Safety Measures – Noise and Ground Vibrations

  • By carefully designing a blast hole drilling  pattern or blast geometry with appropriate burden distance, spacing as holes,  hole size, hole depth, and  stemming height, and powder factor.
  • Adopting shock tube (non-electrical) initiation system  in blasting  which allows  short  delay blasting using  short  delay detonators allowing in-hole  as well as surface  delay  and bottom  initiation of blasted rock and results  in reduction of fly rock, reductions in noise and ground vibration levels to within permissible limits.
  • A blasting siren and warning notice boards is being used to warn public and workers as safety measures.
