摘　　要：溪口砂金矿属于高河漫滩多巨砾砂金矿床，适宜用条带块段开采，分层开挖，腐植土单独堆放，粘土层和不含金矿砾层用推土机剥离，矿砂层用前装机回采的旱采旱剥方式。本文取材于溪口砂金矿的开采实践，对这一开采方式的剥离、回采、复田工艺作了系统阐述。Xikou high-bed gravelly gold placer is suitable for such a dry mining plan,i. e. strip block stoping, slicing excavation,individual disposal of muck soil, dozer strippingof clayed soil and gravels without gold, and tront-end loader mining of gold placer,Bsaedon the mining practice at Xikou gold plcaer,a systematic introduction to stripping,stopingand reclaiming technology in this mining plan is made.
