摘要(Abstract):

在沟后面板坝修复工程中 ,根据现场的实际条件选用硐室爆破开采筑坝石料。文中介绍了爆破方案设计 ,包括药室布置、爆破参数选择、药量及装药结构、起爆网路等。随机抽样统计结果表明 ,大块率为 7%~ 8%。此外 ,对硐室爆破成本进行了分析。
In reconstruction project of Gouhou concrete faced rockfill dam,chamber blasting was selected for exploitation of the dam rock material In this paper,the blasting design is introduced including the layout of charged chambers,the selection of blasting parameters,charge weight and charging structure,priming network and others The statistic result of random sampling has showed that the boulder rate is 7%~8%. In addition,analysis on the cost of chamber blasting is carried out
