摘　　要：为了实现大型连体筒仓的定向拆除爆破,根据筒仓结构特点及周边环境情况,对筒仓顶部输煤栈桥和筒仓内部结构及切口范围进行了预拆除,在切口范围内的圈梁上部开凿了竖向切缝,并设计了合理的爆破切口范围和参数,采取了有效的安全防护措施。爆破效果表明,筒仓倒塌方向精准,爆破飞石和振动未对周边保护物造成破坏,确保了爆破期间电厂机组的正常运行发电,达到了预期效果,可为类似工程提供参考。In order to realize the directional blasting demolition of the large diameter joint silos,according to the structural characteristics of the silos and the surrounding environment,the coal handling trestle at the top of the silos,the internal structure and the cut range of the silos were predemolished,the vertical slits were cut on the upper part of the ring beam within the cut range,the reasonable blasting cut range and parameters were designed,and effective safety protection measures were taken.The blasting effect shows that the collapse direction of the silos are accurate,and the blasting flying rocks and vibration do not damage the surrounding protective objects,which ensures the normal operation of the power plant units during the blasting,and achieves the expected effect,which can provide reference for similar projects.
