Abstract
The application of the technique of the excavation by long-hole type blasting in the Olympic Games flying-saucer stadium was introduced in the article. In the complicated surroundings,some techniques were adopted such as out-hole millisecond delay blasting, underload, the longer length of stemming to control the danger of blasting vibration and fly rock,at the same time,in view of the complex geological condition, presplitting blasting was adopted so that blasting parameters were optimized to make the side slope integrated.The paper summarized and provided some experiences of construction.
