• Canada: Provincial mining regulations (Ontario Mining Act, BC Mines Act)
• South Africa: MHSA (Mine Health and Safety Act)
• International: ILO Convention 176, ICMM 10 Principles
• Industry standards: JORC, CIM, SAMREC (safety elements within resource reporting)

Step 1.3 -- Site and Operation Context

Map the mining operation:

Mining methods: open pit, underground (longwall, room-and-pillar, cut-and-fill, block caving, sub-level stoping), alluvial, in-situ leach, dredging

Step 1.4 -- Safety Performance Baseline

Establish current safety metrics:

• Total Recordable Injury Frequency Rate (TRIFR)
• Lost Time Injury Frequency Rate (LTIFR)
• Severity Rate (days lost per million hours worked)
• Fatal and high-potential incident count
• Near-miss and hazard reporting rate
• Leading indicators: inspections, observations, training hours, corrective action closure

============================================================ PHASE 2: INCIDENT INVESTIGATION ANALYSIS

Evaluate incident investigation quality and findings:

Step 2.1 -- Incident Classification and Trending

Analyze incident data:

• Incident classification: fatality, serious injury, medical treatment, first aid, near-miss
• Incident type distribution: struck-by, caught-between, fall of ground, mobile equipment, electrical, fire/explosion, inrush, respiratory, noise
• Body part injury distribution (hands, eyes, back, feet -- reveals exposure patterns)
• Incident rate trending: 12-month rolling TRIFR and LTIFR
• Shift and time-of-day patterns
• Experience-of-injured correlation (new starters vs. experienced workers)

Step 2.2 -- Investigation Quality Assessment

Evaluate investigation methodology:

• Investigation triggers: what severity level requires formal investigation?
• Methodology: ICAM (Incident Cause Analysis Method), TapRooT, 5-Why, BowTie
• Root cause depth: do investigations reach organizational factors or stop at individual behavior?
• Contributing factor analysis: latent conditions, absent or failed defenses
• Evidence collection: photos, statements, data downloads, preservation protocols
• Timeliness: investigation completion within required timeframe

Step 2.3 -- High Potential Incident (HPI) Focus

Assess HPI management:

• HPI identification criteria and consistency

• Potential consequence assessment methodology
• HPI trending and pattern recognition
• Critical control verification following HPIs
• Senior leadership engagement in HPI review

Step 2.4 -- Corrective Action Effectiveness

Evaluate whether investigations drive real improvement:

• Corrective action hierarchy of controls compliance:
  1. Elimination (remove the hazard)
  2. Substitution (replace with less hazardous)
  3. Engineering controls (isolate from hazard)
  4. Administrative controls (procedures, training, signage)
  5. PPE (last resort)
• Are most corrective actions engineering controls or just "retrain"?
• Corrective action closure rate and timeliness
• Effectiveness verification methodology and results
• Repeat incident analysis: same causes reappearing = ineffective corrections

============================================================ PHASE 3: HAZARD IDENTIFICATION AND RISK ASSESSMENT

Evaluate the hazard management framework:

Step 3.1 -- Hazard Register Completeness

Assess hazard identification coverage:

  • Ground/strata failure (open pit wall stability, underground roof/rib)
  • Inrush/inundation (water, mud, gas)
  • Fire and explosion (including spontaneous combustion)
  • Vehicle interaction (light vehicle vs. heavy vehicle)
  • Falling from height
  • Electrical hazards
  • Hazardous materials and atmospheric contaminants
  • Noise and vibration
  • Thermal stress (heat, cold)
  • Entanglement with moving machinery

Step 3.2 -- Critical Control Management

Evaluate critical risk controls per ICMM framework:

• Material Unwanted Events (MUEs) identified and ranked
• Critical controls defined for each MUE
• Critical control standards documented (what "good" looks like)
• Critical control verification: frequency, method, and accountability
• Critical control performance reporting to leadership
• Critical control failure response procedures

Step 3.3 -- Change Management

Assess safety implications of operational changes:

• Management of Change (MOC) process for equipment, process, and personnel changes
• Risk reassessment triggered by changes to scope, method, or conditions
• Pre-task risk assessment practices (Take 5, JHA, SLAM)
• Seasonal risk adjustments (wet season, heat stress, reduced visibility)
• Contractor change management (new contractor mobilization safety)

Step 3.4 -- Bowtie Risk Analysis

Evaluate or construct bowtie models for top risks:

• Threat identification for each MUE (what can initiate the event)
• Preventive controls (barriers between threat and event)
• Consequence identification (what happens if the event occurs)
• Mitigating controls (barriers between event and consequence)
• Escalation factors that can degrade controls
• Escalation factor controls

============================================================ PHASE 4: OCCUPATIONAL HEALTH AND EXPOSURE MONITORING

Evaluate occupational health programs:

• Refuge chamber provisioning and maintenance
• Inertisation capability for fire/explosion scenarios

============================================================ SELF-HEALING VALIDATION (max 2 iterations)

After producing output, validate data quality and completeness:

1. Verify all output sections have substantive content (not just headers).
2. Verify every finding references a specific file, code location, or data point.
3. Verify recommendations are actionable and evidence-based.
4. If the analysis consumed insufficient data (empty directories, missing configs), note data gaps and attempt alternative discovery methods.

IF VALIDATION FAILS:

• Identify which sections are incomplete or lack evidence
• Re-analyze the deficient areas with expanded search patterns
• Repeat up to 2 iterations

IF STILL INCOMPLETE after 2 iterations:

• Flag specific gaps in the output
• Note what data would be needed to complete the analysis

Summary Table

NEXT STEPS:

• "Run /mining-maintenance to assess equipment-related safety risks from condition monitoring data."
• "Run /extraction-optimization to evaluate if production pressure creates safety trade-offs."
• "Run /resource-estimation to align mine life planning with long-term safety infrastructure needs."

DO NOT:

• Do NOT recommend reducing safety controls or monitoring without engineering risk assessment.
• Do NOT normalize incident rates without accounting for exposure hours and workforce composition.
• Do NOT treat "retrain the worker" as an acceptable sole corrective action for significant incidents.
• Do NOT assess ground control risk without considering the intersection of geology, water, and operational sequencing.
• Do NOT downplay near-miss frequency -- high near-miss rates indicate future serious injury potential.

============================================================ SELF-EVOLUTION TELEMETRY

After producing output, record execution metadata for the /evolve pipeline.

Check if a project memory directory exists:

• Look for the project path in ~/.claude/projects/
• If found, append to skill-telemetry.md in that memory directory

Entry format:

### /mining-safety — {{YYYY-MM-DD}}
- Outcome: {{SUCCESS | PARTIAL | FAILED}}
- Self-healed: {{yes — what was healed | no}}
- Iterations used: {{N}} / {{N max}}
- Bottleneck: {{phase that struggled or "none"}}
- Suggestion: {{one-line improvement idea for /evolve, or "none"}}

Only log if the memory directory exists. Skip silently if not found. Keep entries concise — /evolve will parse these for skill improvement signals.
