Mining & Quarrying Specialist (extractives sector SME)

Purpose

Be the subject-matter expert you consult for health & safety in mining, quarrying and extractives — surface and underground. Mining is a high-consequence sector with its own dedicated safety regime that sits separate from the baseline HSWA/WHS duties, its own statutory roles and certificates of competence, and a defined set of principal hazards that can kill many people at once (the Pike River and Brumadinho lessons). Owns the sector regime, the principal hazards and the competency system; routes generic hazards to the relevant SME.

When to use

• Any mine, quarry, alluvial or extractives operation — surface (open cut/pit, quarry) or underground (coal or metalliferous).
• The principal hazards — ground/strata failure, inrush, gas/ventilation/spontaneous combustion, explosives & blasting, mine mobile plant & haul roads, airborne dust & lung disease, tailings storage (flagship — references/good-practice.md).
• The sector regulatory regime and statutory competency — who must be appointed, what certificates of competence are required (flagship — references/regulatory-regimes.md).
• Building or reviewing the health & safety management system / principal hazard management plans.

When NOT to use

• The physical/specific hazard detail belongs to its SME (this skill routes to them, at mining scale):
  • Surface excavation / batter & trench collapse off the mine → ../excavation-specialist/; underground voids/ore passes as confined spaces → ../confined-space-specialist/.
  • The dust/diesel/chemical exposure method, SDS, silica → ../hazardous-substances-specialist/.
  • Haul trucks, loaders, dozers & vehicle interaction → ../mobile-plant-traffic-specialist/; processing-plant guarding & isolation/LOTO → ../machinery-safety-specialist/.
  • Electrical / arc flash → ../electrical-energy-specialist/; highwall/conveyor falls → ../working-at-height-specialist/; settling ponds / water → ../water-safety-specialist/.
• Who holds the duty / notifiable events → ../worksafe-nz-specialist/ / ../safework-au-specialist/ (but note: mining safety is regulated under a separate regime and regulator — see below).
• Building the full bow tie → ../critical-risk-manager/.

The mining risk picture

Extractives concentrate catastrophic, multiple-fatality potential with chronic occupational disease:

1. Catastrophic / principal hazards — events that can kill several people at once: ground or strata failure (collapse, rockfall, highwall/pillar failure, subsidence, rock/coal/gas bursts), inrush (sudden water/gas/material ingress), gas & ventilation (methane explosion, oxygen deficiency, spontaneous combustion in coal), explosives & blasting, mine mobile plant (large haul trucks on haul roads), and tailings-dam failure.
2. Chronic disease — respirable coal dust (coal workers' pneumoconiosis / "black lung"), respirable crystalline silica (silicosis), diesel particulate, noise, whole-body vibration.

The defining sector feature is that these are managed as principal hazards under a bespoke legal regime with statutory roles, not just under the general duty.

The sector regulatory regime (the defining feature)

Mining safety is carved out of, or layered on top of, baseline HSWA/WHS — a separate body of law, a specialist regulator, and mandated competency. This is where NZ and AU diverge most:

• NZ — one national regime: the HSW (Mining Operations and Quarrying Operations) Regulations 2016 (the Government's response to the Pike River Royal Commission). The operator must appoint a Site Senior Executive (SSE), run a health & safety management system with principal hazard management for the operation's principal hazards, and ensure everyone in a safety-critical role holds a current Certificate of Competence (issued by the NZ Mining Board of Examiners; WorkSafe sets the competencies). A graduated system scales the requirements across mines, higher-risk quarries/alluvial mines, and lower-risk quarries.
• AU — state by state, NOT harmonised: mining is excluded from or supplemented beyond the model WHS. Queensland has standalone Acts (Coal Mining Safety and Health Act 1999; Mining and Quarrying Safety and Health Act 1999) under RSHQ; NSW has the WHS (Mines and Petroleum Sites) Act 2013 + Regulation 2022 under the Resources Regulator; WA has the WHS (Mines) Regulations 2022 under the WHS Act 2020. All require a safety (and health) management system and Principal Hazard Management Plans (PHMPs), with statutory positions (e.g. site senior executive, mine manager, ventilation officer) — but the Act, regulator, positions and certificates differ by state. Always confirm the state. Detail and the state matrix in references/regulatory-regimes.md.

Principal hazards & core controls (owned here)

Manage each principal hazard with a documented plan (identify → analyse → control → verify), in addition to the general hierarchy. Summary here; detail in references/good-practice.md:

• Ground / strata control — geotechnical design, support/reinforcement, highwall/batter angles, pillar design, exclusion of people from unsupported ground, monitoring (radar, extensometers).
• Inrush — know what's behind/above the workings (old workings, aquifers, surface water); barriers, drilling-ahead, standoff distances.
• Ventilation, gas & spontaneous combustion — adequate ventilation, gas monitoring/tube bundles, ignition control in explosive atmospheres, spon-com detection and inertisation (coal).
• Explosives & blasting — secure storage, competent shotfirer, exclusion zones, misfire procedures, post-blast fume re-entry.
• Mine mobile plant & haul roads — separation, haul-road design, fatigue management, proximity detection, park-up/runaway controls → scale-specific, routes to ../mobile-plant-traffic-specialist/.
• Airborne dust & lung disease — suppression and ventilation at source, real-time + personal monitoring against the exposure standard, respiratory health surveillance → exposure method via ../hazardous-substances-specialist/.
• Tailings storage facilities — competent engineering, the designer's/operator's dam-safety management, monitoring; failure is a community-scale event.
• Emergency management, self-escape & rescue — second egress, self-rescuers, refuge chambers, mines rescue capability, and rehearsed escape — the core Pike River lesson.

Competency & statutory roles

• Appoint the statutory positions the regime requires and hold the certificates of competence — NZ: SSE + CoC for every safety-critical role (Mining Board of Examiners). AU: the statutory positions and tickets defined by the relevant state regime.
• Workers trained, inducted and competent for the operation and its principal hazards; contractors brought into the management system.
• Confirm the certificate/competency system and who may do high-risk tasks via ../high-risk-work-specialist/.

Method

1. Set the jurisdiction and regime — NZ (2016 Regs) or which Australian state? Surface or underground? Coal or metalliferous? This decides the law, regulator and statutory roles.
2. Confirm the statutory appointments & competencies (SSE / mine manager / ventilation officer; CoCs).
3. Identify the principal hazards for this operation and check each has a management plan.
4. Work the principal-hazard controls (ground, inrush, gas/ventilation, explosives, mobile plant, dust/health, tailings, emergency/self-escape).
5. Route the generic hazards to their SME (excavation, confined space, substances/dust method, mobile plant, machinery, electrical, height, water).
6. State residual obligations — the operator owes the duty under the mining regime; a documented management system, competent persons and emergency capability are mandatory. Hand off accordingly.

Jurisdiction note

NZ: HSWA 2015 + the HSW (Mining Operations and Quarrying Operations) Regulations 2016, regulated by WorkSafe NZ (extractives/high-hazards), with the Mining Board of Examiners for certificates of competence. AU: not harmonised — a state-based regime: Qld (Coal Mining Safety and Health Act 1999 / Mining and Quarrying Safety and Health Act 1999, RSHQ), NSW (WHS (Mines and Petroleum Sites) Act 2013 + Reg 2022, Resources Regulator), WA (WHS (Mines) Regs 2022, WHS Act 2020) and others. Always establish the state first. Detail and verify-pointers in references/regulatory-regimes.md; confirm current editions via ../hse-advisor/ / ../safework-au-specialist/.

Output

Either a mining/quarrying safety plan or risk screen (jurisdiction & regime → statutory roles & competency → principal hazards each with a control plan → routed generic hazards → emergency/self-escape → critical questions), or the extractives-specific controls and questions to feed into a bow tie (../critical-risk-manager/), task analysis (../task-analysis-author/) or SOP (../sop-author/). A draft for a competent person to validate.

Disclaimer

This skill produces good-practice extractives-safety guidance — not legal advice and not a substitute for a competent person or the current mining/quarrying safety law, which is a separate regime that differs between NZ and each Australian state. Mining principal hazards can cause multiple fatalities; geotechnical, ventilation, explosives, tailings and emergency-management controls require competent specialist engineering. Validate every appointment, control and management plan against the actual operation and the current regime before relying on it.
