What is the Cost of Shaft Maintenance, and How Can It Be Minimized?

Shaft maintenance is a critical part of any underground mining operation. Given that the shaft is the main artery of a mine, supporting personnel transport, ore hoisting, and ventilation, maintaining its integrity is essential. However, the costs associated with shaft maintenance can quickly add up, especially if not carefully managed. In this blog, we’ll dive into the cost of shaft maintenance, the factors that influence these costs, and strategies to minimize maintenance expenses while ensuring operational efficiency and safety.

The Breakdown of Shaft Maintenance Costs

Shaft maintenance costs can be categorized into several areas, each with its own financial implications:

1. Labor Costs

Labor is often one of the largest expenses in shaft maintenance. It includes wages for shaft inspectors, maintenance crews, engineers, and safety personnel. Additionally, the labor required for routine inspections, repairs, and upgrades can be quite extensive, especially when operating in confined or hazardous environments.

2. Materials and Equipment Costs

Shaft maintenance frequently involves the replacement or repair of key materials such as timber, steel supports, hoist ropes, and lining systems. These materials can be costly, and procurement times may lead to increased downtime. Specialized equipment, such as hoisting machinery, inspection tools, or safety equipment, also adds to the cost.

3. Downtime Costs

One of the most significant hidden costs of shaft maintenance is the downtime incurred during inspections, repairs, or upgrades. When a shaft is out of service, the entire mine’s productivity is affected. This results in delays in ore transportation, worker movements, and operational efficiency. Extended downtime can lead to a considerable loss of revenue and resource utilization.

4. Inspection and Monitoring Technology Costs

Advanced technologies like LiDAR 3D scanning, remote monitoring systems, and sensor-based data logging are increasingly used in shaft maintenance. While these tools help improve efficiency and accuracy, they come with initial costs, as well as ongoing maintenance and software updates.

5. Compliance and Regulatory Costs

Mining operations must adhere to safety regulations and standards set by local and international governing bodies. Compliance often requires extensive documentation, third-party audits, and regular safety checks—each of which can lead to added costs.

How Can Shaft Maintenance Costs Be Minimized?

While shaft maintenance is essential, it doesn’t have to be cost-prohibitive. There are several strategies that mining operations can use to minimize the costs associated with shaft upkeep:

1. Implementing Predictive Maintenance

Rather than relying on reactive maintenance—which occurs after problems have already developed—predictive maintenance involves the use of data analytics and monitoring tools to anticipate issues before they become critical. Technologies like IoT sensors, vibration monitoring, and temperature gauges provide real-time data that can help operators identify wear and tear in shaft equipment and infrastructure. This proactive approach reduces emergency repairs and unscheduled downtime, ultimately lowering labor and material costs.

Example: If a monitoring system detects that a hoist rope is wearing unevenly, the maintenance team can replace it before a breakage occurs, preventing costly downtime and repair work.

2. Utilizing 3D Scanning for Inspections

One of the most cost-effective technologies in modern shaft maintenance is LiDAR-based 3D scanning. This technology allows for remote inspections, reducing the need for personnel to enter the shaft, which minimizes both labor and safety costs. 3D scans provide highly accurate models of the shaft, which can be used to track degradation over time, plan maintenance interventions, and avoid unnecessary repairs. This results in fewer physical inspections and better allocation of maintenance resources.

By using digital models, engineers can prioritize areas that require immediate attention, thus reducing unnecessary interventions and optimizing maintenance budgets.

3. Scheduled and Preventive Maintenance

Having a structured maintenance schedule that is based on the actual usage and condition of shaft infrastructure can drastically reduce costs. Regular preventive maintenance, such as routine lubrication, checking hoist mechanisms, reinforcing timbers, and cleaning ventilation systems, ensures that minor issues don’t escalate into expensive major repairs. By setting up a comprehensive asset management plan, operations can better anticipate needs, avoid unexpected failures, and optimize labor.

Example: Regular inspections of shaft supports and timber can help identify small cracks or weaknesses that could lead to larger, more costly structural failures if left unattended.

4. Maximizing Equipment Lifespan

Choosing high-quality materials and equipment and properly maintaining them can extend the lifespan of shaft infrastructure and machinery. Durable hoist systems, corrosion-resistant materials, and high-strength steel components last longer and perform better over time, reducing the frequency of repairs and replacements. Investing in quality upfront may increase initial costs but can yield long-term savings by reducing the frequency and severity of breakdowns.

5. Training and Workforce Efficiency

Investing in proper training for shaft maintenance personnel can greatly improve the efficiency of maintenance tasks and reduce labor costs. A well-trained team can perform inspections, repairs, and safety checks more efficiently, reducing the amount of time spent on each task and minimizing mistakes that could lead to costly errors. Furthermore, a skilled workforce is better equipped to identify potential issues before they escalate.

6. Adopting Automation and Robotics

Advancements in automation and robotic technologies are revolutionizing shaft maintenance. Robotics can perform tasks like routine inspections, repairs, or even cleaning shafts. These technologies can operate 24/7, reduce labor costs, and prevent human errors that could lead to costly downtime. Drones equipped with cameras or LiDAR can conduct comprehensive scans of the shaft, providing valuable data without putting personnel at risk or in harm’s way.
