摘　　要：心墙堆石坝约80%以上的筑坝材料来自石料场;而石料场是堆石坝"粮仓",必须重视其各阶段开采规划工作,才能从根本上保证工程建设的"快、好、省"三大目标。为此,从长河坝水电站心墙堆石坝石料料源在不同阶段的施工规划与施工期间的动态开采优化分析研究入手,最终选择距离近、地形好的上游料场作为主料场,充分利用建筑物开挖料,及时调整开采坡比等动态优化方案,取得了石料场开采总运输量比投标方案降低约25%,料场边坡支护面积比投标方案降低约71%的效果。About 80 percent filling material of core-wall rockfill dam comes from quarry, so it is necessary to pay attention to the mining planning in all stages so as to fundamentally achieve three construction goals of ＂Rapid-construction, High-quality and Good-economy＂. For this purpose, the mining planning of quarry and the dynamic mining optimization during the construction of Changheba Hydropower Station is analyzed. By selecting the upstream quarry as main filling material source which closer to dam site and with favorable topography, making full use of foundation excavation materials, and timely adjusting excavated slope ratio, the total mining quantity is about 25% lower than the volume in bidding scheme, and the slope supporting area of quarry is about 71% lower than bidding scheme.
