Elements and Performance Criteria

1. Plan and prepare for underground shaft installation
   • Access, interpret and apply underground shaft installation documentation and ensure the work activity is compliant
   • Inspect and evaluate site and ground conditions at the planned shaft location and determine the type of shaft to be sunk
   • Identify and address potential risks and hazards
   • Obtain and interpret emergency procedures, and be prepared for fire/accident/emergency
2. Excavate shaft
   • Conduct or facilitate shaft excavation in planned location
   • Stabilise unconsolidated ground to prevent falls of ground and shaft collar erosion
   • Ensure shaft is supported by shaft pillar to ensure the integrity of the bottom section of the shaft
   • Secure area over shaft collar to prevent surface water inflow
   • Ensure that brow area near the bottom of the shaft, and the geology and walls, are visible for inspection
3. Fit out shaft
   • Fit access ladders securely in shaft in accordance with shaft conditions and code of practice
   • Install hoisting equipment at the surface of the shaft
   • Ensure that services supply devices to the shaft wall are fixed away from shaft conveyance equipment
   • Install shaft protection to prevent falls by people and animals, and unauthorised entry into the mine
   • Ensure that access shaft is free of unnecessary equipment and fixtures to allow unrestricted movement of materials
