Over a two-year research initiative, TU Delft and HCME are working closely to study and forecast the lifespan of key components in mining machinery such as dump trucks and excavators. The ultimate goal is to increase the availability, dependability, and safety of this equipment while simultaneously reducing life-cycle costs and minimizing downtime. With the involvement of advanced sensors, real-world datasets, and expert knowledge from both industry and academia, this project marks a significant step toward smarter, more sustainable mining.
The Importance of Predictive Maintenance in Mining
Mining operations are notoriously demanding. Equipment must perform under extreme conditions—heat, dust, vibration, and remote locations—making machinery prone to wear and tear. Unexpected breakdowns can lead to massive downtime, lost productivity, and increased operational costs. Traditional maintenance models—reactive or scheduled—often fall short of addressing these challenges effectively.
Predictive maintenance, however, offers a smarter solution. By monitoring equipment in real-time using data from embedded sensors, companies can predict when a part is likely to fail and schedule maintenance proactively. This minimizes unnecessary servicing, prevents catastrophic breakdowns, and ensures optimal performance.
Key benefits of predictive maintenance in mining include:
- 1. Increased Equipment Uptime: Reduces unplanned outages.
- 2. Cost Savings: Avoids unnecessary maintenance and parts replacement.
- 3. Safety Enhancements: Prevents accidents due to equipment failure.
- 4. Operational Efficiency: Allows better planning of maintenance schedules.
- 5. Sustainability: Extends the lifecycle of components and reduces waste.
The Collaborative Vision: TU Delft and Hitachi CE
The collaboration between TU Delft and Hitachi CE exemplifies how academia and industry can come together to solve complex engineering challenges. TU Delft, known for its pioneering research in geoscience, aerospace, and engineering, brings theoretical and modeling expertise. HCME contributes practical insights, large-scale datasets, and cutting-edge equipment technology.
- Hydraulic pressure
- Temperature
- Vibration levels
- Load conditions
- Operational hours
This real-world data allows researchers to understand how different components degrade over time under varying conditions. Such empirical evidence is essential for building accurate predictive models.
The ability to track patterns over time enables the detection of anomalies that precede failures. For instance, a slight but consistent increase in hydraulic pressure beyond normal operating levels could indicate wear in a seal or valve that, if not addressed, could lead to a major system failure.
Modeling Component Degradation
Using the vast amount of sensor data, Malihe Goli and her team are creating sophisticated machine learning models capable of predicting component failure. These models learn from historical maintenance logs, sensor measurements, and failure events to understand the typical lifecycle of various components.
The modeling process involves several stages:
1.Data Cleaning and Normalization: Removing noise and outliers to ensure accurate input. 2.Feature Engineering: Identifying the most relevant variables affecting component wear. 3.Model Training: Using algorithms such as neural networks, random forests, and support vector machines 4.Validation and Testing: Comparing predictions against real-world failure events.
- These models are capable of providing actionable insights, such as:
- – Which component is likely to fail soon
- – Estimated remaining useful life (RUL) of a part
- – Optimal timing for ordering replacements
- – Suggested preventive measures to extend component life

Advancing the Future of Mining Through Collaboration and Innovation
The collaboration between Delft University of Technology (TU Delft) and Hitachi Construction Machinery Europe (Hitachi CE) represents a powerful alliance between academia and industry, aimed at transforming the future of mining operations through advanced research and technology development. Mining is a critical global industry that powers numerous sectors but is also faced with complex challenges such as equipment downtime, maintenance costs, and operational inefficiencies.
By focusing on predictive maintenance and data-driven models, this partnership is poised to address these challenges head-on, bringing innovation and sustainability to mining equipment management.At the core of this collaboration is the ambition to develop sophisticated predictive maintenance models that can anticipate equipment failures before they occur.
Mining machinery, including massive excavators, dump trucks, pumps, and brakes, operates under extreme conditions, often in remote locations where unexpected breakdowns can lead to significant downtime and financial loss. By harnessing sensor data collected from these machines — such as temperature, pressure, and vibration readings — the research aims to identify patterns that indicate component degradation. This data-centric approach allows for timely and accurate predictions of when parts need maintenance or replacement, shifting maintenance strategies from reactive to proactive.
Such predictive capabilities not only improve the reliability of heavy mining equipment but also help optimize maintenance schedules, reducing unnecessary downtime and operational disruptions. This means mining companies can plan repairs and parts procurement more effectively, ultimately lowering life-cycle costs and increasing overall equipment availability. Additionally, improved maintenance planning enhances safety by preventing sudden machinery failures that could endanger workers and the environment.
The research led by Malihe Goli at TU Delft, supported by Hitachi CE’s extensive machine data, exemplifies the power of combining theoretical knowledge with practical application. By integrating expertise from TU Delft’s Geo-Resources Section and the Intelligent Sustainable Prognostics Group, the project is well-positioned to develop robust degradation models that adapt to real-world conditions. This multidisciplinary approach ensures that the research outcomes are not only scientifically rigorous but also highly relevant to industry needs.
