摘要
文中介绍了山西张峰水库龙王沟堆石开采爆破设计,通过对爆破设计参数的选择,采用周边预裂爆破及深孔爆破,应用孔外微差孔内延时爆破技术及在龙王沟堆石料开采爆破开挖中采用了保护层一次性开挖,取得了良好的施工效果。
In this paper, the blasting design of quarrying in Longwang Ditch for constructing rockfill dam of Zhangfeng Reservoir is introduced. Through the selecting design parameters of blasting and due to using presplit blasting, deep hole blasting, millisecond blasting outside hole, delayed blasting inside hole and overburden stripping for once in Longwang Ditch Quarry, the good construction effect is obtained.
