Mines need power at all times. Without electricity, equipment stops working, and operations grind to a halt. In many cases, mines are located in remote areas where there is no stable power grid. This is where a diesel generator comes in. It is a simple and effective solution to ensure electricity is available anytime, under any conditions.
A diesel power generator delivers high output, long autonomy, and safe operation even in harsh environments. That’s why it’s used in almost every mining project in Romania. It’s an investment that can make the difference between uninterrupted production and significant losses caused by unplanned outages.
Why You Need a Diesel Generator in Mining Operations
Mining operations require power at every stage of work. Large machinery, ventilation systems, pumps, lighting equipment, and more depend on a constant energy supply. This is especially true in underground environments, where safety relies directly on the proper functioning of installations.
Without power, production stops. More critically, there can be risks to human safety. For example, in an underground mine, the lack of ventilation can lead to the accumulation of toxic gases. Without lighting, serious accidents may occur. This is why generators are not optional – they are essential for safety and operational continuity.
Another major reason is grid instability. In some areas, grid power is prone to frequent outages or voltage fluctuations. This can damage equipment and cause sudden stoppages of machinery. A reliable generator protects systems, maintains stable parameters, and reduces the risk of damage.
Types of Diesel Generators Suitable for Mining Operations
Diesel generators for mining must be powerful, durable, and easy to maintain. Depending on the application, several types can be used. The choice depends on the type of activity, the required mobility, and the operational regime:
Stationary Generators – These are fixed units, with power ratings between 400 and 2500+ kVA. They are ideal for areas with constant, high-intensity operations. They can be equipped with soundproof enclosures to reduce noise. Installed on solid foundations, they are permanently connected to internal distribution systems.
Stage V Generators – Compliant with European emission standards, these are suitable for projects with strict environmental requirements or those funded by European grants. They produce less smoke and are more fuel-efficient. An excellent choice for companies focused on sustainability.
Portable Generators – Smaller and easy to move, these are useful in temporary work zones or where quick interventions are needed. Commonly used for maintenance teams, emergency pumps, or temporary lighting.
Extended Autonomy Generators – In some cases, the generator must run 24 hours without refueling. For this, Zenessis offers models with large fuel tanks and low consumption. These are essential for long shifts where frequent refueling is not possible or safe.
Proper Installation of a Diesel Generator in a Mining Area
Proper installation is vital for safety and performance. First, the generator should be placed on a stable surface, sheltered from rain, wind, or dust. The floor must be level and able to support the total weight of the equipment. There must also be enough space for ventilation and maintenance access.
The area must be well-ventilated. Hot air and exhaust gases need to be vented outside through ducts or pipes. If the generator has a soundproof enclosure, it can be installed outdoors without concerns about noise or weather. Direct contact with water sources or flammable materials should be avoided.
Electrical connections must be made by a certified electrician. All cables should be checked and protected. The generator must be properly grounded to prevent short circuits or electric shocks. It must also be compatible with the load requirements – capable of powering equipment without overloading or causing phase imbalance.
Maintaining Diesel Generators in Harsh Conditions
The mining environment is tough. Temperatures are extreme, humidity is high, and dust is constantly present. That’s why the generator must be maintained regularly and carefully.Every day or week, you should check the levels of oil, fuel, and coolant. Filters, belts, cables, and battery terminals should also be inspected.
At longer intervals, consumables must be replaced: oil, filters, and possibly belts. Air filters should be cleaned, used oil drained, and load testing performed. A maintenance log is recommended to keep track of all operations.
If the generator is not used daily, it is recommended to start it once every two weeks for at least 30 minutes. This prevents defects caused by inactivity, battery discharge, or condensation build-up.
Zenessis provides remote technical support, mobile service teams, and original spare parts. This makes maintenance simple and keeps the generator in good condition. Additionally, remote diagnostics allow for quick interventions in case of problems.
Benefits of Using Zenessis Generators in Mining Applications
Zenessis has been producing generators for over 100 years. Their models are used in Romania and Germany. In mining, durability, autonomy, and ease of maintenance are crucial. Zenessis generators are built for such conditions. They are tested under heavy-duty regimes and adapted to local realities.
The engines come from well-known brands: Volvo, Perkins, Doosan, Baudouin. The generators can run for hours on end without stopping. Noise levels are reduced, even in large models. Consumption is also optimized to lower costs, which helps the overall efficiency of the project.
For special projects, generators with advanced features are available: automation panels, remote monitoring, and phone control. These features provide complete control over the equipment and reduce downtime.
An example: In a quarry in Bihor County, a 1250 kVA generator with 24-hour autonomy was installed. Since then, operations have continued without interruptions, and fuel consumption has dropped by 18%. Moreover, maintenance has become easier thanks to convenient component access and the technical support provided.
Frequently Asked Questions About Diesel Generators for the Mining Industry
How often should the generator be maintained?
Basic checks should be done daily or weekly. Oil and filter changes – according to the manual. Typically, every 250 or 500 hours, depending on the model and working conditions.
Is it allowed to use a gasoline generator?
Technically, yes. But it’s not recommended. They have low autonomy, high consumption, and are less safe in industrial environments. Diesel is more stable and better suited for heavy loads.
What noise level is acceptable?
According to HG 1756/2006, generators under 400 kW must not exceed 98–102 dB. Zenessis offers models under 75 dB, with soundproof enclosures, ideal for areas where noise is a concern.
Is a permit required for installation?
It depends on the application and location. In protected or subsidized areas, yes. It is recommended to discuss with a Zenessis technical consultant to understand all local requirements.
Conclusion and Final Recommendations
In mining, power cannot be absent. Diesel generators are a safe and efficient solution. Choosing the right model depends on real needs: consumption, location, type of equipment. It’s important to consider working conditions, maintenance intervals, and operating costs.
Zenessis offers reliable generators, tested in harsh conditions, and free consultancy. If you work in the mining sector and need a stable power supply solution, a diesel generator is a logical choice.
