炼铁厂热风炉是一种特殊的高耸结构物,内部塞满高温耐火材料且炉体材料为多种介质,传统方法拆除难度很大。介绍了国内首次采用聚能爆破与钻孔装药爆破相结合的控制爆破技术拆除热风炉的成功经验。详细讨论了爆破切口的形状、切口高度、切口长度的选取原则和塌落振动控制。此外,还叙述了爆破参数、爆破器材、起爆网路和爆破效果等。 Iron furnace hot blast stove is a special high-rise structure, the interior is filled with high temperature refractory material and the furnace body is a variety of media, the traditional method of removal is very difficult. This paper introduces the successful experience of demolition of hot blast stove by using controlled blasting technology, which is the first time in China to adopt the combination of polyblend blasting and drilling charge blasting. Discussed in detail the shape of the blasting incision, incision height, incision length selection principle and slump vibration control. In addition, also describes the blasting parameters, blasting equipment, detonating network and blasting effects.
