摘　　要：砂金经过洗选工艺处理后可以得到大颗粒的黄金,天然的原生金块都比较大且多埋藏于砂砾含水层中,或者是下部基岩面以及其裂缝中。本文详细探讨如何通过特殊井巷结合疏干法进行金矿的开采。Placer gold can get large grains of gold after washing process, the natural primary gold blocks are relatively large and often buried in gravel aquifer, or the lower bedrock surface and its cracks. This paper discusses in detail how to exploit gold mines by combining special wells with dredging.
