High Speed Video

Thomas Engineering Ltd. (TEC) can record and analyze blasts using state-of-the-art video equipment and software.

The information that may be obtained from the high speed digital video camera systems include:

  • the location of the first rock movement and the shape of the face movement
  • the firing sequence of the blast
  • the occurrence of gas venting at the face
  • the degree of confinement due to stemming
  • the occurrence and location of misfires
  • the nature of the muck-pile formation
  • the onset time for rock movement, both at the face and at the top of the bench
  • the velocity and direction of rock and flyrock travel from the face and the top of the bench
  • the hole venting and stemming ejection velocities
  • the actual hole/deck delay times
  • the casting range of the rock
