What problems did you encounter at your mining site?
When the power goes out, production stops; crushing, pump stations and camps need backup power.
After expansion, the system cannot carry the added loads; crushers and pumps trip as soon as they start.
Without stable power at a new mine or expansion site, construction and installation slow down.
If dewatering pumps and tailings equipment lose power, water buildup, safety risks and environmental risks rise.
For remote mines relying on long-term self-generation, fuel consumption and refueling logistics drive operating cost
Aging generators with high fuel consumption and frequent faults should be reviewed before expansion to decide whether replacement or paralleling is the better path.
4 steps to help you clarify your purchasing needs
01
Confirm the type of on-site power supply problem
Start with the real site problem: outages, voltage fluctuation, expansion loads the current system cannot carry, dewatering backup, temporary construction power, fuel cost or aging equipment. This allows the engineering team to scope the power system around the mine's operating risk, not just a kW number.
Determine on-site problems 02Recheck which loads need protected power
Crushing, screening, conveyors, pump stations, camps, maintenance workshops, and safety-critical loads cannot be reviewed by total kW alone; check starting method, simultaneous operation, and outage priority.
Review the load list 03Confirm the scope of the entire power supply system
What a mine site often needs is not one standalone generator set, but coordinated operation across the generator set, ATS, paralleling system, low-voltage distribution, fuel system, remote monitoring, and spare parts.
View system configuration 04Confirm after-sales service scope and fees
Before quoting, confirm installation and commissioning, operator training, spare parts kit, remote diagnosis, local support, response time, and which services are included or billed separately.

Open the mining country centerAfter-sales support for delivery and operation
Equipment purchase is only the start; after-sales support must keep up
Buying equipment is just the beginning. What the mining area really needs to confirm is who is responsible for installation inspection, commissioning assistance, operational training, spare parts preparation, fault diagnosis and service response after the equipment arrives at the site.
Who is responsible for installation and commissioning?
When equipment arrives, confirm foundations, grounding, cables, low-voltage distribution, ATS, paralleling conditions, and the first loaded commissioning plan.
How on-site personnel operate and maintain
Startup and shutdown, load switching, alarm viewing, inspection records and daily maintenance requirements must be handed over to the person in charge of the site.
Are common spare parts prepared in advance?
Confirm spare parts packages such as filters, belts, sensors, controllers, AVRs, etc. in advance based on operating hours and remoteness.
How faults are diagnosed and handled after they occur
When a fault occurs, use operating records, alarm information, and site photos to identify the issue first, then arrange remote diagnosis, local coordination, and service response.
After-sales service must be confirmed clearly before quotation and delivery to avoid failure in installation, spare parts, remote diagnosis, local collaboration and fault response after the equipment arrives.
Construction risk prevention
Avoid 12 common risks in mine power system planning
Start with the issues most likely to cause production stops, tripping, runaway fuel consumption, or after-sales delays. The full list is available item by item in the risk guide.
No spare parts and maintenance plan
Remote mine sites are not just afraid of major failures. Filters, belts, sensors, controllers, AVRs, pumps and electrical parts are not ready, and minor failures can cause downtime for several days.
Dewatering, tailings, and safety equipment need independent backup power
Dewatering pumps, tailings pumps, water treatment, and safety monitoring should stay powered even when ordinary production loads stop. Before construction, confirm which safety loads need independent backup power.
Prime and backup power are not separated
Having a generator does not mean the site has standby power. Before configuration, clarify which loads are covered by the prime supply, standby supply, and ATS transfer during an outage.
Generator capacity is there, but distribution and cabling lag behind
A large generator alone is not enough. If low-voltage cabinets, breakers, cables, and load zoning are undersized, the site can still see voltage drops and trips. Distribution should be checked before procurement.
Sizing only by equipment kW
It is easy to underestimate the startup impact of crushers, water pumps and air compressors by only looking at the equipment nameplate power. Before purchasing, review the starting current, simultaneous operation and expansion margin.
No power capacity was reserved before expansion
Expansion is not just about adding a new piece of equipment, power capacity, power distribution, cables, fuel and spare parts must keep up. Otherwise, the new equipment may not be able to be started after it arrives at the site.
Fuel cost not calculated
In remote mine sites, the real cost is diesel, transport, maintenance and downtime. Compare generator options by total operating cost, not purchase price alone.
Tank and refueling route
Having a generator does not guarantee stable power. If the day tank, bulk tank, refueling frequency and transport route are not calculated, the unit can still stop for lack of fuel.
Mine power case review
How HOHANK engineers address outages that affect production, dewatering and camp power at the same time
The customer first asked about a standby diesel generator. As engineers learned more about the mine site, the real issue became clear: an outage would affect the production line, dewatering pumps, camp power and communications at the same time. The engineering review covered key loads, startup sequence, ATS transfer, low-voltage distribution, fuel supply and after-sales response, helping the customer avoid buying one piece of equipment that still could not carry the load, protect dewatering, power the camp or prevent later distribution rework and production delays.
The customer first described an initial need
At first, the customer only said that mine power was unstable and they wanted to add a standby diesel generator. The engineer did not quote from a power table right away; first, they asked when outages usually happened and which equipment would be forced to stop.
Engineers clarified the mine's power needs
After more discussion, the site issue became clear: the crushing line, dewatering pumps, camp lighting, communications, and maintenance workshop all depended on the power system, and dewatering and safety-critical loads could not wait for manual switching.
Engineers help customers avoid undersized power configurations
If the generator set is sized only by the minimum power, the price may look lower, but crushers and water pumps can cause voltage drop or breaker trips at startup, with no margin left after expansion. Engineers rechecked starting current, simultaneous operation relationships, and key-load priority.
Engineers clarified the full power-system plan with the customer
After the review, engineers made clear that the purchase scope should not stop at one diesel generator. The customer needed to confirm the diesel generator set, ATS, low-voltage distribution, fuel system, monitoring interface, and common spare parts together.
Engineers provide access, commissioning and engineering guidance
Before the equipment arrives, engineers list foundations, cables, grounding, lifting, fuel lines, exhaust, startup tests, load tests, and operator training one by one. The site team knows what to prepare first and how to connect and commission the system after delivery.
After a problem occurs, engineers help diagnose it immediately.
During operation, if alarms, trips, or starting difficulties occur, engineers first use controller photos, fault codes, operating hours, and maintenance records to identify the problem scope, then arrange remote diagnosis or local coordination.
The engineer explained: The main concern is when customers focus only on the lowest power rating and the price of one generator set while overlooking site integration, distribution and after-sales response. That can ultimately affect production, dewatering and camp power. The engineering goal is stable, safe and cost-controlled power for mine production and daily operations.
