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。
The project of Raftingao Water Conservancy Project in Fusha Town, Zhongshan Municipality is very demanding for the technology of earthwork excavation. In particular, it requires a variety of methods for the blasting technology of stone blasting. The technology should be advanced and fully prepared. Combined with engineering practice, this paper describes the deep-hole bench blasting technique, pre-cracking blasting and smooth blasting technology encountered in the stone excavation process. At the same time, the blasting safety technology control and stone blasting safety precaution measures A detailed description, intended to provide a reference for similar projects.
