摘要:
为了确保电厂生产区内高150 m和180 m两座钢筋混凝土烟囱在一次性爆破拆除中的安全倒塌，在周围环境复杂、设备正常运行的条件下，采用了高位切口控制爆破和延时起爆技术，交叉定向倾倒爆破拆除两座烟囱的爆破技术方案，切口位置分别位于距地面25.0 m和30.0 m处，两烟囱间起爆延期时间为5 s。实践表明，爆破参数、切口位置、倒塌方向和5 s延期时间的选择合理可行，爆破效果良好。
Abstract:
To ensure the safe collapse of two reinforced concrete chimneys of 150 m and 180 m high sitting in the production area of power plant in a single blasting demolition, the technology of directional blasting of high position blasting cut and delay detonator, and the blasting technical scheme of crossed directional blasting demolition of two chimneys were used in the condition of complex environment and the normal operation of equipment. The blasting cuts were located at 25.0 m and 30.0 m from the ground respectively for the chimneys of 150 m and 180 m. To the two chimneys, the initiation delay time was 5s. Practice shows that the choices of blasting parameters, cut location, collapse direction and 5s delay time are reasonable and feasible, resulting in good blasting effects.
