Electrical pit avoidance guide
Suitable for new mine construction, expansion, trial production, old machine renewal and long-term self-power generation in remote mining areas. Here we do not talk by product, but we break down the electrical problems in mine construction that are most likely to cause production shutdowns, tripping, drainage risks, out-of-control fuel consumption and waiting for maintenance.
Problem classification and processing direction
Customers can first find the risk type by on-site problem, and then enter the solution, product module, project review, installation after-sales or contact form to avoid not knowing what information to prepare next after reading the article.
If the problem occurs in the startup of the crusher, water pump, air compressor, or conveyor belt, or the equipment cannot be started after expansion, first enter the capacity and starting current review path.
If there are generators on site but voltage drops and trips persist, or drainage, tailings, communications, and campsites need priority to maintain power, distribution, ATS, and load zoning should be reviewed at the same time.
If the mining area is remote, it is difficult to replenish oil, the altitude is high, the dust is heavy, or the impact of the rainy season is obvious, the power supply plan must include the fuel tank, oil replenishment route, derating, and maintenance cycles.
If the old generator is still struggling to expand production, or if there are minor on-site faults that are always waiting for parts, people, and repeated alarms, the old machine updates, spare parts packages, and operation records should be placed in the same after-sales path.
12 common power risks
Each article only explains one question thoroughly. Mine owners, operations leaders and EPC teams can use it to conduct an electricity risk check before construction, expansion, diesel generator selection or old machine replacement.
Remote mining areas 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.
Suitable for long-term self-generation in remote mining areas, trial production delivery, old machine renewal and confirmation before establishment of operation and maintenance system
A problem that could have been restored within a few hours was delayed for several days because there were no people, no parts, and no plans. Production and drainage safety were both affected.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
Drainage pumps, tailings pumps, water treatment and safety monitoring cannot be powered off together with ordinary production loads. Before construction, it is necessary to confirm which safety loads must be independently powered.
Suitable for pre-monsoon, underground operations, tailings systems, water treatment stations and safe load review
Once the production power supply is stopped, the key safety loads are also stopped, and the site changes from production shutdown to safe disposal.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
Having a generator does not mean having a backup power supply. Which loads are protected by active, backup and ATS switching during a power outage need to be clarified in advance before configuration.
Suitable for review of new mines before production, transition from temporary power supply to formal power supply, grid access and backup power supply
Key equipment was shut down when it was supposed to maintain power, and the scene changed from power outage recovery to production shutdown, safety disposal, and manual switching chaos.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
The generator capacity is large enough, but if the low-voltage cabinets, circuit breakers, cables and load partitions do not keep up, there will still be voltage drops and trips on site. When purchasing, the power distribution should be reviewed together.
Suitable for expansion, phased construction, long temporary lines, generator renewal and distribution system review
The host seems large enough, but power cannot be sent to the device, and the entire power supply system is still unstable.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
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.
Suitable for production expansion, trial production, crushing line and pump station start-up confirmation
It seems that after buying enough power, it cannot be started on site, and the entire shift of production is delayed by repeated restarts.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
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.
Suitable for new production lines, upgrading equipment, new mining areas, and confirmation before construction and trial production.
The equipment has arrived at the mine, and civil construction and installation have been completed, but it cannot be put into production due to insufficient power.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
Remote mining areas have long-term self-generated power, and the real big costs are often diesel, transportation, maintenance and downtime costs. When comparing prices, don’t just look at the purchase price of the generator.
Suitable for long-term off-grid self-power generation, production expansion in remote mining areas, old machine renewal and procurement plan comparison and selection
It was cheap on paper, but its long-term operation was hampered by fuel consumption, supplies, maintenance and shutdowns, and the cost of power generation gradually got out of control.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
Having a generator does not mean that there is stable power on site. Daily fuel tanks, large fuel tanks, replenishment frequency and transportation routes are not well planned, and the unit may shut down due to lack of oil.
Suitable for remote mining areas, rainy season construction, continuous production, camp and unit layout plan confirmation
The equipment is not broken, but the power supply plan is interrupted due to poor oil replenishment, insufficient fuel tanks, or the inability of supply trucks to enter.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
Production, drainage, tailings, camp and maintenance loads cannot all be mixed together for power supply. Before construction, it is necessary to distinguish between critical loads and ordinary loads to avoid a single fault halting the entire mine.
Suitable for new mine construction, temporary power conversion to formal power supply, simultaneous expansion of camps and production
When a problem occurs in one area, production, drainage, lighting, communications and maintenance are all affected.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
High altitude, high temperature, dust and rain will all affect the actual output of the unit. Just because the capacity on paper is sufficient does not mean that it will be able to be carried at the mine site.
Suitable for high-altitude mining areas, open-pit mines, rainy season construction, high dust crushing areas and review of unit layout plans
The paper power is sufficient, but the on-site power is not enough, and fuel consumption, alarms, faults, and shutdowns all increase.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
Old machines continue to support the expansion of production. The common problems are not a single failure, but increased fuel consumption, difficulty in finding spare parts, and increased downtime. Before expanding production, it is necessary to determine whether to update or parallel the machine.
Suitable for updating old machines, review before production expansion, mining areas with frequent failures and long-term self-generation cost inspection
After expanding production, it seems that the purchase money is saved, but it is actually eaten up repeatedly by maintenance, downtime, fuel consumption and production losses.
First explain the on-site phenomenon, equipment list or existing problems, and the engineer will help you determine whether further review is needed.
Without records of operating hours, loads, alarms, and failure times, it is difficult for engineers to determine the real cause. Remote monitoring and logging can reduce repeat failures.
Suitable for long-term spontaneous power generation mining areas, frequent fault sites, remote service support and post-production operation and maintenance management
There are repeated problems, repeated shutdowns, and repeated repairs. On-site firefighting is always based on experience, and traceable judgments cannot be formed.
