摘　　要：由于金属矿区地质构造的复杂性和复杂的地表条件,适合于探测层状介质的地震反射方法技术在金属矿勘查中的应用受到了限制。为提高地震记录的横向分辨率,探测复杂的地质构造及隐伏岩体等,需研究相应的地震方法技术,地面地震层析技术在金属矿勘查中的试验研究就是为解决上述问题而开展的。本文就非线性地面地震层析技术的基本原理进行了阐述,并就该方法在金属矿勘查中的试验效果进行了讨论。Due to the complexity of geological structures and surface conditions in metallic ore areas, the seismic reflection method suitable for detecting bedded media is rather limited in metallic ore exploration. In order to detect complex geological structures and concealed rock bodies and improve horizontal resolution of the seismic record, we must study the corresponding seismic techniques. For the purpose of solving the above problems, the tentative application of surface seismic tomography to metallic ore exploration has been developed. This paper sums up the basic principle of nonlinear surface seismic tomography and discusses the experimental results of its application to metallic ore exploration.
