PowerPlug – small diameter hole plugging device

PowerPlug – Engineered for Underground Mining

The PowerPlug is the ultimate tool to optimize your blasting operations. Designed to effectively plug small diameter blast holes, this innovative device ensures maximum retention of explosive energy, leading to superior fragmentation, reduced overbreak, and improved overall productivity.

Made from durable, high‑quality materials, the PowerPlug is easy to install and designed to withstand the harsh conditions of underground mining. Whether you're looking to enhance productivity, improve safety, or achieve better blasting results, the PowerPlug is your go‑to solution.

Why PowerPlug

Key Features & Benefits

Enhanced Safety

By securing explosive energy within the blast hole, the PowerPlug minimizes fly rock and reduces the risk of unintended detonation. Your crew stays safer.

Maximum Energy Retention

Optimises explosive confinement, delivering superior fragmentation and reduced overbreak. More energy where it counts – in the rock.

Easy Installation

Simple, fast placement in small‑diameter holes. Requires no special tools or extensive training – your team can deploy it immediately.

Durable Construction

Made from high‑grade materials to withstand abrasion, moisture, and pressure. Reusable where practical, lowering consumable costs.

Cost Effective

Reduces explosive wastage, lowers secondary breakage, and improves cycle times – delivering a rapid return on investment.

Performance Analytics

Integrates with our DIS platform to track blast outcomes, fragmentation, and energy efficiency across every blast.

Gold‑Fields South Deep Deployment

2025 Success Story

Thuthuka Mining Services partnered with Gold‑Fields to introduce the PowerPlug across multiple development ends at South Deep mine. Results after 3 months:

  • 22% better fragmentation – less oversize, faster loading
  • Zero fly‑rock incidents – improved safety metrics
  • 15% faster cycle times – reduced secondary breakage
  • 8% reduction in explosive consumption per tonne blasted

“The PowerPlug has transformed our development blasting. We've seen measurable improvement in fragmentation and our safety metrics around fly rock have never been better.” – Blasting Superintendent, Gold‑Fields South Deep
