摘　　要：采用两段两次控制爆破拆除了150m高钢筋混凝土烟囱。通过选用复式梯形爆破缺口和合理的爆破参数,并采用开挖减振沟及铺设缓冲垫层等安全防护措施,使烟囱爆破达到了定向准确、安全、破碎好的效果,可为类似爆破工程提供参考。A 150-meter reinforced concrete chimney was successfully demolished by directional blasting.The blasting design used composite blasting gap,chose reasonable blasting parameters,and took reasonable security measures,which guaranteed to achieve better blasting results in terms of the accurate direction,safety,and good breakage of the fragments.The paper provides reference to the similar project.
