Mining is one of the most inspection-intensive industries on earth. The combination of extreme mechanical loading, abrasive and corrosive environments, high-consequence failure modes, and a dense web of statutory obligations means that inspection is not a discretionary activity in mining — it is a fundamental operational requirement. A dragline bucket-rigging failure, a winding rope incident, a tailings dam breach, or a pressure vessel rupture in a processing plant can be catastrophic. The inspection records that sit between normal operation and disaster must be complete, current, and immediately accessible.
For the inspection bodies and mining quality assurance teams that manage this workload — and for the mineral testing laboratories that support resource characterisation, ore processing control, and environmental compliance — the data management challenge is significant. This article covers the full scope of inspection in the mining sector: what requires inspection, what the regulatory framework looks like, how NDT fits in, what mineral testing laboratories manage, and how purpose-built mining inspection software addresses the records challenge.
Inspection in the Mining Industry
Mining inspection spans a broader range of asset types, hazard categories, and technical disciplines than almost any other industrial sector. At an open cut operation, the inspection scope includes mobile mining fleet (rigid and articulated dump trucks, hydraulic excavators, front-end loaders, rotary drill rigs), fixed plant (crushers, screens, conveyors, pumps, thickeners), structures (pit walls, haul roads, berms, tailings storage facilities), services infrastructure (high-voltage electrical systems, compressed air, water supply, fuel), and environmental monitoring systems (groundwater bores, dust monitors, water quality sampling points). At an underground mine, the scope extends to ground support systems (rock bolts, mesh, shotcrete), ventilation infrastructure (fans, doors, regulators), winding systems (hoists, ropes, cages), and underground mobile equipment operating in confined and potentially hazardous atmospheres.
Who Conducts Mining Inspections
Mining inspection is conducted by several different categories of organisation, often working simultaneously on the same site. The mine's own maintenance and engineering teams conduct pre-start checks, routine maintenance inspections, and statutory pre-shift inspections of equipment such as mobile plant. Original equipment manufacturer (OEM) service organisations conduct major scheduled services, warranty-related inspections, and component rebuild inspections. Independent inspection bodies — accredited to ISO/IEC 17020, or operating under competency frameworks recognised by the relevant state regulator — conduct statutory inspections of registered plant, NDT inspections of critical components, and third-party audits of safety management systems. Specialist geotechnical and dam safety consultants conduct structural inspections of pit walls, underground openings, and tailings storage facilities. Environmental consultants and NATA-accredited laboratories conduct sampling and testing for environmental compliance.
Consequence of Inspection Failure
The consequences of inspection system failure in mining are severe. Regulatory consequences include prosecution under state mining legislation, mine closure orders, and significant financial penalties. Operational consequences include unplanned equipment downtime, which at a large open cut mine operating 30-tonne haulage trucks can cost hundreds of thousands of dollars per day. Safety consequences — the most serious — include fatalities and catastrophic asset failures. The mining industry's inspection obligations exist precisely because these consequences are real and have been realised in incidents across the sector globally.
Regulatory Framework
Australian mining inspection is regulated through a combination of federal and state legislation, supported by a framework of Australian and international standards. The regulatory landscape is fragmented by state jurisdiction, with significant variation between coal and non-coal operations, and between underground and open cut environments.
Safe Work Australia and the Model WHS Laws
Safe Work Australia develops the model Work Health and Safety (WHS) laws, which have been adopted (with variations) by most Australian states and territories. The WHS Regulations include specific provisions for plant and structures — defining registration requirements for certain categories of plant above defined risk thresholds, and imposing duties on designers, manufacturers, importers, suppliers, and operators of plant. Under the model WHS Regulations, pressure equipment, cranes and hoists, winding equipment, and several other categories of plant above defined pressure-volume or Safe Work Load thresholds require both design registration and plant item registration with the relevant state or territory regulator.
State Mining Regulators
Each major mining state has its own dedicated mining regulator with jurisdiction over mine safety and statutory inspection requirements:
- NSW Resources Regulator administers the Work Health and Safety (Mines and Petroleum Sites) Act 2013 and the Work Health and Safety (Mines and Petroleum Sites) Regulation 2022. The NSW Resources Regulator enforces statutory inspection requirements for coal mines, metalliferous mines, and petroleum sites, and approves competent persons to conduct statutory inspections.
- Resources Safety & Health Queensland (RSHQ) administers the Coal Mining Safety and Health Act 1999, the Mining and Quarrying Safety and Health Act 1999, and associated regulations. Queensland's framework is notable for its separate treatment of coal and non-coal operations, and its use of site senior executives and statutory position holders with defined inspection obligations.
- Department of Mines, Industry Regulation and Safety (DMIRS), Western Australia administers the Mines Safety and Inspection Act 1994 and the Mines Safety and Inspection Regulations 1995. WA regulations include specific requirements for winding plant, man-riding equipment, and hazardous areas in underground mines.
- SA Resources (South Australia) and equivalent bodies in the Northern Territory, Tasmania, and Victoria administer jurisdiction-specific requirements for their respective mining sectors.
Key Australian and International Standards
The technical requirements for mining inspection are defined in a framework of Australian Standards, joint Australian/New Zealand Standards, and international standards:
| Standard | Scope |
|---|---|
| AS/NZS 3788 | Pressure equipment — In-service inspection |
| AS 3873 | Pressure equipment — Operation and maintenance |
| AS 4343 | Pressure equipment — Hazard levels |
| AS 2550 series | Cranes, hoists and winches — Safe use |
| AS 3569 | Steel wire ropes — Product specification (including winding ropes) |
| AS 1418 series | Cranes, hoists and winches — Design, manufacture and performance |
| AS 1085.17 | Railway track material — Rail anchors |
| AS/NZS 4024 series | Safety of machinery |
| IEC 60079 series | Explosive atmospheres — Equipment protection (hazardous areas classification and Ex equipment inspection in underground mines and surface explosive handling areas) |
| AS/NZS 60079.17 | Explosive atmospheres — Inspection and maintenance of electrical installations in classified areas |
| ANCOLD Guidelines on Tailings Dams | Tailings storage facility design, inspection, and dam safety surveillance |
| AS 1085.17 / AS 3995 | Design of steel lattice towers and masts (relevant to mine headframes) |
Hazardous areas in mining — particularly underground operations where methane or coal dust creates explosive atmospheres, and surface areas where blasting agents or fuel vapours create classified zones — are subject to IEC 60079 series requirements. Ex-rated electrical equipment in these areas must be inspected and maintained in accordance with AS/NZS 60079.17, with records maintained for each item of Ex equipment. The inspection categories under this standard (visual, close, detailed) and the intervals at which each category applies must be documented in the inspection schedule.
Mining Equipment Inspection
The scale and diversity of mining equipment creates an inspection management challenge that few other industries match. A large open cut operation may have hundreds of individual plant items subject to statutory inspection obligations, thousands of mobile equipment pre-start inspections per day, and dozens of specialist NDT and condition monitoring programmes running simultaneously.
Mobile Plant
Mobile mining plant — rigid dump trucks, articulated trucks, hydraulic face shovels, rope shovels, front-end loaders, graders, dozers, water carts, and rotary drill rigs — represents the largest category of equipment by unit count at most open cut operations. Pre-start inspections are conducted by operators at the beginning of each shift, with findings recorded in a defect book or digital pre-start system. Defects that present an immediate safety risk must be quarantined and rectified before the machine enters service. Scheduled maintenance inspections — at defined engine hours or calendar intervals — are conducted by the mine's maintenance team or OEM service personnel. These inspections generate detailed records of component condition, oil analysis results, wear measurements, and rectification work performed.
Mine site inspection software must be able to capture pre-start inspection records by equipment tag, track defects from identification through to rectification and sign-off, and maintain the full maintenance history of each unit. For large fleets operating on multiple shifts, real-time visibility of equipment status — which units are in service, which are on defect hold, which are due for scheduled service — is operationally critical.
Fixed Plant — Conveyors, Crushers, and Processing Equipment
Conveyor systems at mining operations range from short in-pit conveyors to long-distance overland systems carrying ore or product hundreds of kilometres. Conveyor inspection covers structural steelwork (frames, bents, take-up towers), drive systems (gearboxes, motors, couplings), belt condition (splice integrity, belt damage, tracking), idler condition, and take-up and tensioning systems. Conveyor inspection records must capture inspection findings by conveyor segment and component type, with photographic evidence of defects and a clear record of rectification status.
Crushers — primary, secondary, and tertiary — and screening equipment experience severe mechanical loading and are subject to wear that must be monitored to prevent catastrophic failure. Mill liners in SAG mills, AG mills, and ball mills are inspected by visual and measurement methods to track wear progression and plan relining shutdowns. Slurry pumps, thickeners, and flotation cells in processing plants require regular inspection of wear components, seals, and structural elements.
Lifting Equipment — Cranes, Hoists, and Winding Equipment
Lifting equipment in mining includes overhead and portal cranes in workshops and processing plants, mobile cranes used for maintenance work and construction, and underground hoists used to raise and lower personnel, equipment, and ore (also called man-riding equipment or conveyances). All lifting equipment above defined safe working load thresholds is registered plant under WHS regulations, requiring periodic inspection at intervals set by AS 2550 and the individual inspection schedule for each item.
Winding equipment — the hoists used to raise and lower cages and skips in underground mines — is subject to particularly rigorous statutory inspection requirements under state mining regulations. In most jurisdictions, winding plant must be inspected by a competent person (typically holding specific winding plant inspector qualifications recognised by the state regulator) at defined intervals. The winding ropes themselves require periodic electromagnetic rope testing (EMRT) and visual inspection at intervals specified by the relevant regulation and by AS 3569.
Pressure Equipment — Compressors, Vessels, and Pipework
Open cut and underground mines rely on extensive compressed air systems for pneumatic tools, drill rigs, and underground ventilation controls. The compressors, air receivers, pressure pipework, and associated fittings above defined pressure-volume thresholds are registered plant items requiring periodic inspection under AS/NZS 3788. Inspection records must reference the design registration number and plant registration number for each item, document inspection findings and the basis for the next inspection interval, and record the inspector's competency and authorisation.
Processing plants in mineral operations also contain a wide range of pressure vessels — autoclave reactors in gold processing operations, pressure oxidation (POX) vessels, and various process vessels operating at elevated temperature and pressure. These require inspection programmes designed around AS/NZS 3788 hazard levels and the specific service conditions of the vessel.
Electrical Equipment Inspection
High-voltage electrical infrastructure at mine sites — including switchrooms, transformers, trailing cables on mobile equipment, and underground power distribution systems — requires periodic inspection and testing. Underground coal mines and other operations with explosive atmosphere classifications require Ex equipment inspection under AS/NZS 60079.17, with inspection records for each item of certified Ex equipment maintained in an Ex equipment register. The register must capture the equipment's type of protection (e.g., Ex d, Ex e, Ex i), Ex certificate number, IP rating, inspection category, inspection interval, and the dates and findings of each inspection.
Structural and Geotechnical Inspection
Mining operations create and depend on large-scale engineered structures — open pit walls, underground excavations, tailings storage facilities, heap leach pads, and surface infrastructure — whose stability is fundamental to safe operation. Structural and geotechnical inspection in mining is a specialist discipline that sits alongside conventional equipment inspection but has its own methods, standards, and regulatory framework.
Open Pit Wall and Highwall Inspection
Open pit highwall stability is critical for safe mining operations. Geotechnical monitoring programmes — using slope stability radar (SSR), total station survey prisms, extensometers, inclinometers, and piezometers — generate continuous streams of monitoring data that must be assessed against movement trigger levels. Geotechnical inspections by qualified geotechnical engineers document visible features including tension cracks, water seepage, rock mass conditions, and bench geometry. Inspection findings must be recorded with sufficient spatial referencing to allow trend analysis over time, and must be escalated when trigger levels are exceeded.
Underground operations require inspection of ground support — rock bolts, mesh, shotcrete, timber sets, and cable bolts — in active headings and access ways. Ground support inspection records must document installation quality, any identified failures or deterioration, and remediation actions. Changes in ground conditions — new cracking, changes in water inflow, seismic events — must trigger re-inspection and re-assessment.
Tailings Storage Facility Inspection
Tailings storage facilities (TSFs) are among the highest-consequence structures in the mining industry. The failures at Brumadinho (Brazil, 2019, 270 fatalities) and Mount Polley (Canada, 2014) — along with many earlier events — have driven a global tightening of TSF inspection and surveillance requirements. In Australia, the ANCOLD Guidelines on Tailings Dams provide the primary framework for TSF inspection frequency and content, supplemented by state regulator requirements.
A TSF inspection programme typically includes surveillance inspections by mine site personnel at intervals of monthly to quarterly (depending on hazard category and operational phase), formal inspection by a suitably qualified professional — typically a geotechnical engineer with dam safety experience — at least annually, and a formal dam safety review by a qualified independent reviewer at intervals of typically three to five years. Records from TSF inspections must capture embankment condition (cracking, seepage, sloughing, animal burrowing), instrumentation readings (piezometer levels, settlement markers, inclinometers), freeboard measurement, spillway condition, and any observed changes since the previous inspection. Emergency action plans and operations manuals must be kept current and accessible.
Heap Leach Pad Inspection
Heap leach facilities — used in gold, copper, and uranium processing — involve liner systems, drainage layers, and solution ponds that require regular inspection for liner integrity, solution containment, and pad stability. Liner inspection records must document any identified punctures, seams, or drainage anomalies, with GPS-referenced locations to enable repair and trend tracking. Solution containment records — volumes of pregnant solution, barren solution, and raffinate — must be maintained for environmental compliance.
NDT in Mining
Non-destructive testing in mining addresses a specific challenge: mining equipment operates in some of the most mechanically demanding environments of any industry. Abrasion, impact, corrosion, fatigue, and thermal cycling combine to cause degradation that is often not visible without specialist inspection techniques. The consequences of undetected defects — bucket rigging failures on a large dragline, rope breaks on a winding system, pipe failures on a high-pressure slurry line — are severe. NDT programmes in mining are designed to detect these defects before they cause failure.
Ultrasonic Thickness Measurement on Slurry Pipelines and Processing Equipment
Slurry pipelines carrying ore slurry, tailings, or process reagents experience continuous abrasive wall loss. Ultrasonic thickness measurement (UTM) programmes — typically using digital UT thickness gauges with data logging capability — map wall thickness at defined measurement points along pipelines and on process equipment such as pump casings, thickener tanks, and cyclone clusters. Readings are compared against minimum acceptable wall thickness values (typically derived from pressure design calculations using AS 4041 or ASME B31.3), and trend data is used to predict remaining life and plan replacement before failure.
UTM records in mining are high-volume — a single slurry pipeline survey may generate thousands of thickness readings — and must be managed to allow trend analysis over multiple inspection cycles. Mining NDT software must support grid-based thickness mapping, trend charting, and minimum thickness flagging across large datasets.
Magnetic Particle and Penetrant Inspection of Dragline Components and Ground Engaging Tools
Draglines — the massive walking excavators used in coal mining to strip overburden — are among the largest machines operated anywhere in industry. Their structural components — the mast, A-frame, boom, and bucket rigging — are subject to enormous cyclic loading and must be regularly inspected for fatigue cracking. Magnetic particle inspection (MPI) is the primary surface and near-surface crack detection method for these ferrous components. MPI records must document the specific components inspected, the technique applied (wet fluorescent MPI is typically used for fatigue-sensitive components), calibration of equipment, findings, and disposition of any indications found.
Ground engaging tools (GET) — teeth, adapters, shrouds, and lip assemblies on excavator buckets — are high-wear components that are also subject to cracking under impact loading. MPI and visual inspection of GET components is conducted during change-out cycles. Penetrant testing (PT) is used for similar purposes on non-ferrous components including aluminium alloy parts and some stainless steel process equipment.
Phased Array Ultrasonic Testing of Mill Liners and Critical Welds
Mill liners — the wear-resistant liners fitted inside SAG mills, AG mills, and ball mills — can be inspected using phased array ultrasonic testing (PAUT) to assess liner thickness and detect internal cracking without removing the liner from service. PAUT generates sector scan images that provide significantly more information than conventional single-probe UT, allowing assessment of remaining wear and early detection of developing cracks. The data generated — typically stored as B-scan and sectorial scan images linked to specific liner positions — requires structured records management to support trend analysis and relining planning decisions.
Critical structural welds in processing plant, headframes, conveyor structures, and mill foundations are inspected using PAUT as an alternative or supplement to radiographic testing. PAUT is particularly suited to thick-section welds where conventional film radiography provides inadequate depth resolution.
Electromagnetic Rope Testing of Winding Ropes
Winding ropes — the steel wire ropes used to raise and lower cages and skips in underground mines — are safety-critical components subject to mandatory inspection under state mining regulations. Electromagnetic rope testing (EMRT) uses magnetic flux leakage (MFL) and loss of metallic cross-sectional area (LMA) sensors to detect both internal and external wire breaks and cross-sectional area loss that are not visible to external visual inspection. Most state mining regulations specify the intervals at which EMRT must be conducted and the qualifications required of the testing operator. EMRT records must document the rope identification, test date, LMA and MFL readings, and disposition — including any identified sections requiring discard or close monitoring.
Radiographic Examination of Mining Structures
Industrial radiography using X-ray or gamma-ray sources is used in mining for weld inspection in fabrication and repair of critical structural components — including headframe steelwork, pressure vessel shells, and large bore pipework. Radiographic examination (RT) of welds requires certified Level 2 or Level 3 RT technicians, controlled radiographic sources, and records that include the technique sheet, film or digital image reference, operator details, and interpretation report. The increasing adoption of computed radiography (CR) and digital radiography (DR) in mining contexts is improving image quality, reducing chemical processing requirements, and enabling electronic archival of radiographic records.
Mineral Testing Laboratories
Mineral testing laboratories — whether operated by mining companies as in-house analytical facilities, by independent commercial laboratories, or as specialist geochemistry services within large TIC groups — manage a distinctive blend of sample management, analytical method control, and data reporting requirements. The outputs of these laboratories — assay results, metallurgical test data, coal quality certificates, environmental monitoring results — directly inform production decisions, resource estimation, and regulatory compliance.
Assay Laboratories — Fire Assay, ICP-MS, and XRF
Precious metals mining relies on fire assay as the primary analytical technique for gold and platinum group element determination. Fire assay involves fusing a prepared ore sample with lead oxide and other fluxes at approximately 1000°C, collecting the precious metals in a lead button, and then cupelling the button to remove the lead, leaving a precious metal bead that is weighed or further analysed. Fire assay is one of the oldest analytical techniques in mining and remains the most accurate method for gold at low concentrations.
Inductively coupled plasma mass spectrometry (ICP-MS) provides multi-element analysis at trace and ultra-trace levels, supporting both geochemistry exploration programmes and environmental monitoring. X-ray fluorescence (XRF) — in both wavelength-dispersive (WD-XRF) and energy-dispersive (ED-XRF) configurations — provides rapid major and minor element analysis for ore characterisation and process control. Handheld XRF instruments are widely used at mine sites for on-the-spot material identification and grade scanning, though their results require appropriate qualification when used for resource estimation.
Assay laboratory management software must support sample receipt and chain of custody tracking (including sample condition on receipt, preparation method, and storage location), analytical run management with batch control and certified reference material (CRM) tracking, results entry with QA/QC data assessment, and report generation. NATA accreditation to ISO/IEC 17025 is the standard expectation for commercial assay laboratories in Australia; in-house mining company laboratories increasingly also seek accreditation as a basis for confidence in their data quality.
Metallurgical Testing — Comminution, Flotation, and Leach Testing
Metallurgical testing laboratories conduct the bench-scale and pilot-scale tests that inform processing plant design, optimisation, and troubleshooting. Comminution testing — including Bond Ball Mill Work Index (BWi) tests, SAG Mill Comminution (SMC) tests, and Drop Weight Index (DWi) tests — characterises ore hardness and grinding behaviour. Flotation testing determines recoveries, concentrate grades, and reagent requirements for sulphide mineral processing. Heap leach column tests and bottle roll tests characterise gold and copper recovery from oxide and transitional ores.
Metallurgical test data management requires structured records linking each test to a specific sample, its ore type and location within the deposit, the test method and equipment used (with calibration status), and the results with associated quality control data. For metallurgical test results to be used in resource and reserve estimates or feasibility studies, the data chain from sample collection to test result must be fully traceable and reproducible.
Coal Quality Testing — Proximate Analysis, Ultimate Analysis, and Calorific Value
Coal quality testing is the lifeblood of the coal supply chain. Thermal and metallurgical coal is traded against quality specifications — calorific value (CV), total moisture (TM), inherent moisture (IM), ash content, volatile matter (VM), fixed carbon (FC), total sulphur, and other parameters — that determine the price paid and the suitability of a parcel for a particular end use. Coal quality testing is typically conducted to AS 4264 (coal sampling) and a suite of AS/NZS 1038 analytical methods.
Ultimate analysis — determining carbon, hydrogen, nitrogen, sulphur, and oxygen content — is required for coal export quality specifications and for calculating combustion characteristics. Coking coal quality specifications additionally include fluidity (Gieseler plastometer), swelling index (crucible swelling number), and reflectance (vitrinite reflectance) testing. Mineral testing lab software must support the full suite of coal quality parameters, coal preparation test data (float-sink washability analysis), and the generation of quality certificates that meet the format requirements of coal export contracts.
Environmental Laboratory Services for Mine Sites
Mine sites generate ongoing environmental monitoring obligations that require laboratory analysis. Water quality monitoring — of surface water, groundwater, process water, and discharge water — covers pH, conductivity, dissolved metals, suspended solids, nutrients, and specific contaminants of concern (including acid mine drainage parameters such as acidity, sulphate, and heavy metals). Soil contamination assessment following spills or legacy impacts requires soil sampling and analysis for petroleum hydrocarbons, heavy metals, and other site-specific contaminants. Dust monitoring — using high-volume air samplers, passive dust deposition gauges, or continuous real-time optical sensors — supports compliance with dust emissions licence conditions and occupational health monitoring of airborne particulates including respirable silica and coal dust.
Environmental laboratory records for mine sites must be maintained to support regulatory reporting — to state environment departments, mine safety regulators, and water authorities — with data traceability from sample collection through analysis to reported result. Chain of custody documentation, sample preservation requirements, hold times, and method detection limits are critical elements of defensible environmental data for regulatory purposes.
Managing Mining Inspection Records with Software
The data management challenge in mining inspection is one of volume, diversity, and consequence. The volume comes from the sheer number of assets, inspections, and analytical results generated at a mine site. The diversity comes from the range of asset types, inspection methods, and laboratory techniques involved. The consequence comes from the fact that these records are not administrative overhead — they are the evidence base for safety decisions, regulatory compliance, and commercial transactions.
Equipment Registers and Asset Data
OMS provides a structured asset register that supports the full range of mining plant items — from registered pressure vessels and cranes through to mobile plant, conveyor systems, and environmental monitoring equipment. Each asset record carries its unique identifier, technical specifications, registration details (design registration number, plant registration number, hazard level), current inspection status, and full inspection history. Assets can be grouped by site, by area, by asset class, or by responsible authority — supporting both mine site management and the inspection body's multi-client asset management.
For inspection bodies managing statutory inspection programmes across multiple mine sites and multiple clients, the ability to maintain separate but consistently structured asset registers for each client is essential. OMS's client and site structure supports this without requiring duplicate data entry or manual management of site-by-site spreadsheets.
Inspection Job Scheduling and Dispatch
Mining inspection programmes are typically driven by a combination of fixed-calendar obligations (statutory inspection intervals, regulatory requirements), condition-based triggers (NDT findings that require follow-up at reduced intervals), and operational events (plant modifications, incident investigations, scheduled shutdowns). OMS supports scheduling of inspection jobs against asset-level due dates, with automated alerts as due dates approach and overdue tracking that prevents compliance gaps from going unnoticed.
For mine site inspection teams managing inspection across a large asset base, the ability to schedule and dispatch inspection jobs to specific technicians — with visibility of each technician's current workload, qualifications, and site access — is a significant operational efficiency gain. Inspection job management in OMS covers job creation, technician assignment, field data capture, findings recording, non-conformance raising, and report generation in a single workflow.
NDT Records Management
NDT records in mining are technically demanding — UT thickness grids, EMRT rope scan data, PAUT sector scans, and MPI inspection reports all require structured storage that supports both the raw data and the interpretation report. OMS supports attachment of NDT data files, images, and reports to individual inspection records, with linkage to the specific asset, component, and location within the asset. This allows trend analysis across multiple inspection cycles — comparing wall thickness readings from successive UTM surveys, for example, or tracking the propagation of an identified crack indication over time.
NDT technician certification records — PCN, ASNT, or CSWIP qualifications by method and level, with expiry dates — are maintained in OMS's personnel qualification register. The system prevents assignment of NDT work to technicians whose qualifications have expired or who are not certified for the required method and level, providing an automated competency gate that reduces the risk of unqualified work being performed on safety-critical mining equipment.
Mine Site Asset Registers and Client Reporting
For inspection bodies providing statutory inspection services to mining companies, client reporting is a critical output. Mine site operators need to see, at a glance, which of their registered plant items are currently compliant, which have inspections due within the next 30 or 60 days, and which are overdue. OMS's client portal provides mine site clients with real-time visibility of their asset inspection status — reducing the administrative burden of status enquiries on the inspection body and improving client confidence in the inspection programme.
For larger mine sites with complex multi-contractor inspection arrangements, OMS supports the generation of site-level inspection status reports that can be shared with the mine's safety management system, the relevant state regulator, or corporate safety reporting chains. Report templates can be configured to meet the specific format requirements of individual mine site clients or regulatory bodies.
Non-Conformance and Corrective Action Management
Mining inspection findings that reveal non-conforming conditions — equipment defects, structural anomalies, compliance failures — require formal management through a non-conformance and corrective action (CAPA) process. OMS captures non-conformances raised during inspection, assigns them to responsible parties, tracks corrective actions through to close-out, and maintains an auditable record of the full non-conformance lifecycle. For inspection bodies operating under ISO/IEC 17020 accreditation, and for mining company QA teams maintaining ISO 9001 or ISO 45001 certification, this structured non-conformance management is a core quality system requirement.
Mineral Testing Laboratory Management
For mineral testing laboratories — whether in-house or commercial — OMS provides the core LIMS functionality required to manage the sample-to-report workflow: sample receipt and registration with chain of custody documentation, analytical method assignment, batch and run management, QA/QC data assessment (including CRM performance, duplicate precision, and blank control), results review and authorisation, and report generation and dispatch. The system supports NATA accreditation requirements under ISO/IEC 17025 — including document control, equipment calibration management, internal audit scheduling, and non-conformance management.
Frequently Asked Questions
- What statutory inspections are required for mining equipment in Australia?
- Under the Work Health and Safety Regulations and state-based mining legislation, a wide range of mining plant items require statutory inspection at defined intervals. Registered plant items — including pressure vessels, compressors, pressure pipework, cranes, hoists, winding equipment, and man-riding conveyances — require periodic inspection by a competent person with results recorded against the registered plant item. State-specific requirements apply: in Queensland, the Coal Mining Safety and Health Act 1999 and the Mining and Quarrying Safety and Health Act 1999 prescribe inspection obligations for underground and open cut operations respectively. In New South Wales, the Work Health and Safety (Mines and Petroleum Sites) Act 2013 and its Regulation set requirements. In Western Australia, the Mines Safety and Inspection Act 1994 and associated regulations govern. Mobile plant — trucks, loaders, drills, and excavators — must be inspected and maintained in accordance with manufacturer specifications and site safety management systems. Winding equipment and man-riding cages in underground mines require particularly rigorous statutory inspection under relevant state regulations.
- What NDT methods are most commonly used in mining?
- Mining operations use a broad range of non-destructive testing methods depending on the component being inspected. Ultrasonic thickness measurement (UT) is extensively used on slurry pipelines, processing plant vessels, and wear-critical surfaces to monitor wall loss. Magnetic particle inspection (MPI) is used on dragline components, ground engaging tools, wire rope terminations, and structural welds to detect surface and near-surface cracks. Dye penetrant testing (PT) is used on non-ferrous components and where MPI is impractical. Phased array ultrasonic testing (PAUT) is increasingly used on mill liners, grinding media systems, and critical structural welds. Electromagnetic rope testing (EMRT) is mandatory for winding ropes and friction winder ropes under most state mining regulations, conducted at defined intervals. Visual inspection (VT) remains the most frequently performed method, covering equipment condition, corrosion, damage, and pre-start checks. Eddy current testing is used on some heat exchanger tubes and electrically conductive components in processing plants.
- What is a tailings storage facility inspection and how often is it required?
- A tailings storage facility (TSF) — also called a tailings dam or tailings storage facility — is the engineered structure used to contain the waste material (tailings) produced by mineral processing. TSF inspection is one of the most critical safety obligations in the mining industry because TSF failures can be catastrophic, as demonstrated by the Brumadinho and Samarco disasters in Brazil. In Australia, the Australian National Committee on Large Dams (ANCOLD) Guidelines on Tailings Dams provide the primary technical framework for TSF inspection and monitoring. Annual independent dam safety reviews are required for significant facilities, with more frequent surveillance inspections conducted by the mine's own personnel — typically monthly or quarterly depending on hazard category. After significant rainfall events, staged raises, or seismic activity, additional inspections are triggered. State regulators — including the NSW Resources Regulator, WA Department of Mines, Industry Regulation and Safety, and Queensland Department of Resources — impose specific reporting and inspection obligations. Records must document dam safety monitoring data, seepage readings, piezometer data, survey monitoring of embankment movement, visual inspection findings, and corrective actions.
- What records must mining companies keep for equipment inspection?
- Mining companies are required to maintain comprehensive records across multiple categories. For registered plant items (pressure equipment, cranes, hoists, winding equipment), records must include design registration numbers, plant registration numbers, inspection history with dates and inspector details, findings and rectifications, and next inspection due dates. For mobile plant, pre-start inspection records, defect registers, maintenance records, and operator competency records must be maintained. For structures including tailings storage facilities, pit walls, and underground supports, monitoring data, inspection reports, and geotechnical reports must be retained. For NDT inspections, records must include the method and technique used, equipment calibration details, technician qualification and certification level, inspection results, and any corrective actions. For hazardous areas equipment (IEC 60079 classified zones), Ex equipment inspection records must be maintained including the equipment's Ex certificate number, inspection category, inspection interval, and findings. Most state mining regulations require records to be kept for a minimum of five years, and in some cases for the life of the mine plus a defined period after closure.
- How can inspection software help mining operations manage compliance?
- Mining inspection software provides structured management of the full compliance cycle — from equipment registration and inspection scheduling through to record-keeping, reporting, and corrective action tracking. Key benefits include: automated alerts when statutory inspections or registrations are due, preventing overdue inspections from being overlooked; a searchable asset register linking each piece of equipment to its full inspection history; digital capture of inspection findings in the field, eliminating transcription errors from paper forms; technician qualification tracking that prevents unqualified personnel from being assigned to work they are not certified to perform; audit-ready records that can be produced immediately for regulator inspections; and client reporting that provides mine site operators with real-time visibility of inspection status across their asset base. For inspection bodies operating across multiple mine sites, centralised job management and technician dispatch is a significant operational efficiency gain. For in-house mining company QA teams, the software provides the structured registers, non-conformance management, and CAPA tracking required to maintain management system certification.
