摘　　要：本文在收集、整理大量资料的基础上,采用探采对比、统计归纳等相结合的研究方法对重要有色金属、贵金属、稀有金属老矿山深部及外围合理勘查程度进行了系统研究。认为:老矿山深边部勘查其勘查阶段分普查和详查。普查以确定下步勘查开发总体方向、范围和规模为重点。详查则主要根据普查工作成果,结合老矿山实际情况进行系统的勘查工作,估算控制的矿产资源储量,并通过预可行性研究,做出是否具有进一步工业开发价值的评价,为开发提供依据。老矿山勘查类型和勘查间距应及时根据矿床类型和矿体规模、形态、品位等特征和变化进行调整并重新研究确定。老矿山勘查深度以500m^2000 m较适宜,尤其是500m^1000m深度是当前最重要的深部找矿区域。on the basis of collecting and sorting out a large amount of data,this paper systematically studies the reasonable exploration degree of the deep and periphery of the important non-ferrous metal,precious metals and rare metal mines by combining the research methods of exploration and mining contrast and statistical induction.It is considered that the exploration of deep and marginal mines in old mines is divided into general investigation and detailed investigation.The census focuses on the overall direction,scope and scale of the next exploration and development.Detailed investigation is mainly based on the results of the survey work,combining the actual situation of the old mine with the systematic exploration work,estimating the reserves of the controlled mineral resources,and making the evaluation of the further industrial development value through the pre feasibility study,and providing the basis for the development.The exploration types and exploration intervals of the old mines should be adjusted in time and re studied according to the types of ore deposits and the size,form and grade of ore bodies.The exploration depth of old mines is more suitable for 500m^2000 m,especially 500m^1000m depth is the most important deep prospecting area at present.
