Fracture Controlled Blasting of Different Coupling Mediums in Bore Hole

  • Received Date: 13 Jun 2007
  • Publish Date: 25 Jun 2008
  • Based on the different physical and energy transfer characteristics of water and air,coupling blasting of different mediums (water and air) in the same bore hole was presented to control the release process and action direction of energy to control the generation and development of cracks.The effect of water and air coupling blasting on surrounding medium was analyzed,and strain and damage induced by coupling blasting of water and air were investigated experimentally.The research results show that water coupling blasting can generate great strain and damage than air coupling blasting,as a result,it is possible to destroy one side of surrounding rock and protect the other side.
