Stock the mining spare parts that are most likely to interrupt production, wear out predictably, or take the longest to replace. For most operations, that means prioritizing equipment-specific wear parts, filters and service items, belts and conveyor components, seals and bearings, hydraulic parts, and selected electrical components. Keep large, expensive assemblies in stock only when downtime exposure, repair options, and supplier lead time justify the investment.
The right inventory depends on your machines, operating conditions, maintenance plan, and supply routes; there is no universal parts list. At Voight Song, we recommend building a critical-spares plan from equipment records and failure history rather than ordering by category alone. The framework below helps maintenance and purchasing teams identify what to stock, what to monitor, and what to source as needed.
Wear parts are often strong inventory candidates because they are exposed to abrasion, impact, or repeated material contact. Depending on your equipment, this category can include bucket teeth and adapters, cutting edges, crusher liners, screens, and other machine-specific contact parts. Stock the designs and sizes that match your actual fleet, since fit and material selection vary by application.
Consumption can change with material characteristics, operating practices, and machine duty. Use issue records and inspection findings to distinguish frequently replaced items from parts that only appear important in a general catalogue. For critical wear components, keep enough to support planned maintenance and a reasonable replenishment interval rather than assuming a single quantity suits every site.
Keep the filters and service parts specified for your machines’ maintenance schedules. This may include engine, fuel, oil, hydraulic, air, and transmission filters, along with items such as gaskets or service kits where applicable. Missing a low-cost service item can delay planned work, so these parts deserve attention even when their unit value is modest.
Verify the exact machine variant and filter specification before purchasing. Similar-looking parts may not be interchangeable, and substitutions should be checked against equipment documentation or qualified technical guidance. Store filters in a clean, dry environment and manage packaging so that parts remain identifiable and protected until use.
For operations that rely on conveyors, consider stocking belt fasteners, idlers or rollers, bearings, pulley lagging, and selected belt sections or repair materials. The right list depends on conveyor design, dimensions, loading conditions, and the availability of local repair services. Focus first on components whose failure could interrupt a key transfer point or prevent safe operation.
Do not assume that a generic conveyor part will fit every installation. Record dimensions, connection details, material requirements, and equipment references where relevant. For belts and other bulky items, assess storage conditions and handling requirements before purchasing spare lengths.
Bearings and seals are common candidates for controlled stock because they support rotating equipment such as pumps, motors, gearboxes, and crushers. Include the correct sizes and configurations for identified critical assets, along with associated components that maintenance teams routinely replace during a repair. Protect these parts from contamination and moisture, and keep identification details with the stock.
Rather than stocking every bearing or seal used across the site, prioritize items that serve critical machines, have documented consumption, or are difficult to source quickly. Confirm interchangeability before consolidating variants. A wrong fit can turn an apparently available spare into a delay.
Depending on your equipment, useful hydraulic spares may include hoses, fittings, seals, filters, and selected valves or cylinders. Pneumatic systems may require their own fittings, valves, and service items. Because configurations and pressure requirements differ, match every item to the equipment specification and the intended duty.
Hoses and seals are not universal commodities. Record connection type, size, material, and other relevant specifications, and follow site procedures for safe storage and replacement. Keep a managed list of components whose failure could disable lifting, steering, braking, or other critical functions.
Consider selected fuses, relays, switches, sensors, connectors, and control components when they are specific to critical equipment and have a clear replacement need. Electrical parts can be small and easy to store, but incorrect voltage, connection, or software compatibility can make a spare unusable. Confirm part numbers and configuration details before adding them to inventory.

For complex electronic modules, weigh stock cost against repair, exchange, and supplier support options. Protect sensitive components from unsuitable storage conditions and follow handling instructions. Keep records of machine compatibility and any required setup or programming steps.
For tracked equipment, assess items such as track shoes, rollers, idlers, sprockets, and related hardware according to fleet size, wear trends, and procurement lead time. These parts can be large or costly, so avoid treating the entire undercarriage as a routine shelf-stock category. Instead, identify the individual components that maintenance records show are most likely to need replacement during the planning period.
Start with a list of assets and their parts, then rate each candidate by operational consequence if unavailable, replacement frequency, and replenishment difficulty. A low-cost part can be highly critical if its absence stops a machine, while an expensive assembly may be manageable if it can be repaired quickly or sourced reliably. Include safety and environmental implications in the assessment, and follow your site’s own risk procedures.
Use at least 12 months of issue and maintenance records as a practical starting point when available, then compare the records with planned maintenance and known changes in operating conditions. This period is a planning recommendation, not a guarantee that past usage predicts future demand. For new equipment or incomplete records, consult maintenance staff and the equipment supplier, then review the assumptions as operating history builds.
Ask suppliers for estimated lead time in calendar days, and record whether that estimate includes manufacturing, dispatch, transport, and any required inspection. Compare the full replenishment window with the time your operation can tolerate the part being unavailable. For a critical component with a long or variable lead time, a buffer may be appropriate; for readily available items, frequent replenishment may be more economical.
Set a defined inventory review interval, such as every 30 days, as a starting point for routine monitoring. Adjust it to match your usage rate, delivery reliability, stock value, and maintenance schedule. A review should check on-hand quantity, open purchase orders, reserved parts, part condition, and changes to the fleet or machine configuration.
For assets that run frequently and support a critical production step, prioritize documented wear items, routine service parts, and selected components with difficult replenishment. Coordinate quantities with planned maintenance and the supplier’s delivery information. Make sure stock is available where maintenance teams can identify and issue it accurately.
Where sourcing or repair support is limited, evaluate a broader buffer for parts that are both critical and difficult to obtain. This does not mean buying every possible component. Focus on credible failure modes, confirmed compatibility, and the time required to restore the machine or obtain an alternative.
For assets with available backup capacity or manageable downtime consequences, on-demand sourcing or repair may be more appropriate than holding costly stock. Confirm that the supplier can identify the correct part and provide a realistic delivery estimate before relying on this approach. Document the decision so purchasing and maintenance teams share the same expectation.
A capable aftermarket supplier should be able to help identify parts from equipment information, clarify specifications, and explain available sourcing or customization options. Provide machine make and model, relevant serial or configuration details, part numbers, photographs where useful, and the required quantity. Ask about material and fit details, packaging, minimum order quantities, and estimated lead time before confirming an order.
