摘要(Abstract)：

在150m高钢筋混凝土烟囱的定向爆破拆除中,选择合理的切口形状和参数,对定向窗口进行精确施工、覆盖和挂网,开挖减振沟,地面软化处理等措施最终安全实施并达到了预计爆破效果。重点介绍了爆破切口的形状和尺寸、预处理措施、爆破参数、起爆网络、爆破切口的近体防护和倒地塌落振动防护措施,可为类似工程提供参考。
The 150 mhigh reinforced concrete chimney was demolished by directional blasting.Reasonable cut shape and parameters were chosen,and accurate construction of directional window,covering,hanging,excavation ditch,the ground softening treatment of effective measures were taken.Blasting safety implementation and the expected results finally were achieved.The blasting cut shape and size,pretreatment measures,blasting parameters,initiating network,blasting cut near body protection and the ground collapse vibration protective measures were emphatically introduced.It could provide a reference for similar engineerings.
