Ground Control Audit Template (ISO 45001 Aligned)
The Ground Control Audit Template (ISO 45001 Aligned) is a structured, evidence-based assessment tool designed to evaluate the effectiveness of ground control and rock mechanics management systems within mining operations against the requirements of ISO 45001:2018 for occupational health and safety management. It integrates geotechnical risk management with systemic OH&S governance—ensuring hazards related to ground instability, rockfalls, and structural failure are proactively identified, evaluated, and controlled. The template supports continual improvement through audit findings, corrective actions, and leadership review aligned with Plan-Do-Check-Act (PDCA) methodology.
📖 Overview
📑 Key Components
🎯 Applications
- ✓ Internal OHSMS compliance audits for mining sites
- ✓ Contractor ground control capability assessments prior to mobilization
- ✓ Regulatory readiness reviews (e.g., MSHA, DMRE, or equivalent jurisdictional bodies)
📐 Key Formulas
Risk Priority Number (RPN)
RPN = Likelihood × Severity × Detectability
A semi-quantitative scoring method used in ground control risk registers to prioritize hazards (e.g., high-wall failure in pit slope); adapted for ISO 45001 context by anchoring Likelihood and Severity to OH&S outcomes.
Factor of Safety (FoS)
FoS = Resisting Forces / Driving Forces
Fundamental geotechnical metric assessing stability margin of engineered supports or natural slopes; audited for design basis documentation, field verification, and recalibration after seismic or hydrological events.
