大连港海底深水深孔炸礁技术研究

Deep Hole Reef Blasting in Dalian Port

大连港海底深水炸礁工程存在着水深、流急、浪高、潮差大等恶劣情况,为此选择了800 t液压升降炸礁船作业,采用了信息化数字测量定位技术、精准钻凿炮孔、严格防护起爆网路等措施,顺利完成了深水炸礁工程,爆炸效果良好。介绍了该工程的爆破设计及关键施工技术。

Owing to the terrible condition of deep water,hurry flow,big wave and tide,the 800t hydraulic lift ship was chose to work in reef blasting at Dalian port.The digital measurement location technology,precision drilling hole and firing circuit with strict protections were used to assure the deep water reef blasting successfully and got good results.The blasting scheme and key construction technology was also introduced.
