中文摘要:为进一步拓展地震勘探方法在金属矿勘探中的应用,寻找到更多的隐伏固体矿产,文章应用复数地震道分析方法将地震波中以三瞬信息为主的动力学信息提取出来。这些信息形象直观地反映了地下矿体的赋存状况和展布形态从而达到勘探的目的。通过对某地已知和未知矿区实测地震波动力学信息的提取分析和钻探验证证明地震波三瞬信息对地下岩体成像效果好,为地下金属矿藏探测提供了一个新的有效手段。

Abstract:Nowadays it is increasingly important for geophysical experts both at home and abroad to find more concealed ore deposits by means of seis mic exploration. The authors conducted experimentation in some known and unknown metallogenic zones in the middle andlower reaches of the Yangtze River. The derivation, analysis , interpretation and application of seis mic wave dyna mics were studied . The dyna mic infor mation revealed that there existed nearly 20 concealed deposits. Subsequent drilling and test in the Mg rock body de monstrated that theseis mic tri-instantaneous information was effective in imaging the ore deposits . The test proved to be a wonderful success . This method provides a new effective means for metallic deposit exploration.
