【摘要】 随着我国国民经济的快速发展,矿产资源需求与保障能力之间的矛盾日益突出,金属矿勘查已成为当前地质工作的重要任务。找矿深度的不断增加,使得找矿难度也随之加大,这就为地球物理勘查技术提供了发展空间。本文对高精度航空磁测技术、航空电磁测量技术、航空放射性测量技术、航空重力测量技术、地面电磁测量技术、井中地球物理测量技术、金属矿地震勘探技术、天然地震流动台阵技术和深地震主动源剖面探测技术等进行了总结,较为全面地阐述了这些方法技术的研究及应用现状。这些方法技术是当前矿产勘查有效的地球物理方法技术,或是近年来研发的新方法、新技术,在新一轮的矿产勘查中具有广阔的应用前景。但是,地球物理勘查观测结果的多解性,又困扰着资料的正确推断解释,因此,如何正确选择和合理运用这些方法,充分发挥方法技术各自的优势,就显得尤为重要。本文重点围绕方法技术概况、基本原理、技术特点、应用范围和应用条件、应用实例及应用效果等方面进行归纳、总结,以期对金属矿勘查实践有所指导。更多还原

【Abstract】 With the rapid development of China’s national economy,the contradiction between mineral resources requirements and support capabilities have become increasingly prominent.The metal ore exploration has become an important task of geological work.Increasing the depth of exploration,so also will increase the difficulty of prospecting,geophysical prospecting techniques which provide for the development of space.This paper summer arises the technique of high precision aeromagnetic,airborne electromagnetic measurement techniques,airborne radioactivity measurement techniques,airborne gravity measurement technology,ground electromagnetic measurement techniques,borehole geophysical measurement technique,the metal mining seismic exploration technology,portable seismic array and deep seismic detection techniques,etc.,summarizes a more comprehensive exposition of these methods and application of technology.These methods and techniques are currently effective mineral exploration geophysical methods and techniques developed in recent years,and of a far-ranging application prospect in a new round of mineral exploration.However,multiple explanations of geophysical exploration results have long imposed difficulty on application of geophysical methods.So how to choose and employ these methods and how to take full use of their own advantages become particularly important.This overview just summarized achievements made in methods and techniques,basic principles,technical characteristics,application scope and conditions,case study and results,in hope of giving some guidance for metallic ore exploration.更多还原
