摘要:
针对待拆除的65 m高烟囱的基本情况和复杂的周围环境，充分考虑场地宽度不够等实际情况，采用双切口分段折叠定向爆破的方法对烟囱进行拆除。在设计中，进行了双爆破切口位置的爆高计算和校核，选择了上、下两个切口的孔网参数、单耗和总药量等爆破参数，进行了爆破振动安全的验算，确定了有效的安全防护措施。实现了烟囱的安全、定向拆除，达到了预期的效果。
Abstract:
Because of the complicated surrounding and narrow space around the 65 m chimney to be blasted, unidirectional folding blasting demolition with double incision method was employed. In this design, positions of the two incisions were calculated and checked, and blasting parameters of the two incisions, such as charging holes, blasting circuit, single charge and total charge, were determined.Effective safety measures were decided according to the check of blasting vibration safety. The blasting demolition is safe and directional, and it achieves desired effect.
