爆破直采技术在面板堆石坝工程中的应用

Application of Blasting Direct Mining Technology in Faced Rockfill Dam

面板堆石坝的坝料开挖直接制约工程进度,按传统工艺开挖费时费工,严重影响施工进度,本工程在利用坝体级配料开挖中采用爆破直采技术,加快了坝料开采速度,效果显著。经过爆破试验,优选爆破参数,为获取粒径与级配符合设计要求及成本低廉的坝料创造了有利条件。详细介绍了试验过程,并对试验结果进行了分析。

Dam material miming directly affects project progress of faced rockfill dam. Blasting direct mining technology speeded up the mining velocity compared with time and labor-consuming traditional technology. Blasting parameters were optimized by blasting tests. The paper introduced testing process with the analysis on testing result.
