摘　　要：地震勘探具有勘探深度深、分辨率高的优势,是深部矿产资源勘探不可或缺的技术力量,充分认识金属矿地震勘探的特点是保障金属矿地震勘探成功实施的关键.本文从主动源和被动源地震两个方面介绍了在金属矿地震勘探方面的进展和展望.主动源方面,介绍了反射地震目前在采集、处理和解释方面的进展,并对直接开展主动源地震金属矿勘探存在的问题进行了正演模拟,同时采用闽西南推覆控矿区域的地震勘探示例,说明了针对性技术在金属矿地震勘探实践中的作用.被动源地震具有绿色、便捷、低成本的特征,本文以被动源面波和体波成像的为例,介绍了被动源地震勘探的基础理论,并以大桥金矿勘探为例,展示了其在金属矿探测中的有效性和应用前景.主动源地震和被动源地震未来在深部矿产勘探领域的作用将随着勘探成本的降低而越来越重要.Seismic exploration has the advantages of deep exploration depth and high resolution.It is an indispensable technical method for deep mineral resource exploration.There is no essential difference between mineral seismic exploration and oil and gas seismic exploration.It is the key to ensure the successful implementation of mineral seismic exploration by understanding the characteristics of mineral seismic exploration.This paper introduces the progress and prospects of mineral seismic exploration from two aspects:active source and passive source seismic.In terms of active source,the current progress in the acquisition,processing and interpretation of reflection seismic is introduced,and the problems existing inactive source seismic exploration for mineral deposits direct indication are simulated.At the same time,the seismic exploration example of the thrustcontrolled ore area in southwestern Fujian is used to illustrate the role of targeted technology in the practice of mineral seismic exploration.Passive source seismic is green,convenient and lowcost.Taking passive source surface wave and body wave imaging as examples,this paper introduces the basic theory of passive source seismic exploration,and takes the exploration of Daqiao gold mine as an example to demonstrate its effectiveness and application prospects in mineral exploration.Mineral seismic exploration is a seismic exploration method that aims to detect mineral deposits.It is not a new seismic exploration method.All active and passive source seismic exploration technologies used in engineering,oil and gas,etc.can be applied to solve specific mineral detection problems.The role of active source seismic and passive source seismic in the field of deep mineral exploration will become more and more important in the future as the exploration cost decreases.
