| Abstract: | The problems of touchdown impact vibration and directional precision must be solved when a chimney with a height of 120 meters in a long and narrow area is demolished by directional blasting.In the light of blasting demolition of a reinforced concrete chimney with a height of 120 meters in the Emei Aluminum Factory,the tackle of several important problems such as soot door,recoil and eccentricity is introduced and the method and technological measures for control of directional precision are proposed.In addition,the calculation of blasting cut's parameters,check of safe vibration distance and the experience of authors are presented. |
