Abstract: “Drill and blast method is still most economical and efficient practice for different types of excavation. However, in vicinity of buried transmission pipelines, the vibrations must be held below recommended values. Influence of blast induced ground vibrations on buried pipelines has been described throughout three different projects. During the first project, oil pipeline has been partially open allowing extensive measurements directly on it.In this paper, only vibration monitoring data were analyzed and correlation equation between ground vibration and vibration on pipeline has been developed.Such equation is than used to predict vibration on the pipeline where direct measurements were not possible.”
