| Abstract: | In this paper, a practical example on demolition of a reinforced concrete chimney with height of one hundred meters by directional blasting was introduced, the design of blasting scheme, the determination of blasting parameters, shape and size of blasting cut, the openning of directional window, priming circuit, safety precautions, lining treatment and others were discussed, the details of construction technology were especially described. An ideal blasting result had been achieved. Through the analysis of the blasting result, some valuable enlightenment and practical experience had been gained. |
