In the demanding world of mining, power is more than a utility—it's the lifeline that keeps every operation moving forward. From the first drills breaking ground during site preparation to the continuous hauling of ore from deep pits, mining infrastructure relies on a steady, robust supply of electricity. When grid connections prove unreliable or simply do not exist, diesel generators step in as the primary—and often only—source of power. ZHEJIANG UNIVERSAL MACHINERY CO., LTD. (UnivPower) specializes in diesel generator solutions tailored to the unique challenges of the mining sector, ensuring that compressors roar, concrete mixers churn, and safety systems stay online.
Before a single ounce of ore is extracted, a mining project undergoes an intensive construction phase. This stage—often referred to as site development or mine infrastructure setup—includes:
Access Roads and Bridges: Grading, paving, and bridgework require heavy earthmoving equipment and continuous lighting for round the clock safety.
Foundations for Processing Plants: Concrete pours for crushers, mills, and flotation tanks demand high volume mixing and pumping.
Water Management Systems: Dewatering pumps and sediment control measures keep excavations dry and environmentally compliant.
Temporary Buildings: Workshops, storage sheds, and security checkpoints need lighting, HVAC, and power outlets.
Communications and Control Centers: Radio towers, satellite dishes, and fiber optic hubs support remote monitoring and coordination.
These parallel tasks often occur simultaneously, driving up the overall power requirement to hundreds—or even thousands—of kilovolt amperes (kVA). Mining sites are commonly located in arid deserts, dense jungles, or polar regions—far from reliable grid infrastructure. Even where lines exist, mountainous terrain or seasonal storms can interrupt supply for days. A delay in establishing power can stall the entire project, incurring millions in lost opportunity costs. Diesel generators provide an immediate, scalable solution: they can be delivered on site, installed within days, and configured to handle diverse electrical loads from day one.
Drilling rigs used for blast-hole preparation and core sampling rely on high pressure air. Diesel driven rotary screw compressors draw power from on site gensets to produce up to 40 bar of pressure:
Impact resistant designs withstand dust and vibration in open pit environments.
Variable speed drives, powered by the generator's digital governor, adjust motor RPM to match demand—optimizing fuel use.
Oil injected screws ensure continuous operation with minimal maintenance, crucial when servicing visits are infrequent.
Infrastructure elements such as crusher foundations and processing plant slabs require large scale concrete work:
Static Mixers: Often 5–10 m³ capacity, these units draw 30–250 kVA to run high torque drum motors.
Concrete Pumps: Capable of delivering over 100 m³/hour under pressures up to 100 bar, they can demand inrush currents up to 8× their running amps. A robust generator must tolerate these surges without tripping.
Continuous Duty: For multi day pours, gensets operate 24/7, demanding a continuous operating rating (ISO 8528 G3/G4) that assures full load delivery indefinitely.
On site fabrication of steel structures and piping spools necessitates arc welders and plasma cutters:
Arc Welders: Require stable voltage (<±1% deviation) to produce sound, spatter free welds.
Plasma Cutters: Electronics in CNC-guided systems need precise frequency control (<±0.5 Hz) to maintain cut quality.
Shared Bus Systems: Multiple welding units can be paralleled on a single generator bus, demanding careful load management and sequenced start stop control via programmable logic.
Handheld power tools—grinders, drills, and saws—plus floodlighting for night shifts, add intermittent but critical loads:
Surge Tolerance: Generators must handle multiple small motor starts in quick succession.
Inverter grade Output: For sensitive electronics like laptops in the site office, an inverter or diesel inverter hybrid genset provides clean sine wave power (<3% total harmonic distortion).
By sizing gensets to accommodate these varied loads—and by utilizing features like automatic load shedding—UnivPower ensures that every compressor, mixer, and welder operates at peak efficiency without jeopardizing grid integrity or safety.
Construction sites often host hundreds of workers and essential life support systems:
Power for HVAC: Air conditioners or heaters maintain livable conditions in camps and offices, requiring 20–100 kVA per building cluster.
Water Treatment and Sewage: Pumps for potable water and wastewater require steady power to comply with health regulations.
Communications: Satellite uplinks, radio repeaters, and Wi-Fi towers keep teams connected, demanding low noise, uninterrupted power.
Mining sites must adhere to stringent safety protocols:
Fire Pumps and Fire Suppression: Must switch to backup power within 10 seconds of grid failure; gensets integrated with an ATS (Automatic Transfer Switch) accomplish this automatically.
Gas Detection and Ventilation: Underground or pit bottom installations rely on continuous monitoring. Failsafe power ensures alarms and fans operate even during blackouts.
Medical Facilities: On site clinics need reliable lighting, diagnostic equipment, and sterilization machines—a power interruption could risk lives.
Perimeter Fencing and Lighting: Infrared cameras and floodlights deter intruders and wildlife hazards.
Access Control Systems: Electronically locked gates and biometric scanners require steady voltage to prevent unauthorized entry or lock outs.
UnivPower's gensets are paired with advanced ATS and remote monitoring platforms, guaranteeing that even non industrial loads—like offices and safety systems—receive the same level of uninterrupted service as heavy machinery. This holistic approach to site power management simplifies operations and fortifies compliance.
A generator's technical specifications determine its ability to sustain demanding loads while optimizing operational costs. Two factors stand out in mining applications: continuous duty rating and fuel consumption.
ISO 8528 G3/G4 Certification: Ensures the generator can deliver its rated power output indefinitely under proper maintenance.
Robust Cooling Systems: Heavy duty radiators, thermostatically controlled fans, and coolant additives prevent overheating during extended operation.
Industrial Grade Alternators: Brushless, drip proof, and self ventilated designs resist dust, moisture, and vibration—common hazards on mining sites.
Mining projects often extend for years. A genset that falters under prolonged stress not only halts production but necessitates expensive downtime for repairs or replacement. Continuous run capability is non negotiable.
Fuel logistics in remote locations involve significant time and cost:
High Pressure Common Rail Engines: Precise fuel metering improves combustion efficiency by up to 10% compared to older unit injector designs.
Load Dependent Speed Control: Generators equipped with digital governors reduce engine RPM under light loads, cutting fuel burn by up to 20% during idle periods.
Hybrid Integration: While diesel remains primary, pairing with solar arrays or battery storage allows gensets to idle or shut off during peak solar production, further reducing fuel needs.
UnivPower's engineering team conducts site specific fuel consumption modeling during the project planning phase. By predicting daily kWh demands and overlaying fuel logistics costs, they recommend the optimal genset size and control strategy—minimizing total cost of ownership over the mine's life.
No two mining sites are identical. UnivPower's strength lies in translating this variability into bespoke generator packages:
Comprehensive Surveys: UnionPower engineers collaborate with site teams to catalog every electrical load—static and dynamic.
Safety Margins: Recommended genset capacities include a 20–30% buffer for future expansions or unplanned load spikes.
Zoning: Separate generator circuits for heavy machinery, living quarters, and safety-critical systems allow prioritization and load shedding under strain.

Automatic Transfer Switches (ATS): Ensure sub 10 second switching times, connecting critical loads to backup power without human intervention.
Remote Monitoring Platforms: Cloud based dashboards with SMS/email alarms give site managers real time visibility into generator health—fuel levels, oil pressure, coolant temperature, and load profiles.
Custom Canopies: Sound attenuating enclosures keep noise below regulatory thresholds (often <75 dB(A) at 7 m), while corrosion resistant paint and stainless steel fixtures endure harsh environments.
Mobility Packages: Trailer mounted skids, forklift pockets, and lifting lugs allow rapid redeployment as the construction footprint evolves.
Environmental Protections: Bunded fuel tanks, spill containment trays, and secondary drip pans satisfy ecological regulations in sensitive areas.
