摘　　要：物探方法与技术作为开展深部找矿工作的一种主要手段,越来越受到矿产勘查界的广泛重视与应用。地下物探方法利用现有的钻孔或坑道,对钻孔底部或外围进行进一步的勘查很有优势,更适用于深部找矿。论述了井中磁测、井中激发极化法、井中(坑道)充电法、坑道(井中)自然电位法、井中电磁法等几种常用的金属矿地下物探方法。从应用实例着手,分析和总结了各种方法在深部找矿中所发挥的优势与作用,提出应重视并重新认识地下物探技术的地位和作用,增强相关技术的研发与应用等建议,为矿产勘查、开发、开采与施工提供重要的信息指导。As main tools in deep ore-prospecting, geophysical prospecting methods and technology are more and more applied in mineral prospecting industry. Among which, geophysical prospecting is quite helpful when it is used at the bottom or peripheral part of the drillhole based on existing drillhole or pitting engineering. In this paper, a number of subsurface geophysical exploration meth- ods such as downhole magnetic measurement, downhole induced polarization method, downhole （pit） ＂mise-a-la-masse＂ method, pit （downhole） self-potential method and downhole electromagnetic method commonly used for metallic deposits; starting from solved examples, the author analyzed and summarized advantages for all these methods used in deep-prospecting, it＇s suggested to put more emphasis on sub-surface geo-physical technology, as well as research and development of relevant technology, which could be very important information guide for mineral prospecting, development, mining and construction.
