摘　　要：介绍的3栋砖混结构楼房,其特点是带内走廊,高宽比小,构造柱多。微差起爆网路分区由倒向至反向分3个区,区段分界线避开内走廊,纵向分区与横向分区相结合,以较小的爆破缺口高度,较少的炮孔,使楼房可靠定向爆破倾倒。This paper introduces a three-storey brick-concrete building with inside corridor, little height-to-span ratio and many posts. The delay interval firing circuit was designed into three districts from collapsing direction to its opposite direction, the line of demarcation avoids contacting inside corridor, and vertical districts are combined with horizontal districts to ensure building directional collapsed byside lower blasting cut and less blasthole.
