| 摘 要： | 采用控制爆破拆除烟囱,是一种经济、安全而又简单可行的方法。南芬露天铁矿成功地进行了第1次烟囱控爆拆除,拆除的是一座旧方形烟囱。与圆形烟囱控爆拆除相比,易定向但不易倾倒,为此在设计计算时炸高应取偏大值,此经验值得借鉴。

| Abstract: | Chimn operate. Nanfen Iron ey demolition through controlled blasting is a method, which is economic, safe and easy to Mine carried out a controlled blasting in demolition of its chimney in the first time. The demolished chimney was an old square chimney. Its blasting demolition was easy to be conducted through directional blasting but hard to ensure an inclined collapse compared with the operation of the round one. For this reason, relative greater blasting height was determined in the design,offering a very meaningful experience for the similar project. |
