水利水电工程施工中隧洞钻孔爆破技术

Tunnel Drilling and Blasting Technology in the Construction of Water conServancy and Hydropower Projects

以水利水电工程施工中的隧洞钻孔爆破技术为论述方向。首先对隧洞钻孔爆破注意事项进行论述,隧洞钻孔爆破注意事项主要以制炸药的用量、隧洞的掘进施工、钻孔爆破循环施工、装置和卸载方法及炮孔的布置布局为主。其次,对相关注意事项分析后选取A水利水电工程隧洞钻孔爆破施工为例。通过对A水利水电工程隧洞钻孔爆破的具体实施,旨在为我国水利水电工程施工中隧洞钻孔爆破提供理论指导与帮助。

The precautions for tunnel drilling and blasting are discussed.Firstly,the precautions for tun⁃nel drilling and blasting mainly include the amount of explosives,tunnel excavation construction,drilling and blasting cycle construction,device and unloading method,and the layout of blast holes.Secondly,af⁃ter analyzing the relevant precautions,the tunnel drilling and blasting construction of a water conser⁃vancy and hydropower project is selected as an example.Through the concrete implementation of tunnel drilling and blasting of a water conservancy and hydropower project,this paper aims to provide theoreti⁃cal guidance and help for tunnel drilling and blasting in the construction of water conservancy and hydro⁃power projects in China.
