Water management is one of the most complex & critical challenges in underground mining. From groundwater ingress & equipment hazards to environmental containment & safety compliance, poor water control can lead to costly delays & increased risk underground.
SAP HD (Super Absorbent Polymer – Heavy Duty), developed by Polymer Innovations, offers a proven solution to absorb, retain & stabilise water in underground conditions. Designed for high-performance applications in demanding environments, SAP HD is changing the way underground mining operations manage water on-site.
The Underground Water Challenge
In underground mining, unwanted water can seep into development headings, shafts, sumps & storage areas. It can accumulate rapidly through groundwater infiltration, drilling operations, or accidental discharge & create significant hazards:
- Slippery & unstable walkways
- Bogged equipment & poor site access
- Structural instability in backfill or storage areas
- Delays in drilling, blasting, or transport
- Increased pumping & dewatering costs
Traditional approaches such as mechanical dewatering or temporary diversion require time, energy & infrastructure. In contrast, SAP HD offers fast, reliable water containment & solidification with minimal handling or setup.
What Is SAP HD?
SAP HD is a high-performance super absorbent polymer engineered to absorb large volumes of water, up to 300 times its weight, depending on salinity. Supplied in granular form, it activates upon contact with water & forms a stable gel that locks moisture in place. Unlike traditional absorbents (e.g. sawdust or sand), SAP HD is lightweight, easy to transport, & effective in confined spaces, making it ideal for use underground where space & time are limited.
Key Applications in Underground Mining
1. Rapid Response to Water Ingress
When water enters development headings, stope access points or decline levels, immediate response is critical. SAP HD can be applied directly to pooled or seeping water, where it rapidly absorbs & solidifies the moisture. This helps crews regain safe access & reduce hazards quickly without waiting on pumps or infrastructure.
2. Sump Management & Pump Protection
Sumps play a vital role in underground drainage, but they can become overwhelmed by sudden inflows or sediment-heavy water. SAP HD helps stabilise sump contents by absorbing excess free water, reducing pump demand & allowing for easier cleanout & solids management. It also prevents water from overflowing into adjacent work areas, keeping operations cleaner & safer.
3. Backfill Control & Water Stabilisation
Backfilling in stopes or development drives often requires managing water content. SAP HD can be blended into backfill material or applied to wet areas to stabilise moisture content, reducing slumping, leakage, or instability. In temporary fill or barricade zones, SAP HD provides added control & consistency, particularly when handling variable water volumes underground.
4. Emergency Spill & Leak Containment
Leaks from process lines, sumps or tanks can lead to rapid flooding or contamination. SAP HD can be stored underground in sealed containers & deployed quickly for emergency containment, absorbing water or non-hazardous fluid spills & forming manageable gel masses for safe disposal.
Why SAP HD Is Ideal for Underground Use
Underground mining conditions demand materials that are fast-acting, low-volume & easy to apply in tight spaces. SAP HD meets these needs with:
- High absorption capacity in both freshwater & saline water
- Fast gel formation; within minutes of contact
- Safe for confined spaces, with no toxic vapours or hazardous residue
- Compact & portable packaging for easy transport underground
Because SAP HD is supplied in dry form, it has a long shelf life & can be stored on site for on-demand water control.
