摘要(Abstract)：

介绍了电解铝厂120m高钢筋混凝土烟囱及旧厂房定向倒塌爆破拆除的情况。针对烟囱高度大、环境复杂及旧厂房大跨度的特点,对爆破方案进行了精心设计;经过计算选取合理的爆破切口及定向窗的范围;采用延时控制爆破技术,同时对烟囱及旧厂房进行爆破拆除。通过安全校核,确保了附近厂房的安全。
A 120m-high reinforced concrete chimney and the old factory of a aluminum smelter factory were collapsed by directional blasting demolition.With the huge height and complex surroundings of chimney and the big span of the old plant,the blasting programme was carefully designed and the reasonable gap and scope of directional window were selected by calculation.Chimney and the old plant were demolished by millisecond control blasting technology.The security checking was adopted to ensure the safety of a nearby plant.
