| Abstract: | This paper introduced the implementation of demolition technical measures of directional blasting regarding a demolition of two 120m height reinforced concrete chimneys.The introduction emphasized the localization of the blasting cut,the choice of blasting parameter,the protective measures of blasting security and so on.It also made a careful design and scientific discussion on the issues such as the directional accuracy which was the most hard to control regarding the site environment,collapse length and touch ground protection.And moreover,the paper checked the blasting and collapsing vibration. |
