How to design a mining asset repair and maintenance workflow

The mining industry is characterized by the intensive use of machinery and equipment, which are subject to constant wear and tear due to extreme working conditions. To ensure safety and operational efficiency, it is essential to implement a well-defined mining asset repair and maintenance workflow .

In this blog post, we'll walk you through the basics of designing an effective repair and maintenance workflow, taking into account industry best practices.

1. Identify critical assets

The first step is to identify mining assets that are critical to the operation. These assets are typically those that, if they fail, could have a significant impact on production, safety, or the environment.

To identify critical assets, various criteria can be used, such as:

Impact on production: How large would the production loss be if the asset failed?
Safety: Could asset failure put workers' safety at risk?
Repair cost: How much would it cost to repair or replace the asset if it failed?
Environmental impact: Could asset failure cause environmental damage?

Once critical assets have been identified, their maintenance must be prioritized based on their importance.

2. Establish a preventive maintenance program

A preventive maintenance program is an essential strategy for preventing failures in mining assets. This program should include inspection, lubrication, adjustment, and component replacement, performed periodically according to the manufacturer's recommendations or based on experience.

By implementing a preventive maintenance program, unplanned failures can be significantly reduced, resulting in greater asset availability, lower repair costs, and improved operational safety.

3. Implement an integrated EMS with suppliers.

A maintenance management system (MMS) is a fundamental tool for organizing and managing repair and maintenance activities for mining assets. The MMS provides basic internal tracking of asset management; however , advanced solutions now also exist that integrate with maintenance providers . This type of tool allows for:

Plan and schedule maintenance tasks
Record the maintenance history of each asset
Monitor asset status and detect potential failures
Track the external repair process
Predict when an asset will be back in operation at the plant
Work in an integrated manner with a network of suppliers
Generate reports and data analysis

Implementing an EMS can help improve the efficiency and effectiveness of the maintenance program, resulting in lower operating costs and increased asset reliability, as well as a strengthened repair chain.

4. Train the maintenance team

The team involved in the comprehensive maintenance cycle must be trained to perform repair, maintenance, and digitalization tasks safely and efficiently. Training should include:

Knowledge of basic maintenance principles
Specific procedures for each type of asset
Occupational health and safety standards
Using technological tools to monitor your work

Well-trained maintenance personnel are essential to ensuring the quality and effectiveness of repair and maintenance activities.

5. Monitor and continuously improve the maintenance flow

The repair and maintenance workflow must be continuously monitored and improved to ensure its effectiveness. This involves more than just the maintenance work itself; it involves a number of key players involved in every part of the process, including external repairers. This can be achieved by:

Analysis of maintenance data
Identification of opportunities for improvement
Implementation of changes and improvements
Dedicated expert support

A well-designed and managed maintenance workflow can significantly contribute to the safety, efficiency, and profitability of a mining operation. Furthermore, it is key to have external input and expert advice that can contribute to the continuous improvement of this process.

6 Trends That Will Redefine Supply Chain and Maintenance in 2026

Fun fact: our article on trends for 2025 was the most-read post in the history of our blog. Apparently, no one likes to navigate blindly (and we all love a good spoiler about what's to come). So, by popular demand, we're doubling down.

If you work in mining, you know that 2026 isn't just another year of "doing the same thing, but a little faster." The industry is definitely moving from a period of stabilization to an era of intelligent execution.

We analyze the most dense reports in the industry (those from McKinsey, Deloitte, and EY that you can't be bothered to read on a Friday) and filter out the noise to leave you with only the signal.

Here are the real trends that will set the tone in Supply Chain and Asset Management. No unnecessary technicalities.

From the High Andes, Lundin Mining adds Aisoncore in Caserones

At more than 4,000 meters above sea level, where decisions weigh as much as trucks, and the margin for error shrinks along with oxygen, Caserones has decided to bet on the future. Lundin Mining has made official the launching of Aisoncore at its acquired site in 2023. The platform, which has been operating successfully at Candelaria for almost two years, thus makes a leap in scale, complexity and confidence.

But this story does not start on the mountain. It starts with a relationship built by hand, repair after repair.

Mining Supply Chain and Maintenance Outlook 2025: Interview with Patricio Valencia of Lunding Mining

One of the industries that has undergone the most transformations in recent years is mining. These changes, both strategic (mergers, discoveries, explorations) and internal (processes and technological innovation), have given rise to "mining 4.0", where all areas are connected and have a significant impact.

At Aisoncore, we have observed that Maintenance and Supply Chain have become key players in this transformation, either with strategies that drive operational efficiency and promote the circular economy. To discuss this and to know what will mark this 2025 we wanted to talk to one of our clients, Patricio Valencia who is Assistant Manager of Purchasing and Materials Engineering at Lunding Mining Chile.

Is the PO Delivery Date a good estimator of when a repairable will return?

In the mining industry, it is common for suppliers to provide estimated delivery dates when generating the purchase order (PO) that later turn out to be unrealistic. Often, the committed date in ERP systems (e.g. SAP) does not reflect the actual start of work, but only a theoretical commitment from the supplier. The result: promised dates remain "in the past" long before actual delivery occurs, leaving purchase orders with expired deadlines in the system.

Promoting transparency in mining supply chains and maintenance with technology.

Within the mining industry, which today plays a fundamental role in the global economy, maintenance is a critical function that ensures operational continuity and equipment efficiency. Supply chain transparency, an increasingly important concept in various industries, is also gaining relevance in this area, especially with regard to the sourcing of spare parts and the selection of maintenance service providers.

The adoption of transparent practices, greatly facilitated by technological advances, is becoming a key factor in building stakeholder trust, ensuring ethical practices, and fostering sustainable development within the mining industry. But what is it all about, and how do we see it reflected in practice? Read on to learn more.
