从金属矿地震方法的试验效果探讨其应用前景
|
摘要
由于金属矿区地质构造的复杂性,金属矿勘查中的地震方法技术还处于试验应用研究阶段。几年来的深入试验研究不但使地震方法技术取得了较大进展,而且在利用地震方法探测控矿构造和寻找与隐伏金属矿有关的局部不均匀体等方面也取得了明显的地质效果。笔者就近几年在金属矿地震试验研究中取得的一些地震地质试验结果进行了总结,认为反射波地震方法在探测沉积层控矿床和控矿构造方面效果较好,利用散射波地震方法可探测与矿体有关的地下局部不均匀体,进而,确定隐伏矿体的位置。在此基础上,探讨了地震方法寻找深部隐伏金属矿的应用前景。
Due to the complexity of geological structures in metallic ore areas,seismic techniques applied in metal exploration are still in the experimental stage.Through several years of deep-going experiments,not only major progress in seismic techniques have been made,but pronounced positive geological results have also been obtained in using the seismic method to detect ore-controlling structures and look for local inhomogeneous bodies related to buried metallic ore deposits.The authors summarize some results of seismic and geological experiments obtained in the seismic experimental study of metal exploration and consider that the seismic reflection method can yield good results in the exploration for sedimentary stratabound ore deposits and ore-controlling structure and that the scattering wave method is useful for the study of subsurface local inhomogeneous bodies related to orebodies and the determination of the location of hidden orebodies as well.On that basis,the prospects of application of seismic methods in looking for buried metal deposits at depth are discussed.
