摘要
系统地总结了国内外现有金属矿地震勘探技术及其研究与应用现状,其中包括岩石物理性质分析和散射波场特征分析等基础研究、区域普查地震技术、二维和三维地震成像技术及井下地震勘探技术。指出反射波地震方法是目前金属矿地震勘探的主要方法:国外使用的主流方法是在利用反射波成像处理技术得到的实测成果数据体中,采用强散射特征分析等属性分析方法圈定矿体;国内主要是利用常规反射波方法进行资料处理,在反射剖面上利用散射波概念进行地质解释。同时指出,金属矿勘探所涉及的特殊地震地质条件使得金属矿地震勘探问题落入地震波散射领域,而现有技术中缺少从散射观点出发进行地震资料采集、处理和解释的理论与配套技术。进而强调研究基于地震波散射理论的散射波地震技术是金属矿地震勘探技术的发展方向。
This paper reviewed the researches and applications of seismic techniques in mining exploration in detail,including the fundamental researches composed of acoustic properties and scattering characteristics,regional reconnaissance studies,2-D and 3-D surface seismic imaging and down-hole seismic ima- ging,and pointed out the main seismic method used in mining exploration is reflected wave methods at present.Intense seis- mic scattering response analysis on data processed by reflected wave imaging techniques is used to delineate ore-bodies in for- eign countries,while methods of interpretation with scattered wave views on data acquired by means of reflected wave tech- niques are used in China.For mining exploration,the complex problems involved fall within the seismic wave scattering area, suggesting that they require to be solved completely by the scattered wave seismic techniques,which are not available now,and which are the future direction of seismic techniques for mining exploration.
