High Speed Imaging Camera

The face camera can quantify the following information:

• Initial face movement
• Differential face velocity
• Face trajectory
• Range of material cast
• Performance of various explosive types
• Benefit of different primer/booster combinations
• Effects of the delay timing configuration
• Performance of various blast designs
• Gas venting occurrence

The bench camera provides the blast designer with the following information:

• Ground swell velocity
• Actual firing time of delay elements
• Stemming confinement efficiency
• Effects of blast geometry
• Optimum delay interval between rows
• Cause of backbreak and origin of flyrock

Typical Frame Rates for capturing open pit blasts range from 500 – 1000 fps (our camera can record up to 10,000 fps!)

• Immediate availability of the blast for review (On the Camera)
• Confirmation of the firing sequence of holes
• Measurement of the firing time and scatter in detonators
• Assessment of the degree of confinement, stemming blowouts, and flyrock zones
• Confirmation of the functioning of explosives, primers, and accessories
• Determination of the location, time, and duration of gas venting
• Assessment of the locations responsible for flyrock or other projectiles
• Evaluation of the extent of backbreak
• Determination of the location, time, and duration of nitrogen oxide emissions
