a designated underground haulage route.","Electrical cable hazards — recognize and report using basic safety awareness protocols in an active mine entry.","Rubber safety gloves — select and don correctly before moving trailing electrical cables clear of obstructions on a mine floor.","Hand signals and grade stakes — observe and interpret with crew assistance when positioning loading equipment at the working face.","Roadway obstructions — identify and flag for removal before driving a machine through an underground travel way.","Conveyor belt controls — engage and monitor under supervision to distribute material loads during routine shuttle car loading cycles.","Crowbar techniques — assist in prying loose roof material into machine paths under the direct instruction of an experienced operator.","Pre-shift equipment checks — complete using a provided checklist before operating a loading or moving machine at an underground mining site.","High-voltage cable locations — recognize and avoid contact with, following posted safety procedures in a mine entry.","Basic machine controls — practice coordinating hand and foot inputs to maneuver a shuttle car on a level underground roadway under close oversight."]},"developing":{"label":"Developing","statements":["Loaded shuttle cars — drive independently to mine ramps and operate discharge controls to unload material into mine cars or onto conveyors with minimal supervision.","Trailing electrical cables — move clear of equipment travel paths using rubber safety gloves, applying standard cable-handling procedures in active mine sections.","Conveyor length distribution — control conveyor speed and direction along the full length of a shuttle car to balance loads evenly as material accumulates during routine operations.","Blasted material faces — drive loading machines into piles with consistent control precision, adjusting approach angle to optimize scoop capacity in familiar underground conditions.","Roof scaling operations — use a crowbar to pry and relocate loose roof material ahead of machine travel routes without direct instruction in established work areas.","Hand signals and grade markings — interpret and respond to accurately while multitasking machine operation in a moderately congested underground environment.","High-voltage sources — handle and re-hang electrical cables safely following mine electrical procedures, with awareness of live-circuit hazards in underground entries.","Equipment malfunctions — identify common mechanical faults through operational monitoring and report findings clearly to maintenance personnel during a shift.","Underground roadway conditions — examine and clear obstructions from travel paths independently before and during machine operation to maintain safe haulage flow.","Shift production logs — record machine operating hours and load counts using time accounting or inventory software at the end of each underground shift."]},"proficient":{"label":"Proficient","statements":["Full-cycle shuttle car operations — perform autonomously across loading, haulage, and discharge phases, adapting to changing roadway and face conditions throughout an underground mining shift.","Non-routine electrical cable situations — troubleshoot and safely re-route high-voltage cables around equipment or roof falls without supervisor intervention in active mine sections.","Complex load distribution — regulate conveyor speed and timing across varying material densities and volumes to prevent overloading while maximizing throughput on a continuous basis.","Difficult terrain navigation — maneuver loading machines through tight entries, grades, and turns with precise multilimb coordination, minimizing equipment contact with rib and roof.","Roof hazard assessment — independently scale and clear loose material from machine travel zones, making real-time judgments about safe entry into blasted areas.","Equipment malfunctions — diagnose and perform field-level troubleshooting on shuttle cars and conveyors, applying mechanical knowledge to restore operations and limit downtime.","Crew communication — convey operational status, hazard observations, and equipment issues clearly and concisely to shift supervisors and co-workers in high-noise underground environments.","Safety compliance monitoring — observe and correct unsafe cable-handling or machine-operating practices by co-workers using site safety standards and personal authority as a senior operator.","Preventive maintenance tasks — carry out scheduled lubrication, inspection, and minor repairs on loading and moving machines in accordance with manufacturer and mine maintenance schedules.","Operational data entry — accurately log production metrics, machine hours, and incident observations in industrial control or time accounting software to support shift reporting requirements."]},"advanced":{"label":"Advanced","statements":["Underground machine operations program — lead the development and continuous improvement of operating procedures for loading and moving equipment across an entire mine section or operation.","Operator training and mentorship — design and deliver structured on-the-job training for new and developing operators, building their machine control, cable-handling, and safety competencies.","High-voltage electrical safety standards — establish and enforce site-specific procedures for cable handling and electrical hazard management, ensuring compliance across all operating crews.","Production efficiency strategy — analyze haulage cycle times, conveyor distribution patterns, and loading face layouts to recommend operational changes that increase throughput and reduce equipment wear.","Equipment maintenance culture — champion a preventive maintenance program across the department, coordinating with mechanics and operators to reduce unplanned machine downtime in underground sections.","Cross-functional hazard communication — collaborate with mine engineering, safety, and supervision teams to identify, evaluate, and communicate roadway and roof hazard risks before they affect operations.","Incident investigation leadership — lead root-cause analyses of equipment-related incidents or near-misses, developing corrective action plans and presenting findings to mine management.","Workforce scheduling and coordination — plan and allocate operator assignments across shifts and work zones, balancing skill levels and production demands to sustain safe haulage operations.","Technology adoption — evaluate and guide the implementation of industrial control software and monitoring tools for shuttle car and conveyor operations, supporting crew adoption and compliance.","Organizational safety culture — model and reinforce dependability, integrity, and cautiousness at the leadership level, setting the behavioral standard for all underground machine operators across the site."]}}},"sources":{"onet":"v30.2 (CC BY 4.0)","crosswalk":"https://skillscrosswalk.com","generator":"LER.me"},"attribution":"©
