Research on Exploiting Ⅲ_B Materials by Chamber Blasting in Gangkouwan Reservoir

为了探索洞室爆破法开采面板堆石坝主堆石料 (ⅢB 料 )的可行性 ,在安徽宁国市港口湾水库主料场进行了一次洞室爆破试验 ,试验取得了成功。本文详细介绍了该次试验的设计及爆破情况 ,总结了采用洞室爆破法开采ⅢB级配料的有关规律。

In order to explore the feasibility of exploiting Dam Materials(Ⅲ B) for rock-fill dam by chamber blasting. A trial was done at Gangkouwan Reservoir, Ningguo, Anhui. In this paper, the desig and implement of this blasting was introduced. Some experience was summarized up about exploiting dam materials(Ⅲ B) for rock-fill dam by chamber blasting.
