Solar Pump Systems for Gold Mine Drilling and Blast-Hole Water
Introduction
Drilling and blasting move the rock that a gold mine processes, and drilling—whether exploration, grade control or production blast holes—needs water. Water suppresses dust at the bit, cools the steel, and keeps the hole stable; without it, drilling stalls, dust plumes breach licence limits, and crews are exposed. At a remote African site that drilling water is usually hauled or pumped by diesel. A solar pump delivers it off-grid, quietly, right where the rigs are. This article covers solar pump systems for gold-mine drilling and blast-hole water, from specialists at KINBO.

The Drilling Water Duty
- Dust suppression at the bit—water injected down the drill string keeps silica dust down, a core health and licence requirement.
- Bit cooling and flushing—water carries cuttings out of the hole and cools the steel so penetration rates hold.
- Mobile demand—drill rigs move across the pit; water must follow them, so a mobile tank filled by solar is the usual pattern.
- Blast preparation—some mines pre-wet blast holes or the muck pile; a steady supply supports both.
This is the operational sibling of exploration supply (our exploration guide)—here the duty is production-scale and continuous.
Selecting the Drilling Pump
- Centrifugal or diaphragm transfer—fills the rig’s on-board tank from a solar-filled cache; a small, robust pump is enough because the rig stores its own water.
- Pressure for down-hole injection—if the pump feeds the drill directly, size for the injection pressure; a VFD-style solar controller holds it steady.
- Source—from a bore (our deep-borehole guide) or a collected surface supply; size for the rig’s make-up rate.
- Portability—a skid or trailer-mounted solar pump follows the drill fleet, avoiding long pipe runs across the pit.
Solar Drive and Delivery
- Cache-and-fill model—the solar pump fills a static tank or water cart; rigs draw from it as they work. This decouples solar pumping from the rig’s exact location.
- Buffer tank—an elevated tank keeps the cache topped so drilling never waits for sun.
- Hybrid backup—for continuous drilling campaigns, a hybrid controller ensures the cache never runs dry through cloud.
Solar vs Diesel Drilling Supply
| Factor | Diesel Drilling Supply | Solar Drilling Supply |
|---|---|---|
| Energy cost | Per run-hour, perpetual | Zero after install |
| Dust-compliance risk | Fuel-out stops suppression | Buffer keeps rigs watered |
| Mobility | Fuel cart follows rig | Solar cache follows rig |
| Best fit | Grid-connected sites | Off-grid / remote pits |
Drilling without water is a dust and licence breach, not just a slowdown—so a reliably watered rig is a compliance asset. Our cost analysis quantifies the saving.
Frequently Asked Questions
Can solar keep up with a drill fleet?
Use a solar-filled cache tank the rigs draw from; size the array to the fleet’s total make-up rate and the buffer covers gaps, so drilling never waits for sun.
Does the pump feed the bit directly?
Either—a small pump can top up the rig’s tank, or a higher-pressure pump feeds injection directly. We size to whichever your rigs use.
What about exploration drilling?
The same model serves exploration (our exploration guide); production drilling just scales the flow and adds mobility so the cache follows the fleet.
Can it run through cloud?
A buffer tank carries normal cloud; for continuous campaigns a hybrid tops up only when the buffer is low, so drilling water never stops.
