| 摘 要： | 船坞围堰拆除爆破,通常采取水下炸礁与围堰分次爆破,以便可靠起爆、减少一次爆破炸药用量、降低爆破震动影响。本文介绍了将水下炸礁与围堰一次性用倾斜深孔爆破的工程实例,并采用一般的钻孔机械、普通爆破器材,安全成功地实施船坞围堰拆除爆破,对类似工程具有很好的参考价值。

| Abstract: | The blasting for demolition of boatyard cofferdam is often operated by dividing the operation into underwater rock blasting and stage cofferdam blasting so as to reduce the charge quantity in one blasting, to increase the blasting vibration and to ensure a reliable ignition. The paper discussed one engineering blasting example of underwater rock and cofferdam blasting by using common drill device and common blasting material. The experience from this paper could be of value to similar engineering. |
