Analysing the Ground Vibration Due to Blasting at

Feb 02, 2013 One of the most fundamental stages in open pit mining is drilling and blasting. A good fragmentation and a minimum ground vibration are characteristics of a successful drilling and blasting operation. In this study, 78 blasting events of AlvandQoly limestone mine located in Kurdestan cement company in west of Iran were investigated. The vibrations induced blasting was recorded by
