中山市阜沙镇鸦雀尾水利枢纽工程石方爆破作业技术措施分析

Analysis on rock blasting operation technical measures in Yaquewei Water Control Project in Zhongshan Fusha

中山市阜沙镇鸦雀尾水利枢纽工程对于土石方开挖技术要求很高,尤其对于石方爆破技术要求方法要多种,技术要先进,准备要充分。本文结合工程实际,对石方开挖过程中所遇到的深孔梯段微差爆破技术、预裂爆破和光面爆破技术进行了阐述,同时对爆破安全技术控制和石方爆破安全防范措施进行了详细说明,意在为类似工程提供参考。

Yaquewei Water Control Project in Zhongshan Fusha has high requirements on earth rock excavation technology.Especially for rock blasting technology,the method should be advanced,and the preparation should be sufficient. In the paper,the project practice is combined for describing deep hole millisecond blasting technology,pre-splitting blasting and smooth blasting technology in the rock excavation process. Meanwhile,blasting safety technical control and rock blasting safety precautions are described in detail aiming at providing reference for similar projects.
