摘要
某水泥厂多座相邻的储罐和75 m高的砖混烟囱需一次性爆倒,因其相互距离很近,存在着倒塌场地受限、爆堆过高的问题,从而影响破碎效果。合理的延时和可靠的起爆网路是保证爆破能否正确按设计要求倒塌的重要因素。最后通过精心设计和施工,取得了良好的爆破效果,为类似爆破工程提供经验。
Storage tanks and 75 m chimney of a cement plant needed to be blasted simultaneously, but the distance between each other is small, so there are the limit collapsing field and too high blasting stack ,which influences the fragmentation effect. Reasonable delay and reliable initiation network are important factors ensuring collapse successfully. At last through the exact design and construction, the good blast effect was got and offered experiences to similar blasting projects.
