摘要
文章介绍在周围环境较复杂的化工厂内爆破拆除一座外壁和内对均为薄壁、宽间隙隔热层这种特殊结构的钢筋混凝土烟囱的爆破技术设计，主要是根据烟囱本身的结构情况建立计算模型，进行爆破缺口参数的计算机辅助设计，药孔爆破和外部延长药包爆破相结合爆破烟囱内衬的方法，以及倒塌后的烟囱残体的二次破碎方法。
This article presents a design for blasting a thin chimney with a thin lining in it seperated by a wider heat - insulated layer in a chemistry plant. It is mainly to set up a calculating model, carry out a assistant design of paramenters of blasting breach by computer, combine the hole blast with the adolle shot in extended charges to blast the lining and use the mathod of the popping blasting of blast the fallen remainders of the chimney.
