Mine power supply solution

If you encounter electricity problems at the mining site, first look at the corresponding solutions.

Grid instability, broken starts, pumping and drainage, high altitude, fuel costs, remote after-sales or old machine replacement, first enter according to on-site problems, and then the engineer will judge what kind of power generation, ATS, parallel machine, power distribution, fuel and service configuration are needed.

Mine power supply diagnosis

First determine what type of problem the mine power supply is stuck in

Mine power supply does not mean buying equipment directly based on power. First look at the power supply conditions, critical loads, on-site working conditions and follow-up support, and then judge the generator set, ATS, parallel machine, power distribution, fuel and service scope.

There is no stable power grid in the mining area, or the power grid frequently fluctuates

01 ·Basic power supply conditions

There is no stable power grid in the mining area, or the power grid frequently fluctuates

Loads such as crushing, conveying, pumping stations, maintenance workshops and camps require stable main power and clear switching logic.

May affect:If the generator is only used as a temporary backup, voltage fluctuations or power outages will affect production, drainage and domestic loads.

The power supply cannot keep up during the construction, expansion or trial production stages of new mines.

02 ·Basic power supply conditions

The power supply cannot keep up during the construction, expansion or trial production stages of new mines.

Construction camps, drilling rigs, welders, temporary breaking lines, water pumping and lighting need to be stable before the formal power system can operate.

May affect:Temporary insufficient power supply will slow down civil construction, equipment installation and trial production, and may cause repeated changes in power distribution during later expansion.

Crushing, screening and conveying lines lose power as soon as they are started

03 · Critical load risk

Crushing, screening and conveying lines lose power as soon as they are started

Crusher, screening machine, feeder, conveyor belt and motor control cabinet will affect the rhythm of the entire production line at the same time.

May affect:If the unit is selected based on operating power only, the startup shock will cause voltage drop, tripping and shutdown of the entire line.

Drainage pumps, tailings and safety loads cannot be powered off

04 · Critical load risk

Drainage pumps, tailings and safety loads cannot be powered off

Drainage pumps, tailings pumps, control boxes, safety equipment and continuous operating loads in rainy seasons need to give priority to ensuring power supply.

May affect:Once the power is cut off, water accumulation, safety risks, environmental risks, equipment damage and forced shutdowns may occur.

05 · On-site working condition constraints

High altitude, high temperature or dust lead to insufficient output of the unit

High altitude, day and night temperature differences, dust and long operating conditions are common in Andean mines.

May affect:A unit with sufficient book capacity may experience power shortages on site due to altitude, temperature and heat dissipation conditions.

For remote mines relying on long-term self-generation, fuel and operating costs are difficult to control.

06 · On-site working condition constraints

For remote mines relying on long-term self-generation, fuel and operating costs are difficult to control.

Diesel transportation distance, daily fuel tanks, bulk tanks, refueling routes, operating hours and load factors all affect long-term costs.

May affect:Without fuel consumption estimation, refueling intervals and load optimization, mine power costs will continue to amplify over the long term.

Old generators have high fuel consumption and many faults. Before expanding production, it is necessary to decide whether to update or parallel them.

07 · Operation guarantee

Old generators have high fuel consumption and many faults. Before expanding production, it is necessary to decide whether to update or parallel them.

The existing units have long operating hours, frequent failures or insufficient capacity. At the same time, new crushing, pumping stations or workshop loads may be added to the mining area.

May affect:Continuing to support old machines will increase fuel consumption, downtime, maintenance and temporary remediation costs, and it is easy to be held back by the old system when expanding production.

After the equipment was shut down, spare parts and after-sales response could not keep up.

08 · Operation guarantee

After the equipment was shut down, spare parts and after-sales response could not keep up.

Filters, belts, sensors, controllers, AVRs, debugging records and operator training all affect recovery speed.

May affect:A small failure may also turn into a long-term downtime due to lack of spare parts, lack of diagnosis, and lack of local support.
