Job Responsibilities and Duties:

The Supervisor - Mine provides frontline leadership for the safe, efficient, and compliant execution of daily underground mining operations.

The Supervisors primary duties are:

• Reinforce Group Minimum Standards, critical controls, lifesaving behaviors, standard operating procedures, and approved work methods; stop unsafe work immediately, establish effective controls with the crew, document required follow-up, and elevate recurring or high-consequence deficiencies to the Execution General Foreman.
• Maintain visible field presence each shift by observing pre-shift preparation and work in progress, speaking with crews, reviewing workplace examinations and equipment inspections, verifying safe conditions, and documenting coaching or corrective action for General Foreman follow-up when required.
• Report incidents and near misses immediately by securing the area, caring for affected employees within training and authority, notifying the Execution General Foreman and required responders, recording known facts in approved systems, preserving evidence, supporting the investigation, and completing assigned corrective actions, retraining, and documentation within established timeframes.

• Provide real-time coaching, recognition, and corrective feedback; document significant discussions and recommend hiring, development, recognition, performance, or succession actions to the General Foreman.
• Apply attendance, conduct, performance, labor-relations, and Collective Bargaining Agreement requirements consistently by gathering and verifying facts, discussing expectations directly with the employee, documenting the interaction and business basis for action, initiating established processes within delegated authority, and consulting or escalating to the General Foreman and Human Resources when appropriate.
• Direct shift execution and maintain plan compliance by comparing actual progress with the shift plan, inspecting active and completed work, correcting quality or productivity issues, and coordinating timely assistance from the General Foreman and affected support functions.
• Identify constraints, changed conditions, missed work, and break-in work; resolve matters within delegated authority and the shift horizon, or promptly provide the Execution General Foreman with the operational impact, available options, resource needs, and recommended priority before commitments are affected.
• Coordinate work with other Supervisors and affected functions by reviewing shared work areas, interfaces, access, equipment, services, and timing before execution; document owners and required completion times, verify commitments during the shift, and elevate unresolved dependencies before they cause downtime, delay, or plan variance.
• Maintain environmental compliance within the assigned area by integrating applicable procedures, permits, controls, and inspection findings into shift execution and completing assigned corrective actions on schedule.
• Control shift labor, overtime, contractor use, equipment allocation, materials, tools, and consumables against the approved plan by monitoring actual use, stopping misuse or avoidable expense, and authorizing exceptions only within delegated authority.
• Validate safety, production, development, quality, workforce, equipment, cost, work-order, and environmental information against source records; correct omissions or inaccuracies before submitting reports through approved.
• Perform other duties as assigned.
