Key Responsibilities and Required Skills for Underground Safety Supervisor

🎯 Role Definition

The Underground Safety Supervisor is a front-line safety leader responsible for planning, implementing and continuously improving mine-specific health and safety programs in underground operations. This role directs daily safety activities, enforces regulatory compliance (MSHA/OSHA and local requirements), conducts risk assessments, leads incident investigations, and coordinates emergency response and rescue teams. The supervisor partners with operations, maintenance and contractors to drive a zero-harm culture, ensure safe mine design elements (ventilation, ground control, energy isolation), and deliver practical training and coaching to crews at the face, shaft and development levels.

Core Responsibilities

Primary Functions

Develop, implement and maintain the site Underground Safety Management System (SMS) aligned with corporate HSE standards and MSHA/OSHA regulations, ensuring documentation, version control and accessibility for all stakeholders.
Lead daily pre-shift and shift-change safety briefings and toolbox talks for underground crews, ensuring clear communication of hazards, control measures, emergency procedures and planned work sequences.
Conduct detailed hazard identification and risk assessments (JSA/JHA/HAZID) for all underground activities — development, stoping, blasting, bolting, shaft work and mobile equipment operations — and ensure documented controls are applied.
Plan and oversee emergency response and underground rescue capability: maintain, test and train mine rescue teams, coordinate drills (surface and subterranean), and ensure rescue caches, breathing apparatus and communication systems are serviceable.
Perform systematic underground safety inspections and audits (daily, weekly and monthly) including face area checks, ventilation monitoring, ground control condition assessments, rib and back stability, and corrective action tracking.
Monitor and manage mine ventilation programs: validate airflow models, verify methane/CO monitoring systems, enforce gas-free work permits, and support ventilation improvement projects to control airborne contaminants.
Lead root-cause incident investigations for all safety events and near-misses using structured methodologies (e.g., 5 Whys, RCA), produce clear investigation reports, determine corrective actions and follow up to closure.
Manage permit-to-work and hot work systems underground: issue and audit permits, ensure energy isolation (Lockout/Tagout) for all maintenance, and enforce confined space entry protocols.
Oversee ground control programs: evaluate roof and rib control plans, approve support design for headings and stopes, coordinate testing of bolts/mesh and ensure contractors comply with ground control standards.
Enforce PPE standards and respiratory protection programs underground; supervise fit-testing, training, replacement programs and PPE audits.
Coordinate safety onboarding, role-based training and competency assessments for new hires, contractors and temporary staff, ensuring training records meet internal and regulatory audit requirements.
Manage contractor prequalification, induction and ongoing performance monitoring to ensure contracted crews operate to the same safety standards as site personnel.
Maintain safety performance data, KPIs and dashboards (incident frequency, TRIFR, near-miss rates, corrective action ageing) and deliver monthly performance reviews to site leadership with prescriptive improvement actions.
Advise on design and scheduling to ensure safe work sequencing for blasting, ground control, equipment deployment and shaft maintenance; contribute to pre-planning and pre-start risk reviews.
Enforce isolation and energy control procedures for mobile and fixed plant underground, and supervise mechanical/ electrical maintenance workspaces to eliminate crushing, entanglement and stored energy hazards.
Ensure compliance with explosives handling and storage regulations where applicable; supervise magazine security, blast plan approvals and post-blast testing and clearance procedures.
Participate in regulatory inspections and incident responses with MSHA/OSHA and other authorities, prepare required reports, and implement regulator feedback and action plans in a timely manner.
Implement behavioural-based safety (BBS) initiatives to influence safe work practices, conduct observation coaching, and drive employee engagement in safety improvement programs.
Manage safety budgets for PPE, monitoring equipment, training and emergency response maintenance; recommend investments in monitoring technologies (gas detectors, communication) that reduce risk exposure.
Support continuous improvement: lead safety improvement projects (catch-bond redesign, ventilation upgrades, procedural revisions), pilot new controls, and evaluate effectiveness through measurable outcomes.
Supervise and mentor safety staff and shift personnel, set performance objectives, conduct performance reviews and develop competency plans to grow internal safety capability.
Maintain comprehensive records — safety documentation, incident files, inspection checklists, training records and audit trails — to support internal reviews and regulatory compliance audits.
Collaborate with medical, HR and EHS teams to manage occupational health programs (hearing conservation, dust control, fitness-for-work and fatigue management) tailored for underground environments.
Provide technical advice on mobile equipment selection and controls for underground use, including proximity detection systems, speed controls and traffic management plan development.
Support change management for new mining methods, equipment or processes by conducting risk assessments, creating pre-start safety packs and monitoring initial implementation.

Secondary Functions

Support production planning with safety input during weekly pre-start meetings to ensure safe sequencing of development and stope activities.
Assist procurement with technical specifications for safety-critical equipment (ventilation fans, gas monitors, escape sets, lifesaving appliances).
Participate in cross-site safety committees, sharing lessons learned, standardizing procedures and adopting best practices across the business unit.
Provide input to incident insurance claims and legal inquiries by preparing factual safety timelines, records and corrective action evidence.
Mentor and coach frontline supervisors on effective safety leadership, observation techniques and how to run meaningful toolbox talks.
Support continuous monitoring programs by coordinating data collection from portable gas monitors, environmental sampling and vibration/noise surveys.
Contribute to safety-related training content development: e-learning modules, practical rescue scenarios and competency assessment frameworks.
