摘要(Abstract)：

介绍一座砖混结构楼房控爆倒塌场地受限时,如何设计不同的炸高,采取孔内毫秒延时起爆网路以及有效的防护措施,使楼房划分的A、B、C三部分,按各自指定的方向倒塌。该工程解决了倒塌距受限问题的成功经验值得借鉴。
Taking the demolition of a building in brick-concrete structure by controlled blasting as an example,this paper presented the successful experience of overcoming the restriction of collapse space in demolition.The distance for the collapse of the building was controlled through stage blasting and millisecond ignition network inside the borehole and the adoption of effective protection measures.The demolition reached its ideal safety effect in the restricted area.
