介绍了一座常见砖砌烟囱的爆破拆除。爆破方法的特点是药量不均匀分布。倒塌方向两侧的切口被划分成不同的范围 ,其中的炮孔装以不同的药量 ,对倒塌方向两侧1/5切口长度范围内的炮孔加强了装药量。文中还论述了药量不均匀分布的优点 ,并对开设定向窗的药量与爆破效果的关系、内衬的预处理等问题进行了讨论 Describes the demolition of a common brick chimney. The blasting method is characterized by an uneven distribution of doses. The incisions on both sides of the direction of collapse are divided into different ranges, one of which is filled with different doses, and the charge of which is increased within one-fifth of the length of the incision on both sides of the direction of collapse. The article also discusses the advantages of the uneven distribution of dose, and discusses the relationship between the dose of the oriented window and the blasting effect, the pretreatment of the lining and other issues
