800吨级特殊硐室控制爆破

本工程以爆后岩石超400kg的大块占爆破方量的30%以上,以利于填海筑堤为目的,采用硐室控制爆破、布置单层药包、最大药包分成两个药包、导爆管非电秒延期控制起爆技术,获得了良好的爆破效果。

800T SPECIAL COYOTE CONTROLLED BLASTING

In this project, over 400kg weight lump rock occupied 30% of the total blasted rock volume. For purpose of sea filling and dyke building, the chamber controlled blasting is used in this project. In this blasting technology, single layer charge arrangement, the largest charge divided into two charges, Nonel millisecond delay controlled initiating methods are used. Excellent blasting results have been obtained.
