硐室爆破在仙口水电站堆石坝填筑料开采中的运用

Application of chamber blasting in extracting the embankment material of the rockfill dam of Xiankou hydropower station

硐室爆破开采面板堆石坝填筑料在级配上能达到设计要求,具有备料时间短和施工干扰少等优点,对于堆料场地狭窄、填筑强度高、备料时间短的项目有很大的优势.

The chamber blasting has the merit of short time in preparing for construction material and little disturbance of construction material in order to reach the design graduation demand in extracting the embankment material of rockfill dam.It can solve the problems such as narrow dumping site and high material-filling quantity every time interval.
