back during insertion, allowing the device to be pushed several meters into the hole. Once in place, the bristles help hold the emulsion in position while still allowing gassing to occur. This helps maintain correct collar height and improves loading consistency.

SLUMPSTOPPA™ is commonly used in underground emulsion blasting where clean loading, reduced waste, and better housekeeping matter. It’s resistant to emulsion chemicals and designed around global best practice for explosive loading.

Used for:

• Emulsion blasting in underground mining
• Uphole charge retention
• Controlling emulsion slumping during loading
• Improving collar height consistency
• Reducing wasted emulsion and cleanup

Key features:

• Bottle brush–style bristle design
• Flexible polymer bristles with stainless steel spine
• Allows emulsion gassing while retaining charge
• Resistant to emulsion chemicals
• Designed to reconcile with AS 2187.2 best practice

If emulsion slumping is an issue during loading, SLUMPSTOPPA™ provides a simple, proven way to keep the charge where it needs to be.
