摘　　要：三道岔金矿床是夹皮沟成矿带内的典型金矿床。针对以往提交的浅部资源开采殆尽,矿山面临资源危机的现状,亟须开展深部找矿工作,并取得实质性的找矿突破。通过梳理地质资料和科研成果,总结矿床地质特征和控矿规律,提出深部找矿新方向,通过工程验证,成功在3号含金断裂深部探获了矿体的第二富集段,总结找矿经验和认识,为同类矿床找矿提供借鉴。Sandaocha Gold Deposit is a typical gold deposit in Jiapigou metallogenic belt.Challenged by depleting near-surface resources,the mine is facing a reserve crisis.So it s urgent to carry out a deep prospecting project and achieve a significant prospecting breakthrough.The paper read through geological data and scientific achievements,summarized the geological characteristics of the deposit and the ore-controlling law,and put forward the new direction of deep prospecting.Verified by engineering practice,a second enrichment section was achieved in the ore body deep in the No.3 gold-bearing fault.The study summed up prospecting experience and understanding,providing references for prospecting in similar deposits.
