The Supervisor - Underground Backfill & Construction leads the safe, efficient, and compliant execution of underground backfill and mine-infrastructure construction. Reporting to the General Foreman, this position converts the weekly plan into resource-ready shift work. The position directs backfill placement, barricade and bulkhead work, concrete, shotcrete, piping, pumping, excavation, fabrication, and underground service installations. They coordinate with Operations, Maintenance, Technical Services, and contractors to support the overall execution of mine objectives. The Supervisor verifies work readiness and quality, manages variance within delegated authority, escalates constraints, and provides accurate field information to support safe sequencing, plan execution, cost control, and reliable infrastructure.

The Supervisors primary duties are:

• →Reinforce Group Minimum Standards, critical controls, lifesaving behaviors, ground-control requirements, energy-isolation procedures, confined-space and hot-work controls, fall protection, lifting and rigging standards, concrete and shotcrete procedures, and approved work methods and stopping unsafe work, establishing effective controls, documenting follow-up, and escalating recurring or high-consequence deficiencies.
• →Maintain visible field presence across active backfill headings, barricades, bulkheads, pour sites, batch or transfer points, pump and pipeline routes, construction projects, excavations, and fabrication areas while verifying workplace examinations, pre-operational inspections, ground conditions, ventilation, access, and housekeeping.
• →Verify controls for pressurized backfill and grout systems, line charging and flushing, stored energy, line-of-fire exposure, blocked or failed pipelines, barricade integrity, concrete placement, shotcrete rebound and exposure, welding and cutting, mobile-equipment interaction, suspended loads, and work near open holes or brows.
• →Confirm that construction and backfill work comply with approved designs, ground-support requirements, specifications, cure times, and release criteria before areas are entered, filled, commissioned, or returned to operations.
• →Control and report incidents, near misses, material releases, line failures, barricade or bulkhead deficiencies, unplanned ground movement, equipment contact, and quality nonconformance immediately, by securing the area, notifying responders, preserving evidence, supporting investigations, and completing corrective actions.
• →Continuously monitor the fit-for-duty status of crew members and intervene using approved tools and resources, including reasonable suspicion testing, removing individuals from unsafe situations, and notifying designated functions as required.

• →Direct backfill preparation and placement, including area readiness, cleanout, barricade or bulkhead installation and inspection, pipeline installation and pressure checks, material delivery, placement rate, fill level, flushing, sampling, cure or drainage requirements, and documented release of completed work.
• →Direct underground construction and rehabilitation including excavation and setup, forms and reinforcement, concrete and shotcrete, grout, pipe and pump systems, sumps and drainage, ventilation and utility installations, steel and wood fabrication, welding and cutting, platforms, doors, chutes, guards, and other mine infrastructure within the approved scope.
• →Coordinate continuously with Mine Operations, Maintenance, Technical Services, Supply Chain, and contractors regarding design requirements, work-front readiness, service interruptions, access, blasting windows, materials, equipment, inspections, commissioning, and turnover.
• →Maintain environmental compliance by controlling cementitious materials, contaminated water, spills, leaks, dust, fumes, waste, scrap, and housekeeping and by protecting drains, sumps, water systems, and designated disposal routes.
• →Perform other duties as assigned.

• Adaptability and stress tolerance to maintain sound judgment and professional communication during emergencies, disruptions, and competing demands.
• Knowledge of underground hard-rock backfill methods and construction practices, including paste, cemented, hydraulic, or rock fill as applicable; barricades and bulkheads; forms, reinforcement, concrete, shotcrete, grout, piping, pumping, drainage, excavation, fabrication, and mine-service installation.
• Knowledge of MSHA, environmental, contractor, qualification, inspection, incident-reporting, quality control, corrective action, recordkeeping, cost control, and continuous improvement applicable to mine support.

• High school diploma or equivalent.
• Five years of progressively responsible underground hard-rock mining experience, including substantial experience in backfill, underground construction, mine support, infrastructure installation, concrete or shotcrete, piping and pumping systems, or closely related work.
• Current certifications, licenses, or task qualifications required by law or site standards for the assigned backfill and construction scope, or the ability to obtain them within the timeframe established by the Company.
• Associate or bachelor's degree in mining, civil or construction engineering technology, construction management, operations management, occupational safety, or a related field preferred.
