摘要
介绍了60 m高砖烟囱定向倒塌爆破拆除的情况。针对壁厚较大及倒塌后方有煤气管道等高危物品,对爆破方案进行了精心设计,开设了定向口,进行了爆破安全校核,采取了有效的安全防护措施。最后对爆破结果进行了分析,取得了一些成功的经验,对今后类似的爆破工程提供有益的借鉴。
The directional collapsing blasting for a brick chinmey with height of 60 m is introduced. In accordancc with relatively large wail thickness and high dangerous property such as coal gas line, the callapsing zone and the design of blasting program are determined, and safety precautions are provided. The blasting effect is analysed,some successful experiences have been obtained, which can be used as benefie references for similar blasting engineering.
