Kimje, Aug 12, 2019 (Issuewire.com) – Sunghyun-ENG is a manufacturer specialized in manufacturing and distributing low-noise eco-friendly construction equipment.

DSB: Downtown Smooth Blasting:

  • DSB is ultra-low vibration blasting technology compare to conventional blasting technology, and the small blasting hole diameter of 41mm can be drilled utilizing SRD-5000.
  • The blasting holes diameter of 41~51mm drilled by SRD-5000 with ultra-low vibration and noise and the explosive diameter of 17~32mm can apply according to holes diameter.

Decoupling Index and Smooth Blasting:

Characteristics of Decoupling Index

Relationship between Tangential Stress and Decoupling Index

  • As decoupling index increases, tangential stress decreases on the hole wall.
  • Consistent tangential stress is maintained when decoupling ratio is 1:1.
  • The blasting velocity and pressure are slow and low in the air than in substance.
  • When the charging length is long, higher blasting velocity explosive can be used to prevent blasting failure due to channel effect.
  • Decoupling index of 1.5~2 is applied for smooth blasting.
  • Decoupling index increases as blasting rock are harder and sound while decreases as it is softer and fractured.
