洪家渡水电站面板堆石坝采料爆破

Quarrying blasting of rock-fill dam with concrete facing of Hongjiadu Hydroelectric Station

详细描述了洪家渡水电站面板堆石坝料石爆破开采设计过程,分析了料场地质条件,并通过试验研究建立了块度预报模型,给出了料石爆破参数对同类爆破工程有参考价值。

In this paper, the design of excavating rock material of rock-fill dam with concrete facing of Hongjiadu Hydroelectric Station is described in detail and the blasting parameters are presented. A lump prediction model is established by test data. It is used as reference to similar engineering.
