摘　　要：爆破拆除的这座烟囱高度 30m ,砖砌结构 ,筒体厚 37cm ,在距地面 5m处爆破拆除 ,烟囱倒向的反侧紧连平房等建筑物 ,且需要保护。本文叙述了烟囱控爆方案和爆破参数设计 。A brick structural chimney with 30m heigh and 37cm wall thickness was demolished by controlled blasting with a cut at 5m from the ground. The opposite of collapsing direction of the chimney was a single storey house and other buildings which must be protected. The scheme and parameters of the controlled blasting were presented and the influence of the cut tosupporter relation on blasting recoil was briefly discussed in this paper.
