Abstract
The paper introduces a practical example of blasting demolition of dock cofferdam in special environment condition.Blasting parameters were selected reasonably in design,and the blasting vibration was decreased by applying the technique measures such as the hole-hole millisecond delay blasting technique,vibration-isolated hole,and effective safety protection measures were taken to protect objects.The blasting result shows that the blasting design and various safety measures are reasonable and feasible.
