摘　　要：芦家坪银多金属矿床原属于银洞沟矿集区,为典型板块碰撞造山型矿床。矿体产于(变)细碧岩或(变)细碧凝灰岩中,形态严格受含矿构造蚀变带控制,多呈脉状、不规则状、似层状、透镜状、舒缓波状,具有膨大狭缩、尖灭再现的特点。矿体中部为菱铁矿层,是矿体的标志层,可作为深钻中矿体对比连接的主要依据。通过整理近年来的勘查资料,结合前人研究结果及矿体在走向和倾向上的分布特征,对深部进行成矿潜力验证,探获了矿体。通过对深钻探获矿体的对比,认为Y3矿脉深部具有巨大成矿潜力。The Lujiaping Silver Polymetallic Deposit originally belonged to the Yindonggou high ore concentration area and is a typical plate collision orogenic type deposit.The ore body occur in(metamorphic)spilite or(metamorphic)spilite tuff.The morphology is strictly controlled by ore-hosting tectonic alteration zone.The ore bodies mainly take the form of veins,irregular,stratiform,lens,gentle waves,and are characterized by swelling and narrowing,and pinching out and reappearance.The middle part of the ore bodies is siderite layers that are the marker of the ore bodies and can be used as main basis of ore body comparison and connection in drill holes deep in the mine.By collating exploration data of recent years,based on predecessors’research and the characteristics of ore body distribution in strike and inclination,the metallogenic potentials deep in the mine are verified,and ore bodies are found.By comparing the ore bodies found through drill holes deep in the mine,it takes that deep in Y3 ore vein,there are great metallogenic potentials.
