本文介绍武钢冷轧厂的处于特殊位置的通风机室爆破拆除工程。经过对各种爆破参数进行精确计算,合理选择试爆方式和振动测试手段后,采用塑料导爆管非电起爆系统分段折叠倾倒方案并获成功。 This article describes the blasting and demolition of a ventilator chamber in a special location of the Wuhan Iron and Steel Cold Rolling Plant. After accurate calculation of various blasting parameters and reasonable selection of test explosion methods and vibration testing methods, the non-electrical initiation system of plastic igniter tube was adopted to achieve the segmented collapse dumping scheme.
