【摘要】 采用定向爆破技术成功拆除了一座72m高的砖结构厚壁烟囱。根据现场实际情况和烟囱的结构与尺寸,合理选择爆破方案,如爆破缺口的形状和尺寸、爆破参数及爆破网路,并采取了一系列科学合理的安全技术措施,使得爆破达到了预期的效果,本次设计与施工对于类似爆破工程具有一定的借鉴意义。更多还原

【Abstract】 Using directional blasting technique,a thick-wall brick chimney with 72 the height of meters was demolished.Based on the actual condition and the size and structure of the chimney and the blasting scheme was chosen reasonably,such as blasting cut shape and size,blasting parameters and the firing networks.Many scientific safety measures were adopted,which makes the blasting achieve the desired result. This blasting design and work will provide a certain reference to similar blasting engineering.更多还原
