摘　　要：由于微细浸染型金矿床普遍具有矿体赋存形态复杂、矿体与围岩界线不明显这一特点,使得该类型的矿山在开发的过程中面临开采损失贫化难以控制、采矿效率低等问题。在贵州省安龙县戈塘金矿对该类型的金矿床进行物探勘探研究,物探方法采用现阶段已发展得比较成熟的高密度电法。高密度电法具有观测工作简单、功效高、采集信息量大等特点,能勘探出地下岩层的地质构造、地质灾害等信息。本次利用高密度电法在已知矿体上进行物探勘探工作,利用矿山已有资料验证该方法的可行性,也证明了该方法在确定微细浸染型金矿形态技术中并不适用。The fine disseminated gold deposits are complex forms of ore bodies, as well as the ore bodies and surrounding rock of complex boundary are not obvious, for the types of mining there are some problems the difficult control of loss and dilution in mining and the mining low efficiency in the development process. A geophysical ex- ploration research for this type about Getang gold deposit of Anlong Country of Guizhou Province is maken. Geo- physical method uses the high density electrical method which has been developed relatively mature at the present stage. The high density electrical method has the characteristics of high efficiency, simple observation, meanwhile it can collect large information and prospect the underground rock formation of geological structure and geological disaster. The use of high density electrical method to geophysical exploration work in the known orebodies, using mine data to demonstrate this method＇ s feasibility, show that the method don＇ t apply in the determining technology of the fine disseminated gold deposit form.
