摘要(Abstract)：

介绍了采用定向控制爆破技术拆除复杂环境下45m砖烟囱的工程实例,通过采用提高爆破切口高度创造爆破条件,选用小角度定向窗保证倾倒的准确性,并选择合理的爆破参数、爆前预处理及防护措施确保了爆破拆除的圆满成功,可为此类爆破拆除工程提供参考。
The blasting demolition of 45 mbrick chimney under complex environment using directional controlling blasting technology was introduced.Increasing the cut height to create blasting condition and selecting the directional window with small angle to guarantee the accuracy of collapse.The reasonable demolition parameters,pretreatment and protective measures were taken to ensure the success.It could provide a reference for similar demolition projects.
