摘　　要：电阻率法以岩矿石电阻率差异为勘探基础,具有装置简便、能有效处理复杂地形等特点,在有色金属勘探中具有独特的优势,是有色金属勘探的最重要方法,其理论方法、观测仪器和反演解释技术不断更新完善。观测理论和方法技术由简单模型和特定装置向二维、三维发展,甚至出现跨维的观测方式,以求实现观测效率与效果的平衡。电阻率法仪器装备也同步发展,由单一装置设计向分布式、阵列式仪器发展,其自动化程度、观测精度和数据量都在不断提高。观测数据的反演解释同样也向符合实际勘探需要的非线性三维和智能化联合反演发展,其精度和可靠性越来越好。这些方法技术的发展不仅进一步巩固了电阻率法在有色金属勘探中的重要地位,而且还有向金属矿山环境和地质灾害监测与探查方面应用不断拓展的趋势。The direct current resistivity method, based on the resistivity difference of rock and ore, has the advantages of simple equipment and dealing well with complex terrain, and has been the most important method in non-ferrous metal exploration. The theoretical methods, observation instruments and inversion and interpretation techniques were constantly updated and improved. Specifically, the theory and method for field observation have developed from simple models and specific devices to 2D and 3D observation methods and even appeared crossdimensional observation methods to balance the observation efficiency and effect. The direct current resistivity instrument and equipment are also developing synchronously, from single device design to distributed, array instrument development, and the degree of automation, observation accuracy and data volume are constantly improving. Besides, the inversion and interpretation of observation data are developing towards the nonlinear 3D and intelligent joint inversion, which is in line with the actual exploration needs, and the interpretation accuracy and reliability are getting better. The development of these methods and technologies has further consolidated the important position of the direct current resistivity method in the exploration of non-ferrous metals, and at the same time, its application has been expanded to the monitoring and exploration of metal mine environments and disasters.
