大岗山水电站位于高山峡谷地区，坝址附近缺乏满足筑坝要求的砂砾石料。工程前期对坝址上下游若干人工骨料场开展了普查工作，初步确定了若干个人工料场，经综合比选，最终选择了棱子坝和雨洒河两个料场开展了详查勘测工作。主要阐述了棱子坝料场的勘察过程，对料源质量和储量状态进行了检测分析与评估，重新确定了料场的开采范围，提出了具体开采时应注意的问题和建议。
大崗山水電站位于高山峽穀地區，壩阯附近缺乏滿足築壩要求的砂礫石料。工程前期對壩阯上下遊若榦人工骨料場開展瞭普查工作，初步確定瞭若榦箇人工料場，經綜閤比選，最終選擇瞭稜子壩和雨灑河兩箇料場開展瞭詳查勘測工作。主要闡述瞭稜子壩料場的勘察過程，對料源質量和儲量狀態進行瞭檢測分析與評估，重新確定瞭料場的開採範圍，提齣瞭具體開採時應註意的問題和建議。

There is a dearth of qualified sand and gravel material near the Dagangshan Hydropower Station that is located in valley area, so geological survey searching for artificial aggregate fields has been conducted near the dam site. Through compre-hensive comparison and selection, two aggregate filed of Lengziba and Yusahe were chosen, and the specific survey was carried out. The survey of Lengziba was introduced. The quality of the material source and the storage state were tested, analyzed and e-valuated, and the area for mining was re-determined. The problems that should pay attention to and suggestions in mining were proposed.
