Core Responsibilities

Primary Functions

Lead and supervise an underground production crew (typically 8–20 personnel) on assigned shifts, assigning tasks, tracking progress against daily and weekly production plans, and adjusting work priorities to meet tonnage and grade targets while maintaining strict safety standards.
Enforce MSHA and company safety policies by conducting pre-shift tailgate talks, daily safety inspections, hazard assessments, and ensuring compliance with personal protective equipment (PPE) and work procedures.
Plan, coordinate and supervise ground control activities including roof bolting, mesh/shotcrete installation, scaling, cribbing and other ground support measures to manage ground stability and reduce exposure to ground fall hazards.
Direct drill-and-blast preparations and post-blast procedures: ensure timely hole charging, pattern accuracy, stemming, ventilation clearance, and effective mucking following blasting operations while adhering to explosive handling rules and shotfirer directives.
Schedule and coordinate equipment and personnel for production cycles (drilling, blasting, mucking, scaling, bolting), manage shift turnovers, and communicate production handoffs to incoming supervisors to maintain continuity of operations.
Operate and/or oversee operation of underground mobile equipment (LHD, scoops, chargers, underground trucks, jumbos), ensuring operators are trained, licensed where required, and that equipment is used according to safe operating procedures.
Perform and document routine underground inspections (roof conditions, rib, floor, ventilation, water inflows), raise work orders for maintenance, and coordinate with maintenance crews to expedite repairs that impact production or safety.
Conduct incident investigations for near misses, lost-time incidents and property damage: lead root-cause analysis, produce corrective action plans, and follow up to ensure timely implementation and closure.
Develop and maintain daily production and safety reports, input data into mine planning and reporting systems, and liaise with operations planning/geology to confirm face targets and sequence.
Mentor, train and appraise crew members: deliver on-the-job training in mining techniques, safe work procedures, emergency response, and skills cross-training to build bench strength and reduce turnover.
Manage workforce administration on shift: verify timecards, approve leave requests, enforce attendance standards, and participate in performance management and disciplinary actions as required.
Implement and continuously improve standard operating procedures (SOPs) for underground tasks, incorporate feedback from crews, and align procedures with company policies and regulatory requirements.
Oversee ventilation control on shift: ensure face and return air quantities are maintained per plan, manage stoppings and regulators, and coordinate temporary ventilation changes during blasting or servicing.
Control hazardous energy for equipment maintenance (lockout/tagout) underground, verify isolation before maintenance, and ensure maintenance work permits comply with safety standards.
Monitor and manage consumables and inventory levels for bolting, blasting, roof support, and ground control materials; place orders or escalate shortages to logistics to prevent production delays.
Coordinate emergency response and mine rescue readiness: maintain and test communications and refuge stations, lead emergency drills, and ensure crew proficiency in evacuation and first aid procedures.
Drive productivity improvements by analyzing shift performance, identifying bottlenecks, implementing process fixes (material flow, cycle time reduction, staging), and tracking KPIs such as tons per man-hour and equipment availability.
Engage with cross-functional teams (geology, planning, environmental, maintenance) to implement short-term fixes and long-term plans that improve face selection, dilution control and ore recovery.
Ensure environmental controls underground (water management, dust suppression, waste handling) are applied consistently and report environmental incidents immediately per company procedures.
Supervise contractors working underground: verify competency, ensure contractors adhere to site-specific safety and quality requirements, and manage contractor access and permits.
Enforce quality control on face development and ore handling: verify rock breakage, dilution limits, and proper bin sequencing to protect product quality and minimize rework.
Maintain and review training records, certifications and competency matrices for the crew; coordinate required regulatory training (MSHA Part 46/48, first aid) to keep crew credentials current.
Support shift budgeting and cost controls by tracking labor hours, materials usage and minor equipment costs; recommend cost-saving initiatives without compromising safety or production.
Serve as a visible safety leader underground: lead by example, participate in safety committees, escalate systemic hazards and promote a positive safety culture.

Secondary Functions

Prepare and submit shift handover reports and production logbooks for the incoming shift supervisor.
Support short-term mine planning by providing real-time face feedback to planners and geologists to refine development sequences.
Participate in hiring and onboarding of underground personnel, including competency checks and buddy tagging for new hires.
Assist in the development and delivery of training modules for roof bolting, ground control, and mobile equipment operation.
Collaborate on continuous improvement projects such as improved mucking patterns, ventilation optimization and material staging to increase throughput.
Contribute to community and regulatory engagement as needed (site tours, inspections, audits), presenting accurate operational and safety information.
