Study on Crush Progress of Rock in Delay Blasting
With the development of blasting technology and improvement of safety requirement,hole by hole initiation technique is commonly used in rock blasting engineering for lowering blasting vibration.And as the formation of new free surface resulted from the former hole initiated,thus its blasting effect is better than holes initiated simultaneously.But hole by hole initiation may cause high boulder yield,much bedrock,and so on in rock blasting engineering.For the solution of above problems,this paper study on explosion shock wave and explosion product taking action on rock,proposes scientific blasting design idea and basis for effective and safe blasting design blasting scheme by combination of theory,numerical simulation and practice.
