| Abstract: | When a chimney of 150m is demolished by directional blasting in a long and narrow area with dimensions of 162 meters long and 44 meters wide, directional precision and moving-up must be controlled effectively. Design and implementation of directional blasting for demolition of a reinforced concrete chimney with a height of 150 meters in Huangshi Power Plant were introduced in this paper. According to the blasting effect, the reasons of deviation and moving-up were analyzed, and at the same time, the corresponding improvement was given. The experience obtained from the project can be used as a reference for similar projects. |
