中文摘要: 介绍了采用定向控制爆破技术在周围建筑物密集条件下拆除一座53 m高砖烟囱的工程实例。根据烟囱特点及周围环境，通过计算分析，选择合理的爆破方案，用定向窗保证倒塌的准确性，并选择准确的爆破参数、爆前预处理及防护措施，取得了良好的爆破效果，确保了爆破拆除的圆满成功，为类似环境爆破拆除工程提供参考。
Abstract:This paper introduces a project of a 53 m-high brick chimney demolished in the way of directional blasting in the complicated environment with many buildings nearby. According to the chimney characteristics and surrounding environment, the blasting scheme is chosen by careful analysis and calculation, including the blasting cut, collapse direction and blasting network. Selecting the directional windows to guarantee the accuracy of collapse and the reasonable demolition parameters, pretreatment and protective measures are taken to ensure the success. Finally, we get the perfect blasting effect, and it can provide reference for similar demolition projects.
