摘　　要：介绍了电厂燃煤机组循环水取水口预留岩坎围堰的拆除爆破。针对围堰周边环境复杂的特点,从制定安全控制标准入手,进行爆破方案和爆破参数的设计,校核了爆破振动和水击波有害效应,并对过流危害采取了安全控制措施。爆破取得了预期效果,可为类似围堰拆除爆破工程提供参考。The demolition blasting of reserved rock ridge cofferdam for intake of circulating water of coal fired units in electric power plant was discussed. Aiming at complex surroundings of cofferdam to design blasting scheme and blasting parameters from standard of safety control, the blasting vibration and harmful effects caused by water hammer wave were checked, and safe measures to control harms of overflow were adopted. Expected blasting result was achieved and it could be a reference to similar projects.
