Blast Preperation Audit


The foundation of the audit schedule is based on controlling and managing the resulting effects from blasting operations i.e. ground vibration, air blast, fly rock, fumes, fragmentation, explosive energy misuse, explosive quality deficiencies, improper blast controls, explosive stock control, improper blast results, safe and effective blasting procedures etc.

Following areas are controllable and influence outcome of results:

  • Blast Design
  • Burden & Spacing
  • Stemming length
  • Stemming material
  • Column Lengths
  • Initiation Pattern
  • Blast modelling
  • Charge mass per blast hole
  • Direction of initiation
  • Drill accuracy
  • Charging of blast holes
