Vibration

Blast and vibration monitoring at Cadia Valley Operations (CVO) is managed in accordance with the CVO Blast and Vibration Monitoring Program (CVO BVMP) which was approved by NSW Department of Planning in June 2014.
Monitoring undertaken includes:

  • Ground vibration monitoring
  • Airblast over pressure monitoring

Vibration monitoring is conducted using the following:

  • a geophone set to trigger during ground vibration events greater than 0.10mm/s
        - will record peak vector sum (PVS mm/s) waveforms; and
  • a sound level meter or microphone as part of the blast monitor unit and set to trigger on ground vibration events
        - will record air overpressure peak (dB(Linear)) waveforms

Newcrest Blasting Schedule at CVO

All CVO blasts are designed to comply with blasting and vibration impact criteria specified in the Cadia East Project Approval (PA-06_0295).
